Fred (FAR Circuits) doesn't recall the colorburst transmitter that's
been discussed recently.  We've been told it was the QRP-NE#1, but
that still doesn't ring a bell with Fred.

Perhaps the board was done for an individual, who asked Fred to do a
run of 50 or so, and Fred sent the artwork back with the boards.  Or
maybe Fred just mis-filed the artwork.  In any case, he cannot find
the artwork for this board.

If anybody has a copy of the article, and the board layout, please
send it to Fred at FAR Circuits   18N640 Field Ct   Dundee  Il  60118.
It will be of great help to those needing the board for this
transmitter.

Fred says Thanks in advance.

(we have it easy - we live about 15 miles from Fred, and he's been
very helpful getting boards ready for various articles and whatnot for
us, while we've kept his drilling machine computer running for him.

Anyone know about old FT-243 type holder crystals with knobs on them?
I just got one that is marked 7044-7053 K.C.  I have been in ham radio
for 25 years and managed to avoid them all this time.  Is it a crystal
with a little cap inside?

Gang,                      6/21/93

I talked with Dave, NN1G, Friday evening, and asked
him why FAR cannot supply Colorburst rig PC boards.

Dave said that FAR circuits returned the artwork to
him after the original order for 50 boards.

That is why FAR does not have the artwork now  !!!

Dave said he will ship the artwork back to FAR this week.

PC board  QRP-NE #1.



PS.....
Dave also said that one of our more ambitious, personable
Internet members is about to become internationally famous
in the QRP world.
I cannot mention a name, but as soon as it becomes
official from ARCI, and confirmed by the rest of the
board, I will......

Subject: ftp-able pc artwork

Hello fellow QRPers -

   With the recent discussion of FAR circuit boards for
the NE-QRP Colorburst rigs, I was wondering if there would
be interest in  starting a collection of ftp-able pc artwork.
This would allow the homebrew pc builder to satisfy
his/her habit!

    We would have to decide on a format that would be
easily used with the major image manipulation programs
(i.e.  adobe photoshop, etc).  Maybe a first step would
be to see how many people would really be interested in
this service.  And then there's the issue of where to
store them...

    Comments?  Ideas?

Subject: FT243 with knobs

Clark,
I remember seeing some of these where the knob on the outside varied the
pressure to the plates that surround the crystal on the inside. It gave you
a bit of VXO control. I forget if more pressure was higher or lower
frequency. I don't recall any modifications with caps, but I imagine that
would be possible, although it would make more sense to put the cap and
coil in the transmitter so it would work with all crystals.

I remember the days of etching or grinding the crystals (comet and a piece
of glass) to raise the frequency and then "leading" them with a #2 pencil
to bring them back down. Chasing dx with a pencil and a screwdriver to move
the crystal - those were the days.  :-)

I Think I may have just dated myself....

To All,

I got a copy of PADS from the location below. I can't comment on it yet
as I haven't really used it yet.

If you want a copy, let me know and I'll try to figure out how to get
it to you. I have also heard that you can get a copy directly from the
company as a demo. The files are about 2.5 MB compressed.

Re; Designing Printed Circuit Boards;



I understand that FAR offers an outstanding artwork
service, providing a PC board layout and artwork from
your parts and lay-out sketch, and that the service is
inexpensive and the quality and pc board is excellent.

Hello Kevin:

You mention the days when chasing DX with a pencil and screwdriver to adjust
your freq. (crystals).  I remember that myself.  I used iodine on the crystal
instead of pencil lead, but used the screwdriver to scrape the crystal also.

Funny stuff.  Anyway, it seems the consensus is that the knob varies pressure
on the crystal slab inside the FT 243.  Funny little beast.  It chirps inside
my T-60 (that dates ME!  My first transmitter.....) whereas my standard
crystals do not.  Think I will dismantle it for a look-see.

Subject: FD ARRL sections


Gang,

for field day, every year, there are some who don't know the proper
abbreviations for the sections.  here is a list (hopefully it is
accurate, but some typos may have slipped in and i know i will hear
about them  ;-) )

call area  sections

1  CT EMA ME NH RI VT WMA
2  ENY NLI NNJ SNJ WNY
3  EPA DE MD WPA
4  AL GA KY NC NFL SC SFL TN VA PR VI
5  AR LA MS NM NTX STX WTX OK
6  EB LAX ORG SB SCV SDGO SF SJV SV PAC
7  AZ ID MT NV OR UT EWA WWA WY AK
8  MI OH WV
9  IL IN WI
0  CO IA KS MN MO NE ND SD
VE MAR QUE ONT MB SK AB BC

list made up from arrl section map in arrl operators handbook.
last SS i worked was before all the new sections!!  so the clean sweep
list didn't help at all...... :-(

so gang, memorize it.  of course, there will be some operators on
the other end that want repeats because you are using the correct
abbreviation and they didn't catch it and there will be unexpected
abbreviations received from them.  keeps us all on our toes i guess.
check which section you're in before the games begin.  field day
chairperson will probably already know this.

of course, with everybody keeping their old calls independent of
geographical location, a section doesn't always correspond with
the stations call area......  i won't get on the soapbox on this one.  ;-)

notes:  PAC is pacific for KH6s on the islands
        AK  is Alaska for KL7s in the north
        PR  is Puerto Rico
        VI  is Virgin Islands

hint:  wanna increase your CW speed?  work FD and SS.  your code speed
       will really go up in a hurry.  get an Elmer and help them with logging
       and dupping to start.  requires earphones for both in most cases.

after this test you'll be copying morse from the shower, the fans, and lots
of background noise.  ;-)

good luck in the TEST (Emergency Preparedness).  watch out for the critters
and Murphy.  this is the largest gathering of radio amateurs to see who can
destroy the most equipment.....  :-)  war stories to follow next week.

Subject: Which QRP rig?

Hi,

I was at a local hamfest this weekend and nearly came home with an MFJ qrp
rig for 30 meters. I only decided to hold off because I was a little leery
of MFJ and because I didn't know if there was a 'clear winner' in the
battle of the new little qrp rigs. I have an HW-8 and so I am well
aquainted with direct conversion receivers. I was thinking that I'd like to
go with a single signal receiver with a nice filter.  The only two I am
aware of are the A&A engineering unit that is designed by Gary Breed, and
the MFJ. I noted on the schematic that the MFJ starts out with an NE602,
and that worried me a little. Both seem to make about 4-5 watts. The
cabinet on the A&A unit is pretty large, the MFJ had a nice little cabinet
and decent tuning feel. Can anyone give me their impressions of how these
two compare? Jeff, I think you are doing some sort of comparison between
units, aren't you?

Thanks,

Subject: MXM Transceiver


Gang,

Jeff Gold(AC4HF), famous QST author and member of this group, periodically
pings me about the new MXM simple transceiver.  i've gotten mine in
a case and going finally.  too many trips and not enough room for
equipment on the road to finish sooner.  missed qso with the famous
Jim Kearman.  one of these days.

i'll post final dimensions of the board, as i don't have them here
at the office.

the receiver section is the SuperRX plus an addition IF stage in
the front end with Cohn crystal filter for 10Mhz IF followed by
455 Khz IF, thus a dual conversion receiver.  bandwidth is about 500
cycles with the filter.

i was on 40 meters early yesterday morning.  i heard VE3s until about
10 am CDT.  band was very long and signals pretty strong for this time
i year, INMHO.  lots of W1s and W2s on.

i had mxm rcvr and icom 725, yaesu ft-707, and ohr spirit rcvrs on 40
meters.  the mxm was the most sensitive.  it heard signals the others
did not.  qrn was present as tropical depression was to the east of
texas yesterday morning and some rain showers in northern part of state.

the mxm receiver has more noise than the ohr spirit and about the same
as the icom 725, which i consider a noisy receiver with respect to
background noise levels.  the yaesu ft-707 quieter but lacks some
in sensitivity relative to the mxm.  the yaesu ft-707 is a much
better receiver than the icom 725.

pluses for mxm rcvr -
o  good sensitivity
o  good stability
o  cheap
o  good selectivity

minuses -
o  more difficult to align for the general builder, but not impossible
   just requires a little more time and effort on the part of the
   builder.  i used the scope, frequency counter, and great care to
   align.  but i do this with everything anyway.
o  a little more background noise internally
o  no RIT, but not a severe handicap to me


transmitter is vfo controlled with osc for receiver and another
mixer (NE602 mixer).  i've got mine tuned to 500mW out into dummy
load.  with 2SC799 final PA, should be able to get 3 or more out.

qsk without relay.  a real plus to me.

parts complement;

6 ics - 4 NE602s, MC3340, and LM380
6 transistors - 4 2N2222s, 2N3906, and 2SC799.

7 IF transformers

i'd say the board is about 3.5 x 4.5.  i'll just have to go back
and measure it.

more details to follow.

ciao,

Aloha everyone,
   I remember my old 1965 or 66 edition of the ARRL's UNDERSTANDING AMATEUR
RADIO talking about how to change the freq of an xtal by the previously

there.
   As I mentioned  last week, I've come across a couple of books that
contain a goldmine of easy-to-build QRP circuits; xmtrs and rcvrs, and
other goodies. Both books are out of print. I'll attempt, from time to
time, to  `draw' the schematics and send them along via the net. These
should be really fun to build and play with.

    I had to look twice and see whether this thread came from the

    both have a high "tinker factor" but at opposite ends of the
    portablility scale!!!)

    Ahyhoo... in my limited experience (messing around at work years
    ago, when I shoulda been working) wiping the end of a strand of
    solder over the crystal blank would also lower the freq of
    the unit, with more stable results than pencil lead. It did
    not take much pressure to accomplish this, so keep it light!

    73...and keep those soldering irons hot!

Subject: pc boards

I think that gary was refering to copies of pc artwork that have been scanned
, and could be ftped , then printed out on dyna-art paper or the tech-2000
film.  All you would have to do to get an artwork is ftp the appropriate
scanned artwork, then print it onto one of the above mentioned things.  Then
just dump it in the etch!  Gary and I have done this with a few boards, but
realize that not everybody has access to a scanner to scan the artwork
initially.  Also, Postscript is a great format for printing to a lasar
printer, but not a great one for manipulating in a easy format.  There isn't
much use to me to learn PC layout, but easy copying of artwork printed in
magazines and books is fun and can be done.  Having a ftp-able site with
various artworks available would be great.  Also... Please note that to
use the iron on process, it would be best to store mirror images of the
artwork.   It would be nice for instance if the ARRl had a ftp site that
I could anon log into that I could download mirror imaged copper artwork.
I could have pc boards that evening!

I'd like to carry my 20 meter QRP rig with me on business trips but
can only expect to operate it from within the hotel room, early in the
morning or at night.

I'd like to find an antenna that:

1) stows in a compact package and is light,

2) doesn't require a tuner,

3) deploys within the room in a few minutes, and

4) gets out.

Of course, any of these requirements are negotiable.  For example, a
very small tuner might be acceptable.

Ideas?

What did Brad say ?

I think my fpted is anon without a scanner. My ftp-able site
is filled with dyna-art paper.  I do know what tech-2000

i think my brain is too old for this stuff.... Hi

Subject: ORH Sprint & Voltage


Last night I finished my 40m OHR Sprint.  Given everything in the documentation
says its a 12v radio I powered it up using a camcorder battery (12.2v).
Everything aligned/tuned just fine, except for 3 problems:

    -  anything more than about 1/8 of full volume and there was a loud
           feedback like howl in the headphones.

        -  xmit output was at very best about 1.2 watts.

    -  receiver sensitivity seemed low.


I was watching the battery voltage with a DVM the whole time and it held
at 12+ volts.

I then used a 13.8v power supply I had.  Except for some expected hum the above
problems were gone.

Do I likely have a problem with my radio, or is the Sprint really not a 12v
radio?


Thanks,
Scott

Subject: Hotel Antennas


Randy, AA2U had a nice hotel antenna at Dayton.  We worked
stations in the Pacific on it.
Ask him for details....He is on internet.

Also we used to hang a 40m delta loop from the 11 floor balcony
at Dayton.... We also found a way to get up on the roof
and secretely put antennas there.  The delta loop could
be deployed in under an hour with 4 people working on it.

A lot of hotels have sealed rooms and no balconies.
I thought of bringing a small drill and making a tiny hole
to push a wire out through, under the window.

In Dublin IR, I found a way to get up on the roof of a hotel,
put up a dipole (I was unsophisticated in those days)
but thought I was going to be shot when the militia came
running through the hotel.

I recommend a Super Tee Tuner and 2 lengths of wire.
1 for the antenna and 1 for a counterpoise.  You may
be able to match the antenna by tuning for maximum
receiver noise, and have it work well.

The tuner is hi-Q and very sharp.   Experiment.

For versatility,
The single endfed wire antenna is probably the most
flexible, compact, quickest to erect, antenna for varying
and unknown situations,  and this tuner, which can be
built very tiny has low loss and a high matching capability.
The age old caveats still apply however, The higher, in the
clear, the better.
A horizontal wire is better for local, and a vertical
wire is better for long distance.

An antenna always works better if:
A piece of it comes from a previous antenna.
It is erected during a hurricane or snowstorm.
An old copper toilet tank float is put at the
    top of the antenna.


Otherwise,  Good luck

Ok, I admit, I wasn't very clear (at all).

lets go thru this one step at a time.

1. you see a project in 73 magazine you want to build

2. you need a board

3. you buy the board.... not!!!!

4. You ftp to some workstation on the network, and down load the artwork,

5. You then print the artwork onto a dyna-art paper or Tech-200 film with
    a laser printer, throw it in the etch, and you are done.

That's the final goal anyway, that Gary was eluding to.

The assumption is that you have access to a laser printer, (or good copier)
you have access to the network, other than mail. ie. ftp.
Also the other assumption is that the artwork is a mirror image! This may not
be obvious but it's true.

Subject:  Portable Antenna for Motel Room
Message-Id:  <[e-mail]>

I have used a 20m dipole combined with a telescoping mast made out of PVC
pipe and hose clamps with great success in various motels. I fed this
antenna with 300ohm twinlead but coax would work if 20m is your interest.
The mast was made of seven or eight sections of PVC pipe which was cut
and slotted like aluminum beam elements are. The sections could then be
joined together with hose clamps. A small C-clamp and wood block to retain
the end of the mast were employed for mounting to whatever railing or
wall that was conveniently located. All sections were sized such that
they fit easily inside my suitcase when disassembled. Since they telescope
inside each other, three sections only results in one pole in your
suitcase. The antenna was set up as a vertical dipole from balconies at
hotels in Israel and at Dayton. The lower half of the antenna was allowed
to dangle from the end of the mast which was protruding out from the
balcony like a flagpole. The upper half was strung vertically as far as
possible and the remainder was then routed in whatever direction was
convenient. With this antenna from Israel over 500 QSO's were made including
2 way QRP QSO's with the USA and Japan. The rig used was an Argonaut 509.
At Dayton this antenna with the same rig worked 13 countries including
several QSO's with KH3 as all the interested QRPers in the suite took
turns working the KH3 pileup. For this antenna to work well one should
request a room on a high floor when checking in. The antenna packs
easily as 33ft of wire is small and not much length of feed line is
required for this application.

I have been asked the question, why bother with making circuit boards?

Especially when FAR is cheap etc.

Here is a good example... The Color Burst Tx , Well I found the artwork,

and I had been so inclined I could have been on the air with my Color Burst
transmitter by now... Hows that?  For us impatient, and cheap folks , or
those people that haven't had the experience of pc board making it might
be worth it to say I even made the board... Now I'm getting in deep...

i'm getting good responses.  the project was a go from the start.

forgot to add argonaut 509 to the list.  there are some more coming.

the cost may go to $10 and that doesn't seem to bother anybody.
all you guys and girls making the big bucks?  sounds like it.

of course, this project is to help everybody in this group and it
is not for me to make any money.  once i get it together, it's not
taking that much of my time and it's fun.  just remember, i got an
80 hr a week job like everybody else, a yard, a wife, and all that
other stuff that comes with the territory.

someone else is working on the schematic capture and pc board stuff
and i think that's a great project also.  all this brain power in
one place.  it's great.

hope everybody is ready for field day.  it's getting closer and
closer......

keep the signals clean and strong and don't drift too far away.
operators are standing by.  don't send money yet.  i ain't ready.

Subject: Homebrew PC Boards

Hello All -

   I have purchased pc boards from FAR Circuits, and have
been very impressed with their quality and service for the
money.  After seeing the boards Brad (WB8YGG) had built, I
decided to try it myself.  So far, I have etched 10 circuit
boards from The QRP Notebook and QRP Classics.  To do so,
I used a flatbed scanner, a macintosh with adobe photoshop,
and a good laser printer.  Good boards would have been hard
for me to build without the above toys... luckily the my
place of employment has these things. [Note: you can alternately
use a paper copier and overhead material in place of the scanner
and printer.  If high-resolution scanned images of pc artwork
were kept at a central site (ARRL HQ?), we could simply use
ftp (file transfer protocol) over the Internet, and the scanning
step could be skipped.]

   The process starts with scanning the pc artwork from a
paper copy.  After scanning, the image must be mirrored
(flipped).  The image is then printed onto a special paper
(made by DynaArt).  The toner serves as an etch resist.
The paper is cut out to board size, then the image is ironed
onto the pc board.  The board/paper is then put into a
container of water, and after a few minutes, the paper floats
away, leaving the toner on the board.  The board is now
placed into the etching solution for 20-40 minutes.  You now
have an etched pc board.  Just drill the holes and you are
ready to populate the board with components.

   Since the DynaArt paper is expensive ($3/8.5"x11" sheet), it
is desireable to put as many pieces of artwork on the page
as will fit, as opposed to just printing one piece of artwork on
the entire page of paper.  This is where it is handy to have a
program like photoshop, which will allow easy manipulation of
images.  This is the main reason that I ended up making 10
boards, all at one time.

   This has been yet another aspect of QRP which has enhanced
my enjoyment of the hobby... making my own boards!  Will I
continue to buy boards from FAR and others?  Surely.  But I
won't hesitate to make my own, either.

   Another thing to consider is that FAR doesn't make boards
for everyone's projects; consider the KK7B single-signal direct
conversion RX-TX projects as an example.  The two board set,
available from Applied Radio Research, is $30.  I ordered them a
few months ago and still haven't received them!

72/73 and happy pc board homebrewing.  Anyone who would like
specifics of the above may contact me directly via email.

filter for every band condition at the turn of a knob. No need to
buy expensive accessory filters.

POWERFUL: 50 watts output is enough power to work the world, even
for a new ham. And power to spare for the skilled amateur. Runs
directly off 12 volts, even the cigarette lighter in your car for
easy installation.

SMART: TEN-TEC's exclusive "FLS" frequency lock system keeps VFO
virtually drift free regardless of temperature variations. THE
"RISC" microprocessor running at 5 MIPS also manages the large
digital display and built-in iambic keyer.

LOW PRICE: At $495, its closest competition is nearly twice the
price. No other rig offers so much performance at so low a price.

SCOUT is "back to basics" and redefines value for the active
amateur yearning for a second rig or the new ham searching for an
affordable way to experience the world of HF communications.

The note I posted (I got it off INFO-HAMS -- I forgot to mention that).

In previous posts it had been said that the band modules cost $225
each, but here it says $25. THis is much more reasonable!

I note that for an all band rig (160 thru 10) we have 9 bands @
$25/band gives $225 + $500 for the all band version. Perhaps thats
where the $225 figure came from.

I also note that it uses a PTO rather than a PLL -- old reliable and
low phase noise. Anyone know anything more about its front end design?

Hello All:

On a lark, I ordered the little Spider (from Jan 73) and got it in less
than a week.  Pretty good compared to Campbell, who is making a lot of
us wait for our R2 T2 boards.

Anyway, I had a spare hour around my research time so I wound the toroids
and stuck the iron on....put it together in no time.  Contrary to my other
experiences, all the parts were there and the radio worked fine first
try.

My wife laughed at it, all alligator clipped to my antenna and key (and
crystal clipped on, too), and asked if it would really work.  I heard
some guy signing off from a QSO, so....I called him.  He came back
with 579 report and we went on for about an hour at midnight on 7038.
Put a little thrill back into my life, there.  Simple and fun.

Anyway, I have one problem that someone may understand.  I bought the
10K audio taper pot for the RIT and it just isn't right.  When I put
my hands on the RIT wires I get just the right amount of resistance to
move a Khz or so, so it seems that the circuit wants to see about 200K
to 500K ohms or something, NOT 10K (it just goes off frequency and stays
there).  I suspect I can get a 100K audio taper pot and put a 100K
resistor in line and fiddle with that, but, anyone with a Spider see
this happen?  I have checked the parts carefully and didn't mix up any
resistors, although some of the transistors are substitutes (but used
per the manual.)  No big deal, though.  Just wondering.

So, I heartily recommend the little thing for anyone wanting to spend
$30 or so on a single board transceiver for a little fun.  Now I plan
to put it into a little box with battery pack and antenna tuner built
in.  My wife promises to get her General in the next two months - and
I will try to keep in touch with her via CW when I go on my long
camping expedition in the Rockies.  Simple, silly....but big thrill
to me still.  This radio stuff is just magic.

[Hope you don't mind me posting the reply back to the QRP list. I think
my comments have general appeal. Your message is included for context.]

That's all the info I have. I haven't even seen one yet! The message
even includes the garbled characters as it was received.

In fact your questions are ones I'd like to see the answers to. I think
some folks in the group (those that went to Dayton) may have seen the
rig already.

Regarding 6m -- I think thats a fine idea too. VHF weak signal is great
fun but it would need the finals to be cable of using that extra octave
above 30Mhz. This would have to be thought of from the start so you
don't design limits into the high frequency end of the PA.

Another point this seems to be a single conversion rig with a 6.1Mhz IF
(this has a lot in common with the older Argonaut -- like my aging
505!) so there may not be enough image rejection for a 6m band. All the
japaense rigs up convert to a 70Mhz first IF to kill image problems.
This is just speculation -- if this was a high first IF rig I would
have suspect they would have said.

BTW if the modules cost $25 I think pretty much all they could contain
is front end filters for the RX, LPF for the TX and a crystal hetrodyne
oscillator. This would imply plugging in the module for the band you
wanted to work on and removing all those funky bandswitch problems.
Just speculation, but this method would keep the cost down. Its a
interesting idea for homebrew rigs even if they haven't done it this way!

I expect we will hear more of it in the future -- keep watching QST. No
ads for it in the July issue which arrive here yesterday.

Please let me and the group in on anything you find out.

Kevin,

Hello from Delaware........I was reading the article you posted regarding
the "Scout" from Ten-Tec. I had a few questions regarding this rig I hope
you can answer;

a) How many bands does this rig cover? (ie. is it a monoband rig with plug-
in modules, or multi-band transceiver but limited to the number of modules
that you install (like most ham gear))

b) Does the rig come with any modules installed at all? (ie. installed with
40 meters, or your choice of band?)

I know the price of these modules seem to be cheap, but again was wondering
about it, since it seems like a ideal rig for mobile use. Also, will Ten Tec
offer a 6 meter module? I've been looking for 6 meter gear here lately, and
I'll tell you, it's scarce as hen's teeth to find anything used or anything
reasonably priced (less than ~ $700). That would be a killer rig for the op's
getting interested in 6 meters and VHF operation, and he/she could customize
the rig to their particular interests/needs. Maybe I'll have to call Ten Tec
and suggest that they look at a 6 meter module, for I'm sure that it'd blow
the Japanese competition away if they came out with a 6 meter SSB/CW rig for
less than $600. I know I'd be right up there to buy one myself!!

Thanks for the info on the rig,

73,

Joe KI3B

| LOW PRICE: At $495, its closest competition is nearly twice the
| price. No other rig offers so much performance at so low a price.

Let's compare apples to apples.  To add 8 more bands to get full ham band
coverage (not even general coverage rx) you must add $200 to the above
mentioned price.... not to mention the space they consume... looks like 8
more modules would take the same pannel space as the scout itself... I
don't know how deep the modules are so can't comment on the actual volume.

Oops, 10 meters only goes up to 29 MHz so don't listen to the FM guys (you
can't anyway... no fm mode) and don't listen to the AM guys up there
either or the RS satelites.... but this is back to basics.

Only 1 sideband per band... is that right?

Optional noide blanker for how much?

Is the microphone really an optional acce$$ory as the spec sheet implies?

For the money, I suppose I could find a $700 (ok, $695) radio that has more
features, twice the output power (oops this is the qrp list) available,
and doesn't come appart in 10 parts when I want to carry the whole thing.

I am sure the scout has it's place... Maybe for the guy who only opperates
one or two bands.  Yea, the thing can fit in your briefcase but what about
the battery or other power supply?  It requires 600 ma to receive,
remember.

I have heard alot of hype about the scout but let's compare apples to
apples.

Subject: My Sprint Voltage problems


I earlier told about my OHR Sprint problems running from a 12v camcorder
battery pack causing a problem and everything being ok when on a 13.8
volt power supply.

Well, I guess its the camcorder battery pack for some reason.  While
it measured 12+ volts under load from the Sprint it still caused the problems.

At Dick's (of OHR) suggestion I tried the car battery last night (12.2volts)
and the Sprint worked just fine!  I tried the camcorder battery again... same
problem, yet I could put it right in the camera and it worked fine there???

In any event, today I got got a sealed 12v battery (lead calcium) and that
works ok too. So the OHR SCAF and Sprint will all run from that.

Dick also passed on two changes to make to the Sprint:


    1.  Change R48 from 51K to 39K ohms.  This reduces the audio level
        and so you can use the full range of the AF gain control more
        easily.

        The Sprint kits are now shipping with this change.  I made the
        change on mine and it works nicely.


    2.  The is an error in the etch, however Dick says it does not
        appear to cause any problems.

        As you are looking from the front of the PC board, the LEFT
        lead of R7 (a junction with several other components) should
        go to the nearest ground.  Dick suggested taking a 1 inch or so
        piece of wire to the nearest ground point (look just on the
        right side of R7.)

        I have not yet made this change... hopefully tonight.


The watt meter, SCAF and 40m Sprint are my first OHR kits.  I'm a happy
camper.... they all assembled easily, the quality is great, the service is
great and they work VERY nicely and I'm looking forward to continued
fun with them... and to maybe getting an OHR dual bander (Explorer ???)
when its available.

Well, Brad, I put my Spider on 40 (for now, easy to change) and I have
xtals for 7040 (reads out at 7038) and 7110.  The Smart Tone works just
fine...if the xtal is pulled or the antenna gets loose (or goes haywire)
the tone changes a lot.  I suspect it will take some getting used to,
and that I may be able to diagnose other things with it as time goes
on.

I have been on the air with it 4 times now, my best DX is MI last night
with 579.  QSO for about an hour with W9IS - who went to High School with
Herb Johnson (of Atlas Radio) so we discussed Herb's new Atlas 310
and what a funny guy he is.  I also know him personally, so it was real
fun.  Also met N6KR, Wayne, who is sometimes here on the Internet with us,
there around 7038.  Was a real pleasure to meet up with him.

Altogether, I haven't had this much fun since my WN3JPG Novice days.  I
suspect it is that more skill goes back into the operation, since the
radio is so basic and simple.  The only modern day piece I use right now
is the Autek QF-1A on the output.  I used it a couple of times to narrow
the bandpass, and it is a real help, though it is no problem to copy without
the filter - but the concentration (exhaustion) factor goes up a lot.

So .... my 440S sits unused ... along with my other stuff, while I have
a real ball with this little naked board sitting on my table clipped to
power and antenna.

Subject: Crystal Sources

I sent this out earlier, but I don't think it made for some reason.  If you get
two copies, I apologize for the bandwidth.  Please use low temperature flames
:-).

I am thinking about buying a Spider, but I have no crystals.  The ones I had
when I was a Novice more years ago than I care to think about probably went
the same place as all those old baseball cards I had as a kid (but that's
another story!).  So, I need to find out what the recommended sources of
crystals are these days.  You can respond to my e-mail address, and I will
publish a summary when the volume drops to a trickle.

