Brian:

 >> "Can't we all just learn to get along"

I agree.  It's amazing to me that, with so much we have in common within
amateur radio, we can't seem to just coexist with one another on the air or on
the nets.  Seems a shame....

Subject: Update To QRP Quarterly Index

Gang, I have updated the cumulative index to the ARCI QRP Quarterly.  The Index
is for the years 1985 to 1993 (present) and includes all large format editions.
I have attempted to index everything, from letters to the editor, to individual
items in The Idea Exchange.  It is long, so be ready.  Hope you enjoy.  72,
Doug, KI6DS

Preface:  This index was done by KI6DS, Doug, who makes it available to all

QRPers.  Hopefully you will find it useful and handy as I have.  I suggest
that you put it in your word processor and use the search feature to find
keywords.  The categories are rather broad, but necessarily so.  I will do
updates each year and make them available.  If you would like to have
reprints of back issues, I have them available for $10 per year, plus $3
postage per order.  I have the years 1985 - 1993.  If you order all 9 years,
there is a special price of $83.  Each year is bound in 1 book, so please do
not ask for individual issues, i.e. April 88, as I cannot make them available
that way.  Please feel free to distribute this to anyone as long as it is not
used in any way to make money.

My address is:  Doug Hendricks
                KI6DS
                862 Frank Ave.
                Dos Palos, CA 93620
                209-392-3522
Best 72, Doug

I've been trying to be as gentle in my requests, both on here and
via email, but I see it's not working so here I'll be very direct
and to the point: Up until about a week ago this email net was a
very pleasent - all the posts were either technical or operational -
no soapbox views were sounded nor wanted. We subscribed to this
net because we were QRP and mostly CW fanatics. You newcomers MUST
realize that there is no room for code vs no-code debates on here -
save that crap for r.r.a.policy. You've subscribed to a mostly CW
email net. Every remark you make comes into our private mail boxes.
If you want to use this email net as your soapbox you can easily
be cut off the list.

Before you post anything you should ask yourself:
- Does this have anything related to the purpose of the net: QRP
  (Andrew: your C.B. handle has nothing to do with amateur radio QRP;
  (The mini-thread about homebrew beer has nothing to to with QRP)
  (The whining `can't we all just get along' has nothing to do with QRP)

- Do I really want to invade everyone's privacy by sending this to
  their mailbox?

- Will this cause any division within the net, or will anyone be offended
  by what I have to say? (again, this is not a newgroup)

You have chosen to subscribe to our wonderfully informative little net and

Subject: Project 11: 15M QRP xmtr
Message-Id: <[e-mail]>

Here's a two transistor 15 meter xmtr gotten from Bert Simon's book
104 HAM RADIO PROJECTS (1968). Bert says: "As any novice knows, 15
meters is where the action is, at least if you're a DX addict. So,
imagine the fun in telling your 1000-mile contact that you're running
less than 1-watt into a 2-transistor rig. It is important that you
use a miniature 5-prong coil form for L1. Follow the directions in
the parts list to the letter. L2 is wound over the lower turns of
L1, using the same coil form pin connections. As you can see in the
schematic, the 40-meter crystal oscillator output is tripled to
15 meters.
"Tuneup is simple. Depress the key (intermittently to avoid damaging
Q1-Q2), noting the meter reading. It should be 5-8 ma. (If it isn't,
adjust C1 until this range is reached). Switching to the other
meter position (PA), adjust C1 for maximum. Using an output bulb
(neon or #49) adjust C8 for minimum capacitance. Now tune C7 for
a meter dip to about 4.5 ma. While dipping C7, tune C8 for maximum
bulb brilliance."

Notes: Q1 and Q2 have a marking: (s) on the schematic which appears
to be the case of the transistors - on both cases (s) goes to ground.
The numbers next to L1 and L2 are the pin numbers of the coil form.
The wiring for SW1: If 3 or more wires meet without the junction
symbol * then there is a `jump' (no connection). The positive
terminal of B1 goes to ground.
The usual warning applies here as with the other 9 transmitters:
these circuits are old - tighter emission standards are in effect
now that weren't when these were first published; make sure you
signal is `clean' by applying proper filtering if necessary.

Subject: Direct Synthesis

Background:

I am intrigued by the use of ``traditional'' (7400-series) digital logic used
to generate square waves on the standard bands (e.g. CW segments beginning
at 2^N * 3.5MHz). But I dislike building multiple Pi networks with multiple
coils to wind and (most of all) flipping many switches to change bands.