Thanks and 72, de Mike KT5H     [e-mail]

Help,

I just purchased a bunch of Nicads (surplus) in battery packs.  What
is the quick way to determine if the batteries are good?

ok gang, a day to go before the big one.

i'll be at K5MW/5 in NTX.  working for the Dinasour Valley DX Society.

in fact, we'll be near the Dinasour tracks and bones, thus i guess
the name for the group.  this is my first year to work with these
guys.  Al is an old friend from A&M, even though he's still a kid.

we'll try to stay around the qrp freqs after the test for just a bit
before taking down the five element 20 mtr beam and the 40mtr wire
yagi.  both will be pointed toward the NE USA.

day.  Jim, WA6GER, Wayne, N6KR, and I will be going south to the Zuni Loop
field day site where we are going to take advantage of Richard Fisher's kind
invitation to join that group for field day.  Sunday evening I will file a
report to the group on our activities.  It should be exciting.  Fred Turpin,
Cam Hartford, Clark Turner, Richard Fisher and others will be there.  This is
going to be the best field day ever for me.  Hopefully you will file a report
to us on your fd activities.  It will be interesting reading and fun to read
about the "adventures" of my fellow qrp addicts.  Send in a report Sunday or
Monday, and it should be fun reading.  Say hello if you work us.

Subject: NiCad Test


Gang,

Larry asked about nicads in battery packs.  what you do with them
depends upon so many factors.  let me just take a quick stab.

say they're in lots of 6 (for total of 7.5V or so).  charge them
at 1/10 of their current rating for about 12 hours.  if your charger
won't get this current, then one or more are reverse polarized or shorted
or.....  after the 12 hrs, measure the voltage across each cell and see
if they are all around 1.25 to 1.48 or so volts.  doesn't prove anything,
but it's a good sign.

in fact, at my desk i've been charging for AA nicads.  they are 1.25V
rated at 500mAh.  this means i charge them at 50ma for 12 hrs or so.
i use them in a sony walkman w10, which uses one.  been listening to
30 to 50wpm random calls, sections, and signal reports to get ready
for FD.  i hate random code groups, which is exactly what callsigns
are, but i digress....

i just this instance measured them after removing them from the charger
and they measured between 1.37 and 1.41V.

now, are you gonna use them in the pack, put them together to get 12V,
or use them individually?  put them to work and see how fast they lose
their voltage.  THE SECRET is don't let a bunch of nicads in series to
a load cause a bad cell to go to 0.0V and then start charging in the
reverse direction.  this is the thing that most kills cells.  the weakest
one will be charged in the reverse direction, thus measuring a negative
voltage.

you can take a larger battery, say 12V and use it to charge the battery
for 1/2 second or so to see if the voltage can be reversed.  don't and
i repeat don't do this for more than a second or so.  this is and can
be a dangerous procedure if the cell is shorted and heats up and builds
up gas pressure internally and .......

this will get you started and others will give their ideas also.
this is in the area of witchcraft and voodoo art.  you'll hear more
stories than you thought possible on the subject of nicads, their use
and abuse.

i've bought surplus packs for $0.25 to $0.50 per cell and had good
luck.  take care of them and they'll take care of you.  ;-)

Subject: MXM transceiver


Gang,

well, the new MXM rig, called a Simple Transceiver has been on solid
for days running off a 7AH 12V cell.  voltage dropped 0.85V total
after five days.  not bad.

the receiver is quieter than i previously mentioned, probably because
last sunday i had it on the 80 mtr long wire when there was a lot of
qrn in the neighborhood due to thunderboomers.

at night i can hear europe when the other receivers do not.  probably
couldn't work 'em now, but should work like magic next fall and winter.

i think that Bruce Williams, WA6IVC, will probably start taking orders
and stuff in 30 days or so.  as soon as i find out, i'll let everyone
know.  it will be a single bander for around $100 to $110, i guess.
doesn't include case, but the board is 4.25" wide x 3.25" deep.

not too crowded, with 7 of the small IF cans, 5 crystals, 5 8-pin ICs,
couple of transistors and final PA, and a couple of voltage regulators.

i'd guess about 65 resistors and maybe 40 or so bypass caps.  couple
of toroids for the output lowpass filter to be wound, but no problem.
if you gotta have the exact parts count, let me know and i'll do it
for real.   ;-)

i was able to put the board, variable cap, variable resistor for gain
control, PL-259, power, key (rca plug) and phone jack into one of
my cases very nicely.  i'll let you know how it receives on 40 meters
at night during the test this weekend.  that should be true test of
front end for any receiver.  the case is 6.5"w x 5.5"d x 2.5"h.
plenty of room to work.  i like some open spaces anyway.

after four weeks from hell and after sunday noon, i'll be about to
catch up.  thanks for your patience during this time.

see next posting on schematics and CW abbreviations.

Thanks Chuck,

I will take this home and digest it this weekend.  I guess I should
have said that I intend to disassemble the packs, find the good ones,
and assemble some new packs...

Now, I understand that I am looking for a test for each individual

Antenna's used were: 80 meters - 8JK Phased 2 element array up 80 ft.
                     40 meters - 4 Element Parasitic Delta Beam up 70 feet,
                                 all elements spaced 16 feet.
                     20 meters - 6 Shooter (6 phased half waves fed between
                                 elements) up 80 ft.
                     17 Meters - Lazy H up 60 ft.
                     15 Meters - G5RV at 70 ft.
                     10 Meters - Upper & outer at 50 feet.
                     2 meters  - 4 element quad
                     440       - 8 element quad

Several hundred contacts were made with the 40 meter beam working great after
midnite into the 4's & 5's.   20 meters was decent, with 15, 17 & 10 only
fair.  I had the greatest time of my life at a field day, will report our
score when I get it from Cam.  We operated 6A battery.  Beautiful site, great
weather, and I just hope the pictures that I took turn out ok.  Fred, Cam,
Bill, and the rest of the original group did an outstanding job of preparing.
Everything was perfect.  These guys really know how to do field day.

Rigs used were: Kenwood 660, Icom 735, Argo 509, 515, Wayne Burdick's Sierra
4 (hb 4band transceiver), Spider, HW-9 & Kenwood vhf and uhf rigs.   We used
N6GA's call in place of W6SKQ.

Boy am I tired.... But QRP FD was worth it.

On 20m,
I worked W3TS, N4BP, and heard N6GA, NO1E.

After FD,
I called CQ QRPI  from 1800 - 1805 but NIL.

On 20m,
The Argo 509 worked flawlessly with the 7 AH gell
cell holding up through the entire weekend.  The
corner fed Delta loop on 20m did well again.

KZ1L, with a tiny Mizhou 17 meter hand held SSB transciever
used an outbacker mobile antenna and made a number of SSB
contacts.  At sunset, he could work everything he heard.
I was impressed.

Dave, NN1G brought his 40m version of the 20m rig that
appeared in QQ, and it works as good as the original
20m rig.  I was impressed.

We had 9 camping out, and 2 visitors and ran 3A from WMA.

I regret not joining QRP-NE for FD.  I was on the air very little working
1E from home, but I wasn't feeling that well, and quite honestly, I was
bored doing it alone from home.  Saturday evening, I went over to the W1FY
group for a while, which was set up about 1/2 mile from my house.

From home, I heard W1FMR at least once, calling someone just before I did.
I wanted to jump in and try to work him, but that would have been impolite
:-).

I had a really wild wormhole into ORG section on 15m Sat afternoon, working
about 6 straight, hearing none of the other CA sections during that period.

I received and built my 2 Kent Key kits.

The first one I buildt was the Twin Paddle Morse Key kit. It
has a real heavy steel base. The main parts are machined
from brass bar. It has ball race bearing, solid silver
contacts and fine pitch screw threads with instrument knuled
heads that allow precision and individual adjustement on
each of the two contacts and springs.

The kit comes with the main pars assembled. It was fun to
put together.. and very easy. I suggest reading each
sentence of the instructions a few times before acting on
it. The directions are kinda backwards in my opininion.. EX:
it will tell you to mount a part with a certain size screw..
after you have put on the necessary washer and solder lug..
instead of telling you to put on the solder lug, washer and
then mounting the part.. no big deal.. still easy to put
together.

Really pretty key... the plastic paddles can be mounted
either with the pointed parts up or down.. I tried it both
ways and mounted them up.. fits the way I send perfectly.

The paddles work GREAT.. you can adjust them down to "breath
on them" level of sensitivity. I sold my Benchers
immediately after using them.  They can't fly apart like
Benchers.. the arms are solid.

Next I put together the Solid Brass Morse Key kit.. a BIG
straight key.. Had fun putting it together. This key is tied
with the nicest feeling straight keys I have ever used..
still also like my Merrick solid brass from Canada. The Kent
has all brass parts on a nicely finished piece of wood that
has weights that go inside it.

The Kent is really nicely weighted...precision adjustable..
haven't had time to try every possible adjustment yet.. but
easily got it to the point of loving the feel. Has a big
knob with the flat underpiece..I am experimenting with a
different approach to sending with it...I think it is like
the old telegraph style.

A great key.. only thing I don't like is they should have
used a harder wood.. the wood can be indented with any
pressure.. not good for really using it environment.

I feel both keys were bargains.. don't remember exactly the
prices (sent them in with the order). I think the paddles
were around $65 and the straight key around $75 or visa
versa.

Hi,

A good while back I pulled some info about the  ZS6BKV
antenna from somewhere. I built one for Field Day.

This is a 5 band tunerless antenna which was developed using
computer modeling. It has a good SWR on 40, 20, 17, 12, and
part of 10 meteres. Mine also was resonant at the lower end
of 80 and worked fine on 15 meters.

It is 92 feet 2 inches of wire (split in half as a dipole)
with 40 ft of 450 ohm ladder-line as a matching section.
This is then directly connected to some 50 ohm coax.. I used
RG58/U. I then took about 5 extra feet of coax and tightly
looped it around the end of the coax section nearest the 259
connector to keep out RF.

The club used a 440 with an autotuner and a bunch of QRP
kits I had built. The antenna was up at about 25 feet to
start, then I restrung it to about 40 feet.

The 440 easily tuned the antenna on all except 160 meters
(no big surprise here). The antenna worked GREAT. After I
restrung it at the 40 foot height.. seemed to be able to
work everyone first try with the 100 watts and had real good
success with the QRP rigs.

The antenna seemed to outperform the G5RVs that were strung
around at the other tents.. and has the advantage of working
a number of bands without a tuner

The Splitrock ARA Field Day went well. With our 2A setup, running QRP , we
worked several hundred contacts. We also had a Novice / Tech station, a
packet station and a VHF/UHF station going to keep the younger crowd
busy. Radios used were the Argonaut II, a Yaesu FT301S , an IC-730 and
various VHF rigs. We had 222MHZ but made no contacts there on FM. Antennas
were 2 tribanders, a 10m X beam, 40 and 80m dipoles and 2m + 222mhz
ground planes and J-poles. Antenna supports consisted of 20-30 ft
pushup masts, aluminum tower sections and military surplus 40 ft antenna
masts and a 20 ft crankup. Power was provided by several deep cycle
batteries and some really large military batteries. We logged all the
HF contacts using CT and 2 Zenith laptops. The rest was handled with
paper. I will still be typing in the data tonight. I estimate our 2A-
battery score at about 7000pts. but will have an exact number later.
     We had a number of thunderstorms on Sat. night and Sun. morning
that kept up off the air for a significant period of time. During one
of them I watched discharges from the PL-259 connector to ground. The
arcs showed up nicely in the dark. I did this from the safety of my
van. The ops at the Novice / Tech tent claimed they saw a purple glow
coming off their connector. Some sort of corona discharge maybe?
     I will post the final score later.

Gang,

worked with group from the above club.  my first outing for FD
in 8 years.  tried last year, but storm squashed that.

used IC-735 with 5 w out on 40 and 20 mtrs.  20 meter 5 element
trapless up 40 ft with rope rotator.  ;-)  40 meter three element
wire beam up 40 ft pointed NE from 50 miles SW of Ft Worth TX.

don't have the total but about 570 contacts or so for the test.

ops were K5MW (call used), WA5MWD, AA5SL, KD5EZ, WA5ZGC, AA5WH,
AA5UA, AA5TZ, and K5FO.

first time for me to use CT on laptop.  works great.  now i have
to go and figure out how to do them same at home.  ;-)

i've already seen reports of bad condx, but didn't seem too bad.
didn't try 15 or 10 although i listened on 10 driving to the site.
thought it would be open, but i guess not.  saw some note about
possible solar flare.  may have happened.

the one miracle was the weather.  fantastic!  no rain no wind
and temps around 70 at nite and 90 during the day (degrees F).

ohhhh.  CLASS 1A.  how did the Panama City FL group do?

ooops.  forgot to mention.  got on 14.060 after the test.  worked
K9RS on first cq.  he told me i had terrible chirp, this due to low
battery voltage, so i went qrt.  i did try guys.

we had one change on the battery during the test.  probably why
we had a loss in qso count.  we had period where we were not working
everything we heard and found out it was the battery down to 11V.
Icom just doesn't like it.

Hi Y'all,

  Well, not being into drinking beer and even less into contesting,
(IMNSHO the bane of the amateur radio service) I got involved this
year anyway :-).  We had nothing to prove since the entire station
here runs off 12V and the computers off a UPS full time - necessary
since we are involved in disaster services anyway - we *are* ready.

  What sparked this off was "who *can* I talk to ?".  The results were
interesting !  From 270440Z through 271132Z I managed to work 30
stations.  Not impressive I am sure, but interesting and actually fun
(NO, I still think there is too much of this as a normal course of
events).  Almost all of it being on 40 meters, all being "QRP" (formal
definition: 5 Watts) and all being done in CW (a mode that I have come
to like more over time, especially having the CMOS Super keyer and the
Kent key!).  Next year I hope to have a keyer with more capacity
(could be done if you could get source code for the thing).

The antenna is a dipole cut for 4.5MHz up about 15' or so and bent (to
fit :) one leg oriented E/W and the other SE/NW.  Radio is a Yaesu
FT-747GX.  No, just because it will do it, I *do not* "turn up the
wick", just because I can - a silly thing to do, IMHO only for the
integrity impaired :-).  All run off battery and I even un-programmed
the charger not to come on that night.  Class 1E IL.  (The batteries
are charged at night here as the electric rates start to approach
rational during that time).

It *was* a zoo.  The CW filter in the rig was practically useless and
the external audio filter (down to 80 Hz) was not much help either in
most cases there were as many as 5 stations (+?) within that passband.
Occasionally there were spots that were a bit cleared (only maybe two
stations in the passband).  If I could have worked everyone I heard,
it would have been a MUCH higher number than 30 contacts.  Best
coverage was to the northeast and southeast with reasonable coverage t
to the east and south (lots 1,2,3,4 and a few 5s and 0s, no 6s worked
(a few heard) and one difficult 7 and one VE3, one 8 (20 meters) and
no 9s worked, but one heard).  DX consisted of 2 Virgin Island
stations which were the ONLY stations on the band when I went slumming
on 20 meters about 0900Z.  With the solar conditions, I wasn't too
surprised at the lack of stations on 80 and 160.  The times I was
operating (local night time) precluded anything much above 40 Meters.

The late start I am sure didn't help either.  We had *nasty* weather
(so whats new in ILLinois :) that kept me on the weather nets until
just before I started on 40 Meters (three local tornadoes down ("minor
damage") several wall clouds that (thankfully) never formed and
several from other areas "down and headed your way".  After that
"Field day" was a yawn <grin>.  IF nothing else the storm lowered the
temperature so one could breathe.

The results were interesting.  I would have thought that the "best
coverage" would have been North/South and NW/SE  It turns out (from
this experience anyway) that "best coverage" from this antenna is to
the NE/SE, practically nothing N/S.  Interesting.  Best part was getting
some experience in CW operations.  My opinion about it being an abomnible
mode for communications still stands, but there are ways to improve the
throughput (of course a "contest" is about the most limited
communications I could imagine "de wv9k 1e il 5nn tu qrz", wow.).  I
did cheat and use the PK-232 down at the low end of the band where the
big boys were zooming along at 35+ WPM (I can't write what I hear fast
enough at that speed and haven't done enough of it to really hear
words, sigh...  More practice and getting more relaxed will probably
make it easier.  Since I am not a typist (I took engineering drawing
in high school rather than typing ( I was (am :) a real rebel in those
days :-) so that isn't too helpful, sigh...

I finally decided to go fall over about 0700 local (CDT).  Slept until
noon while my husband played around on 10M.  He had his best luck into
5 land with that !  He also fixed and "anniversary dinner" consisting
of steak and lobster, fresh corn (one of the few advantages of living
here) and other yummie fare.  Yes, it was a good field day <grin>.

The local QRP group did not fare quite as well out there in the storm.
Lotsa lightning and some bright folks who shut it down and went away
until after the airborne fireworks display ended.  That much rain has
to make for a decent ground :-).  I have no idea at this time what the
NEIQS did score wise, but I'll post it when I find out.  As for my
score, don't know and really don't care.

Next year I hope to have a radio with better filtering and I want to
see what I can do with pactor QRP.  If the bands are in better shape,
I am sure that will help as well.

Earlier in the day, around the start of things, I did look around 6
Meters, 2 Meters and 70 CM (all ssb).  Dead as a rock.  I did hear ONE
station on 2M.  Since he was running a very high power station, I
didn't talk to him (I do not support pollution :) and after getting the
s-meter needle unwrapped from the upper peg, I shut the rig off.  I
had *really* hoped that VHF/UHF would have been more active.  I didn't
even try packet (2M FM) as the cable tv system in this town leaks so badly
that the "packet area" is simply unusable (but it saves the money one
would spend on cable to watch TV <grin>, if one watched tv...).

All in all an interesting experience.  Not much as far as a real
emergency test (with a year to plan for it ? - call another one next
weekend and see who turns out :).  Also from looking at the rules
(briefly), it looks like a contest with even more involved rules than
most of them - I'll leave that to the "blood thirsty" contesters and
their lawyers <grin>.  The point is that it can still be fun and you
can still learn something from it all.  I suppose that if you can
operate reasonably effectively under that sort of adverse (QRM/QRN)
conditions, then we still might be able to do what the war department
wants us to accomplish.

I hope that everyone else participating had as much fun with it as we
did.

Take care es 72, Vikki.

Gang,
We are putting together the QRP-NE Newsletter.

I will pass along any FD war stories you may have
to the editor.

The modified HW-9, with the KB1MJ filter added,
did well 99% of the time, even though the 40m QRM
was fierce, no overload.   It is very selective.
N1CUU and W1FMR are pleased.

Now, there are a few other HW-9 problems.....
that we will save for another day...

I have an HW-99 Novice rig. (50 watt ~ version of HW-9).
W/built in Power Supply, 80, 40, 15, 10m cw,
it works great.  Anyone seen any mods for that rig ?

Low Battery Voltage ?

Radio Shack sells an analog 15 volt DC panel meter.
It consists of a sensitive meter with a series
resistor.   Leave it connected to the FD battery
terminals using a couple of RS clip leads.

I used it to monitor gell cell voltage for the Argo 509.


Also,
QST had a neat little expanded scale voltmeter project,
 perfect for monitoring 12 v. batteries a couple of
issues ago.   Maybe under Tech Correspondence.


The Argo 509 voltage dropped from 13.8 to 13.4 v  over
the entire period.    We used the speaker, which draws
more current, er.... uses more power than phones do.


NOTE !!!
Be sure to put an in-line fuse inside your HW-8
or HW-9, between the on-off switch and the power
connector. And tape spare fuses inside the cover.

A friend learned the hard way that when the battery
gets accidently reversed, all expensive, and hard to
get devices sizzle  and smoke.
On the positive side though, they only smoke for a instant.


With the Argo 509 (it is fused), the small battery voltage
dropped from 13.8 to 13.4 v  over the entire operating period.
And we used the speaker, which uses more power than phones do.

The only Problem with an ftp site for mirror imaged artwork is

1. What format?

2. Is it legal?  Artwork from 73, QST etc Scanned then put on the net?
I hope it is, but it's something I don't know the answer to, I guess that's why
I thought that the ARRL holding the ftp site would be good, then at least we
could get a part of the artworks out there without legal details.

3.  If we can do it, I'll certainly scan a few here or there, to fill the

good suggestions and ideas Jim, W1FMR.  battery was used for

was not my ic735 so i don't know what the current drain was with
speaker and all.  the bird wattmeter showed 5W out into the beam
on 20 and the wire beam on 40.  guess lot's of overhead in the
rig.  also may have been the battery, as it was used for a trailer

Harry,

The HW-9 xtal filter modification kit includes the filter
and an amplifier transistor,  and all other parts and
directions needed to install it, for  $26.

The Kenwood filter may be better, but I think this filter
is adequate and less expensive.  I would not want the
tuning to be any sharper. Even now, SSB signals are not
copyable because of the narrow bandwidth.


  Paul Levesque, KB1MJ   is the kit supplier.
  He also includes directions for a simple anti-thump mod.
  These mods appeared in the QQ.

     Just finished typing in the last of the logs into the computer last
night. We made a total of 792 QSO's with 260 being on SSB or FM and the
remainder on CW. Our final score including bonus pts is 7320. This would
have placed us 4th in our 2A-battery category in last years FD.
     Going through the logs I noticed that our Technicians worked W1FMR
on 2m FM. We were running 5w to a 2m groundplane up 40 ft. Wonder what
Jim's bunch were running? Our QTH was a superb VHF location though being
on top of a 900ft ASL + hill with nothing higher to the east, north east
and south of us.

Subject: Field Day


Hello All -

   Since the reports are coming in about field day exploits,
thought I'd share our experiences with the group.

   Brad (WB8YGG/2) and myself (N2JGU) ran a field day operation
as N2JGU from about 9am til 3pm on Sunday only.  Equipment was as
follows:

   (1) - cubic incher on 80m, to be exact 3.718 MHz (homebrew
                by WB8YGG; built on pc prototyping board).

   (1) - sudden receiver on 80m (also homebrew by WB8YGG,
                utilizing homebrew pc boards!)

   (1) - professional weekender xcvr on 40m (actually called the
                ugly weekender, but Brad complained that the
                final product looked too commercial to be
                called "ugly") homebrew by N2JGU

   (1) - wire dipole antenna, cut for 80m and fed with 300 ohm
                twinlead.  With the aid of an antenna tuner,
                it tuned 80m and 40m quite nicely.

   We ended up with 17 contacts in all.  PA, NY, OH, VA, MI, NH, CT,
MD, IN, VE2, and VE3.  We operated with a 10AH battery, which easily
lasted the entire 6 hours.  This was our first attempt at fd with
QRP equipment, so we were happy with the results, given the last
minute arrangements to even get out and operate.  We'll be there
next year, hopefully sporting a couple more bands!


72 and cul.
Gary N2JGU

Can anyone recomend a source for an 80C31 and 81C55?  This are replacement
parts to lower the power consumpton of the AEA Morese Machine.

I had only found these in an 'EASYTECH' catalog, but that company appears to

I operated with N7TNI and new tech as co-ops from Fort Flagler State
Park, WA (on the Olympic Penisula -- the top left corner of the map for
the non-WA amongst you!) as the novice station, N7WIM on the site of
K7LED, the Mike and Key club of Seattle.

As usual 10m varied from weak signal locals to sounding like 20m. For
us the band was open at the start (11am to 1pm local), then it reopened
on Sat night (8pm to 11pm local), then the next morning (9am to 11am
local). Fooled a few people in CO with an S9 signal, and one ope in NH
was suprised to hear us (I was suprised to hear them!).

We ran 3 element 10m monobander at 30 foot (I got volunteered to climb
the tower -- a first for me) fed by a ic-725 running 100W. The station
was located on a bluff about 100 feet above the beach. This gives a 180
view (N to S) across seawater. Gives good low angle radiation :-).

From looking at the log sheets we got about 260 QSOs (we didn't dupe
check as we went along, but our memories caught a few!). Al SSB, no CW.
I expect we beat last years total of 230 Qs. With a little more effort
(and perhaps some more ops we could have hit 300 Qs.

I don't have logs with me (chairman has them) but I can remember
working the following states:

id, ca, az, nm, tx, ok, ks, mi, ms, nh,
ma, nj, ny, fl, ga, tn, ky, oh, nb, nd,
sd, mt, wy, ut, wi, hi, la, ar, pa, md,
wv, wa, nc, sc, in,  il, co

where was delaware and nevada!

ve2, ve3, ve7,

best DX (only DX!) was FG5.

I enjoyed it (even though I was laid low with a bad headache for Sat
afternoon).

Kevin asks about (older) Ten Tec PowerMites.

I have experience with the PM3A, the 40 / 20 meter 5 watt transceiver.
It had a Direct Conversion receiver, sensitive, but not selective.  There
was an optional passive audio filter sold for it, and it did a reasonable
job, but rang pretty badly.

The PM3A ran on 12 volts, of course, and had a meter for tuning up.  There
was a tuning procedure - not like most transistorized rigs that are ready
to go when you move frequency.  It was no real hassle, though.  The
tuning dial was very rough, no calibrator, so you have to watch band
edges.  The QSK worked very well, I recall being quite impressed - the
rig I had come from was a Heathkit HW-101 (semi break in keying).  I
suspect I did all this back in about 1972 or 73.  Got me into QRP ARCI
back then, hence my low number (BUT, QRP ARCI then stood for the principle
that we should all run under 100 watts input power, if I recall
correctly.........! I was QRPp at 5 watts.)

I ended up working a LOT of my time with the PM3A.  I really enjoyed it.
If my memory serves me well, it compares with the HW7 and HW8, as I
remember them, however, the PM3A can be had for less money at swap meets.
(It has fewer bands and is older).

Has anyone any comments on either the MFJ-9020 (which in the UK is priced at
UKP 200-00) and the MX-14S (UKP 289-00)?

The MFJ-9020 has only just appeared in the UK amateur radio press.

On the MX range only the 80m, 40m and 20m seem to be imported by anyone
here. Comments on which one is 'best' would be welcome.

About the TenTec Power Mites:
Haven't seen these around at any hamfests for quite some time; I guess the
last time I saw one was around the mid to late 80's-- and the condition wasn't
very good on the opne I did see.
I recall these were a bit of fun to work with: at the Rome (NY) ARC hamfest
one was used in an annual qrp contest at the event This radio was perhaps
the one which got my interest in amateur radio in the first place!
Perhaps Chuck can add the schematics to his recipe book of qrp schematics.
I'd like to see these included!

Agree with wa3jpg comments on power mite, tho my memory probably isn't too
good after all these years. My experiences with the unit were also around 1973
think 1974 to be exact. Don't recall the details of the tune up procedure
but it wasn't too difficult. There was a meter on the unit to assist in this.
The tuning dial was very crude and difficult to work near band edges-- that
I do recall clearly! It has been 20 years since that rig was out. We did have
alot of fun with it-- from Rome NY (home of the soon to be former Griffiss
AFB) the club contestants were working MI, OH, NE, ID-- think the winner
of that contest (each participant had 15 minutes to try to make the greatest
DX contact) won with a QSO to Nevada. Sensitive radio, but not too selective.
Great fun though!!

Jim, W1FMR asks about Index Labs QRP +.  I talked to Index just yesterday.
They have a production run of 100 units scheduled to be finished in late July.
About 70 units are committed.  For Field Day some of the folks took early
prototype rigs up in mountains and ran for about 20 hours on Gel-Cells, mostly
40 and 20 mtrs cw (ssb was hard...).  Largest problem seemed to be having the
rig dragged off the table when someone got tangled up in the coax --
definitely not a boatanchor!  Hope this helps...

QRO Gang

While prices of HW-8 and HW-7 have gone through
the roof, Power Mites have not (yet).

12,000 were manufactured and there should
be lot around.   I have a complete collection
PM-1 through PM-3A.

You would not be happy with the receiver
after using an  HW-8, but operation is similar
to a HW-7.

Mechanically it is not as rugged as an HW-7.
There were about 6 for sale at Dayton, and the
prices varied from $35 to about $75, depending
on condition.

They are fun to use, and take some getting used
to.  They draw hardly any current and a couple
of lantern cells should last for a summer of
operating.  Look around flea markets for
a pair of high impedance headphones or/and
an old 9V. battery powered MFJ audio filter
to go with them. That should provide you with
an entire "Period Classic QRP Station".  The
audio circuit was designed for high impedance.

Ten Tec still fixes them.  However, they are
probably the only rig around that can be trouble
shot with a copy of "Solid State Design", and
fixed with a volt/ohmmeter and regular soldering
iron.

The collectors are catching on fast with these rigs.

Happy Hunting......

Having used an HW7, -8, and -9, I thought it would be interesting to
imagine what Heath might have done as a successor to the -9.  What would
the specs be?  What would Heath have called it?  Should someone build it?

Another question, no less interesting, is what WOULD an "HW6" have been
like, had there been one?

Just imagine coming upon either of these rigs at your flea market of the
mind.  A fine price they would fetch, no doubt!

very cheap.  more machine work to install also somewhat of a disadvantage.

95% of the survey said they were for toggles and use them regularly.
the minature ones that OHR and others use are not out too far from

     If you're looking for a good expensive keyer, I
recommend the CMOS Super Keyer II (93 ARRL Handbook, pp 29-6
through 11). Kits are available from Idiom Press, Box 583
Deerfield, IL 60015, for $45 + $3 shipping. I'm not
connected to Idiom Press, but I've built their kit and
installed it permanently in my HW-9. The board is about 1.5
X 2.5 inches with the battery, 4 push-button switches and a
pot mounted off board. The push buttons control the memories
and some commands. Sending speed may be changed via the pot,
memory commands or the paddles. The keyer has numerous
commands that are input via the paddles and may be included
in memory messages. A very versatile keyer for little $$.
(The SA-5010 was $99 new.)

So send 'em you money -- this is a good deal and easy to build too!

I also wrote to Idiom Press. Asked what the status was. Recieved
a nice letter back in my sase in about a week.

They said that the price is $48.00 for US addresses or US $50.00
for overseas orders, postage paid. Payment in checks or money
orders and must be drawn against US banks. No credit cards.
US currency can be sent at the sender's risk.

I will be sending them some money soon. Would have posted sooner
but just got the computer back today.

Installed a CD Rom, sound card, more mem, etc..... Now if I can
just learn how to use it again......

Well, the SB-104 preceded even the HW-8. I had the
"pleasure" of constructing the SB-104 used as a demo
at the NYC Heathkit store (RIP). Quelle chien! But at
least it had a VFO, not a synthesizer.

If Ten-Tec relit the Argonaut 515 production line,
and added WARC bands, how much would you pay to own
one?

Recently I needed to make some little modules for one of our customers.
I needed to label the modules quickly and neatly so I used a sheet
of adhesive backed repro film.
I designed my label on the computer, then I feed the repro film through
the laser printer to print the label.
I then cut the label to size, peeled off the sticky back, and stuck it
to the module.
It looked better than I anticipated.
The repro film is translucent so the color of the module comes through.
You might want to spray the label with clear acrylic to make it last.

The repro film is made by

     Rayven, Inc.
     431 N. Griggs St.
     St Paul, MN 55104

I think we got this stuff from the local drafting supply store.
I have a hunch a full box would cost an arm and a leg.

I just found the stuff listed in a local office supply store catalog.
A box of 100 8.5" x 11" sheets is $65.00.

Our main goal was to have fun and fellowship, and we certainly
succeeded.  But we sure could have used additional operators.
I hope more can join us next year.

* Dave, NN1G brought his 40m version of the 20m rig that appeared in
  the QRP Quarterly for part of the weekend.

We had 11 participants, Frandy N1FJ, Barb NK1I, Art KY1K, Jim W1FMR
(used his call), Andy KZ1L, Carl N1CUU, Greg WA1JXR, Derek (son of 'JXR),
Dave NN1G, Tim KB1ARZ (Novice, son of Dave) and Mark NX1K.

For the second straight year, we set up at the Princeton, MA Light
Department's windmill farm on the West side of Mt Wachusett.  This
site, with its 8 windmills, produces about 7% of the electrical
power for the town of Princeton and is about 450 meters above sea
level.  The site provides a clear shot to the South and West and our
experience shows we get good reflections off the mountain behind us.

It was hot and windy on Saturday, with the windmills turning until
about midnight.  For the rest of the weekend, the air was still with
the exception of very heavy rain for about an hour early Sunday morning.

Fred Bonivita has been promoting this -- almost identical articles
appear in the NE QRP's journal "72" and the MI QRP's "T5W". And SPRAT
had an article aout it a couple of months ago.

This is a small no frills iambic keyer (mode A or B not specified --
does anyone know?). The pcb is smaller than a 9v battery at 1.5" by 2".
It has only one control for speed. The design is a voltage regulator
feeding an NE555 as clock generator clocking a custom PAL. The PAL
drives a small reed relay through a transistor, so I imagine it'll will
key anything with a low current line.

The kit is 16.50 pounds sterling. The PAL is availible for 5 pounds
sterling. They do have VISA and M/C now -- when I first read of this
kit in SPRAT they didn't have this. This removes all your hassles with
money conversions. When Fred ordered the kit it cost him just a little
over $25 (inc airmail postage) and the kit too 10days to arrive. He
built it in 1/2 hour and it worked first time. If you can get the 555
to oscilate then this kit can't really fail to work!

If you've been looking for a kit to ease you into construction but
haven't got around to it then this could be for you.

Ordering details:

Kirsta Computer Ltd.
35 Main St
Dunfermline
KY11 5ND
Scotland

Yes, GM-land!

KCL002 IC is #4.95
full kit is ##16.50
built and tested is #21.00
airmail postage is #1.00

You can get a flyer and order form frokm the above address, but I
figure a letter would would just as well.

Fred suggests putting it in an RF tight box -- presumable to keep the
digital rubbish and (and perhaps to keep the RF out -- dunno how
suscptible this is to stray RF).

I'm planning on ordering one.

Subject: Things that never were ?


Wayne, N6KR  discussed Heathkit rigs that never
were (seen ?).

Two years ago Heath was selling the last remnants
of their kit stuff at Dayton, and in the junk pile
 there was what looked like a prototype HW-7 or HW-8.
Amazing to see how close the rig looked mechanically to
the end product.  Somebody
probably bought it.

A sort of successor to the HW-9 may have been the HW-99.
I have one, and it works.  It has ample audio and selectivity
(the xtal filter works).   It has only 4 bands, 80, 40, 15, 10m
and is called a novice transceiver.
When I use it, it works great, but I feel that something
is missing (RIT, 20meters, S+/SWR meter).  It is too simple.
It does have a built in power supply and 50 watt PA.

If you are looking for a nice performing 4 band superhet cw
rig for that beach cottage or camp, I have seen these for
less than 1/4 the going price of an HW-9.

One thing that suprised me while trying to come up with modifications
to the HW-7 (I have a 7 and an 8, but still haven't managed to snag a 9
yet) was what an terrible design it was EVEN for the early 1970s. They
could have copied the Wes Haywards diode DBM direct conversion design
(published in 1965 QST?) and had vastly better receiver for no increase
in production costs -- perhaps even made it cheap. I think they went
for the fashionable (at the time) 40673 and CA3035 for no particularly
good reason. The TX is almost as bad -- with random offsets on each
band. Everytime I reread Ade Weiss' 1970s writings in the QRPp column
in CQ and in the Milliwatt I am constantly amazed what those folks did
with the HW-7 and the PowerMite rigs. Maybe it forced you to be a better op!

But this is all 20-20 hindsight. Very few people were thinking about RX
performance in the way we do today.

The HW-8 is far better, but why did they leave out an RIT -- didn't
they learn anything for the HW-7!

The HW-9 again was a big leap. Using DBMs and a superhet design in the
same size box as the 7 and 8 showed some genius but they still spoil
the ship for a ha'peth of tar -- a mediocre response and poorly matched
xtal filter. Unreliable injection levels in the product detector, poor
receiver muting, drift which varied from model to model. Take a look at
the HW Handbook or QQ or SPRAT for the various solutions to these
problems and others.

The HW-10:

* would be in the same size box ad the earlier models
* would have SSB but no speech processor
* would have a commerical 2.4kHz filter, but wouldn't have a narrow CW
filter (most would appear soon after to add this).
* would have a built in keyer as an option
* would have a similar RX design to the the HW-9
* would have a similar TX design to the TenTec QRP rigs (broadband
drivers and final)
* would have a single regular VFO (not PTO or PLL)
* would have been $400 or so
* would have moved to a two board design to filt more in the same space
* would have been bought by a few hard souls
* would still be sought after today :-)

I  just thought that I would let everyone know that there is a pbbs here in the
West Central NY area that specializes in QRP.  It's run by WB2QAP, and
you can connect to it via the CANDGA node.  Connect to WB2QAP-1 once on the

into.
P.S. are there any other QRP PBBSs ??

Well, response to my question, "How much would you pay
for an Argo 515 if Ten Tec resumed production" was
underwhelming. In fact, only that venerable stargazer
and QRP denizen, K5FO, even bothered to respond. Chuck
said he'd pay $700.

I'm quite surprised. Here we have tons of people joyfully
plunking down >$150 for single-band CW rigs with direct-
conversion receivers. Assuming 9 bands, you're talking
$1350, CW only! A smart manufacturer could certainly
produce a QRP CW/SSB rig for half that price.

Jim Fitton asks about Internet connections. Delphi
offers limited access at the moment. Via Delphi you
can read mailing lists like this one, but not Internet
newsgroups like rec.radio.amateur.flamefest.

You need a terminal/computer and a modem. In many parts
of the country the telephone call is local; if you live
in the boonies you may have to pay for the call.

Delphi offers two plans: One is $20 for 20 hours + $3/mo
for Internet access as noted above. The other plan is
cheaper and fewer hours.

If you can send email, you can request info from Delphi:
[e-mail].

I am neither a subscriber to nor an agent, affiliate or
employee of anything that even vaguely resembles Delphi.
I saw their ad and asked for more info. I'm waiting til
they get full access so I can see how much they charge
before I sign up.

You can also read mailing lists like this one through
MCI Mail, Compuserve, and, I believe, America OnLine.

If you can "telnet" from work, it's possible to access
Internet through some sites at universities, though
most of these sites really can't handle a great deal
of additional traffic.

I copied this postings from Internet's rec.radio.swap.
The SB-104A had selectable 1-watt output. If this radio
works as advertised, it would make a good foundation
for a QRP rig. It doesn't cover the WARC bands, but
considering that single-band rigs cost over $150, $250
for 5 bands SSB/CW + heat when you need it seems like
a good deal. I don't think this rig has RIT, but it
wouldn't be hard to add.

Subject: Permission to include articles

I just wanted to respond to the two who requested permission to include
articles posted to the QRP mailing list in their QRP club newsletters.

First of all, I have no problem if you do it, but I don't feel the
permission is mine to give.  While it is very nice for you to let everyone
know you are interested in doing this, I don't want you to assume that lack
of objection constitutes consent.

I don't know exactly what copyright law is on quasi-publications like this
mailing list, or Usenet news groups...it has been discussed often, but I
don't know of any case law.  I go under the assumption that the author of a
message or article is the copyright holder, and by submitting it to the
list or group, he or she has given permission for it to be published in
that forum.

However, I also go under the assumption that the author retains other
publication rights.  I know that it has been a hot topic in at least one
newsgroup which I frequent (rec.aviation): a certain national aviation
magazine included articles published in the newsgroup without permission,
and the authors were sometimes quite perturbed, even if credited...what you
write in one forum may not be what you would write for a different set of
people in a different medium.

So, if you want to pick up text published here, please contact the
author(s) individually to secure their permission for each thing you want
to publish.  As long as you do that, the "list management" has no
objection.  Sound OK?

Internet, my favorite subject.  Finally something I think I can
contribute on for this group.

There are many books at the bookstore that discribe all the
ins and outs of internet and email.  One book I found useful
is UNIX COMMUNICATIONS by the WAITE GROUP.  This one covers
mainly email, email addresses, and uucp.  I sure others can
recommend very good books on other aspects of internet, ftp,
telnet, gophers, etc.

But wait!  Once I have all this wonderful information where
do I go to get an account, you may ask.  This is the part that
amazed me.  Unless you have an email account from at a college,
or your employer has  provided you with an account, how do you
go about getting one?  For myself, I never new that anything
like internet even existed until one day I overheard a fellow
contract programmer mention he had an account with a particular
service provider (I won't advertise names here, no need to anyway).
Even though his account was more like prodigy, all menu driven, it
did have email access.  Later, by chance again, I found a company
that provides dialin accounts with access as a regular user, choice
of bourne shell, C shell, or Korn shell, and full access to internet
including email, news readers, ftp, telnet, uucp, etc.  I was
surprised that I had not seen any ads for these companies and that
only by accident I had found out about them.

Anyways, here's the point.  There is a site on the net that
maintains a list of all known service providers.  The list is
called NIXPUB.  You can get it by doing one of the following:

    To subscribe for regular updates send mail to
        [e-mail]

    To just get a current list send mail to
        [e-mail]
        in subject or body of message put
            send nixpub long
        or
            send nixpub short
        or
            send nixpub long short
        or even
            index nixpub

There are more ways to get the list.  They are explained on the list
itself.  But since I know everyone here at least has access to email
then I know the above will work fine.

The NIXPUB list contains a list of internet service providers, the
type of access they provide, and how much they charge if any.  There
are quite a few that provide email access at NO CHARGE.

Get your copy of NIXPUB today, and get all your friends connected
for free.

Didn;t see you previous message -- and I read all the QRP list messages.

About $150 is OK for a 505 -- I have one and paid that and am happy
with the value for money -- it had been well cared for and had be
recently realigned by  TenTec. I could see people paying up to $200 but
I don't think I'd go more than that -- heading to 509 country.

Well, response to my question, "How much would you pay
for an Argo 515 if Ten Tec resumed production" was
underwhelming. In fact, only that venerable stargazer
and QRP denizen, K5FO, even bothered to respond. Chuck
said he'd pay $700.

I'm quite surprised. Here we have tons of people joyfully
plunking down >$150 for single-band CW rigs with direct-
conversion receivers. Assuming 9 bands, you're talking
$1350, CW only! A smart manufacturer could certainly
produce a QRP CW/SSB rig for half that price.

I'm sure everyone here has deduced where I am employed. Yes,

publication.

There may be a problem with a commercial magazine reprinting
uncopyrighted newsletter articles without notice. It's
happened in the past. If anything I wrote here appeared in
a commercial ham magazine, the company's Usenet access
would be in jeopardy.

If you ask, I'll probably say yes and ask you to include

Howdy,

For all you home-brewers.

I stopped by "Surplus Stuff" in Milpitas on Saturday and they have a
sh*t-load of 2.5AH lead-acid batteries for sale for $4. These
batteries consist of 4 2V cells loosely hooked together but can be
re-packaged to 6V configurations quite easily.

Surplus Stuff is located on the corner of Milpitas Blvd. and Yosemite Dr.
in Milpitas.

service and have been a client for about two years.  You have to pick up
the long distance if you are not in their access areas.  By using it at
night I pay about $6/hr for access.  They have access in several CA towns
as well as Portland, Dallas, Seattle, and some other places.  You can get
info via [e-mail] or call 408-241-9760 with your modem and login as

Subject: HW-8 prices/caveats

Hello All,
    After reading the various debates concerning TenTec prices,
I'd thought I'd throw out an inquiry. I have an opportunity to
purchase an HW-8 for $125, and is available as a consignment item
at the local ham shop. It's been checked out and is claimed to
produce ~1.4 t 1.6 watts out on the various bands. No power supply
or manual are available with it. The notes accompanying the rig
indicate some sensitity problems on 20m (possibly alignment?) and
the switches/pots need to be cleaned. The bottom line: Is it worth
the asking price? Is the power output typical for an HW-8? Any other
caveats I should be aware of?

I know there are many experienced users waiting to share their
opinions, so I await with bated breath...

Bob,
$125 is a fair price for an HW-8 but finding a manual
could be a chore.
Low power output on some bands was due to faulty
toroid cores, and can be easily corrected.

A couple of lantern cells could power it for 6
months of casual operating.

Look inside at the soldering job (kit) and
make an offer ($100) ?

When you think about it, you get 4 bands of QRP
for $125.  That is $32/band.  Much cheaper than
any kit (except the Spider) and it has a VFO/

You can have fun adding  (in order of importance)
1. In-line fuse
2. SWR meter mod
3. S-meter mod
4. RIT


That sounds good to me.  I used an HW-7 for a
year before buying an HW-8, and used it for
2 years.   The 8 was a giant step up from the
HW-7.

An HW-8 is worth $50 at most. I bought my HW-9 two years
ago, with WARC bands and power supply for $150.

The owner of that HW-8 is a dreamer!

to bring them back also.  with the influx of new blood, there should
be a market there to entice one to bring them back.  in fact, i have

This is somewhat expensive I paid $90 for mine and I thought that was
steep but it was in good condition and worked OK. It will keep you busy
over the winter adding all those it need mods too it!

I'm looking for a dead HW-8 (to convert to WARC + top band). If anyone
comes across one please let me know! Beats moldering on the shelf someplace.

Finally, does it seem to everyone that QRP rigs are getting more scarce
and more pricey (especially compared to QRO rigs of a similar age). Any
ideas why? Is QRP really getting that popular? Are people collecting them?

Still looking for a WARCed HW-9 (electrical condition unimportant) too!

Cc: [e-mail]

The going rate for a HW-8 is more like $75 or 80 perhaps a little
higher. $150 would be good going for a HW-9 today. When rigs are in
demand then its what the market will stand ...

Hah !

Two years ago at a ham flea market, I paid $150 for
my HW-9 with P.S., WARC, speaker, and manuals.
That was 2 years ago before all these confounded QRP
clubs caught on.
The same rig is worth at least $250 today.

Last year an unmentioned (friend ?) picked up an HW-8
at the same ham fleamarket, in factory a box with P.S.
both mint at $20 for both.

But, have you ever won a lottery ticket  ?

I was envious until I won an Alinco duoband handheld doorprize
minutes later.

By the way, I have used the duobander exactly 3 times.
It sits gathering dust, but used the HW-9 hundreds of times.

Moral......  You can wait forever to get a bargain, or
              get what you want right now, without altering
              your lifestyle.
              Pay the going price, or less, and enjoy it now.

it's still in print.  someone might comment on this.

speaking of in print.  has anyone gotten any word to/from Ade Weiss
on his 'Joy of QRP' and 'History of QRP' to see if he is going
to bring them back also.  with the influx of new blood, there should
be a market there to entice one to bring them back.  in fact, i have
one and not the other and certainly would like to complete my collection.

Well, it looks like the market is driving up the
prices of used QRP gear. I would definitely say
the market is growing. Heath bagged it too soon!

Ham radio is growing at an amazing rate. We've
gained 100,000 new hams in the last couple of
years.

I think the demise of Heath had a salutory
effect on the kit business in the US, as many
others sprang up to meet the demand. No one is
making an 8-bander for $300, though.

I've recently started learning to fly sailplanes
(QRP flying). That sport is in trouble, I think,
because the only new sailplanes available come from
Europe and cost >$20k. The last American mfr bailed
out about 5 years ago, to concentrate on more
profitable segments of its business, just like
Heath. Like Heath, this company grew with and
contributed to the growth of its sport. Are
American companies getting _too_ greedy, to the
detriment of hobbies/sports? The new European
sailplanes are very high performance, and priced
to match, comparable to the Argonaut II. Most of
us would be happy with an HW-9 or a Schweizer 1-26,
but we have to take an Argonaut II or a Grob 102.
Wally, K2IHO (SK), my Elmer, told me to marry a
rich woman. Guess I should have listened to him!



I spoke with Ade Weiss on the phone a little
over a year ago. At that time, he had no
interest in reprinting or revising either of
his books. His phone number is available
from directory info for his _Callbook_ address,
if anyone wants to say "hi." I'm afraid some
political snafu with QRP-ARCI sent Ade off,
along with a divorce and, I hear, some
medical problems. I got this info secondhand,
so don't quote me.

As much as I enjoyed his writing, there's
certainly no lack of good reading material
for QRPers. Perhaps Adrian was like the
mythological guide, who could take us only
so far along the path. Now, it's up to us
to continue with the quest.

Subject: HW response

Hello All,

    Thanks for all of the responses about my HW-8 posting. Sounds like
I'll put on my bargaining hat and try to make a deal. The rig is clean
and has no obvious mechanical mods. It's worth a try to peek under the
hood. Right now, I'm straddling the fence on which rig to buy. I really
like the OHR Spirit, based on postings here and other things I've read.
But, the point is made that it's a single band rig... Although, I would
like to get a rig that's nearly ready to go without a lot of fuss. I've
other rigs for that purpose.

    One question still remains for me. What is the typical/best power
output from the rig, assuming the proper toroids, etc. are in place?
I gather from the responses that this is not a 5 watt output rig, but
something less.

Thanks again,

Bob N3MBY

These are "Gates Cyclone" lead acid cells.  When they're new, they're
the best deep-cycle small lead acid batteries around.  They retail
for about $6.50 each when they're new.

These batteries are used in the new "high-power" Vista-Lite VL420 and
VL430.  And they are an excellent choice for bike lighting, especially
if you are building a system that will be gather charge-on-the-run
with a generator or solar cell for recharging.

But here's the caveat:  The batteries have a limited shelf life, and
they seem to last about the same amount of time whether you use them
or not.  I'm trying to get documentation on how to read the date code
on them, but if they're over about 2 years old, don't waste your money.

From: Clark Savage Turner WA3JPG <[e-mail]>
Message-Id:  <[e-mail]>

Anyone know anything about the OMNI-D from Ten Tec, and its vintage?
Was it the big brother to the Triton IV line?  I understand that WARC
crystals were an option (installed in the radio I am inquiring about)
did it actually have band switch positions for WARC?

I understand that it had a notch filter, and that it had optional
crystal IF filters AND separate audio filters?  Anyone have a manual
for this radio?  I wonder about the CW-ability of this radio.  The
Triton IV was really nice for CW, and if this was an improvement,
it sounds really good to me.   Similarly - I am suspecting that the
QRP-ability of this radio is simple as it was on the Triton IV?  The
current drain on receive?

Any information would be greatly appreciated.

Message-Id:  <[e-mail]>

Howdy all:

The discussion about the desire for "successors" to the Argonaut series
in between the 515 and the Argonaut II has me thinking - could I revitalize
my 509 to put it up to my expectations?  The 509's are plentiful and still
reasonable (on occasion!).  What would I want for my 509?  I am mainly
a SSB operator, but have significant interests in CW also.

Improved selectivity for SSB - need 8 poles.
Crystal filter for CW, 400 HZ or so.
Built in keyer for CW operation.
Speech processor for SSB.
Better receiver AGC!
Better dial-string (ick) design - causes backlash and slow drift.
Improved bandswitch design....it is mechanically joined and loosens up - hard
to clean, this seems to cause some drift, too.

Well, this is a real wish list....I will certainly not do anything about the
bandswitch or the dialstring!  (Under threat of death from many local QRP'ers
- they will NOT tolerate me tearing the 509 up for my own selfish desires!)

The selectivity on SSB should be simple.  Get another 4 pole from Ten Tec
(or another source) and cascade it with the normal 4 pole filter in the rig.
I plan to do this next week.

A crystal filter for CW operation....now I must install a switch, and find
a good source.  I believe Ten Tec filters are being closed out by AES and
we might get a good CW 9 mhz filter for cheap.  I will look into this.

I have an old Waters Compreamp (anyone else remember these guys?) that I
can pull the board from and mount it inside the Argo without much trouble.

The keyer is a simple addition.  No problem there.

The AGC is something I don't know much about.  Anyone else ponder this
much?  Would be nice to tighten it up so that strong signals do not blow
me over.

Also, anyone else able to cure / slow the drift that occurs in the
Argonaut 509.  It is not bad, but would just like to get to it.  I have
a pal with his own 509, and it is stable as a rock.  I am jealous.

If I can remember correctly, the OMNI-D came out in the early 80's.
We bought one of these to replace our TS820S at VE1UNB, the club station
at University of New Brunswick. I can't remember if it did have WARC band
switch positions ... I think it did. As with all TEN-TEC rigs, CW is not
added in as an afterthought. This rig was beautiful on CW. If I could
find one in good condition I would buy it.

Subject: Problems w/ Argonauts


Regarding Drift

One problem with the 505 and 509 is that on bands other than 75/20M the
VFO gets doulbled or tripled in other to supply the correct injection freq-
uences to the mixer. Therefore drift doubles and/or triples too (this is also
why the dial scales from band to band don't track very well). On the 515,
TenTec changed to a premixing VFO for injection which is much better.

AGC Problem

Its just a poorly designed circuit (even their engineers will agree). The
audio derived voltage is used to reduce the supply voltage of the RF and or IF
amplifiers (which are MOSFets). Also having a RF amplifier in front of the
MC1496 mixer is poor. During 40M night, 20M open and most contests the Argo's
fall apart (poor DR, IMD etc.).

IF Selectivity

The 515 had an 8 pole optional filter available (stock was a 4 pole lattice
design). Be careful with putting in other units (center frequency is not ex-
actly 9.000000MHz and Z matching).

I spoke to Paula Franke... Pres of ARCI, last week.
She is having work and medical problems, however
the QRP Quarterly has gone to the printers.

I have not rec. the OK-QRP, or the G-QRP newsletters.

The QRP-NE newsletter is being worked on as we speak.

July and August is vacation time and difficult to keep
focused on the hobby.....

Kevin,
To answer your question on how to join the OK-QRP club,
I dont know how much a membership in the OK-QRP club cost
as I exchange ARCI memberships with OK1DZD.

From the newsletter, which has some english translation,
membership and general correspondance go to;

OK1CZ, Petr Doudera
U1.baterie 1
16200 Praha 6
Czech Republic

I met Petr at Dayton this year, and he is a great guy.
 Jim, KR1S hosted him for a few days in CT.

I will send a copy of this correspondence to KR1S, in
case he knows how much a subscription cost and how to
send funds.

Publishing correspondence from this mail list without authorization should
not be done. In addition the the professional standards of conduct noted by
Jim, KR1S, I think this practice would inhibit on-going participation.

Contributions are often made with some context (i.e. comments to a specific
question or discussion). Without this thread, a specific posting may not be
understood, complete or accurate.

Contributions may be based on material already submitted for publication,
contain proprietary information etc., so we should not put our contributors
in an embarrassing situation.

A contributor may not wish (for whatever reason) want to support a particular

There is a new Usenet newsgroup on homebrewing.  No one has set up a
gatewaying mailing list, as far as I know, so receiving the articles by

I do not have the time to administer such a thing, at least for the near

and

20 Meter Superhet Transceiver  $49.95  from Jan 1993 QRP Quarterly.

the last item is the one i sent my check off for.  i was looking at
the article last night and it looks like it outta work great.  reminds
me in some ways of the MXM xcvr now in progress.

oops.  QRP crystals  14060, 3560, 7040, 10106 are $5 each.

shipping and handling $3.75 per order.  make check payable to
Danny Stevig.

Jeff Jones, AB6MB, posted the info and i'm repeating it here FYI.
i have heard good things about Danny, so i'm gonna try him out.

Hey, i got outta the building mode now it looks like i'm back!

this group was getting too quiet anyway.  i think i'll get the list
and start down it and ask you to write something witty.

------------------------------------------------------------------

ok, let's get serious here.  i want YOU to get off your TV chair when
you get home and do the following.  think about what you'd want on a
8.5x11" sheet of paper showing your shack, etc.  NOW, before July 31
send me photo(s) and QSL card.  i'll scan them in and then print them
off for another 8.5x11 3-hole punched packet for distribution.  i think
it'd be nice to see the latest and greatest from Ed, Jim, Jeff, Doug,
and the rest of the group.  i'll return the card and the photo later.
i promise.  i don't have much room left anyway.  ;-)

this will be the QRP internet Hall-of-Shame Book.  :-)  at least a
photo of the rigs even if you wanna be anonymous.  afraid that i
might recognize you at some swapfest?  don't wanna talk to me?  OK,
i understand.....

All,

Isn't this weekend the ARCI QRP contest?

I am desperately trying to finish my Quad.. about .00001%
chance.. but worth a try... I have both elements built..
just need to tweek the driven. .finished it about 2 seconds
after the beginning of a major thunder storm.. got up at 6am
and adjusted it a little better.. putting it together was
the easy part. Getting the mast and the antenna up and all
the rest of the stuff is going to be fun.

At the Indianapolis Hamfest last weekend, a vendor in the flea market
was selling a telescoping, fiberglass, portable mast called the Pogo Stick.
The mast extends to about 25 feet, is lightweight, and collapses to about
4.5 feet in length.
To demonstrate, the vendor had what looked like a one element quad
mounted on the mast.
I was very interested, a couple Pogo Sticks might be ideal for QRP
portable operation, until I saw the price, about $100.00.
An extension to 30 feet was extra.
If the price had been closer to a buck a foot, I might have bought one or two.