Question:

Has anyone tried direct digital synthesis on the lower HF bands? That is,
binary adder/accumulator is driven by a clock and increments a waveform by
a programmable, constant phase? By ``direct'' I am excluding binary rate
multipliers a/o programmable divide by N counters -- I'd like to be a purist
where phase noise is concerned. I'm also looking for reasonably small parts
count -- I can live with an eight-bit adder and just a few rock-solid
frequencies in each segment.

While on the subject of 7400 meets QRP: every time I come across "50 ohm line
driver" in my old TTL data books I have this sudden urge to breadboard one up,
solder a strand of RG-174 to an output pin, and run the strand out the window.

So question two: has anyone tried using digital gates as PAs at QRP levels?
Sure, it takes one back coils for pi nets and to increase impedience, but there
are some high current drivers out there with built-in latches, asyncronous
resets and other stuff that would reduce parts count of a small QRP CW rig. Is
this practical, or does Miller effect burden the design of the exciter stage?

Yrs,

Yah..I know its late... but the parts were laying there staring me in
the face, so I had to do it.

This one is built on peg board ( very big perf-board )...just because!

No special layout , but the transistor I used...some unknown somthing...

Let me follow Jeff's well-taken comments on net etiquette
with an ethics comment of my own:

Please check the To: field of your messages and reply only
pertinent list replies to the list.  Please do not forward
(or Cc:) personal replies to the QRP list.

Very often I will reply directly to a person if the
comments I have might be construed as personal in nature or
I deem the follow-up questions I am asking as not focused
at the group as a whole.  That is a personal decision I
make to reduce mail traffic.  I prefer not to see my
personal remarks in a private (non-QRP list) message
later reappear on the net in a reply or Cc: to the list.
This has happened on several occasions, at it upsets me.

I don't know about your mail reading programs, but I can
see whether a message was directed at the list (To:
[e-mail]) or to me personally.  I take that as one
distinction between levels of private and public messages
that we are still able to have on the largely public-
natured Internet.  I will not forward any message directed
at me personally to anyone else without first obtaining the
original authors permission, regardless of whether the
content may pertain to a discussion at hand.

If you follow me, can someone now explain to me the tendency
for a large number of us to Cc: everything to the list?  Why
send a reply directed at a person along with a Cc: of it?
They'll get the list-aliased message regardles, and they
don't need two copies.

Keep up the good work otherwise, I'm learning alot about
radio and QRP from you guys, the experts!

    Yes, there have been a number of HF DDS srticles recently, and
there will be more.  For lowest parts count, there was an article in
?June ?July of 73 magazine, using a Harris NCO and CA3338 DAC that
interfaced via a parallel port to a PC to generate signals to about
12MHz.
    There was also one earlier, in December 92 and January 93 of
73 that used a Qualcomm NCO and the CA3338 DAC to go to 21.5MHz.  This
one is modular - the first article used diodes for the frequency
setting, and in Jan 94 there is supposed to be 2 more articles, one
using a parallel port and one using thumbwheel switches.  I'm much
more familiar with this series - I wrote all but the parallel-port one
and I built the first proto of that, too. :-)
    If you wanted cheaper and can stand higher parts count, an
outfit called Novatech has a DDS using 7400 chips to go to 512kHz, and
if you substitute faster chips you could get it to go into the really
low HF bands, but it will wind up costing as much as the others once
you buy new chips (*sigh*).  I also built one of these, and used a
MC4024 VCO with MC4044 PLL chip to multiply it by 100.  It took
several 4024s to cover up to about 20 meters, though, and those chips
too are getting hard to find cheaply.

    I've used a lot of 74HC373s as 'finals' in very QRP
transmitters - the problem is at 5 volts p-p you get 62mw into a 50
ohm load.  At 12 vp-p, you get 360mw, and you're pumping a *lot* of
current through the device.  Even with a good heatsink on the chip,
they tend to go up in smoke quickly.
    For HF work, the chips can handle it (re: the Miller effect) -
they're usually used at frequencies of 20MHz or higher, and they have
to make a decently square wave there.  The built-in latches do allow
you to key the output, but it results in a very hard note - very
square edges.  For the sake of the intended listener, use a regular
shaping keying circuit and a single PA transistor (I usually use
something like a 2n3866 or MRF517 for a watt or 2).

Subject: 160m contest as QRP


Hello to all-

  It was a good weekend at my QTH.  I was able to combine three of my
favorite ham radio subinterests at one time -- CW, QRP, and 160m -- during
the ARRL 160m contest.  Operating time was limited to due those proverbial
"prior commitments", but that just meant a higher fun/minute quotient.