Jeff, sorry but the Summer Homebrew Sprint-CW contest was LAST sunday
from 2000-2400Z.  i missed it to, but did work KP4DDB at the tail end
of it.  guess i could submit a log of one contact.  go for the lowest

Subject: No thanks, Deer

Twice in the past month I've come home to find the coax that connects at
the feedpoint of my inverted vee broken.  At first I thought it might be
neighbor or landlord sabotage, and was miffed.  But then, a clue:  my
fiancee saw a deer in the backyard.  Exploring further, I noticed that deer
are apparently hanging out in large numbers up there--the weeds are
flattened, and there are hoofmarks and other tell-tale signs I won't
elaborate on.

Apparently the deer can't see my black coax too well at night, and simply
trundle into it, putting two or three hundred pounds of pull on the hapless
PL-259.  Guess I'll have to get it up off the ground.

Anyone else ever have animal problems with their antenna?

At the Indy Hamfest last weekend, I purchased the following items.

Two National Velvet Verniers for $7.50 each.  I thought that was
the buy of the day.  The dials are metal and were corroded when I bought
them.  I polished them up with some extra fine steel wool and now they
look great.

Four 100 pF air variable capacitors for $0.25 each.  These are double
bearing units with a ball bearing in front.  They look "new", there
isn't any solder on the terminals.  I'll make VFO's with these.

Two 100 pF Hammerlund air variable capacitors for $0.50 each.
I'll make a transmatch with these.

I also bought a pile of books for $0.50 each, including a copy of an
RSGB publication on test equipment, and a copy of a Heathkit manual
for the VFO that I think goes with the HW-16.  I have no need for the
VFO manual.  If anyone needs it, send me a big enough S.A.S.E. with
enough postage and I'll send it to you.

Eight rubber feet for $0.50 total for some cabinets I have.

A vendor in the flea market was selling a Ten-Tec Power Mite for $40.00.
I thought that was too much.

Another vendor in the flea market was selling a MFJ 20 m QRP rig for $110.00.
I should have bought it but I was too poor.

A vendor indoors was selling new 2.2 Ah, 12 V batteries for I think $6.00.
I already have enough batteries so I didn't buy any.

It was a good hamfest.

Subject: MFJ 20m Rig


Jim, WD9EYB, in his new posting (thanks Jim) told us about the Indy
swapfest.  good show on his pickings.

he mentioned the MFJ 20m QRP rig for $110.00.  that's Rick Littlefield's,
K1BQT, design.  in the Jan 93 QQ, Dave Benson, NN1G, has a later update
on the design.  Danny Stevig, see previous postings by group, has kit
for $49.95 + $3.75 for postage.  this gets you the two boards plus all
the components on the board and the air variable.

so, you'll then need the famous K5FO cabinet and plugs for power, antenna,
key, and phones and switch and knob and pointer and you'll have a rig
ready to rock and roll.  i've got one on order and hope to have it by
next thursday or so.  hope to build it and use it mobile on the way to
OKC, but i'm not holding my breath.  i know that dave little, NF5U, used
an MFJ rig for a while mobile and had great luck with it.  he got a little
cassette critter from radio shack that took audio in from plug and went
to car stereo to jack up the available power.  can you imagine having
a 200 watt car stereo system, like some of the kids today have, and
get some cw going on it and pull up to a street light and "CRANK IT UP".  :-0
;-)

i digress agin.  anyway, he sold the MFJ and got a TenTec Corsair ?? now.
Dave's picture was in QQ a few years back at the wheel of his auto or van.

there's an article in one of the latest 73 magazine issues on mobile cw.
if i remember correctly, MFJ 9020 in a Hugo (a REAL QRP rig).

i remember Ed Hare doing mobile QRP cw too.  forget the setup.

going back to the original point.  for about $60 and some change,
depending upon the junk box, you can get going pretty cheap and get
some experience to boot.  NN1G in his article notes that this is not
a beginners project, but i don't think it'd be too difficult.  again,
i'll post my feelings when i get the rig.

my $0.02 worth again and i'm just gonna have to start charging more... :-)

Subject: PROJECT 1: 40M QRP XMTR


Hi Gang,
   Here is the first of many very SIMPLE QRP transmitters. I make no
claims to their performance! In the next few weeks I'll give you xmtrs
for 80, 40, 20, and 2 meters; most requiring 3 or less transistors.
The circuits come from 2 out-of-print ham projects books (c. 1968) so
I will assume there will be no copyright problems.
   Project 1 is a simple 40 meter xmtr; it should only take 15 minutes
to build it (if you've got the parts). I wasn't able to draw the symbol
for each part on this terminal, so I put the part number in it's
place. Hope you don't mind... Note that the case of Q1 should be
grounded. Here's the text for this project, taken from "101 EASY
HAM RADIO PROJECTS"  by Robert M. Brown, k2zsq/w9hbf and Tom Kneital,
k2aes/wb2aai:

   "Want to really shake up your next contact? Just tell him you are
using this one-transistor CW rig! Most Novices and other hams shy
away from these little gems thinking they are hopelessly underpowered.
Not so! More than 50 contacts - all located over 75 miles distant -
have been logged with this rig connected to the backyard longwire!
   "Construction is quite simple and, in fact, there is not much to
say about it. Reason: there isn't very little that can go wrong!
   "L1 should be adjusted for maximum deflection on an FSM as the
key is depressed. Crystal should be a fundamental frequency type
for 40-meter operation."

Parts list:

C1   68 pF capacitor
C2   .015 uF capacitor
C3   10 pF capacitor
L1   25 turns of No. 26 enameled wire wound on a 3/8 in. slug-
     tuned form (National XR-91 or equiv.)
M1   4.5 volt battery
M2   40-meter fundamental freq. crystal
Q1   GE-9 transistor
R1   91K resistor

That's it! Note that GND = ground (and note the polarity of M1).
For Q1, I've labelled its leads B = base, C = collector, E = emitter.
* indicates a junction of 3 or more leads.
Remember, no flames if it doesn't work; I'm just the messanger!
Project 2 will be an 80M VFO QRP xmtr; stay tuned. (Oh yes, there
IS a 2M xmtr on the way).

   From: [e-mail] (Wayne Burdick)

   Twice in the past month I've come home to find the coax that connects at
   the feedpoint of my inverted vee broken.  At first I thought it might be
   neighbor or landlord sabotage, and was miffed.  But then, a clue:  my
   fiancee saw a deer in the backyard.  Exploring further, I noticed that deer
   are apparently hanging out in large numbers up there--the weeds are
   flattened, and there are hoofmarks and other tell-tale signs I won't
   elaborate on.

   Apparently the deer can't see my black coax too well at night, and simply
   trundle into it, putting two or three hundred pounds of pull on the hapless
   PL-259.  Guess I'll have to get it up off the ground.

   Anyone else ever have animal problems with their antenna?

I was visiting a commercial site this weekend norht of Dallas that also
contained an amatuer repeater.  The site also contained several cows.  The
hardline feeds came down the tower to the radio building which was only a
couple of feet from the tower.  Apparently the cows enjoyed walking between
the tower and the building.  They had trouble negotiating the hardline.
One such hardline had a nice 180 degree kink in it.  While I was there, I
observed the cow become tangled and untangled with the hardline.
Fortunately for us it was not our repeater hardline.

Subject: schematic OF-1 Osc


Gang,

i'm took a second this morning an entered the schematic for the
old (and i mean old) International Crystal OF-1 LO Oscillator circuit.

for you young critters, International Crystal, manufacturer of crystals
in Oklahoma City OK, made a small 1x1" board oscillator kit that ran
off of 9 to 12V.  i used one in 1970 timeframe on 40 meters and best
distance was ND from central texas in an apartment using long wire
hidden along eve of apartment complex.  clandestine operation as K5FJZ.

i used a Drake 2A receiver with it, qsk, no switches or t/r circuitry.

anyway, i want to see how many of you guys/girls can print and display
postscript files.  if you can, send me email.  i'll mail you the
schematic.

the program to do the schematic i wrote myself and haven't invested
that much time in.  i was doing a book on graphics and thought that
i had enough functions written to easily put a front end in and get
this as a byproduct of my efforts.  worked out pretty nicely, if i
do say so myself.  i'll throw in a copy in the schematics this afternoon.

the file is 2202 lines and 39,295 critters.  you don't wanna list
this out, just send it to a postscript printer.

if you have a HP plotter or Amdek plotter i can send you the commands
that way too.  dealers choice...... default is postscript, unless i
hear otherwise.

i'll send copy to Bruce and he can put it at the ftp site.

the circuit works from 4 to 22 Mhz with the 220pF values.  if you really
want to beat on your ears and get on 80Meters, then substitute 470pF
values for C1 and C2.

i'll have to breadboard up one, or maybe somebody on the net already
has one going, but if i remember correctly (and i probably don't) but
i think it's 500mW.

i used the thing direct to the antenna with no TVI.  nowdays i'd add
a 5-Element Chebyshev Low-pass Filter just to be on the safe side.
too many lawyers lurking out there now.  ;-)  :-)  sorry Mr. Savage. :-)

more complicated circuits, like the new mxm rig take almost 500,000
characters in postscript.  i'm working on seeing how the Tango program
does.  the input data is only 179 lines at 6,121 characters.

ok, i leave it as an exercise for someone else to pass along circuit
board layouts.  :-)

* I just did what the instructions said and did no tuning (yet)
----------------------------------------------------------------------
The Saga Begins:

    I really wanted a directional antenna. All the work involved scared me.
I saved for a while and went to the big Hamfest in Huntsville, Al. This was
my first big ham fest. I had enough money to buy a two element 3 band Yagi.
I would then save for the tower and the rotor.  I went to the hamfest and hung
around the antenna booths asking a lot of questions.  I came across the Gap
booth and there seemed to be a bunch of people who had previously
purchased a Gap Vertical and were very happy with their purchase. My elmer
has been using the Gap with very good results for a long time.  I ended up
spending my money on a Gap.  The Gap was very easy to assemble and put
up and I have used it for two years.

    I really love QRP and was getting the directional antenna bug again. A
friend has a quad and I think they are really nice looking and have heard him
up against a local Mosley tri-bander chasing DX. The quad seemed to get
through a lot better. About a year ago I sent for the literature on the Lightning
Bolt five band two element quad.  I read a lot about the pros and cons of
quads versus yagis and decided on a quad. The work involved and the cost
kept me back.

Progress
    A friend offered me 30 foot of tower that matched 30 foot of tower that
held my TV antenna, this was the first sign that I needed to take some action.
The second sign was that my TV antenna was about dead.  The third sign was
the article in CQ magazine saying the Lightning Bolt really worked well.

    I took the old TV antenna down from the tower and mounted a new
one on my roof attached to the chimney. Had loads of fun with wrong parts
and such.  This freed up my tower. The only problem was that I had very
large trees all around the tower. I got out my chain saw and tuned it up. I
ended up having to take down seven trees that were all 70 foot or bigger.
Luckily a new ham friend happened by with his pickup and helped out.
Instead of cutting up the trees, we hooked them to the truck and pulled them
into some acreage I don't use.

    I then had to pull the top of the tower off and added an extra 10 foot
section and put the top section back on . This turned into quite a project. This
was bested by putting up of the 21 foot section of thick walled steel pipe. I
think anyone who puts up a tower needs to find a friend with a Cherry Picker.
Without any special devices except for a climbing belt and rope, we managed
to drop the mast down through the middle and back thru the appropriate
support.

Building the Antenna

    All of this was taking place over a month and a half period.  My
antenna had arrived about three weeks after cutting down the trees. The
intsructions were only a few pages long.  There was only one unclear part in
all the instructions. This involved the tuning stubs for the reflector element.
There is a section that describes an eight inch variable stub and then the next
section gives exact measurements for the stubs for each of the 5 bands.  I
chose to use the specified measurements and didn't figure I wanted to mess
with this antenna if in fact I ever got it all assembled.

    I took my time building it. I assembled the spider parts one night then
built the reflector then the driven element. You only need to be careful with
the wire. It likes to coil back up and could really get you hurt if you let go of
it. We were pretty carefull cutting the wire which was a little hard because of
the type of wire, but nothing to worry about. It is really pretty easy to put
together and very light.

Finished

    Well we finally got everything built and I wanted to see the antenna
work. The temperature was about 99 degrees and much hotter on the roof.  It
took about 5 hours in the hot sun getting the elements on the boom and the
rotor working right.

    I went into the house very nervously. I took out my MFJ digital
antenna analyzer and hooked it to the antenna.  I let out a big sigh of relief
and went outside yelling and screaming. My friend who was helping me was
still strapped to the top of my tower and was very relieved to hear the good
news.

On the Air

    We were both pretty heat sick at this point, and drenched.  I turned on
the radio and actually plugged in a microphone, something I hadn't done in a
while. I worked VP5M in the Caicos Isands on 15 meters, then I8UDM first
call thru a pileup on 17 meters, CT1GG/CU3 first call to the Azores on 17
meters.

    I hooked up an antenna switch and went back and forth between my
Gap and the Quad. the Gap would read 51 and the quad would read 57 to 59.
In some cases I couldn't even hear the station on the Gap and he would be
nice and strong on the quad.

The Real Test

    WS4S, the only other QRPer in town came over the same evening to
help work on a friend's tube rig. He had to play with the new antenna before
we started on the rig.  The first thing he did was turn the power on the rig
down to 1 watt and worked 4X1EL, after which I worked him also.

    He was grinning and getting ready for some serious experimenting. He
turned the power down to 20 MW and wokred Z36CXN in Macedonia. I
really wanted the same station, so I cheated and cranked the power all the
way up to 70MW.

    Next he said. "this will be futile, but I am going to call CQ." He turned
the power to 50 mw and called CQ once. He said, "this is futile."

    I said, "you better stop talking about QRP that way, try again."

    He called one more time and YO8CDC came back to him. He talked to
this guy on 20 meters and turned the power down to 10mw. The RST was
549.

    Next he worked HA5HC in Hungary. He started with 50mw and the
RST was 579. He started chatting and turned the power dwon to 10mw. The
RST was now still 579 and Emil reported the signal was nice and strong.
Next he turned the power to 1mw and the RST went all the way down to 559
with a good report. Conard, WS4S talked with Emil for quite some time on
LOW POWER.

Guess

    Well my feeling is the antenna is working ok and that I got my money's
worth. As I keep saying, "you shouldn't have low expectations on
performance just because you are using low power."

(I think that was the magazine, and not 73) when by the article on
WARC bands I saw an add for an Atlas Radio transciever for (gulp)
about $800 plus more for power supply that could do 5 watts by front-
panel dial, but normally ran higher than that.

Anybody familiar with Atlas Radio products, particularly this one?

Michael Stein pointed out to me that Intl. Xtal had some other stuff in
their 1969 catalog, like RF amp, power amp, rf mixers, and broadband
amplifiers.  i do not have those schematics.  if someone has those,
the schematics thereof, we'd me most appreciative to get them and
distribute them.

i hope this is not a waste of time.  since 1969, we've probably come
up with better designs, cheaper, etc., but you never know until you
play with them.  i was looking for something for the beginner to
play with, not spend a lot of money on, learn how to solder etc. and
actually get on the air.

i may be going down the wrong path on this and i'm willing to listen
to anyone at any time..... the doors always open.  come on down....

p.s. i did tell you that one of the administrators in this office in
dallas was the daughter to the founder of Internation Crystal.  is
this a small world or what?

Jeff,

good review.

i hate to be so dumb, but i remember maybe seeing an advertisement
for the quad in one of the popular magazines.

can you tell me where i might see the ad?  how much for this puppy?
list price?  discounted?  who is the manufacturer?

inquiring minds wanna know.

i'm impressed by your review.  you just have too much time on your
hands.

also, as a cw op, you had BETTER move the 10 meter point down about
650 KHz or the CW Police are gonna show up at your very own doorstep.  ;-)

OK, it'll probably mess up everything else, so since the spots are on
the decline and the lower bands are ok, DFW (Chuck Adams Don't Fool
With It Rule) is in effect........

guess Tennessee may be rare for QRP and you'll be 5 Band DXCC before
you know it.....

72 de k5fo   dit     dit   QRO at 2 watts.

p.s. we assume that you used the famous OHR WM-1 to get the
accurate readings for QRPp levels.....

Subject: Hamstick Mobile Antennas

I read Chuck's account of going mobile CW, and Jeff's antenna review, so I
just had to tell you about my Great Antenna Adventure.  August 2nd I will be
mobile on 20 and 40 cw as I make the trip to Kansas to visit my father.  I
am traveling alone, so if you hear me calling cq, answer.

Ok, guys, here comes my adventure with an antenna.  About a month ago I was
inspired to take my rig with me when I make my trek across the US to visit
my father in Kansas.  So, I needed a mobile antenna.  I purchased the
hamstick model from Lakeview Co., Inc. 3620-9A Whitehall Rd., Anderson, SC.,
803-226-6990.  I bought the 20 and 40 meter resonators and the triangle
mag mount.  Came to about $75.
     About a week or 10 days went by and one day the Big Brown Goodie Truck
stopped by and delivered my antennas.  Wow was I excited.  I immediately
opened up the 40 meter resonator, read the instructions, albeit not too well
as you shall see.  I quote:
     "Note: The Exposed whip lengths shown are approximate.  Actual lengths
will depend on several factors including mounting position, coax length,
other antennas in the area and matching method.  Again do not allow the whip
to enter the close wound loading coil area of H.F. antennas."
      This was the paragraph that led me astray.  Ah hah, they don't want any
whip in the coil part, ok....so I looked at the suggested length chart for the
40 meter band....let's see if I want it resonant at 7.000, it needs to be
about 40" long.  Hmmn, usually they are off a little....the total length is
47" so I will cut 5" off.  That was going to give me 2" extra.  So, I went to
the shop, got out the hack saw and cut off 5" of the whip.  BIG BIG MISTAKE.
Notice that I did not hook it up to the rig and check the SWR,  nooooo, not
KI6DS, he is too "smart" for that!  After I cut off the whip, I put it in the
resonator, tightened the screws and mounted the antenna.  Tuned the rig to
7.005 and checked the SWR.  OH MY GOD!!! It was about 5 to 1.  Whoops,
started up the band, tuned farther and farther, the top edge of the CW
portion coming up, let's see, darn, SWR still out of sight.  I'm beginning to
realize at this point that I have done something terribly wrong.  I am
hoping that the antenna will at least be resonant in the SSB portion,  no
way, as I approach 7.3 I find out that the antenna has an SWR of 3.5 to 1,
entirely unacceptable.  When I finally found the resonant frequency, it was
at 7.445, not really a great spot for mobile cw work.
     I called the company.  Butch was really nice, told me that yes I had
screwed up by cutting the whip, but not to feel too badly, I wasn't the
first to do so......that made me feel really great.  I asked and was told
that another whip would be $6...so I ordered one.
     Now those of you who are astute will be saying "why didn't he use the
other whip from the 20 meter antenna?"  Not to be, my friends, as you see
Dougie, the antenna wizard of the west, had also trimmed the 20 meter whip
at the same time as he was trimming the 40 meter.  It was even worse, as I
cut 7" off the 20 meter whip.  Why did I do that?  Dumb I guess, I don't
know.  (You aren't the first to ask, my wife beat you to it!)  Shoot, I had
the hacksaw in hand, one whip was cut, might as well get the other one done
while I was at it.......
     What was the fix?   Ok, here is the solution that I found.  I got a
piece of 1/4" round stainless steel rod, cut it 2 inches long, put it in my
milling machine and faced off both ends square.  I then drilled an 1/8"
hole in each end about 3/4" deep.  Then I drilled and tapped a hole for a
4-40 screw about 1/4" from each end to hold a set screw.  Put the end of the
whip in one end, the cut off end in the other, and instant connector.  Works
like a charm.  Doesn't look too good, but I tell all of my friends that it
is a "special thig-a-ma-jig that goes on this antenna".  They look at it,
shake their heads and mumble about "antenna's are weird" as they look at the
SWR meter that is reading 1.1 to 1.
     How does the antenna work?  First contact was with a Salt Lake City
station.  He gave me a 579, I was using 2 watts.  He was a 599, but he was
running 100 Watts to a dipole up 60 feet.  Second contact was on 20 meters.
Yes, I had to make "two of those special connectors", but at least I have
a matched pair!  Har Har.  The second contact was SSB, using 2 watts.  Talked
to a guy on a sail boat about a 100 miles off the coast of Mexico.  He was
flabbergasted when I told him I was running 2 watts in to a mobile antenna.
     Hamsticks are good antennas.  They are cheap, about $18 per band, the
mag mount that I bought cost $35, but it holds the antenna with no problem
going 75 mph down the freeway.  I recommend them.  They get out, they are
easy to tune (but for heaven's sake don't trim the antenna whip until you
check the SWR first).  If you have questions or brick bats, send them to me
hear on Internet.  72, Doug

Doug,

good review.  i have the hamsticks also and have for many years.
in fact, two are still in the wrapper.  i have used the 40 and 20
meter versions with good luck.  for 10 meters i use a mag mount
CB center loaded whip.  i got the whip for about $25 at a truck
stop.  the centered coil is made of steel and this baby will take
a KW.  ever heard of a truck driver running qrp?  notice on 10 meters
mobile when truckers are near there is a lot of SSB splatter on the
low end?  notice that the receiver front end overloads all the time?
i do.  :-)

i was thinking of bringing my OHR 20 meter qrp rig to work and during
lunch going out to the pickup truck and working 20 qrp.  but it's just
too darn hot in texas this time of the year.

40 meters was open this morning to JAs, VKs, ZLs, and the pacific.
called JH but he went back to a 0 in kansas.  didn't have time to
try for the others.

The last I heard, the MFJ loop was vaporware. The Isoloop
works but it's big bucks. Your friend should read
"Low Profile Amateur Radio," by somebody on the ARRL
staff. It has some plans for cheap loops that work well.

wow, what a list.  ok, your credit line is now $2 or more, if you sent
more.

Bob N3MBY, sorry, but i didn't open the envelopes until today.  i'll
send your boxes out tomorrow.  sorry about that.  i promised i wouldn't
open them until i was ready to ship and didn't think that i'd have box
orders mixed with schematics.  my mistake.  :-)

Jim Price, K6ZH, what is your snail mail address?

thanks to those who contributed with schematics.  your copy in the
mail.

before i arrange part 2, let's see how you guys like the first
edition.  give me feedback and let me know if it's money and time
well spent or am i just outta touch with reality.  i've gotten
permission for some more in the next group.  i wanna expand to
back issues of Ham Radio, etc.

let me know what you want and need.  i'd offer a freebie for contributions,
but i'm sorry i can no longer do that.  the cost of the postage is
just outta sight.  and to think they (USPS) want to go up more.

if a hole punch wound up in a bad spot, i haven't checked, then
let me know and i'll figure out an update and what have you.
if we need to dig up detailed parts lists in some areas, we probably
have enough talent in this group to do it.

how many of you have NEVER NEVER put together or experimented with
a qrp rig or other?  don't be ashamed.  i just want a statistic to
see how much help we can give out that would be helpful and others
on the qrp can contribute.  thing for us to do is to find closest
Elmer for you.

for now 72 de k5fo    dit    dit


p.s. if you sent check last few days, don't worry.  if your name not
     on the list, let me know...........

Subject: Small Solar Panels & Controllers?


    I'm just getting started in solar power qrp.  I
am looking for a very portable (backpack-able) solar power
set up.  I've corresponded with several companies
(Antenna West, Sunlight, Real Goods) and they seem to
recommend solarex MSX-10 (10W) panel and either the M2
or the Sunlight controllers.   I have a 4.5 Ahr gel cell
and will probably get a 40Ahr battery later (and no I do
not plan to backpack with this one...).  The qrp rig is
a MFJ-9040 (40m, 1A transmitt, 40ma receive, though I am
planning to get a new qrp rig which is 1A trans & 140ma rec.)

Does this sound anywhere near sane?  I am concerned that
the MSX-10 is only a one year warrentee, while a Siemens
M20 (yes I know it's about 20W, 100 sq inches bigger, 3 lbs
heavier, and I don't know how much more... )  has a 10 year
warrentee.  Should I even worry about this?  Lastly, can I
run my qrp rig off the battery while the panel is charging
(or whatever) the battery through the M2 or Sunlight
controllers?

thanks,

Subject: Heath HM-102 Wattmeter

I have a Heathkit HM-102 Wattmeter that I am trying to convert to use with QRP
transmitters.  If you are not familiar with this meter, it is a 200W/2000W
wattmeter and SWR Bridge.  The sensor circuit consists of a large (12ga) wire
connecting the input and output SO-239s.  This wire passes through a toroid coil
with 17 windings on it that forms a transformer, providing a RF signal to the
circuitry.  Clear as mud?  Anyway, in my infinite wisdom, I figgered that a way
to improve the power sensitivity of this meter would be to add more turns to
the toroid.  I removed the coil, and thought (key word: thought) that I
understood how the coil was wound.  I thought that the coil was just a center-
tapped winding on the toroid, providing balanced power input to both sides
(forward / reverse) of the SWR circuit.  I removed the old windings from the
toroid, and rewound the coil with more turns.  The wattmeter now works fine,
with relatively accurate readings at the 1 watt level.  However, the SWR
bridge is now worthless.  I get full scale deflection on forward and reverse.
I suspect that I have wound the coil wrong.  Does anyone have one of these
venerable old meters who would like to check out the coil and tell me for sure
how it is wound?  Or, do you have any other ideas?  I have checked the obvious
things: the dummy load is OK on another SWR bridge, the switch,etc are wired
OK...

I would appreciate any help.  I am feeling kind of stupid right now.  But,
nothing ventured, nothing gained.  I feel like I am just this || close to having
a really nice QRP Wattmeter/SWR Bridge.

Gang,

guess i didn't post separately and i'm sure i wasn't clear.  so let
me try again.

i'm interested in putting together a Rogue's Gallary of the internet
qrp group here in netland.  so, get off your bench and take a photo
or photos of rig(s), antennas, and whatever your proud of in the
qrp world and send them to me.  i'll scan them in and come up with
a 8.5x11 page on each that i receive and we'll include them in the
next phase of schematics or do them separate.  your cost is the
printing and postage only.

it is rather timely, in that Jeff M. Gold, noted author and contributor
to this group, sent to me two photos - one of himself and the other
of his son Danny.  both these guys have appeared in a QST article that
Jeff did on the MFJ 9020 rig operating from his front yard.  he has
also got another article coming out in next month's QST.  in his
photo i recognize two mjf qrp rigs and the hw9 in the background,
but for the life of me i don't recognize the two rigs he has in
his hands.  Jeff, tell me what they are.

so let's get started on this one and don't miss the bus.  get those
cards and letters in to, K5FO, Chuck Adams, 830 waite drive,
copper canyon, tx  75067.  i'm good in the callbook since 1987.

there is no copper around that i have been able to find, but then my
long wire seems to be working great.  40 meters at 1500Z today was
open to KS with 2 watts.

i haven't gotten my QQ this month either.  guess they are late again.
i'll see Luke W5HKA on saturday at the OKC swapfest.  maybe find out
when we will be getting it.

i'm looking for a TenTec rig and hope to find one in OKC saturday.
anybody else doing any swap meets this weekend?

i'll be seeing the OK qrp group (that's Oklahoma) and i'll probably
wind up speaking at the session too.  ;-)

I heard second-hand that the July issue of Practical Wireless is either devoted
to QRP or has several QRP articles in it. ( I think Practical Wireless is the
correct title.  It is an amateur radio magazine published in England. )  Can
anyone elaborate on what articles are contained in the July issue ? Anything
good ? Reviews ? Contruction articles ?

Doug Quagliana, KA1UPW, mentions the July 1993 issue of
Practical Wireless. YES! The theme of the issue is QRP!

Here are the highlights:

Pg    Article

20    Review of Santec MX-14S 14 MHz SSB/CW QRP handheld
    transceiver, by Clive Hardy, G4SLU.

21    The Tiny Tim 3.5 MHz SSB Transceiver, Part 1. Tim
    Walford, G3PCJ describes his delightfully simple
    QRP SSB transceiver. (Only receiver schematic in
    this issue, but should be buildable with US parts.)

25    My QRP DXpedition to Monaco. Peter Barville, G3XJS
    tells the story of a successful holiday in France,
    with a day trip to Monaco thrown in for good measure.

28    The World of QRP. Leighton Smart, GW0LBI invites you
    to join in and explore the world of QRP.

30    The Queensbury 7 MHz CW Transceiver. Steve Ortmayer,
    G4RAW and Clive Hardy, G4SLU, invite you to build a
    simple CW transceiver and have fun on the air. (SBL-1
    based direct-conversion receiver, xtal-controlled
    transmitter.)

36    The Challenge of QRP. Frank Lee, G3YCC says that
    there's an exciting challenge waiting for you, when
    you work with QRP amateur radio.

40    The Bourbon QRP 3.5 MHz Transmitter Part 1. Bill
    Mooney, G3VZU introduces his 3.5 MHz double sideband
    suppressed carrier and CW transmitter, which uses
    surface mount techniques. (Usually, the Brits explain
    how they came up with the names they like to give to
    their QRP rigs. I didn't spot any clues in this article.
    Maybe he just likes Wild Turkey?)

46    Antenna Workshop. Peter Dodd, G3LDO explains how you
    can maximise your QRP transmissions, by paying proper
    attention to your antenna. (Get it high, good ground,
    comparison of horizontal to vertical.)

You might be able to find a single copy at a BIG city magazine
stand. Nothing really unique in this issue, so I wouldn't go
to great lengths or expense to secure a copy.

Subject: PROJECT 2: QRP 20M CW TRANSMITTER
Cc: [e-mail]


Hi Gang,
   Here's the second QRP project taken from 101 EASY HAM RADIO PROJECTS,
by Robert Brown and Tom Kneitel; again, since the book is out of print,
I assume there will be no copyright problems...
   This project is a simple 20 meter CW xmtr with output about 100 mw (?).
Here are the authors' comments:
   "If you have always wanted to try low-power on 20 meters, here is an
excellent method for joining the growing ranks of flea-power addicts -
and doing it inexpensively. This circuit is capable of world-wide QSO's,
given the right conditions and assuming QRM is not present.
   "The transmitter uses a pair of GE-1 universal replacement transistors
in a unique circuit configuration a great more sophisticated than you
would normally expect for an under-one-watt rig. Crystal can be a
fundamental 14-mHz type.
   "L1 should be adjusted for sure-fire oscillation every time the
key is depressed. C4 is simply adjusted for maximum output on the FSM."

PARTS LIST:

C!, C2     .02 uF capacitors
C3, C5     .002 uF capacitors
C4         51 pF variable capacitor
L1         38 turns of No. 22 enameled wire on a 1/2 in. diameter
           slug-tuned form
L2         8 turns of No. 22 enameled wire wound over cold end of L1
L3         Coil, 17 turns of Air Dux 616T (or equiv.) tapped 5 1/2
           turns from cold end
L4, L5     2.5 mH rf choke (National R-100 or equiv.)
M1         1.5 volt dry cell
M2         6 volt battery
M3         14 mHz crystal
Q1, Q2     GE-1 transistors
R1         180 ohm resistor
R2         1.1 megohm resistor

As before, rather than trying to `draw' the symbol for each component,
I've just inserted the part number. Oh, note the polarities of the
batteries M1 and M2.  GND = ground, ANT = antenna, E = emittor,    ANT
C = collector, B = base, KEY = well, this is a CW rig....          |

Subject: Alignment Inst. for NN1G

Dave Benson sent me the following instructions for building and aligning the
NN1G 20 meter transceiver that he describes in the Jan. 93 issue of QRP
Quarterly.  Danny Stevig, of Dan's Small Parts and Kits, 1935 S. 3rd W. #1,
Missoula, MT 59801 Phone [phone] is selling a kit that consists of pcboard,
all pcboard parts and variable capacitor for $49.95.  No I don't get a cut, or
rate, just providing info.  Here is the information that Dave sent me.

BUILDING AND ALIGNING THE NN1G 20 METER TRANSCEIVER
FROM JAN. 93 QRP QUARTERLY
By Dave Benson, NN1G

Building Tips:
1.  Use sockets for the IC's.  The added lead length isn't too critical at
    these frequencies, and troubleshooting/replacing these devices becomes
    much easier.
2.  Check the 10.7 MHz transformers for winding continuity with an ohm meter
    before you solder them in.  An open winding isn't that easy to track down
    (especially without test gear).  You'd be surprised how often the parts
    are defective, even when new!  By the way, it doesn't take much DC current
    to burn the windings out, so try to avoid inadvertant shorts to power/gnd
    if you need to troubleshoot.
3.  Transformer winding polarities are non-critical.
4.  The LO inductor L1 is tricky.  It installs in the receiver board as
    follows:  With the board component side up, the coil goes in the upper
    right hand corner.   Take the wound toroid with the tap towards U1 and
    the ground end on your right and the hot end on the left.  Looking
    straight down, the ground end of the coil is on the right, the hot end on
    the left and the tap on the side towards U1.

Suggested Alignment Procedure:

Starting with the Receiver Board
1.  Connect headphones to the RX audio output and apply 12-14 VDC power.
    Some background noise should be heard in the headphones.
2.  Peak IF output transformer (T4) for maximum audio output.
3.  Use a signal from a main station transmitter to find the receiver's
    operating frequency.  This will be a function of the HFO frequency, which
    will nominally be about 4 MHz.  Due to individual component variations
    each oscillator will be different and will need tweaking.  fine
    adjustments may be made by squeezing or stretching the turns of the LO's
    L1.  If this doesn't add or subtract sufficient inductance to get the LO
    to the desired frequency, it's necessary to adjust the component values
    to bring it in.

    To RAISE the receiver frequency:  Subtract a turn at a time from L1 and
    retest and tweak after each turn.

    To LOWER the receiver frequency:  Add a small fixed capacitor in parallel
    with C1, the LO's main capacitor.  Small ceramic disks will be OK,
    although the NPO variety (the kind marked with a black tip) will ensure
    the best frequency stability.  (It's possible to add turns to L1 to
    accomplish the same effect, but that is a pain in the neck!)

    It should also be possible to add a small trimmer cap on the backside of
    the board (again in parallel with C1) if you wnat an easy variable
    adjustment.  I haven't tried this though.
4.  Open the connection between the Transmitter antenna pickoff circuit and
    the Receiver's RF Input (labeled "RF IN" on the schematic).  Connect an
    antenna to the Receiver "RF IN" Point.
5.  Peak T1 and T2 for maximum received signal strength.  You should now be
    hearing 20M signals if the band is open.
6.  As you tune through CW signals, the peak audio response will probably be
    wrong.  Adjust BFO capacitor C2 until peak audio response occurs at normal
    CW listening frequency (about 800 Hz.).  If the BFO is capable of tuning
    either the upper and lower, pick the one which gives better rejection of
    other-sideband signals.  (These simple filters aren't symmetrical with
    respect to their skirt selectivity.)  It's possible to add or subtract
    turns to the BFO tuning coil L2 juciciously to change the BFO range.
7.  Ground the Receiver "KEY" input to check that feature.  (The transmitter
    Key input should be disconnected for this step.)  The audio should mute
    smoothly and return rapidly after the connection is opened.

This completes the receiver board alignment.

Transmitter Alignment:
8.  Restore the "RF IN" connection between the RX and TX boards and install a
    dummy load on the transceiver antenna connection.
9.  Ground the transceiver "key" input with a string of dots from your keyer.
    A sidetone should be heard in the Receiver headphones.  This corresponds
    to a sample of your own transmitted output.  Adjust the TX Mixer
    frequency by tuning capacitor C3 until the sidetone matches the receiver's
    peak audio response frequency.  You should be able to tune the sidetone
    through zero beat.  Make sure that you select the louder of the two
    signals to peak on.  (If there isn't sufficient tuning range, see step 6)
    above and try the other sideband.)
10. Find the transmitted signal on a main station receiver and tune
    transformers T5 and T6 for peak signal (you may need to add a clip lead
    to Q6's collector (case) to get sufficient signal level in the early
    stages of this tuneup.  These two adjustments are somewhat interactive
    so alternate between the two several times for best results.
11. Final peaking of T5 and T6 should be done with an SWR meter in the
    "forward" position, or with an RF probe to maximize output power.
12. Let the key up, remove the dummy load, and reconnect an antenna.  Peak
    the receiver response by tuning the TX board C4 for maximum signal.  Be
    sure to use an insulated tuning tool.  (This is a high-Q network and
    body capacitance will spoil the adjustment.)
13. We're almost done!  Tune in a 20M signal on both this transceiver and
    your main station rig (separate antennas) until both audios are at the
    same pitch.  Key the transceiver.  If it's not at the same pitch in the
    main station rig, adjust TX mixer C3 trimmer cap until they match.  This
    last step ensures that the transmitted signal is exactly zero beat with
    other stations.  (This also verifies that you didn't accidentally select
    the wrong sideband in step 9.
Other niceties:
14. If the sidetone volume isn't to your liking, feel free to change with the
    existing 1M resistance value across Q2's drain/source.
15. If transmitted power output is low, try increasing the value of
    capacitance at Q5's emitter cautiously.  (Increase it onlyu enough to get
    the rated 1.5 watts output.)

I called them and they sent me a nice black and white glossy one page brochure on
this radio.  It is very nice!  (the radio - though the brochure is nice. too!)

Control layout appears very simple and straightforward.  There are only two displays -
the digital frequency readout (good to .1 kHz, if the picture of the rig is accurrate), and
what appears to be an s-meter on the lower left corner of the front panel.  Thee
is a large central knob for freq control, and a small knob for AF volume (no rf gain,
but there is a 20 dB attenuator switch).  There are two toggles  - one switches in
the rf receive attenuator, the other toggles between xcv, rit, and split modes.

Four pushbutton switches control memory read/write (there are 20), toggle rev/split
operation, and activate the SCAF digital filter (100 Hz - 2400 Hz, continuously
adjustable).  According to the brochure, the main tuning knob becomes a control to
set the appropriate value, depending on which button was pressed.

The rig is very small, measures 5.5" W x 4" H x 6"D.  It has a single leg on the
front to elevate the front panel.  Power consumption is stated as 1A @ 12V xmt,
140 mA rcv.  Freq coverage is 160M - 10M (I called them, and if my memory is
correct, it has general coverage reception across that range, plus amateur
band xmt).  Modes are CW and SSB, though I was told it will handle anything
you can put in to the mic connector (which is probably mounted on the back panel -
it is not visible in the photo).  I was told the transmitter amplifier is oeprating
in a "derated" mode in this rig - it has plenty of design margin to handle high-duty
cycle operation like RTTY.  (Note - I asked Ten Tec about this on the Scout - their
tech DID NOT recommend QRP RTTY or AMTOR operation for the Scout.)

Index labs wants $595 for this gem, with deliveries in (I think) mid August or so.
(But call them and find out for certain!).

You can reach Index Labs at 19913 48th Street, Longbranch, WA 98351.
[phone].

Now my question:  I was told that several of these rigs (beta test/early production)
were in the field for a while, including Field Day operation.  I recall reading
that one was on display at Dayton or Dallas.  So has anyone on the net
seen, or better yet, used one of these rigs?  What are your thoughts, comments,
and observations?  If you were in the market, WOULD YOU BUY ONE?  (IMHO, this
is what the Argonaut II should have been!)

Std disclaimer - I don't work for Index Labs, don't own any stock, am not related
to anyone who does, etc...  I don't even own one of their rigs (yet?).  I'm
just impressed by what they seem to have accomplished!

   Potter's Bar  EN6 3JE
   England

   phone: [phone] (local time is UTC+1 in the summer)

They sent me a prospective members package a while ago that included a
sample copy of _Radio Communication_ (a.k.a. RadComm), a sample of their
beginner's magazine (D.I.Y. Radio?), and information about the society
(books, QSL Bureau, etc.). Overseas memberships are about (pounds)35, more
if your really must have RadComm by airmail. I'll check the exact figures
and post them over the weekend.

Gang,

after Steve Greene's posting (KA1LM) i immediately called Index Labs
at the number posted.  i talked to Bruce Franklin, KG7CR.  very nice
feller on the phone and the rig sounds great.

steve is right.  this is where TenTec and a lot of the others should
have been.  the digital filter audio sounds like an exceptional feature
to have on a rig this price.  all bands and general coverage receiver
in a small package.  small current drain on receive.

the only thing that i'll ask for in the next version is qsk without
relay instead of the reed relay.

expect shipments to start mid-august.  the first one on the net let
us know.  i'm gonna wait on this one.  hoping for a tentec at OKC this
weekend.  cross your fingers for me.

look for me on 20 meters 14030-14070KHz mobile qrp this afternoon
4pm on CDT.  2100Z (UCT or GMT)  ;-)

also carrying 10 meters in case that band is open.  this morning,
6am CDT (1100Z) channels 2-34 were active.  remember i'm in the
country without cable, so i monitor periodically the tube to see
how the MUF is doing.  summer time and hot.... good for about 400 miles
on the tube.

anybody with the above critter?  i'm thinking of getting one while
i'm in OK city tomorrow.  texas towers here in dallas didn't have
any in stock when i checked yesterday.  is the $199.95 price tag
worth it or should i go with the 209 without the counter?  i have
a separate counter but would think that the whole unit would be
more handy.

your ideas please.

Subject: 12v marine battery maintenance


Hello to everyone on the list!

  I recently purchased a deep-cycle 12v marine battery to power my QRP
field excursions (including FD).  It's nothing special -- I got it at
Sears and it has about 100 amp-hrs of capacity.  I charge it up using
the trickle mode on my 12v car battery charger.

  The sales assistant at Sears was unable to tell me how to properly
care for the battery over the long term.  I've seen others mention the
use of these batteries here, so I thought I'd pick the brains of the
collective consciousness of the list.

  Between uses, should I keep the battery fully charged or fully
discharged?

  Should I load-cycle the battery after long periods of no use?  That is,
should I charge it up, put a load on it and drain it down?

  Are there any other considerations that I should be aware of?

  Thanks much and 72.

Ron (wb8ruq).

Subject: SWR Analyzer es Keyboard de MFJ



Gang,

just a quick report on the trip to "Ham Holiday" the swapfest in
Oklahoma City OK.  somebody has to drive north on I35 aperiodically
to make sure the Red River is still there and i'm here to report
that it still is.  :-)

i just went up for Saturday, which was long enough for me to part
with some of my money.

i had reported last year on the net, when there was flame wars
going on for MFJ products.  i don't think that i'll ever learn.
i'm already educated beyond my intelligence anyway.


MFJ-451 Morse Keyboard - A Review by Chuck Adams K5FO

i normally use either a Heath Ultrapro Keyboard or when i'm
practicing on the Bencher i use an AEA MM-3 or CK-2 keyer.
the heath is losing one of the memory chips for the 10 memory
buffers and i hadn't taken the time to fix it, so i saw the
MFJ-451.  thought, what the hey, it was reduced i'll just buy
one.  replace the large AT keyboard with the small one i have
on a 386 and take up less space (vertically) on the operating
desk.

the MFJ-451 keyboard has an unmodified keyboard (AT type) that
plugs into a small box (sorry, i'm at the office and don't have
the exact size).  got it home, opened the box, plugged it in,
and it worked outta the box.  didn't even have to read the
instructions.  only two parts and parts is parts, right?

ok, get the instructions, get through them in short order and
know how to set the speed, load the two buffers, adjust the tone
(the volume controlled with a knob on the little processor box),
learn to program the beacon operation up to 99min 99sec delay,
and use the serial numbering in time to use it for SS.  :-)

ok kids, so far so good.  fire up the QRP rig on 40 for the sunday
morning schedule and call cq.  get another qrp in st louis mo.
worked about 20 minutes at 30 wpm and stood by for the group.
no answer and the other guy signs.

fine.  so far so good.  ok, 40 not all that hot, let's go up to
30 (another fine QRP band).  WHOW BUCKAROO!!  it is very very
obvious that noone at MFJ works 30 meters.  this little keyboard
sucks canal water when it comes to putting out trash on 30 meters.
it's S9+ and then some.  i can't hear the digital guys above
10.110 with this thing on.  ;-)

ok, look at the schematic.  uses 80C32 Intel processor clocked at
***10 MHz***.  only decoupling caps in the system are four 0.1uF
caps.  bad news.  ok, i'll help, give me phillips.  two screws to the case
and its apart.  hey, nice little board, double sided silk screened
plated through solder masked.  not bad.  ok, three more screws to
remove board and a model airplane prop-nut driver to remove volume
control nut.  board comes out and i turn it over.  GEEEEZ!!!
we have 12 year olds learning to solder here or what?  the second
worst soldering job in the world that i've seen.  you guessed it
the first place is the MFJ-249 HF/VHF SWR ANALYZER.  see second half
of this posting.

i take pride in my work, no matter what it is, and i'd think that
others do too.  component leads were not cut short and overlapped
PC board paths and on and on i could go, but i won't.

it works, but once again, bad quality control for cosmetics.  if it
works, ship it!!!

if you plan on working 30 meters, do not (and i repeat) do not
buy this keyboard until you hear from me that they got the problem
fixed.  i thought that i'd play with some ferrite beads strategically
placed, but no way am i going to spend my valuable time doing this.
going to call them on monday and ship the little box for a revision.
or else.

i didn't pay the $89.95 list price and got a good deal, but not
that great.


MFJ-249 HF/VHF SWR ANALYZER - A Review by Chuck Adams K5FO

this is the deluxe swr analyzer by MFJ.  list price of $199.95, which
of course i didn't pay at the swapmeet.  :-)

i had asked the qrp mail group about these and got a response after
the fact and as it turns out, i made the right decision.  we all get
lucky once in a while.

MFJ has another analyzer MFJ-207 which is the same without the
frequency counter.  i have a heath counter, but i prefer to put
all my eggs in one basket and have a small self-contained unit
like the 249.  once again, outta the box, hook up 12V supply and
fire it up.  worked first time every time.  hook it up to the 80
meter long wire and check it out.  GREAT.  with the digital readout
for frequency and the analog meter for direct reading SWR, it's
very easy to see where you are and how good the antenna is doing.
checked all the bands from 160 to 10 Meters.  i had my previous
settings from measurements made at 1 watt with Oak Hills QRP wattmeter.
they were correct (of course).  but, the MFJ makes it very easy.  none
of the forward vs backward, etc.  just read it and weep or smile.

one of the questions i asked the friendy sales rep was how much
does this little puppy put out.  it obviously must generate rf
to the antenna to get the swr.  he didn't know and the MFJ manual
does not say one word.  so, couple of pieces of RG58U with PL259s
and in goes the OHR QRP WM-1 meter.  2mW (that's 2 milliwatts) out
from 1.8 to 170MHz.  constant and true.  good news as that is the
requirement to not have an adjustment for meter calibration.
i wouldn't part with the OHR for love or money.  need it for
power measurements for 10 W down to 1 mW.

i assume, since the MFJ-249 device transmits outta band (i did this
into a dummy load guys and girls and FCC) i assume that it is
type accepted or something like that.  being an avid QRPer, i
know what 2 mW can do when the bands are right.  and outside
of the ham bands you can easily get a clear frequency.  ;-)
that why the HT mods i see posted here in rec.amateur.radio.misc?????

frequency meter is accurate as tested with heath counter and
3.600000 output from the wwv clock.  without the counter (the 207), MFJ put
dial with freq markings and i understand from another individual
that has one, they aren't all that great.  not good if you're tuning
an antenna from phone down to cw band or whatever.

ok, let's look at the schematic?  what, no schematic in the booklet
or box!!  ok, take the back off.  BIG mistake big mistake (line from
Pretty Woman, the movie).  the worst soldering job i've seen.  tied
with MFJ-815B Cross-Needle 1.8-60MHz SWR/Wattmeter.  close behind
is the above keyboard system.  somebody in QC outta work on this
or start selling them as kits.  i can do a better job easily.

the counter is SMT (surface mount technology and i assume it was
wave soldered) and separate from the badly soldered board.  another
board also SMT and wave soldered for RF generator.  at least i hope
so.  i didn't want to see any more and put it back together.

so, final results.  MFJ-249 SWR Analyzer.  good deal.  MFJ-451 keyboard
is a bad bad idea.  wait til Christmas or later on this keyboard.
both are new items and maybe with feedback we can get MFJ to do
a little better.......

Subject: Swapmeet


Gang,


separate from the previous posting on the MFJ equipment, thought
i'd let you know about a couple of other deals in OK.

i took OHR 20 meter QRP rig (the old one) with me, but the
ignition noise was too much.  10 meters was dead as a door nail.


at the swapmeet i picked up a KENT iambic paddle kit.  went together
in 30 minutes or so.  nice feel and nice action.  see Jeff Gold's
previous review.  this one might replace the Bencher on the desk.
time will tell.

another funny story.  i got the kit early saturday.  in the afternoon
i was walking by the booth and two 12 year old boys were standing there
playing with the paddle.  that was about the age that i started, so i
stopped and asked them if they knew the code.  one said yes and he was
doing 4 wpm.  the other said no, but that he was interested.

so on the spur of the moment i made them a deal.  if, withing one
year they could do 13 wpm, i'd give them each a $100 bill.  :-)

they took down my name and call and address.  later they asked, what
if we do it earlier?  i said no problem.  they will send me copy of
VEC for 13 wpm and they'll get the money.  :-)  that's it for this
year for the Chuck Adams CW Proficiency Scholarship fund.   :-)
the guys were so excited.  i think their dad was excited too......

ok, the other deal.  i picked up a like brand new Argosy II from
TenTec.  with p/s.  i guarantee i got a good deal.  it has the RF
atten. mod and cw filter and it's loaded.  haven't fired it up yet.
(patience huh?)  NO, just gotta get the op postition cleared off after
i get back to the house from the office where i'm posting this.

the OKlahoma QRP group was there in force with three tables.  bunch
of homebrew stuff.  good show.  saw my OHR Sprint there on display and
the 20 meter A&A that i assembled and sold at Hamcom in June.  the
new owner is gonna hold on to them.

Burl Keeton, N5DUQ/QRP, got his Quarterly, so they are in the mail
guys.  this is the QRP ARCI Quarterly for July.  they are mailed
from Alpine TX where they are printed.

i saw some HW-7 and 8s listed for $100.  too high.  people think
they are valuable now.  guess we're gonna get a generation of
heath collectors going.  hold 'em if you got 'em......

Corsair I for $600, but not that clean.  Omni A for $500 and some
other odds and ends.  nothing exciting.  at least for me.....

overall, i had a good trip and i'm going on record:  got the W9KNI
Dxing Companion book.  i'm going to try for 40 Meter DXCC 2W QRP CW.
start the clock.  date of start, July 25, 1993.  monthly reports
if you're interested.  anybody else want to start too.  not necessarily
40, dealer's choice.....

watch out AA2U!!  :-)

July 23,1993 0600Z  0 worked 0 confirmed   100 to go.

For those who were curious why Danny Stevig changed his company's name
when he moved, he said it was to make it easier at the bank.  He
didn't have a 'business' account, and when people made the checks out
to KA7QJY Components, he had a major hassle cashing them.

As that happened to me once on a side job, I can fully sympathize with
him.  He would *still* like the check to be made out to him, but the
'new' name will be easier on him if it isn't.

Subject: Super Cmos Keyer II Kit

I received my Super Cmos Keyer II kit Saturday from KB6NQ, and I have it
built and working.  The kit costs $25, and includes the pcboard, programmed
chip, all board parts, 4 switches, 100K pot and a speaker.  You must
supply the cabinet and connectors.  My kit did have a couple of mistakes in
the resistors provided.  I replaced them from my stock on hand, but it would
be nice if you got the correct parts..  But a minor item.  I chose to replace
the switches provided with ones that I had on hand, they were much easier to
mount, as they just needed a round hole, while the ones provided need a
rectangular one.  The speaker that I got did not work, maybe I fried it when
I soldered the leads on, but it was only 1" in diameter and not high quality
at all.  I replaced it with a 2" radio shack 8 ohm speaker, which works fine.
     The kit only takes about an hour to build.  But by the time you mount it
in your case and dress the leads, plan on an evening.  When you finish and
have it working, then the fun begins.  The keyer is fantastic.  Are you ready
for the features?  Here they are:
        Iambic keyer with selectable dot and dash memories
        Four messages totaling up to 220 characters
        Character and real time message loading
        Timed pauses within messages.
        Messages that can call other messages and contain operational commands
        Message loop capability for continuous play
        Message break in to allow for paddle inserted text
        Input queue to store multiple message activation
        Contest Serial numbering (001-9999)
        Digital and linear analog speed control (6-60 WPM, Messages up to 990)
        Adjustable weighting (dot/dash ratio) of 25-75%
        A built in adjustable sidetone monitor
        A transmitter keydown (tune) function
        Handkey mode
        Compensation for transmitter induced keying distortion
        Selectable automatic character spacing
        Keyer status inquiry functions
        Ultra low power consumption for battery operation

If you want more information, refer to any recent ARRL handbook.  The 93
edition has the article on page 29-6.  I recommend the KB6NQ kit.  For $25,
you can't beat the price.  Idiom Press sells the same kit for $45.  I am
not affiliated in any way with KB6NQ, just providing information to fellow
qrpers.
72, Doug,  Oh, by the way, if you haven't ordered the set of schematics from
Chuck, do so.  They are an excellent edition to your library.  I got mine
Saturday.  Tnx Chuck for your efforts....

Gang,

my copy of the July 1993 Volume XXXI Number 3 issue of QRP Quarterly
(QQ) arrived yesterday.

congratulations to AA2U, Randy, on this group for his 300 country
seal #66C dated 11/28/92.  this means that Randy has worked over
300 countries QRP.  determination, dedication, and lots of hard
work.

i just read W9KNI's book on DXing and i've dedicated myself to
DXCC in under one year starting date July 25, 1993.  up to 5 countries
so far.  40 hasn't been all that bad.  was hearing EU last nite about
11pm CDT (0400Z or 0400UCT, whichever you prefer).  oh, that's
DXCC 40mtr CW QRP.  gotta make it challenging.  ;-)

i'll post separately the QRP ARCI History, Purpose and Policies
for the QRP list.  do we call this group the Internet QRPers (IQ)?
are we a net (short for network)?  maybe we outta give ourselves a
name.  bad idea?  badges?  secret handshake?  just an idea..... :-)

ok, off to teach.........  i do work sometimes.........

you have a good day and good propagation,

Would like to see the Ten Tec Power Mite schematics added to the nice little
qrp circuit booklet Chuck put together so nicely.
Anyone else interested?
Anyone have these and would be willing to supply a copy to Chuck for
inclusion?
The nice series of mail generated on these classic radios was very interesting
and would like to get a copy of the schematics....

Chew on this.....

Gang,

here is the official word from the QRP Quarterly dated July 1993


           QRP ARCI History, Purpose and Policies

   The QRP ARCI was founded in 1961 by the late Harry Blomquist, K6JSS, with the
aim of reducing QRM on the air, by members voluntarily limiting their power to
100 watts or less at all times.  Due to increasing interest in true low power
operation, and through the leadership of then-president Tom Davis, K8IF, the
Club voted in the late 1970's to redefine its purpose in that direction, and
adopted the generally accepted definition of QRP as 5 watts output CW and 10
watts PEP SSB.

   The voluntary 100 watt power limit was later abolished; members may run any
legal amount of power necessary at any time, for any purpose, although the 5 watt
limit should be observed when claiming to be operating QRP.  Club awards and
activities are geared to the 5 watt and under level.  The QRP ARCI does not
advocate the reduction of the legal power limits of amateurs in any country, and
serves only to provide a forum for those who enjoy the thrills and challenges of
building and operating with low power equipment.  The QRP ARCI is a member of
the World QRP Federation and maintains ties with various other QRP organizations.

   The QRP ARCI publishes the QRP Quarterly in January, April, July and October.
All contributions are welcome and should be directed to the appropriate editor
or columnist.  (No payment is made for material published.  Unless expressly
requested, manuscripts, drawings, pictures and diskettes will not be returned.)
Except for those items with a copyright indication, material may reprinted
elsewhere if proper credit is given to the author and the QRP Quarterly.  The

the enjoyment of our readers.  No testing has been done unless explicitly stated,
and no warranties are intended nor implied.  The QRP ARCI and QRP Quarterly in
no way warrant any commercial or private offers herein unless expressly stated.

   To promote on the air QRP operation, the QRP ARCI promotes the use of
designated QRP calling frequencies, regular QRP nets, and a program of QRP
operating awards and contests.  Information on these is found in the QRP
Quarterly from time to time.  Detailed information on the awards program is
available from the Awards Chairman.  To join the QRP ARCI or renew your

i noticed on the new issue, there is a cover price of $3.  inside the QQ
there is a on page 9 a note that the QRP Quarterly is now available at
Maryland Radio Center, 8576 Laureldale Drive, Laurel, Maryland.  this
would be of interest to those within driving distance of same.  i don't
know that there is a push on to get the QQ to many commercial locations
to be sold.  this is new to me and time will tell.

the above copy is from QQ July 1993 and is for the enjoyment and
for the distribution of info on the QRP ARCI club.  there are number
of new hams that are just learning what many of us take for granted.
it's our job to give them information and allow them to make their
own decisions.  i'm personally not forcing my views on anyone but
i will give them away (my views).  ;-)

As you all may already know, I picked up a Ten Tec OMNI-D series C (the
later model - a much improved Triton IV) for a basic swap (a TS 520).  I
am happy with the deal, got break-in CW, 160, WARC, more filters, digital
display, notch, zero beat button, and way lower current drain for 12 volts.
I lost the pi-net tank circuit of the 520 (little need for antenna tuners).
It was a $300 value deal.