  I used the hunt-and-pounce method and made 40 QSOs in 20 sections during
80 minutes of operating at 5 watts.  The antenna here is pretty poor --
an end fed quarter wave wire about 25 feet off the ground.  I use a
T network to tune it to 50 ohms.  Noise levels on the band were quite
low.  There were only about a dozen stations that I could hear but not
work, so I was very pleased.  I heard no stations west of Kansas.

  Did anyone else run this contest?  If so, I'd be interested in seeing
your comments.

  73/2.

Ron (wb8ruq).

Be wary of using digital parts as oscillators, amplifiers, etc. in a radio
(ie; single-frequency) application.  They are designed to have a _wide_
bandwidth and switch _very_ fast, thus generating a lot of spurious
energy.  If you don't like winding coils, you'll love filtering and
shielding like mad to get rid of the unwanted RF by-products.

Digital direct synthesis works very well.  The more bits used to
synthesize the waveform, the less sharp edges involved and the less
unwanted energy in the output.  Unfortunately, the drawback is more
digital stuff switching.

I think using logic parts as RF sources and amps is a neat idea, but be
careful about putting out spurious goop where you might not notice it.  A
repeater owner was just served with a $5000 Notice of Apparent Liability
by the FCC because he was outputting a 243MHz spur on RECEIVE!!  This is
well within the range of most modern parts to leak out a few nW thus
attracting unwanted attention.

Use metal boxes, bypass all the parts extra well, bypass all lines going
in and out of the box, etc.  DON'T use the plug-in breadboards for more
than bench-top lash-up work before building the real thing correctly.

Just being a wet blanket ;-)

Gang,

Worked 20M for first hour of the test on Dec 5th, the QRP ARCI Sprint
started at 2000Z (2000UTC).  :-)  Band was in sad shape.  Worked only
10 contacts, one of which was the famous contest operator, Pete VE5VA,
a member of this group.

Went up to 15M for 15 minutes and worked Pete again.  He had a few
more qsos than I did and he said bands were in sad shape in SK land too.

Let's see now, I've worked him on 40, 20, and 15.  Maybe we can start
a five band award or something.  I'll be at the antenna farm 'til Jan
24th, so any skeds wanted, I'll try to oblige for 40, 30, and 20M.
You can hear a K5FO Special at work.  Laying out the PC board over the
next week or so, as time permits.

I do slow down and I'll move up to the novice band(s).

Subject: December NorCal Club Meeting

The December meeting of the Northern California QRP Club was held at the
California Burger Restaurant at the Santa Rita exit on I-580 west of Livermore
on Sunday, Dec. 5.  32 members showed up with 7 NorCal 40's also there.  Or,
should I say 5 NorCal 40's and 2 NorCal 30's.  The mods are starting to show
up, as James, KI6JD, has his with lights, a keyer, and an audio amp.  Bob
Warmke, W6CYX, has a NorCal 30 and 40, and both have mods that increase the
power output to 5 watts with coverage on the 40 meter model going from 7.000
to 7.150 MHz.  Bob has promised to write up an article for the next issue of
QRPp so the rest of us can play copy cat.
     Stan Cooper is in Japan, but sent his rig that has the front and back
panel silk screened with the lettering and dial markings in black ink.  It
looks really professional, and Stan has very graciously offered to Screen
print the front panels for the rest of the NorCal owners.  All that you need
to do is to mail your front and back panels, that have been painted of course,
to him in a floppy disk mailer.  Enclose postage for him to send it back to
you along with a mailing label that has been pre addressed with your address.
Please do not send money, Stan doesn't want any, he just wants to help out.
But, please do send stamps and the label to make it as easy as possible for
Stan.  He will return from Japan on the 9th of December, and promises to have
a 1 day turn around on the panels.  Stan's address is:
        Stan Cooper
        1390 Market St.,
        Apt. 2024
        San Francisco, CA 94102-5313