Anyway, it is very simple to run the ALC down for QRP operation.  The rig
is a bit large by today's standards, about the same size as the 520 was,
but a lot lighter.  There is a relay used in the QSK and you can hear it,
but it is no real problem.  There is also a relay for amplifier operation,
and I need to disconnect it.  It drifts a bit for the first hour, but then
it is rock stable.  The display (frequency counter, I think,  but I have yet
to see the manual promised to me) is large and friendly, but the last digit
will not be stable when the counter is on the borderline.

Now, the receiver is "quiet", and I finally understand the term a bit better
than I used to.  When I am up on 15 or 10 and the atmospherics are down,
and I tune in a weak one with the OMNI and my TS 440, I can tell that the
OMNI pulls the signal out a bit cleaner.  Only a bit, but I can notice.

On to my point.  I believe that there were not a lot of these radios sold,
or else the owners hang on to them.  Don't see them for sale that often.
That means potential bargains at swap meets....  Using the radio for the
week convinces me that I got a helluva radio for $300.  It has 8 pole
crystal filters for 2.4 and 0.5 Khz, and audio filters for 1.8 and 0.5.
The combination of these two with the notch does a real fair job for
CW selectivity.

The indide of the radio is clean, neat, removable boards.  Discrete
components for the most part.  Fixable, real fixable.  There is a LOT
of room inside the cabinet, topside and bottom, and I think I will be
putting a CMOS super keyer inside, maybe a little speech processor
(I frequent QRP SSB on 40 especially), and who knows all what could
go in there.  There is plenty of room there where the crystal filters
go for extra filters if I wanted to.  I may put in an extra 8 poles
at the 2.4 range for SSB, but I think I am OK with the CW filtering.

Anyway, wanted to let you all know, if you are so inclined, that the
OMNI-D is a good old rig, but not so old that you will miss a lot.  In
fact, the receiver is pretty quiet because of the older PTO technology.
It still has really good filtering, fine QSK, and has plenty of room
for playing around to customize it.  (Not that I have much time for
that, I am trying desperately to define my Ph.D. dissertation topic
this month and perhaps the next few - anyone know how to do it?)  SO....
if you are looking for such a thing, I heartily recommend it.

Chuck, how do you like your Argosy?  I believe it is the compact version
of this monster.

Hi QRP folks,

Yesterday afternoon I worked a QRPer trying hard to QSO me. He failed
cuz the sigs were too low. I did not even get the complete call:
I got KP2/K??Y? Name Ed QTH Saint Thomas (one of the US Virgin Isl.).
Confess that I was running 50 W (to a dipole). Ed seemed to have a fairly
solid copy and he was a real patient operator.

Does anybody know the rest of the call?

If yes pse e-mail to IK2RMZ ([e-mail] or IK2RMZ@W2XO.#WPA.PA.USA.NA)

Subject: QRPp


sorry about using this esoteric abbreviation.  during the early days
of QRP, when it was 50 watts, if you ran under 5 watts or so you were
QRPp or QRPP.  i guess now we have to use QRPp to mean under 0.5 watts.
that would be one order of magnitude, i.e. a factor of 10.  i just
made this up, the 0.5 value.  it's open for discussion and someone
put it to a vote in the QQ.

in Oklahoma at the swapfest last weekend i picked up a lapel button.
this button has 72 in larger font.  in smaller font it has "Wishing
You Good QRP", which is the meaning of the 72.  QRPers use 72 and 73
when signing with a worked station who is also QRP.

keep up the good work guys.

Clark, i like my Argosy II just fine.  i have sensitive ears and i find
that it does have TOO MUCH audio.  i can't move the audio gain much off
of zero before it's too loud in my old Yaesu FT-77 earphones.

i've worked five countries with 2 watts.  in the low power position
with the power level at max i only get 2 watts out instead of the 5
it's supposed to do.  this is measured on the Argosy's meter as 2 watts
and on the OHR WM-1 wattmeter also.  i cranked the output up to 10 watts
(sorry guys) to see if there might be a problem and there doesn't seem
to be.  i didn't work anyone with this high an output, it was into a dummy
load.  so i guess that makes it alright (the high power).

i have to work on the AGC, it thumps too much for me and the delay is
a little slow.  at 30 wpm it can hear between words but not letters.

ok gang, i've said enuff this week.  i'll be quiet.  ;-)

Clark, WA3JPG, asks about MFJ antenna switches.

Personally, for <100 watts, any old rotary switch
in a box is more than adequate, assuming the SWR
isn't insanely high. Time to hit the hamfests, or,
<gasp> Radio Shack!

Regarding the antenna switches..........

I have successfully used a PAIR of B&W switches.. mine happen to be the
rear connector units.

I attach my various rigs to the six poles on the "rig switch" and from
what is normally considered the feed pole, coax to the normal feed pole
of the other switch.  The "rig switch" is fed backwards from the way we
normally see these switches connected, but at HF, who cares????

The six connectors on the other switch go to a Dummy Load, Tribander and

Subject: re: QRPp

My understanding of "QRPp" has always been that it refers to an output of 1
watt or less.  This could be folk lore--I can't point to any written
references.  In support of a 1-watt figure, I would point out that this is
around the typical output from the 2N3053/2N4427/2N3866/2SC799 class of QRP
PA circuits that dominate in HF QRP projects now and have since the late
1960's.  It seems to be  a power level that needs a label of some kind.  :)

Of course, "QRPp" is also the name of the journal of the new NorCal
(Northern California) QRP Club.  Perhaps we should ask the editor (Doug,
KI6DS) what his definition is!

It would help if you could first convince a lot of ops out there, and
especially the folks at CQ magazine, that QRP means 5W or less. CQ
continues to use QRPp for the 5W or less class in CQWW and WPX.
I heard a DX station last week reply to a station who claimed QRP and when
the DX asked how much power the answer was 20 watts. I often get QSOs in the
ARCI contest from people who claim to be QRP and then I find that they are
running as much as 50W.
Once we're all agreed upon what QRP means, then we can decide what QRPp means!

Heck, I think CQ's definition for QRP is 990W or less...  ;-)

Just out of curiousity, how long has the 72 been used as opposed to the 73.

I have had numerous contacts with said qrp stations, and not one of them

 has sent me a 72 yet that I'm aware of.  Just curious.   72.5  for now..

Rod,

It's pretty routine to work the low orbit satellites with moderately low
power outputs, say 25 watts or less. The main problem would be contention
on the digital and FM repeater satellites like AO21 or the pacsats.

On Oscar 13, which has got much higher path loss, I've heard people
claiming to run 1 watt or less, heard the ZRO tests when the power to the
antenna was well below a watt on the higher levels (Z8), and have worked
stations on CW with 5-10 watts, and heard my own return at 1 watt. You need
high gain antennas for Oscar 13, but they are physically small. My helix
cost about $40, is 10 feet long, and has about 15 db of gain.

For the HF satellite like RS12/13, I imagine you can get away with pretty
low power too, but I haven't tried it.

If you can make a couple of watts on 435 mhz, and want to whip up a quagi
or something for an antenna, I'd say go for it. A couple of us have tried
working through AO13 using our 440 HT's and doing cw with the ptt switch.
Ugly, but you *can* hear it. (short the mic plug to keep the FM out - you
don't want to take up 30 khz of transponder space, even qrp)

Hope that was useful

Subject: Include PowerMite!
Cc: [e-mail]


The ads for these rigs (I think I sent away for the data sheets) were my
first exposure to Ten-Tec.  In fact, I had never heard of the company
before, and hadn't since until they started producing other more advanced
rigs in the later 70's. Just exactly what were they making in those early
days, besides the Power Mites?  Were these rigs their first product?

I have never seen one in the flesh, but wanted one ever since I saw those
ads for these cute, inexpensive little rigs!  But in those days, I thought,
how useless and undesirable was a rig that only put out 2 watts!!  Hey,
I was only a teenager, give me a break!  At that age, bigger is better and
too big is still not enough!

But if I ever find one now I will surely buy it for nostalgia sake.
(oops, I thought I was posting this message to boatanchors!  Nostalgia is
relevant to solid state, too!).

So I cast a strong vote to include data on the Power Mites in a future
edition of Chuck's Schematic and Internet Entertainment Gazette!

On a serious note, I would like to compliment Chuck on his schematic
compilation.  I would like to offer a suggestion for the future.  I think
that if available, the manual page(s) showing drawing or photo of the
front and rear panels, or side if appropriate, should be included.  These
are valuable in aiding identification of used rigs, id of controls,
connectors, etc.  I, for one, have been out of the hobby for a while,
and don't KNOW a lot of today's commercial rigs by sight.  And the
panel views are very useful for a variety of reasons.

Hi qrpers, I just put together the kk7qrp tx (73 Magazine)that was intended
for 80 meters.
I put it together on 40 though, and it works great.  I had a minor pileup
when I first called cq on 7.040 last evening. My first contact was in MD
from my qth in Brockport, NY. My report was 579. He was using an ARK 40.  Anyway, all the parts but the torroid were available locally (my junk box) even the output transistors (4) 2n3904 transistors in parallel.  This transmitter gets about 1.5 watts output on 40.  73  Brad WB8YGG

Yes, believe this is primarily confined to the LEO RS series, in fact there
seems to have been a flurry of articles in QQ within the last year on this
subject, most recent in the July issue. Works ok with simple antenna's
near as I can tell, unfortunately I can only work them when my line noise
drops low enough on 10M that I can hear weak signals.

I also seem to remember that the OSCAR series satellites have qrp
days but what that means I'm not sure.

Ni-Cad Notice # 1..

Ok, several weeks ago, I purchased a bunch (approx 3 dozen) of Govt
surplus Ni-Cad battery packs.  Each pack contains 20 each D-size
Ni-cads.  The individual cells are wired in series/parallel to produce
several outputs.  The packs are in a metal case and include a circuit
that displays the hours of charge left, when the switch is pushed!  I
have disassembled three of them and found all batteries to be good.

Frankly, I am tired of tripping over them... I will let them go for
$10.00 each, plus shipping.  Any takers?

The first mention of 72 that I saw in print was a guest editorial by Gus G8PG
in SPRAT #68, Autumn 1991. He says that there had been a suggestion some
months before by members of the U QRP club that QRP ops use 72 to mean
"Wishing you Good QRP". It was adopted soon after that and I have heard it
used a lot between QRP stations, especially in the ARCI contest.

Hi all, Sorry about forgetting the date of that article.. it was in May 1991
of 73 Amateur Radio Today.  There are two Transmitters there , one the
40 meter wave bender and one the Color Burst tx (73 mags version) .  Anyway,
I etched both boards using the QST method of July, 93 (pg, 42). I assembled
the colorburst Tx with the 40 meter output filter, and I also used a 7805
regulator for the 5 volt supply instead of the two 6 volt batteries, I use
my one 12 volt supply.  Someone asked if this was available at a ftp site,
but it's not, only because I'm not sure of the legalities.  Anyway, I think
this is a lot easier to get going than the Cubic incher that I made for 80,
 and most of the parts are at Radio Shack. Anyway, Happy Building, and
maybe I should call Wayne Green to see what kinda fit he would have if we
put the artwork on a ftp site.. 73/72  (I'm slowly converting to use of 72).

Swami mentions that he can't hear W1AW on 20 meters.
First, even if our antenna were pointing your way,
you're too far for ground wave, and too close for
sky wave. You're in what's known as the "skip zone."
This is not to be confused with the Twilight Zone,
which is where ARRL Hq is often accused of being.
See _Now You're Talking!_; I think we covered the
skip zone there.

On 80 and 160 we use wire antennas close to the ground,
for local coverage. On 40 and up we use yagis pointed
NW, so you're behind the antenna anyway. You'll have
to listen on 80 (3581 kHz) or 160 (1818 kHz). QST had
an article on a crystal controlled 80-m receiver for
copying W1AW, that used a 3579.545 kHz color burst
crystal in the local oscillator (LO). I haven't tried
it. Living 1/2 mile from W1AW, I pick them up on my
refrigerator, electric tooth brush and the hallway
light. I can always tell when I'm late for work: W1AW
goes on the air at 9 AM Tues-Fri. If the hall light
is pulsing, I know I have to sneak in the back door.

I don't know of any other QRP nets on 20 meters. There's
a County Hunters Net on 14065 (?) during the day, I
think.

Good luck, 72/73---

Just curious, are there very simple ways to get a rough estimate of
swr for my little mini antenna tuner?  I plan to take my Spider to
Arizona, and have built a tiny Z-match, and wonder (don't have a small
swr meter to take) if I can play games with an L.E.D. or something
to try to pull down swr on a random wire without major work?

Message-Id: <[e-mail]>


Gang,
   Radio Shack has one of their CB's (blah) on sale for $40. It is so
tempting to get one and try to put it on either 10 or 12 meters CW.
But I've heard that it is next to impossible to do anything with
the PLL generated frequencies. Can a transverter be built and placed
before the final amp? Say mix a 1 mHz oscillator with the synthesizer
output to give the amp a 28 mHz signal (filtering out the 26 meg signal).
Or am I in dreamland even considering such an idea...

Jeff, NH6IL

Subject: converting CBs

Jeff NH6IL wrote commenting about a CB at Radio Shack for $40 and how it
would be neat to convert it to 10 or 12 meters.  During the late seventies
73 magazine had abunch of articles on converting CBs built with a type
of mass produced board to 10 AM and FM as well as 10CW.  I believe I also
saw an article on converting one to 12 meters not too long ago.  The boards
were built by a Japanese manufacturer and were used by Kraco, HyGain and
Midland in several of their radios.  You can get these radios for next to
nothing at flea markets.  I've got several and usually give between
$1 and $5 for them.  I've done the 10FM conversion and even worked
Seattle with on (5 watts mobile!)!  If you guys are interested I'll post
more info on what models to look for and where the articles (month year)
are at.

QRP QSO Party exchanges are usually given in the
contest announcements in QST and CQ.

There is no set exchange for the First Sunday
event--it's just a chance to meet other QRPers.
If you have club numbers from QRP clubs, you'll
probably exchange numbers with the people you
work. Otherwise, just say "HI."

Subject: Project 3: 80M xmtr with VFO
Cc: [e-mail]




Hi Gang:
   An opinion from someone at our law school is not to worry about
any copyright violations; email me for full details.
   This week we have an 80 meter 1/10 watt output xmtr with a VFO!
Not too many of us still have a drawer full of xtals (gave all my
away when I sold my DX-60).
   Construction is pretty straightforward. C5 is the VFO-frequency-
adjust control, while C4 acts as a preset calibrator. Output is
governed by setting of C9.
   It is most important to shield the VFO section entirely (including
Q1); this will prevent hand capacitance from pulling you off frequency.

Oi!!!  Got any mods to convert older CB's to 6 meters.  It seems to me
that I saw an article in one of those 'Illegal CB books' (gasp) :) .

Every ham should buy all the old SSB/AM CB's they can, and sit on them
so the CB'ers can't use them for their illegal activity.

The FCC (one of the rare times I wil praise them) has made manufactures
of CB's use more 'touchy' PLL's...

Subject: converting CBs

Gang,
    There are many CBs which are modifiable to ten FM, AM, SSB or
for use on CW.  There are also many articles on the subject.  There
are a few personal favorites I have so I'll stick to those.  Actually
any CB can be modified for use on Ten... it just depends on how much
trouble you're willing to go through.  Now I'm a fairly lazy type of
person and try never to overextend myself.  In other words, the CBs
I convert have to be easy to do AND inexpensive.  The two types of
conversions I've done are moving an AM CB to Ten FM and moving a
SSB CB to Ten for SSB use.  The conversions to Ten FM can also be
converted to Ten CW for even less.
    The Ten FM conversion requires one crystal, an FM detector board,
several cuts and adds to the CB board and a realignment of the CB.
The same conversion to Ten CW could be done with one crystal, a
455khz BFO oscillator, several cuts and adds to the CB board and a
realignment of the CB board.

Here is a list of AM CB radios that are excellant candidates for
either conversion:

Manufacturer    Model         Manufacturer    Model
Hygain          #1A           Lafayette       HB650
Hygain          #2A           Lafayette       HB750
Hygain          #3A           Lafayette       HB950
Hygain          #4A           Lafayette       Micro 223
Hygain          #9A           Lafayette       Micro 223A
Hygain          2681          Lafayette       Comphone 23A
Hygain          2682          Lafayette       Telsat 1050
Hygain          2683          Pierce Simpson  Tiger 40A
Hygain          681A          Pierce Simpson  Tiger 23 MkII
Hygain          682           Midland         13-882C
Kraco           2310B         Midland         13-857B
Kraco           2320B         Midland         13-888B
Kraco           2330B         Midland         13-830
Kraco           4010B         Midland         13-955
Kraco           4020B
Kraco           4030B

There are probably many others available, but these are the ones
I know about.  The most important thing to look for is inside the
radio (don't forget your screwdriver!).  In each of these radios
there should be, just behind the channel selector, a PLL02A chip.
If the radio you're looking at doesn't have this chip, don't buy
it.  This is the easiest board to convert.  (Gosh I feel an article
coming on!) <g>...
More later !   Mike KE4PC

Subject: NorCal QRP Club Report

     The August meeting of the Northern California QRP club was a resounding success.
More than 30 members attended, several new members were signed up and it was
a very enjoyable morning.  Jim, WA6GER had several of his rigs there, including
the OHR 30 & 40 meter rigs, plus his favorite, the "Spider" (By the way, he has
9 states worked with the Spider, and that ain't bad with crystal control!  Mike
Collins, KC6SEG, wasn't there (he's working in Alaska) but his "Ugly"
transceiver kit was, and it is anything but "Ugly".  It is  a kit that Mike put
together and since I sold him the kit, he let me use it for a few days while
he is in Alaska.  The rig is a 40 meter transceiver and comes from an article
in June 92 QST, or the 92 or 93 ARRL handbook.  It is vfo controlled, direct
conversion receiver, and puts out about 2 watts, with variable drive.  Mike got
the parts from me, ordered the boards from FAR circuits in Ohio, and put it in
a beautiful aluminum cabinet.  The rig turned out absolutely beautiful and
everyone who was there oohed and awed over it.  If you see Mike, let him know
that his rig was a hit.
     Jim Pepper, W6QIF, who has an article coming out in the next issue of
Communications Quarterly about his 40 meter transceiver was there with the rig.
It has "digital readout", and is another beautiful piece of work.  Jim has
agreed to let me reprint the article in QRPp, the NorCal journal, as soon as it
comes out in Communications Quarterly.
     Hollis Button, WF6U, didn't make it this month in person, but I had his
picture there.  He is on the cover of the summer issue of LowKey, the Australian
QRP journal.  Congrats to Hollis, and if you see him before I do, tell him that
I want his autograph on my copy of LowKey.
     I also would like to announce that Jeff Jones and I will be doing a session
on QRP at the Pacificon Convention.  Don't know for sure when it is scheduled
for, but I will let you know when more details are available.  Basically, Jeff
and I will be displaying various pieces of QRP gear, magazines, journals, and
singing the "praises" of QRP.  Hope you can attend.
     The second issue of QRPp, the Journal of the NorCal QRP club will be
printed and mailed the 1st of September.  Here is a rundown of what is coming
in the next issue:
1. Whither thou goest Norcal?  WA6GER writes an excellent article on the future
of the club.
2. A member profile of Wayne Burdick, N6KR.  Get to know more about the designer
of the club project.
3. Announcement and discription of the NorCal 40, a cw transceiver that will

Guys, I am posting this as several of you have made contributions to the
journal.  Each of you who wrote articles will be receiving a complimentary
copy of the journal.  This issue is 44 pages right now, and will be sent
to the printers when I return from vacation in 3 weeks.  Have a good time
and think of me in Toto Land (Kansas).  CUL, 72, Doug

Subject: Dan's Kit


i got my 20 meter kit from Dan's Small Parts and Kits on Saturday
and got the boards assembled on Saturday.  great kit.  here are
a few notes:

1.  make holes larger for mounting pins on 7MM 10.7 MHz cans

2.  predrill mounting holes

3.  move couple of lands away from board edge where standoffs to go

4.  move Y1, Y2, Y3, and Y4 farther apart on board for mica caps in
    Cohn Filter

5.  0.01 uF cap missing from Q4 to Q5 on transmitter board on pictorial

6.  0.005 uF from pin 1 of LM386 is shown as 0.001 in pictorial

7.  pictorials don't show cathode ends on mounted diodes vertically mounted


The pictorials that i refer to above are the additional stuff that Doug,
KI6DS, has that NN1G provides.  Those of you who got Phase One of the
Schematics have the three page article in QQ.  Add 100 ohm resistor
from base of Q7 to ground.  Same as in the MFJ diagram.  L4 should
be 11T (not 4 as shown in schematic).  Parts list is correct.

I have mods for 40 meters and will put them in Phase Two.  I'm in
collecting mode now.  HINT. HINT.

Ed P.?  what is the internal cap on the 7MM 10.7MHz FI Xfmrs?
if i don't find them by monday noon.  tnx.

i haven't fired it up yet.  doing the mechanical work on the chassis
at the same time i'm doing work in garage and yard...... ;-)  darn
summers in texas......

didn't hear any of the gang on the qso party, but i was outta pocket
again most of the time.

you guys and girls have a good week.  send SASE to
Dan's Small Parts and Kits
1935 S. 3rd W. #1
Missoula, MT  59801

nice prices.

SASE's to Dave Benson, NN1G, 80 E. Robbins Ave., Newington CT 06111
for info on xcvr and FAR Circuits, 18N640 Field Ct, Dundee, IL 60118

p.s.  someone last week resigned from list.  someone from EU, AK, and
other continents please jump in here.  you guys and girls south
of the equator, make us feel bad because you're enjoying 40Mtrs
during your winter time!!  how's DX?  what kits, projects, do you
have going?  the group wants to know.......

Subject: I worked RS-12!

After reading the article on QRP satellite communication in the new
QQ, I went up to my shack last night about 10pm EDT.  I have no
tracking software so I was just listening on the beacon frequency to
see what I could hear.  Sure enough, I could imagine that I could hear
the beacon in there on 29.40872.  As I listened it got stronger and
stronger.  Tuning up the band I discovered 5 or 6 CW signals and 2 or
3 SSB signals calling CQ RS.  Some of these signals were hitting S-3!

I put my Ten-Tec Paragon in split mode, transmitting on 21.230 and
listening on 29.430.  (No way to hear myself with only the one GAP
vertical antenna).  I turned the power all the way down and responded
to a CQ from N4ZC.  He came back to me!

I worked Mount Holly, NC from Apex, NC (maybe 200 miles) via RS-12.
Switching to the input frequency I couldn't quite copy his up signal.

Anyway, I got a new kick from my first satellite contact.  Gotta send
Roger a QSL.

If I remember correctly you said that these were out of an old book.
In the august QST they said to be careful of old articles because
the circuits may not meet current FCC signal purity requirements.
See august QST for the full details. I don't know if this circuit
meet's the standards or not It's just something to consider.

Remember, I make no claim as to the performance of these VERY low power
transmiters. It is every amateur's responsibility to insure that his/her
transmitted signal meet all legal standards. We are supposed to monitor
our signals with the proper test equipment. `Builder Beware!'

Subject: QRP calling freqs

Chuck posted this a while back -- MI QRP June 1993 pg 11 fills in the
gaps on 17 and 12m. I also add suggestion at VHF of using the National
calling frequencies as this is where you'll find the most of the weak
signal guys listening.

here is the list, as i have it for the internationally recognized
QRP calling freqs +/- QRM......

BAND    CW        SSB

160M   1.810MHz   1.910MHz
       1.843MHz             (Europe)

       3.710                (US Novice)    don't forget about these guys.
       3.579                (Colorburst TXes)
 40    7.040      7.285
       7.030<-->7.060       (Europe)

Cc: [e-mail]

I send away for info on the HT-750 and got a Japanese flier
with some english translations splattered about.  The price is
$599 for the unit, $13 for the base ant., $35 for the 7 Mhz coil,
$24 for the 21 Mhz coil, and $16 for the 50 Mhz coil.  It seems
you must change coils if you change bands.
40m is 7.0 - 7.299 Mhz
15m is 21.0 21.499 Mhz
6m is  50.0 - 50.499 Mhz.
Only takes 8 AA batteries (Ni-cd's are ok)
Current Consumption 100ma Rx, 1.5 Amp Tx (max).
Weight: 1.8 lbs with batteries.
Rx Type: Single Conversion
Rit coverage +/- 0.5 Khz
Audio Output : 0.8 watts (with 10% distortion)
BNC-type Ant connection.
Separate Mic and speaker built in (with separate jacks)
CW Keying connector
Separate DC power plug (but you must switch between battery or external)
RX pre-amp is switchable on/off.
Frequency Lock switch.

(in addition to what was listed in the first message )
It seems like a lot of money for SSB/CW on three bands.  And I didn't
like the layout of the HT.  The company is selling these through
dealers.  You can
write to Orion Business International, Inc.
360 W Bedford Ave. Suite 111
Fresno, CA 96711
for the flier.

Subject: QRP Calling Freqs

The problems with WARC band calling frequencies continue.
Kevin was polite enough not to mention it, but I got
chastised for not doing enough research to list them
in "Low Profile Amateur Radio," which was reviewed in
the latest _Five Watter_.

Referring to Chuck's earlier posting on the subject,
you'll see that the Europeans use different calling
frequencies. On 30 meters, the West Coast is using
10.123 MHz, which is unusable in Europe. Thus, I
decided to leave 'em out. Besides, sooner or later
you have to jump in and work the QRO guys, which
means leaving the nest and entering the battlefield.
Most of the time, it's easier to work the QRO stations
anyway. They have stronger signals and usually have
better antennas, so they can hear me better! :+}

Subject: Phase 2 - schematic update



Gang,

sorry for the previous posting that had no text.  kinda a depressing
event.  spent some time typing it in and must have inserted some
control character that blew away the text.  bummer!

again, but this time i'm creating a file and then posting the file.  :-)

i've not been taking orders for the phase 1 schematics.  i will again, but
not now.  i have to get together more than 15 requests to get the costs
down to a reasonable level -- you know, setup, etc.

what i'm calling phase 2 has now started up.  contributions welcomed.

i received nice letter from Steve, KA1LM, and schematic for the TenTec
PM2/PM2A.  one page schematic and the manual, which 20 years ago when
the rigs were simple, of about 4 pages at 8.5x11".  thanks Steve.

here is what i have so far for phase 2 ------

1.  OHR Sprint
2.  OHR Spirit
3.  OHR WM-1
4.  OHR Capacitor Audio Filter  (thanks to Dick, KE8KL, for permission)
5.  TenTec PM2/PM2A
6.  TenTec 525D
7.  NN1G updates to '72' 20 Meter XCVR from Jan '93 QQ

contributions for the next group is now being accepted by yours truly.

some have volunteered back articles from QST, 73, HR (Ham Radio), and
others.  let me know in advance before you send them so as to avoid
duplication and a lot of work.......  don't know how far back to go.
remember, FCC regs and requirements on spectral purity have changed
and some of the old rigs won't meet or exceed today's requirements.

historically, i would guess we shouldn't cut them out as it would
be nice to see the 'good ole days' and the way things were.

remember, we're looking at $10 for 200 pages (100 sheets front and
back).  we can go higher, i don't mind but then again i don't know
what your budget is like.

feedback appreciated.....

for the DX crowd.
1.  explain to the US crowd what the SW Broadcast interference is like
    in Europe and other places.
2.  how is propagation south of the equator and QRN levels this time of year
3.  do you see much US manufactured equipment (like TenTec)?
4.  where do you typically obtain parts, kits, etc.

inquiring minds want to know.

also, as a side note.  this author is a native Texan.  don't blame
Americans for my lack of knowledge of the English language.  i am who
i am........

back to net control.  Bruce, you still there?  how is the list doing
and you might want to update the group as to how many on the list now.
ratio of US to DX?  are we generating too much traffic?  again, our
thanks to Thinking Machines (did everyone see them in Jurassic Park?)
and their contribution to a system mailer for this group.  good show!!

everybody take care,

(Putting on my "official" hat:)

I would very, very strongly suggest leaving out any articles
from these magazines, unless you get written permission for
each and every one. CQ Communications owns the rights to
Ham Radio magazine material now. I know to you guys this is
just a hobby, but it's some people's livelihood. Chances are
you'll get permission if you ask, but this is not a case
where "it's easier to ask forgiveness than permission."

Specifically, the company for which I work has published
its own anthology of QRP articles, "QRP Classics." It sells
well and makes us a few bucks every year. I don't think
management would look kindly on anyone who did an end run
and started publishing copies of our articles without
permission, even if you're giving them away at cost (or
_especially_ because you're giving them away!).

Our charge for photocopies is $1 a page, $3 for an article.
I don't know how much we figure is royalty money, if any.
I do know we will not copy from anyone else's magazine.

I hate to dash cold water on Chuck's project, but I'd hate
to see anyone get snarled up in litigation over copyright
violations.

Jim Kearman, KR1S, makes a good point and one that i'm sure
i don't want to cross over on copyright infringement.

at the present time we have available:

1.  ARRL's "QRP Classics" still in print and a good buy
2.  Doug Hendricks's reproduction of the QQ for $10/year

maybe we should stick to just schematics for rigs no longer in
production or for which i have permission to reproduce.  the
function here is to provide valuable information for buyers of
used equipment, for which the manual(s) are no longer available.
it is also a source of info for the experimenter at home.

Jim, i don't consider your remarks as 'dashing' cold water on my
project.  i'm not wanting to get myself or anyone else in trouble.
i support the ARRL with my membership (which i want to keep) and
have purchased your books as well as others.  keep up the good
work.

i'm trying to stay within all bounds of the laws, both local,
state, and international.

thanks to all involved,

Besides, I already have the ARRL stuff.. :-)

Does anyone have a good pointers or other info on a frequency
stabilization technique called "huff and puff"?  I've seen
references (G-QRP), but not a full circuit.

Subject: Huff and Puff

"Huff and Puff" was developed by a PA ham, I believe, and
was popularized in the Technical Topics column edited
by Pat Hawker, G3VA, in _Radio Communication_.

The H&P circuit is hooked across a VFO, via a varicap.
While you're adjusting the VFO, the H&P circuit is
idle. When you stop tuning, H&P looks every once in
a while to see if the VFO has drifted from wherever
it was when you stopped tuning it. An error voltage
applied to the varicap pulls the VFO back on frequency.

The add-on circuitry had evolved to CMOS logic the
last time I noticed, but was still pretty intense for
the application. I suppose if I was multiplying a VFO
18X or 24X, I might have to consider something like
this, but for VFOs in the MF/HF range it's unnecessary.
Using -6 or -7 cores, NP0 capacitors, double-bearing
variables and reasonable care in layout and assembly
gets excellent VFO stability. The H&P circuits were
not intended to cure the legendary drift of the
Heath VF-1; they were designed for short-term drift
of a few hertz, which is precluded by good design
and construction anyway.

Yes, I can provide references, but not at the moment,
as my notebooks are at home. I cannot provide
photocopies of RSGB material. Back issues may be
available from them, though.

Gang,

just had to report activity last night on 40 meters.  it was hopping
for this time of the year.

with the OHR Spirit running 2W out i worked DJ7AA near Hamburg, Germany.
goob op going at high speeds and slowing down for the slower ops.
my great circle bearing program gives me a total distance of 4,301 miles
or 6,927 kilometers.  thus i'm up from 1,488 miles/watt to 2,140 miles/watt.
he was 599, i was 439 RST.  i had to repeat, but it counts.  i'm in the log.
QSL going via buro.

also heard but no attempt to work were XE1CCB, VE2XLT/QRP, YU1QL, VE6NTY,
and a multitude of others.  ooops, i lied.  i did try YU1QL, but he
attracted a crowd of KWs...... ;-)

DXCC looks possible with 2 watts on 40 meters QRP.....

My HW-8 Goes To The Picnic

by Jim Osburn, WD9EYB

Saturday was the annual Wabash Valley Amateur Radio Association picnic
and the North American QSO contest.  Thinking this would be a good
opportunity to operate QRP from the park where the picnic would be held
and to have a lot of QRP QSO's and to work a lot of states, I made
plans to take my HW-8 to the picnic.

I have a 15 m dipole already to go for portable operation but I haven't
heard much on 15 m lately.  So, I decided to build some more antenna's.
20 m would probably be hopping during the contest so I had to have
an antenna for 20.  But, since 20 might suffer from bad propagation,
I decided to build a 40 m dipole too.

Friday night I built a 20 m dipole and a 40 m dipole.  My construction
wasn't fancy, just some dog bone insulators and some wire.  I attached
50 feet of RG-58 coax directly to dipoles without baluns.  My center
insulators were some glass insulators that I purchased at a hamfest
awhile back.  On the ends of the coax I attached PL-259 connectors.
I have little trouble soldering the PL-259's.  I have a huge soldering
iron with a one inch diameter tip that has no trouble at all heating up
the connectors.  You've got be quick though, too much heat and you have
a short.

The contest started at 1800 UTC Saturday, 1 PM local time, but I didn't
arrive at the park until the contest had already started.  I put up
my new 20 m dipole.  I had some good help from one of the WVARA members,
Mike, KA9OKO, in getting my antenna up.  Rather than taking the time to
trim the length, I used a transmatch.  I don't have a SWR meter with
enough sensitivity to be operated by the HW-8, so I used a noise
bridge set to 50 ohms and adjusted the transmatch until I got a null.

Shortly after 1900 UTC, 2 PM local time, I was on the air.  I had 8
QSO's in a little less than an hour.  I worked Georgia, Massachusetts,
Texas, New Mexico and Colorado.  It was very easy.  I would tune in
a loud contest station calling CQ and I would answer him.  They all
came right back and gave me my report, which was name and state,
no signal report, which in a contest would have been 599 anyway.
I would then give my report and that would be it, into the log it goes.
I didn't reveal that I was QRP, I might send them QSL cards to let
them know that 1.5 Watts works well in a contest.

I did spend some time answering an Oregon station.  He was fairly faint.
But I couldn't get him to hear me.  If I had more time I probably could
have got him, but I had other picnic duties to perform and had to
leave the contest after a little less than an hour.  I also didn't
get to put up the 40 m dipole.

Anyway, I had a lot of fun.  I highly recommend taking QRP rigs to picnics.

Gang,

In the Jan '93 issue of The QRP Quarterly, there was an article
by NN1G, Dave Benson, on Rick Littlefield's qrp rig, the same one
used by MFJ in the 9020 rig.  Then someone on the net came up with
Danny Stevig's new address and the fact that he has a kit for $49.95
that has the two boards and all the components on the board and the
air variable cap and the variable pot.  For that kind of money i
had to order one.  ;-)

Got it in short order and had it assembled in about six hours and in
one of my cases.  I wrote up some corrections that i have sent to
FAR Circuits (Fred does the boards), to Dave so that he can send
and pass on suggestions to those who order his plans, and to Danny
so that he could change the kit a little.  Just minor things that
will make sure that first time builders won't have too much difficulty.

I'm even writing a two page assembly manual just for the first time
builder.  I must have the urge to be an author...................

Well, i got the little rig fired up Saturday morning, since i had a
11am lunch meeting with the North Texas QRP Group.

Notes:

o  NN1G 20 meter transceiver kit from Dan's Small Parts & Kits
o  Rick Littlefield rig modified.  Similar to MFJ 9020 qrp xcvr.
o  single conversion superhet receiver
o  single band rig available for 40, 30, and 20.  the 30 meter
   version sometime soon.
o  Dan kits it with separate bags set up for several sections
   of the receiver and the transmitter
o  Cohn crystal filter for 10MHz IF, about 600Hz wide.  I
   listened to pileups on 20 meters today for the NA contest
   no problem
o  two boards, both 1.8x3.8inches, Dave Benson says put 'em back to back.
o  7mm IF cans
o  keep your #11 Exacto knife handy, you will need it to cut the
   internal capacitor out of some of the IF cans
o  you wind 8 toroids, not difficult
o  rig is QSK!!!!  my favorite part
o  vfo controlled, but no RIT
o  has place for agc, but not circuit at this time.  i'm looking at
   the mfj design to see how hard it would be.
o  1.5W out using 2SC799, which i understand is not being made anymore,
   but someone on this group can give us an exact or better replacement.
   Dan has plenty of spare parts.
o  quality of parts in kit is nice and it comes with the 8 pin sockets for
   all the ICs (5 total) 3xNE602s, MC1350 IF amp, LM386 AF amp
o  no assembly instructions except for pictoral of parts layout for
   both boards
o  i've been playing with mine into dummy load the the keying is
   great.  smooth, sharp, crisp, and chirp free.
o  output low pass filter is five element Chebyshev
o  kit has both boards, all parts on the boards, air variable cap,
   volume control with on/off switch.  you'll need box, phone
   jack, power connector, ant connector, knobs, .... most of us
   have this stuff in junk box or we can get it a local Radio Shack.

i think somebody(s) has one on the net besides me.  was that you
Doug (KI6DS)?  how is your's doing?  got it assembled yet?

i haven't transmitted with it yet live on the air.  i've gotten
it aligned and listened to 20 meters for some period of time
checking out the receiver.  used the OHR WM-1 wattmeter to show
that the transmitter is putting out 1.5W into 50ohm dummy load.
using the TenTec Argosy II receiver, the 20 meter kit has a clean
crisp note and NO chirp.  one of the cleanest signals for a kit
except for the OHR rigs and MXM.

i'm in process of checking it out with other rigs, since i only
have two rigs capable of transmitting on 20.  all the other monobanders
are on 40.

Kit $49.95 from Dan's Small Parts and Kits, 1935 S. 3rd W. #1,
Missoula, MT  59801 and $3.75 for shipping.  I don't get a dime
from Dan, just another satisfied customer.


Hope we don't put him in overload.  :-)  I had Oklahoma QRP group
sked on Sunday, 8:30am CDT, and one of group already had one and four
others were ordering.  May take off like a rocket on sales.  :-)

Speaking of, I ordered the CMOS Memory Keyer II.  Got card from R&R,
14 day delay.  Guess Doug's posting created rush of sales.  All this
economic power in one place.

FT8WA is quite a good catch on 40m, especially with only 2 watts. I was on
40m CW earlier last night but did not hang around long enough to hear him.
My only confirmed Crozet contact was made on 40m some time ago.

Subject: Sudden RX for 30 meters.

Hi all, I finally got my sudden receiver for 30 meters going a couple of days
ago, and I was wondering if anybody else on the net had built this particular
version of it?

I had some problems getting the thing to oscillate with the caps mentioned in
the text from 73 magazine.

Then last night I saw a packet request for help on the Sudden for 30 meters.

Sounded like the guy was having the same problems I had experienced.

Anyway, I forwarded my fixes to him, and I was wondering if anybody here wanted
to compare notes?

P.S. I made my first contact with the Sudden Rx and the Ramsey Transmitter that
I bought for $15.00.  Tennessee from Upstate NY and 1 watt.  Who says HF is expensive.

I have one - will try to get it built this week, between testing a
board for Nov 73 magazine and trying to get my 8051 controller up.
Will let you know how it goes - I plan to put mine on 40M.  Also, I'm
going to hook it up to the TW1 DDS and see just how much range I can
get with this setup - I've been told that the VFO only gives about
30-50KHz on 40 as it sits.

One of our locals, WA9QMO, also has one he built from the article and
the boards.  He's waiting to get it aligned (soon as I can send him
the instructions from Danny's kit).  Will let you know how it runs,
too.

btw Chuck - I was at Fred's when he got your letter *and* Danny
called, ordering another dozen boards.  Fred will be drilling those IF
can mounting holes a bit bigger, and Danny's sending him the parts
placement drawing so it can be silkscreened.  Will be *much* easier to
build then.

Since all of you have gotten the kits from Dan's, is he
going to have any available for 30 meters.. I have the

Gang,

i got questions from one of the members of this group, so i thought
that i would respond to all.

1.  the kit from Danny is complete for the boards and the parts on the
    boards.  there were no wrong parts supplied, but the silver mica
    caps were too big to cosmetically mount nicely between the xtals.
    this has been fixed.  you will not need a supply of parts unless you
    want to build it for 40 meters.  see later.

2.  the kit comes complete with two circuit boards and all the parts that
    mount of both.  it does have the air variable and the volume control
    pot.

3.  there are no knobs, dial indicator, power connector, case, key jack,
    phone jack, or rf power connector like a PL-259 or rca jack.  these
    you have to provide.

4.  the rig is sold as 20 meter version.  they are working on a 30 meter
    version (Dave NN1G).  for the 40 meter version you need:
    a.  wind a few toroids differently, but this is no problem and you
        have enough wire to do it, if you're not too sloppy.
    b.  you will need caps of value 47, 47, 5, 5, 47, 47, 330, 680, and
        330 pF.  they do not have to be NPOs.

i know that some people will probably go and bang on Danny to supply
the parts, but there is a limit to what one can supply and not lose
money.  let's keep him in business.  you could order 10 each of the 5
and 47 pF and pay $1 per 10, thus an additional $2 will get you most.

i don't see disc caps for 330 and 680 in the catalog, but will let
you know if i find out anything.

hope this helps.

5.  i don't have a comparison of this rig with the A&A, as i sold it
    several months ago.  i like the NN1G kit (i guess i need to call
it 72 Kit, as i think that's its name in the QQ) better as it is QSK
without relay.  the A&A uses a relay.  i'd guess the 72 is better.

    the OHR Spirit is a better rig all round, but its $200 price tag
may drive some people away.

Joe, KI3B, mentioned that 40 meters was getting harder and harder
to find a spot below 7.050 to do a qso.  i agree.  it's gonna get
worse.  i think that we need to start working 7.040 and up and
put the squeeze on the digital guys to move up another 10KHz.  i
don't have an answer for this one.  use it or lose it is my motto.

:-)

ok, let's stir up the activity on this qrp group again.

i'm going out to watch the 'shower'.  hope that Ed and Zack get
some scatter up at 10GHz and above.  you guys and girls on the
east coast let us know if you got a good view.

Hello to all-

  I found a dark spot in the country and watched from

More like a drizzle than the shower/storm they predicted!

  The 6 meter band was fairly active here in en82.  I worked
k1tol in Lewiston, Maine (fn44) via scatter using 10 watts.  An

Subject: meteor sprinkle in Upstate NY


Well, I too was out with my family from about 9:00 to 10:30.

My wife saw a beauty of a meteor with a red dotted trail as she described.

The rest of us saw many firey ones, but they tapered off after 9:40 or so to

just the bright ones with whitish tails.  All in all we saw about 10-15

meteors and probably 20 satellites go over while watching.  There was just

enough clear viewing right overhead to see some..  73

2M SSB was very busy last night. Many stations were on trying to work meteor
scatter. I heard 3 stations around 0300z in the following grids:EN34,EN35 and
EM31. Signals were weak and the local QRM was tremendous. Lots of space on
VHF don't know why they don't spread out more. There was also a very good
tropo opening to the south and I worked WA2TOP in FM25 , Cape Hatteras from
my QTH in FN20 in Northern NJ. I was using 4 watts PEP into a 7 element
yagi. He was using 10w PEP into 11 ele. Stations in FM26 were also worked
QRP on 2m and 432MHZ. They meteors were much less than everyone expected
with all the hype beforehand. Kind of like Halley's Comet...

Gang,

i went out over 40 NW of my "ranch" to a dirt road NW of Krum TX.
population 200!  dark sky.

i saw about 40 the first hour 9-10 then a real good run starting
at 10:20 to 10:45.  then almost nothing, so left at 11:15CDT and
back to ranch after midnight.

about 15 good fireballs and some faint trails about twice diameter
of the moon.  if people are not where it's dark, they will miss these
'minor' meteors.

i went out in a pickup truck and used lounge lawn chair to sit back
and relax.  since i was going to be out a couple of hours, i took
the 20 and 40 meter WD4BUM antenna sticks and the 72 xcvr and the
MXM 40 meter xcvr.  thus, i was able to listen to the bands and
watch at the same time.

20 meters was dead except for a couple of weak stations and W1AW
bulletins.  40 meters wasn't all that busy either.  guess everybody
was out watching.  heard some VE's and CO's.  heard more than the
usual amount of W5s, which meant that the band was short for a while.

in all, about 65 meteors and some CW in the same trip.  i forgot the
keyer and wasn't thinking that i could have worked anything at the
same time.

during this whole time not a single car went by me on the road where
i was parked.  temp about 84F with slight breeze.  not bad and NO
RAIN......

hope you did as well,

I saw four.
I watched from 0240 UTC until 0310 UTC.
(That's 9:40 PM until 10:10 PM EST, not EDT or CDT, this part of
Indiana is EST all year.)
I saw three big bright orange ones that left glowing tails.
I saw one white one that didn't leave a tail.
All were moving NNE to SSW.

I'm amazed that I saw any.
I came home from my sisters discouraged that conditions were cloudy,
hazy and light polluted, and it was lightning to the east.
I put the car in the garage and looked up on my way into the house.
I had to position a tree between me and my neighbors dusk to dawn light,
and my house between me and the street light out front, and the
garage between me and the other neighbors house light.
I could see only four stars, the cross in the constellation Cygnus I think.
I was thinking it's silly for me to be out here looking and that I should
go inside when a big bright orange one that left a glowing trail went
whizzing by.
It came from the NNE and went to the SSW, definitly a Perseid.
I about fell over with surprise.
I stayed out until the clouds started rolling in and saw three more,
all moving NNE to SSW, definitly Perseids.
I found one other ham on one the local repeaters who was also out looking
and seeing about what I saw.
I feel lucky.

Well, here is the story. I am going to work on an article
for December QST on Mobile HF (not just QRP..sorry). I have
come to conclusion that all information that is available on
about any ham question is in someone's brain that is on this
list.  I would value greatly any suggestions, comments and
experiences on this subject and:

1) wiring up a mobile rig(installation..brackets electrical
system concerns, paticular brand car problems.. like with
car computers)
2) mobile inteference problems
3) good hf mobile rigs and why
4) mobile antennas.. specs.. what is best and why.. personal
and quantitative info (not quoted from sales material)
5) rewards and pitfalls of mobile
6) operating tips
7) other stuff people are interested in reading.

I have a bunch of info and operate mobile/CW/QRP and
mobile/SSB/QRP.. but would rather have a broader input on
this subject.

The purpose of the article will to hopefully get people
excited about this part of ham radio, tell them enough
information about what is involved and give them insites and
personal experiences.. not going to be a real technical
article.

thanks

I've got the kit for the 72 xcvr, and started building it for 20
meters.  I got the first bag of parts for the rcvr done, and hooked it
up to see how well the VFO worked.

Straight out, it was at about 3.8MHz, and it was drifting fairly fast.
I let it warm up for a few minutes, (no air movement, no heat sources,
etc.) and it was *still* drifting upwards.  On a timed run of 5
minutes, it drifted up by some 350Hz, and was *finally* slowing down
after about 10 minutes of being 'on'.

Is this normal / acceptable?  Seems to me, if you're running CW with a
narrow filter, you'd have drifted clean away by the time you got a QSO
started.  Am I just being picky???

For a comparison, I hooked my DDS VFO up and did the same 5 minute
run, from a cold start.  Mine drifted 4Hz down.  Note: Not KHz, just
plain old Hertz.  Granted the DDS is a good deal more complex and more
costly, but I'm looking for *stability* here.  Maybe not NBS quality,
but better than a total of about 3KHz in 10 minutes from a cold start.
Additionally, I get the benefit of *knowing* what my frequency is from
a digital readout instead of analog dials.

Any comments?  72 es 73  -->jjw N9JZW

Contact Henry Radio.  They usually have an ad in the first few pages of QST.
Call them and ask the "front desk" for the Amateur Radio department.  Tell
them you want a copy of the service manual.  They will send you a copy for a few
dollars. Disclaimer: I have no relationship with Henry Radio other than the fact
that I own a Tempo S1 myself.

As long as we are discussing Tempo S1 radios, does anyone have any
interesting attachments or modifications that they would like to share?

Thats quite a bit of movement (+350Hz in 5 min. @ 3.8Mhz w/ no external
heating or air movement). With start up drift that high (basically due to
only RF current heating components) your probably going to have a major
problems when the boards are packaged in a box and you get bigger temperature
variations.

Without knowing anything about the parts provided with the kit, its impossible
to suggest a remedy  (but I'll bet your tuned circuit has capacitors with
to much negative temperature coefficient).

Ah! My first HT!!!  $350.00 from an Indiana dealer at the Louisville,
KY, hamfest.  He brought two of them.  My partner and I bought both of
them...  Found  rubber duckies before the day was out..  Used that
sucker for years... If finally quit transmitting.  Traded it to a
friend for some computer item.. He found that the contact from the
antenna connection to the board was bad.  Replaced the contact with a
BNC connector, bought a new rubber dummy load antenna and his son,
Chris, a 9 year old Novice, is still using the rig.  Other than that
mod, I think I replaced the battery pack about 10 years ago.  One of
those items I should have kept!!!

Anyone need the original rubber duckie antenna.  I think it is still
in the desk drawer, at home.

Earlier I believe I had posted (maybe I'm just dreaming) a
note to this group about Atlas Radio products.  Anyway,
Herb and Atlas Radio are still in business, and I just
received a blurb on their new Model 310 Radio, which is
normally a 100-watt plus transceiver, but is front panel
control reduced to 5-watts.  Just like information was
provided to this group earlier about Ten-Tec's Scout, let
me through this out to you.

Thanks.

Kevin Anderson

==========================================================
ATLAS Radio introduces....The NEW Model 310 HF Tranceiver
for SSB, CW, Packet and Amtor.
==========================================================

* Features DDS (Direct Digital Synthesis) Frequency Control.

* COVERS ALL 9 AMATEUR RADIO HF BANDS:  Transmits and
receives from 1.8 to 29.7 Mhz, and includes MARS and CAP
frequencies.  It will also receive all the HF Marine
frequencies, as well as short wave broadcasting.  (Note:
As a transmitter, the 310 is designed only for amateur
radio bands.  It is not type accepted for transmission
in the marine frequencies.)

* POWER OUTPUT:  150 watts PEP in SSB mode, 120 watts on
CW, 80 watts on Packet and AMTOR.  No transmitter tuning
is required.  Power is panel adjustable from 5 watts to
full power.  Rated power output requires 13.8 volts DC
at the rear power connector with full transmit power.
Lesser voltage will reduce power accordingly.

* DIGITIAL FREQUENCY DISPLAY:  7 digit readout to 10 Hz
increments.  Digits are LCD (liquid crystal display)
0.4 in. high, are back lighted for easy reading in light
or dark surroundings.

* STANDARD FEATURES INCLUDE:
   a) Break-in CW keying
   b) Upper/lower sideband selection
   c) PBT, Pass Band Tuning control
   d) Internal speaker, top mounted
   e) Noise blanker
   f) The DDS has dual frequency capability which
       permits separate transmit and receive frequencies
       anywhere in the band, as well as the advantages
       of RIT

* DDS, Direct Digital Synthesis, is a state-of-the-art
system for generating the injection frequency required
by the receiver front end mixer.  The DDS chip is a
product of Qualcomm, a San Diego, California company.
It provides an extremely clean and stable output to the
mixer, in both receive and transmit modes.  The mixer is
a Mini-Circuits component which assures high standards
of receiver performance.  Typical Receiver Specs:  .25
microvolt sensitivity, Dynamic Range: 134 db, 3rd Order
Intercept: 18 dBm.  There is NO PLL (Phase Lock Loop).

* SINGLE CONVERSION SUPERHETERODYNE.  The DDS LO output
converts the received signal to an Intermediate Frequency
of 9 Mhz.  A bank of 7 band pass filters provide more than
85 db image suppression.  Each filter has 9 poles.  Single
conversion provides superior performance to multiple
conversion, and enhances the KISS principle.

* SWITCHABLE CRYSTAL FILTER:  Standard feature provides
choice of 3 band widths:  2.7 khz for normal SSB, 1.8 khz
for narrow SSB in crowded band conditions, and 0.6 khz for
narrow band CW.  6 to 60 Shape Factor is 1.4 to 1 in the
2.7 khz bandwidth position.

* DC POWER REQUIREMENTS:  12-14 volts at 500 Milliamps for
receive, up to 22 amps for transmit.  Average with SSB
modulation will be approx. 8 amps.

* PHYSICAL SPECS.:  9 in wide, 3.5 in high, by 9 in deep.
Total weight, less power supply, 8 lbs.

* FACTORY DIRECT INTRODUCTORY PRICE:  $795

* OPTIONS:

Power supply Console for 110/220 volts AC, 50-60 Hz   $189
  (plugs directly into the back)

Deluxe Mobile Mount (into which the Atlas 310 plugs)  $ 69

Howdy:

I am chomping at the bit waiting for the NN1G 30 meter version......
AND just got notice that my R2 / T2 boards will be here soon :-)
so, finishing my Ph.D. this year should be a breeze (not!).  Ham radio
is too much fun.

Anyway, I am working on my new (old) OMNI-C to fix the receiver on
160...and I have it figured out now.  Some fixed capacitors in the
Rx trimmer board have gone south.  But my question is:  anyone know
how critical the alignment procedure is for the Argonaut / Ten Tec
receivers?  They indicate you need some good equipment, and that you
temporarily solder capacitors in on the trimmer board, then remove
it....and then bring up the signal and adjust....and stuff.  I wonder
if anyone has done that AFTER just plain doing it "by ear" and "s-meter"
and how critical does it look?  I plan to realign my OMNI, and I plan
to realign my Argonaut 509, pretty much the same stuff.  Just wanted
to know if I should try to get over to Gordon West's house to borrow
his radio lab to do this, or whether I can handle it adequately here
at home.

AND, I am, once again, impressed by Ten Tec service over the phone.
John McCoig helped me diagnose my problem over several days and calls.
He is gathering the parts for me now.  Nice stuff.  Also, once again,
I love the discrete components on boards - I can fix it myself if I
take the time.  Feels good to fix my own radio.

Many thanks to all who responded with help for the drift I reported
with the 72 xcvr.  Turns out the drift was not caused by a silver mica
cap, but by the MPF102 in the oscillator.  I changed caps, changed the
coupling cap, put some heatshrink over the diode, but the drift went
right away with a new MPF102 (my *only* spare).  Why this is so, I
dunno.  Maybe heating changed the gate capacitance?

Anyhow, just got it lined up and functional.  The analyzer shows 2
rather close-in spurs only 30db down, all the rest are 40+ down.  The
spurs seem to be from the bandpass filtering off the tx mixer.  Will
probably experiment some more to see if a change of capacitance helps.

I put a different tuning cap on, one I had lying around.  The unit now
covers from the high 13's to about 14.150MHz.  Pretty stable, though
the DDS still beats it.  It draws about 35-40ma in rcv, and puts out
2.24 watts on xmit (will measure current later).  I'll probably be
dropping the output power a bit, by adding a protection diode to the
power input jack.

The alignment instructions are a bit vague, but with a freq counter
and aspectrum analyzer I managed to get through it OK.  Had to change
tx mixer crystals though, to get the correct tx offset.

With just an LM386 (and the extra 10uF cap) into a decent speaker, the
volume is plenty loud, even for a noisy room.  It'll probably be
louder when I put it in a box.  (radio shack has a *nice* car speaker
for around $7-ish, with a huge magnet.  very efficient, and sounds
great.)

Will have Vikki let everybody know how it works once I get it in a box
(still a Tech, and don't much like CW anyway but she's an extra and
loves it).  Thanks again.  72  -->jjw

You only have two choices

Unload it at the next flea market or diagnose the problem and repair it.

With a simple RF probe (can build one w/ a resistor, capacitor and diode) and
a voltmeter you should be able to isolate the problem. Starting at the 1st
transmitter stage look for RF output. Keep moving toward the output until you
find the stage thats broken. Check for prober DC voltages. Now you only dealing
with a simple circuit and a few logical possibilites (e.g. shorted circuits,
open circuits, faulty parts etc.).

Since you dealing with a kit, that my not have even been assembled correctly,
this process will also cover that possibility too.

MSG#68 08/14/93  13:08:43 FROM K7YHA TO QRP
SUBJECT: Tejas Backpacker II-Review
The following are my observations and comments regarding the
Tejas RF Technologies new Backpacker-II QRP transceiver. My
review rig was a factory assembled 30 meter transceiver that
Bill Hickox, K5BDZ, sent me. The new rig differes slightly from
it's predecessor the BP-I. The demensions are slightly larger
(by 1/2 inch in width and depth) and a Mini-Circuit Labs TUF-1
mixer was used in place of the SBL-1. Bill re-worked the
intermediate stages to redistribute gain to avoid feedback
problems encountered by some builders of the BP-I. An LM380N-8
audio IC replaced the original LM386 in the BP-I to provide much
more AF gain.  Tejas offers the BP-II in kit for only for 40, 30,
20, 17 and 15 meters. The new manual is MUCH better than the
manual that came with my BP-I. This is not a beginner's kit, so
beware! The kit conforms to the guidlines setforth by the QRP
ARCI on homebrew gear. The less experienced builder should have
no major problems IF HE/SHE PAYS ATTENTION TO DETAILS AND TAKES
TIME TO READ AND RE-READ THE INSTRUCTIONS CAREFULLY.  The bigger
cabinet offers more room for options and accessories like keyers,
SWR/P circuitry, etc. The cabinet is the same nice looking
anodized aluminum with crisp black silkscreened lettering. Front
panel layout is well thought out and not cluttered.  The design
of the rig is sound and duplicatable results are obtained between
radio indicating that Bill did his homework on the R&D end.  The
rig worked well and, when compared to my Argosy-II could hear
everything that the Ten-Tec rig could hear. The BP-II is a direct
conversion RX and, once proper Zero Beating techniques are learned,
proves to be a breeze to tune. The BP-II suffered no AM breakthrough
(and with WBAX only 1/4 mile away from me, AM breakthrough is a
problem at K7YHA). The design is "bullet proof" and plays well. The
dual stage CW filter provides 180 Hz and 110 Hz bandpass,
respectively. Wide open the receiver passband is about 2.7 kHz wide.
I could detect no difference in RX performance between the BP-I and
BP-II.  The TX put out 1.9 watts into my calibrated dummy load and
provided some good DX on 30 meters using the Carolina Windom. TX
waveform was clean with no tendency to click or chirp. QSK was as
good as the Argosy. No thumps or pops were heard at 20+  These
single band rigs are a great idea for the traveling QRPer. My review
rig drew only 23 mA on RX and about 300 mA on TX. A single 4.5 Amp
Hr gell cell can run this rig for an entire weekend of DXing with no
problems. This little radio comes as a complete kit  with everything
except the battery, antenna and key provided. It's nice styling an
size make it a very good choice for the active QRPer.
Price is $159.95 plus shipping from Tejas RF Technology,

Well,

the review sounded great.. after building and testing many a
QRP.. you better bet your bottom dollar I WOULD NOT spen
$160 for a DC receiver. There are a bunch of good Superhets
available for that price.

Wonder if Chuck ever got his version I going. As far as a
remember it was the only kit I can recall him saying didn't
work.

BEWARE DC receiver. I had a great time with mine.. it is a
big challenge compared to a Superhet to use.

Subject: 1 bit DDS?

I've been thinking about Direct Digital Synthesis and have a question.
A typical DDS (such as the one in the recent 73) consists of some
digital logic implementing an adder, a lookup table to generate a sine
function, and a digital to analog convertor (DAC) to produce a sine wave.
The DAC is usually the hard part.

My question: For receiver purposes, in which you're going to drive a
"switching" mixer such as a double-balanced mixer from Mini-Circuits,
why bother with generating a sine wave?  Why not just use the
most-significant bit of the adder output to drive the mixer?  After
you drive a DBM with big sine wave, the wave is essentially a square
wave anyway.

Well, not exactly.  The problem is phase jitter.  If you do the above,
your *average* frequency will be what you set it to, but the
instantaneous frequency will be all over the spectrum.  For an
example...

Say I wanted an output frequency from my DAC that was 1/3rd of my DDS
oscillator frequency.  The first two cycles would come out (looking at
the MSBit) as 1,1,0,1,0,0.  The first cycle would have a high signal
for 2/3rds of the time, and the second would have a low signal for
2/3rds of the time.

The way to make a square wave without all the phase noise is first
make the best sine wave you can, *then* square it up.  Otherwise, all
you'll hear is a buzz... :-(

an into a gnarly bad problem with the transmit mixer...  Using the
provided 22pf caps in parallel with T5 and T6 resulted in a truly
*horrible* pattern on the spectrum analyzer.  Instead of a nice, clean
'spike' I got kind of a ramp going up to my signal from below (and
occasionally from above).  On a freq counter it showed up as unstable
numbers.  When I could get it stable (over a small range) it hadtwo
sideband signals, often above the -30dbc limit for being legal.

I found that two 18pf caps worked better, but having an analyzer was
really needed if you wanted to be FCC legal.  On mine before changing
the caps, the worst problem area was right around 14.050 to 14.080 -
not really good for QRP use that way!

I know others have built this rig - Danny's old quite a few.  Anybody
else having 'interesting' times getting it working?  FWIW, once it
*is* working it seems to be really nice.  Sounds clean, and the audio
is very nice on the receiver too.  Full QSK makes it even better.

I would recommend you pick up a copy of Solid State Design, too.
Although SSD is getting old, it has several articles on test
equipment construction.

If you have a general-coverage HF transceiver, you have most of
the test equipment you need. You can listen for oscillators and
peak them on the receiver, and use the transmitter as a signal
source for receiver work. As a bare minimum, you need a sensitive
voltmeter with an RF probe. It needn't read accurately on RF,
just be capable of showing when a circuit is peaked. A scope is
even handier for such applications, but you can live without one.

If you have some QRP-frequency crystals, you can make up signal
sources for receiver testing and alignment. The hardest part of
building for me is getting the VFO on frequency. You can do
this with a general-coverage receiver, but a counter is faster.

We strive to publish projects that can be reproduced without
exotic test equipment, because most of us don't own spectrum
analyzers, either! Broadband circuits have been a real help
in this regard, as they require no "tweaking."

Good luck and 73,

As some of you might know, I am the editor of QRPp, the Journal of the
Northern California QRP Club.  Mike Siegel, KI6PR, one of our members submitted
this review for publication.  I have not seen anything on it yet, and imagine
several of you are interested.  Here it is, a pre-publication preview.  Contact
Mike if you are interested in reprinting.


              Product Review: Ten-Tec Model 555 Scout HF Transceiver

     In the Amateur Radio sales market, there has been an increasing trend
towards more features in basic rigs. These additional "whips and bells" have
also brought much higher prices for most manufacturers' bottom-of-the-line
"basic" radios. As we have all discovered in the QRP game, "more ain't
better". Ten-Tec proves this with the introduction of their Model 555, which
they have named the Scout.
     The night before Dayton was to open, I had a telephone conversation with
a ham about aspects of mobile operation; this ham reported rumors about a
new mobile rig from Ten-Tec, that was to be unveiled the next day at Dayton.
I was so fascinated by the reports and rumors, that the very next morning, I
called Ten-Tec to place my order. The rig arrived August 2, packed in the
usual generic boxes that Ten-Tec uses for shipping - no resale value on THEIR
cardboard!
     The Scout is a very unique rig, not only in it's simplicity, but in the
design itself, and even moreso, in the way it targets it's sales market. The
simplicity of design sticks to Ten-Tec's "less is more" approach to keeping
controls and features simple, but effective. No fancy bells and whistles here
-- just some basic controls that do exactly what they're labelled for.
     The design itself is unique, as well. Rather than cluttering up the
front panel with band switches, or crowding the interior with other boards,
the Scout uses interchangeable plug-in modules, one for each band, 160 though
10 meters (the lower half of 10, 28.0-29.0 MHz). More on this later.
     Even the market that Ten-Tec is targetting is unique. The rig offers
features and specifications that appeal to the experienced mobile operator,
such as large-digit display and built-in keyer. But it also offers something
for the Novice operator on a budget as well - a low entry-level price. For
$495, the Scout comes with one band module (your choice of band), and allows
for the addition of other bands at $25 each, as the operator can afford to
add them. This rig even allows for those of us that only operate on one or
two bands, in that you only purchase the bands you're interested in. To top
it off, the Scout is actually SMALLER than Kenwood's TS-50 (see specifica-
tions below). Quite a unique package, in all.
                           FRONT PANEL CONTROLS
     The front panel of the Scout is simple in layout: two concentric knob
controls, three miniature bat switches, and a large vfo knob. The digits
are a HUGE .56" tall, and accurate to 100 Hz; the MHz digit is actually
painted on the front of the band module, and at first glance, appears to be
integral to the rig. The bat switches are multi-function. The first switch
is simply for power on/off. The second switch activates the RIT, or sets the
speed of the built-in keyer. The third switch either activates the optional
noise blanker, or activates the TUNE mode.
     The concentric knobs offer precise controls for volume, mic gain, RIT,
and filter bandwidth. A word about the filter: Ten-Tec has included in the
Scout their patented Jones filter, a variable-bandwidth 9-pole crystal filter
that offers filtering from 2.5 to 0.5 kHz. More on these functions later. The
Scout also sports a small meter, indicating signal strength, relative power
output, and an SWR function (controlled from the rear panel).
                               REAR PANEL
     The rear panel offers just as simple a layout: aside from the expected
ground lug and SO-239 connectors, there are connectors for DC input, an
auxillary 13.8V DC output, TWO 1/8" key plugs -- one for a straight key, one
for a set of iambic paddles, and a mini-bat switch for calibrating the SWR
function on the front-panel meter. More than half of the rear panel is made
up of heat sink, with the remaining connectors and controls all located
towards one end of the rear panel.
                                OPERATION
     For as simple a rig as the Scout appears, it also operates the same way
-- simple. The band modules slide in smoothly, yet have a snug fit. To
remove a band module, each module has a small lever on the front to "pop"
it loose from it's socket. Each module covers a 500-kHz segment, plus 50 kHz
overshoot at each end of the band. To cover the entire 1-MHz portion of 10
meters, the 10-meter module has a small sliding switch that toggles between
the 28.0-28.5 and the 28.5-29.0 segments.
     Once powered up, the rig demonstrates some audio hiss; in certain other
rigs, I have associated this hiss with excessive RF gain. In this case,
however, the hiss is audible only when the Jones filter is wide open. The
audio that one hears is definitely affected by the Jones filter - when the
filter is wide open, one tends to hear more highs in the audio, and as the
filter is tightened, the audio becomes a very pleasant, mellow, almost
broadcast-quality. In the CW mode, the filter can be cranked all the way
down to 500 Hz, with no detectable ringing or attenuation of target signals.
Needless to say, I am VERY impressed with this new filtering system.
     The mic gain is still something of a minor mystery to me; I can't seem
to deliberately over-drive the audio. Like most other Ten-Tecs, the Scout
uses an LED indicator for proper ALC adjustment - the LED lights up on audio
peaks. I deliberately adjusted the mic gain so that the LED was constantly
lit, and was told by other stations that the audio was not at all objection-
able. With the mic gain properly adjusted, however, and using the optional
700C hand mic, I received glowing reports of truly high-fidelity audio; one
station even remarked that the audio reminded him of the best audio from the
days of AM! The 700C hand mic, by the way, while appearing clunky and cheap,
is actually very light and solid, and demonstrates no pop or creak in the
audio.
     Rather than a conventional VFO, the Scout uses a PTO (permeable-tuned-
oscillator), using a large variable inductor. While I would not call the
tuning knob stiff, it does require a small effort to turn it. I would con-
sider this something of an advantage to a mobile rig, since it forces you
to make deliberate tuning adjustments. The tuning is relatively slow and
positive, both also mobile advantages. The knob turns smoothly, with no
discernable backlash.
     The RIT gives a solid 3-kHz spread, 1.5 kHz on either side of the VFO
frequency, and the variances are reflected in the large LED display. The
display is also used to indicate the iambic keyer speed, when the mini-bat
switch is activated. The keyer operates from 5-50 wpm, but will automatically
default to 25 wpm, each time the rig is turned on. Keyer speed is actually
controlled from the iambic paddles; while in the speed-display mode, if the
dit paddle is struck, the speed increases, and in turn, decreases each time
the dah paddle is hit.
     The optional noise blanker is of a standard type, focused primarily
on ignition and pulse-type noise. Unlike many other factory noise blankers,
however, the Scout's NB does not appear to be prone to incurring buckshotting
of received signals, as is common in some other rigs.
     On the air, there is no mode-switching; simply hit the paddles if you
want CW, or key the mic if you want SSB. The sideband selection is also
automatic, dependant on the band you're operating; unfortunately, this does
not allow for running the opposite sideband, but one can't have everything.
     In the CW mode, Ten-Tec's famous full (REAL) QSK is flawless and fast.
No chirps or other anomolies can be heard while operating (sorry, I only
took it to 42 wpm), and the keying and shaping are quite comparable to the
Omni-V - smooth on both make and break, and steady in between.
     All in all, the rig has received nothing but compliments on the air,
even though I went out of my way to deliberately elicit any negative comments
from my transmitted signals. The most interesting part is that nobody even
realized that I was running only 50 watts! As the rig comes out of the box,
it is factory pre-set at 50 watts, but is externally accessble for adjustment
down to the 5-watt area. There is a trick to this, however; when Ten-Tec was
field-testing the Scout, they found that the tune mode could cause fuses to
blow. So before shipping, they re-configured the rig so that the output in
the tune mode was limited. In making this change, however, they restricted
the amount of adjustment possible for operating power output. Ten-Tec has
promised to put out a mods sheet for moving a jumper to defeat this restric-
tion.
                          MISCELLANEOUS COMMENTS
     The fit and finish of the rig is on a par with virtually all the other
manufacturers, providing clean lines and a tight fit. Ten-Tec is still using
the heavy glass-epoxy boards in their construction; most of the rig is built
on a single, large board, with several smaller sub-assemblies (NB, etc.)
mounted in areas set aside especially for such mounting. The interior of the
rig still has lots of room in it, presumably to allow for owner servicing or
modification, both of which Ten-Tec still highly encourages.
     The manual is very complete, including operating instructions, service
instructions, and even schematic diagrams of the plug-in band modules. There
is even a list of connectors, giving the Radio Shack stock numbers! Ten-Tec
has always had an outstanding reputation for customer service and support,
and this is also borne out by inclusion of fax and modem phone numbers in the
owners' manual.
     Ten-Tec also offers a line of optional accessories, including a mobile
mounting bracket, a 200-watt antenna tuner, and a weighted iambic paddle.
                                 SUMMARY
     While this report is somewhat UN-technical, I personally don't feel
that bench tests mean a whole lot. I prefer instead to see just what the rig
does and sounds like on the air. And quite frankly I'm impressed with the
Scout. I expected a bare-bones rig, and instead, got a radio that I'm going
to have a lot of fun with for a long, long time.
     Would I change anything on this rig? Maybe. I think I would actually
prefer a separate RF gain control, independant of the other controls and
functions; I find this feature useful in even the most sophisticated radios.
And I would prefer to see the Scout use 1/4" CW jacks, just to facilitate
some standardization and swapping around of keys and paddles. But for the
price, I can't honestly think of another single thing I would change.
     While this review has been centered solely on the 50-watt version of
the Scout, Ten-Tec says that they will be producing QRP version, rated from
5 watts down. I look forward to hearing this rig on the air. I really think
Ten-Tec is going to get a LOT of attention in the next year. And for all
the right reasons.

To: [e-mail]

I would just like to echo exactly the review comments of the Ten Tec
Scout provided in the message from Doug Hendricks.  I have now used
mine intensively for almost three weeks and it is an outstanding
radio.  I cannot criticize anything but the minor items noted in the
review.  The receiver is excellent and it is a joy on CW.  It held it's
own in the contest last weekend as I hunted and pounced for kicks.  I used
it portable and used a 7 amp/hr gell cell with no problems of clicks or
chirps.  I also have received glowing audio reports on ssb.  I consider
the radio an absolute bargain for the money.  Am I pleased with it -- that
should be obvious -- Would I buy another? -- You bet.

Gang:
   Here's the next project: a 160M phone xmtr; sorry it's AM but these are OLD
project books! Just the simplicity of it should make it fun to build and play
with. It's VFO tuned by adjusting the slug of L1. In fact you can use this on
75 meters (and there IS some AM activity on 75) just by changing the final
L/C network accordingly. Note that as various antennas are tried, the frequency
will change markedly, necessitating readjustment of the L1 slug. The microphone
should be a low-impedance crystal type.

Since the xmit frequency can change as you change antennas, I bet a strong
wind blowing against a longwire antenna will cause a little `swing' in
frequency...

From: Clark Savage Turner WA3JPG <[e-mail]>
Message-Id:  <[e-mail]>

Anyone out there familiar (or want to become familiar) with the older
OMNI ?  I have an OMNI-D series C, the precursor to the Corsair.  I
am having some funny (read: hard to diagnose) problem that is driving
me completely nuts.

Briefly, I have 50 db less receive on ONE band only.  160 meters is
way down, all the other bands seem OK, they may be down a little,
but not much.  The "resonate" control (preselector) will peak in the
160 meter band, but it peaks much higher towards the bottom of the
160 range, and loses sensitivity rapidly above 1.8.  The receive antenna
seems to come through the pin diode attenuator (which seems to work
normally....) and then to the RX trimmer board with some fixed caps
and a trimmer cap.  I have replaced the 160 meter caps.  It is not
them.  Then the signal goes to the RF amp which seems to be a parallel
tuned inductance for adjustment

I know the problem has to be in there, for when I connect the antenna to
the mixer directly, I have plenty of signal on 160 (perhaps the solution
is to wire the antenna directly there for 160, hi hi).

So, how does a pin diode work for an attenuator?  Is leakage on one
frequency possible?  AND, could the parallel tuned inductors have come
out of sync in such a way as to affect only 160 at one end of the band?

.........help!!!!  I really like the radio a lot, and I want to use it
on 160 as well as all the other bands.

Well folks, here it is, I guess I finally got The leagues endorsement to
establish an ftp site for mirror imaged artwork for the purpose of creating
circuit boards.  Two questions arrise:

1. Previously Bruce had offered his system as a site.  Is this still available?

2. Any preferences on the file format?  I originally thought postscript, but
   it may be a lot easier for .pcx format for many people?


    Because most of my projects are qrp related, I think that some of you
may get a kick out of being able to ftp an artwork, then print it out with
a laser printer and iron on a pc board.  (reference July 1993 QST for this
process.) I have had a lot of luck scanning artworks from QST, 73 and the
handbook.          73 all Brad Mitchell WB8YGG

It's fine for you to scan the artwork for personal use. In some cases,
the authors permit personal use but prohibit commercial use of the
artwork. Any restrictions are noted on the template package and artwork
we provide.

>WB8YGG  ([e-mail])

We started distributing normal and reverse-image versions of PC board
templates last week. Lots of demand since the article came out. We have also
made available postscript files for artwork for some microwave projects
that were developed here, with good response.

In many cases, though, authors design PC boards manually or with software
that does not support postscript, so all we have is a paper or film copy.
I'd be interested in seeing the quality of artwork you have scanned in.
(We have all manner of postscript output devices here...)

I have no problem if you want to establish an ftp site. It's something
we might consider doing at ARRL in the future, but right now I don't
have the resources to put into starting one up. If you want to
do it, though, that would be great! I'd be glad to provide whatever
electronic files I can, and paper copies of everything else that's
in the public domain.

Let me know what you think.

Hello All,

    Well let me cast my vote for the Postscript format. Although we run
the gammut of devices here, they all seem to be compatible with this format.
I have yet to mask and etch a board in this manner, but I believe what
we're looking at is a postive version of the artwork, not the negative.

    On-line artwork, a fantasic concept!

Well I have some good news and some bad news.

I ftp-ed a neophyte file to think.com
in the directory /pub/radio/ham/qrp/artwork.

The problem is that I can't seem to get the thing into Postscript format!!!

I  sent it there in .TIF (TARGET IMAGE FROMAT)

The Image is mirrored not negative.  It consists of 8 mirror image artworks

of the Neophyte Receiver.

Mirrored is the requirement for ironing on.

I'll try to get Post script format, but no guarantees at this point how

successful I will be.  Let me know if anybody trys the .tif format.

P.S. Can anybody convert it to Post script?  Also, Designer software on the

P.C. handles .tif files nicely. 73/72 all Brad WB8YGG

Well, folks stay tuned we may have this all figured out yet.

The current file neophyte.ps in the directory /pub/radio/ham/qrp/artwork

,on think.com, I was not able to print.

I will say that if and when this process gets ironed out for creating

the .ps file that the neophyte artwork is the worst that I have tryed to scan

so far.  It wasn't too good a print in the article, but I have made 5 neophyte

boards for myself.  No not to sell, Gary N2JGU and I gave a demo on the iron

on process at our local Brockport Amateur Radio Klub (Bark) meeting, and it

generated several of these things. Even though the original image wasn't the

best the boards turned out pretty good.

his picture and his son Danny and some of his goodies, like the HW9 and
the OHR Spirit.   good job.

also a picture of the famous Jim Kearman, KR1S.  scared me when i
first saw it.  thought that was a Hallicrafters TO keyer instead of
the VFO.  :-)  Jim, too neat a setup.  real hams can't get to the
desk to operate much less see the rig......  of course we all know
that's not how it looks before and after the photo was made.

Randy, look at page 109 (AA2U).  maybe he can tell us all the ten
flags.  the IC-707 looks like a real neat rig.  noticed that there
wasn't a price tag.  is this going to compete with the TenTec scout?
9.4 x 3.5 x 9.4" isn't too bad a size for GC rcvr and all the ham
bands and power adjustment on the front panel.  anyone seen this

  I read but seldom contribute to the QRP list, but ...

  I got my Sept QST yesterday, and my 10-yr son Ben (KB1AIH) has already
  sent in his postcard hoping for that ICOM 707.   Flags are his "thing",
  he's written a Visual Basic (Windows) program released as shareware that
  displays flags of 120+ countries.  He rattled off all ten right away.

  He's trying to dream up enhancements for this program of his, to send an
  enhanced version to people who register their copies.   Right now he's
  working on a scrolling info box - population, etc.

   It just occurred to me that maybe some of you DX fans might have some
  ideas of some good sources for info on "rare" countries.  Right now he's
  working from the "World Almanac" and a CD-rom encyclopedia.   He wants to
  distribute his product to schools, so he needs general interest info,
  (not just the callsigns of "rare" hams!).   Any ideas?  Online sources?
  Consulates with BBS?

Hi everyone:

OK,

I have built a few kits recently (quite a few). Well I
thought I would get to take a break and work on things like
mobile antennas. Things just don't seem to work out as
planned.

While looking throught the advertisement section of QST (one
of my favorite sections..HI HI), I had noticed there was a
kit that even Chuck hasn't talked about yet. This is the S&S
Engineering ARK40 (think they now make a 20 also).

Ad:
Superhet
Synthesized to 100Hz
RIT +/- 500Hz
Sensitivie 0.3uv
CW crystal filter
CW audio filter
AGC
3-4 watts
Full QSK
Sinewave sidetone
Exruded chasis
coils pre-wound
silkscreened boards
complete kit
guaranteed to work

The $269.95 price tag really put me off. I paid a lot less
for my HW9 with the WARC band pack and all the replacement
parts I blew up along the way since I built it.

I got the box in the mail yesterday. The manual is the size
of the computer text book I am going to use this semester.
The quality of the manual is better than the text I am about
to use. The photos are the BEST I have seen including the
ones in QST.. I would love to have the photographer do the
photos for my articles. The manual is extremely well written
and clear. Step by step with explanations of how things work
and a good trouble shooting section.

Each one of the boards and its components are packaged
seperately. The boards are beautiful. The parts all look top
quality. The case is a lot smaller than it looks in the
magazine and should be good for my portable operations. The
rig looks like it is going to be very rugged. There are over
1000 solder connections.. should keep me out of trouble for
a little while (probably not).

Will keep ya'll posted.

I have an AZDEN PCS-2000 which seems to be reducing its output
power when I try to transmit into a matched antenna. If i unmatch
the antenna the led's indicate that me power output goes up.
The thing is i would rather not xmint into a missmatched
antenna and it reduces the receive sensativity. Any ideas
on what to check first. I do not have a good understanding
of how crowbar circuits work. Thank's

Jeff,

Doesn't the ARK40 use thumbwheel switches?
I think it would be tough tuning the band with thumbwheel switches.

Sorry, qrp and boatanchor readers, this message is only peripherally
related to either topic.  But you folks have a lot of good things to
say, and I could use some advice/war stories.

I am traveling to Orlando (2nd time in 2 weeks) next week (30 Aug) and
will be trading in a piece of gear at AES.  I am in the market for an all
purpose antenna tuner.  Seems like MFJ is the big mfr out there, and
besides, AES sells them.

I will be getting approx. $ 125 trade-in credit.  I don't want to spend
a heck of a lot more.  I plan to do some playing around with random wires,
center and end-fed, balanced lines, etc.  I want to run 100-200 watts
CW/SSB, boatanchor CW/AM, and also QRP when I get/build a rig for this.

I have always loved roller inductors (still have a breadboard tuner that
I built years ago that uses one) but these models are $$$$.

Any ideas?  Are the MFJ non-roller inductor units (like the 300 watt model)
adjustable enuf for good matching to "anything"?  How is the SWR/wattmeter,
dummy load, balun?   I do remember hearing that these units often need to
be gone over to eliminate cold joints and loose connections.  Any war
stories?

Will be QRT by 1600 this Friday.

the ARK40 is the rig that i was talking about that i saw at
hamcom in dallas in june.  Dick ????? owner and designer was
here showing it off.  it sounded great and worked great in
the QRP ARCI hospitality suite in arlington.

Jim is right, the thumbwheel switches aren't for everybody.
i don't care for them myself.  may be ok on HT's, but not
on HF gear INHO.

the quality is very good and like Jeff said, the docs are
great.  CAD drawings and all.

let us know how you like it Jeff.

klaudon(?) asks about the MFJ tuners....

KR1S, should I tell him?

I have the MFJ-948 (no dummy load - or is that no, dummy - load!) and it's
actually pretty good, ONCE YOU REPLACE THAT MINIATURE INTERNAL BALUN WITH
SOMETHING HEFTY. I suppose it is designed to handle maybe 600 ohms max, and
my center-fed "zepp" probably presents it with at least several thousand
ohms. So, I replaced the balun with my own. I glued two FT-140-61 Amidon
cores and wound 16? bifilar turns of #18 thermaleze wire on it. Works FAR
better, now, and even far better than when I had tried a Radio Works Remote
Balun ($28.50 lost to an experiment).

Per KR1S' instructions, I wound as many bifilar turns on these big cores as
was wound on the original balun in the tuner. I think it's 16.

There are always war stories!  I have been using an MFJ 949B Deluxe
Versa Tuner II for about year or so.  Bought it used, at a hamfest,
for $30.00.  Used it with a 135' dipole, fed with 450 ohm twinlead, on
75, 40, 20, and 15..  Rig was my TR-4C.. Results were good.  Also used
with a Rat Shack HTX100 and a 10m vertical dipole.  Again, results
were good.  Power readings are within specs stated in manual.  SWR
bridge works.  I am not overly impressed with the dummy load or the
balun.  It was worth the 30 bucks but, I like my MN-2000 better!

Opinion:  If I already had a roller inductor, I would spend my money
on a good SWR bridge, a cantenna type dummy load, maybe a good balun,
a coax switch and a dozen PL259's.  That ought to almost eat up $125
and would provide the same capability and much more flexibility.  With
a couple of variable caps, you can wire up your inductor as a
T-network tuner and duplicate the MFJ...

Other options (if that money is burning a hole in your pocket) would
be a Drake Mn-4, or MN-2000.. These are pi-network tuners with a
wattmeter and SWR bridge..

I'm sure our compadres can come up with some additional comments.

Which way will you be traveling?  There is a hamfest in Madison, Ga,
on Saturday.

QRP gang,

Sorry to those of you who have been trying to get added or removed from
this list for the past several weeks.  Because of some procedural changes
for maintaining mailing lists at this site, many of my changes to the

reappeared on the list after you were taken off, and some of you
disappeared for a while after being added, and some people's who had
address changes had their addresses just change back and forth!

Anyway, sorry for the problems; they were my fault.  I now have the list
reconstructed as best I can from the information I have.  If you receive
this and had asked to be removed: sorry, please remind me, and I will take
you off once and for all!  If you want to be on the list and aren't
receiving this :-)...well, I hope you think to ask again.

Cheers, and sorry for the confusion,