    Jim Cates, WA6GER, brought a much asked for item to the meeting.  We have
been able to get 50 more cases that match the case for the NorCal 40, except
that the front and rear panels do not have holes drilled in them.  I am
going to attach mine with an "L" bracket to the bottom of the case, and put
a tuner and keyer in it to match the NorCal 40.  The cases cost us $10 each,
and the club provided the standoffs and special screws at no additional
charge.  If you want one, send $10 plus $2 for shipping to:
        Jim Cates, WA6GER
        3241 Eastwood Rd.
        Sacramento, CA 95821
     Jim Pepper is working on a design to build a digital readout for the
NorCal 40.  He has it designed and the board layed out.  He will be building
a prototype and hopefully will have it for the next meeting.  His article on
the 40M Transceiver that was to appear in the fall issue of Communications
Quarterly was bumped to the Winter issue.  Look for it to be on the news
stand in January or February.  The readout should be cheap to build, costing
less than $25 for the parts and board.
     Wayne Burdick had his "famous" bread board with the newest project, the
receiver section of the Sierra 5, which is a 5 band CW transceiver that will
cover the 40 & 30 meter bands and have options for 20, 17 & 15.  Wayne
describes it as the "big brother" to the NorCal 40.  It has enough audio to
drive a speaker, true agc, and even has an "S meter".  Be patient, as it is
in the R & D stage right now, but Wayne is working on it and it looks like
a great next club project.
     Denis Englander, KD6ETI, brought the "winning" entry to the club logo
contest.  It is oval shaped, with mountains in the backround representing the
Sierras, and the NorCal 40 rig with an antenna and key in the foreground.
The logo says "NorCal QRP Club  Est. 1993".  Dennis is investigating the
cost of getting patches made, and will report back to the club.
     Finally, it was decided to purchase a machine to package the QRPp in so
that it will not have to be stapled, and so that the mailing label will not
come off.  3 or 4 members have notified me that they did not get the QRPp,
just the label, so we needed to do something.  Starting with the next issue,
we will mail QRPp in a plastic jacket, like QST comes in.  The cost is $67
for the machine, and 2 cents apiece for the plastic bag.
        Don't forget to submit your articles for QRPp soon.  We need all
types, and if it applies to QRP, we are interested.  Several of you have
commented on how you like the wide variety of articles.  Keep sending them
to me, and I will keep publishing them.
     The members in attendance received an extra "bonus" for attending, as I
handed out a nice meter to everyone with the assignment that they build a
tuner and bring it to the next meeting.  Bob Warmke brought some 10 turn pots
and gave them away for use as a replacement on the NC40's.  If you get the
chance, come on by to the meetings.  They are loads of fun, and hey, you
never know when one of us will be giving away "extras"!

Measured power out was 700 mw with 14   vdc from a power supply
( I use my scope, and a 51 ohm resistor, then figure from the RF volts
  that I get, the power  E^/R = W      ( ^ = 'squared')    )

While working with it, and finally hooking scope up right, I could se
the the ckt had tons of harmonix....thus why the changes and while at
it, I got more output.

Got 3 stations so far,( and drove a W8 crazy trying to dig me out,while
at the dirty 150mw level.)

 I'll be on this thing this week   , afternoons,   and in evening, and
past my midnite.

 I may try 3709kc...but that Fo is chirpy no matter wot I do.... so I may
just stay on 3699kc.

The recent discussion of DDS reminded me of a silly thing I did once.

I built a WWV receiver using a 74HC04 as an RF amplifier.  Amazingly, it
worked.  But, boy is it hard keeping those suckers from oscillating at well
over 100 MHz.  Also, when you bias those parts for linear operation, they
like to suck power.

How does one process a .tif file?  I'd like to look at these files and don't

A number of PC based tools will read the TIF files, alhough a TIFF file can
have hundreds of options set in it.  They are also very popular in the UNIX
world as well, and can be viewed with quite a few public domain viewers, such
as xtiff or xv.  The Aster*x graphics package reads them as well.  On the
PC side, I can use MS Publisher, and I think that WinWord might handle them
as well (I've got a couple of proprietary viewer too).  Many scanners produce
TIFF output, so anything that can handle scanner files will most likely read
them too.

Well I worked that famous contester, homebrewer and all-round bon-vivant
Chuck K5FO on 20 and 15. Also worked Jim KR1S at WA1MBK and probably lots
of other famous contesters but whose callsigns I don't recognize due to a
very poor memory. As Chuck mentioned, condx were awful, K index was 3,
and the only DX I worked was HP1AC/QRP.
34Qs   155pts * 29SPC * 10 (power 0.9W) = 44950.
QSO rates were staggering! 9 in the first hour, 11 in 2nd hour, then 12,
and 2 in the last hour. I could hear a couple of people on 40 in the last
hour or so but 0.9W couldn't make it.
No homebrew used - hang head in shame - I should at least have hauled out
my 20m Howes Tx kit.

Confusing thing, and something to look out for next time, was that there
was another contest of some sort going on that also gave out a 4 digit
number. I don't know what it was but I had a QSO with VE3AHJ who gave me
a number of 6191 which looks like a good ARCI number. But he didn't give
out his province (i.e. didn't follow the regular ARCI exchange format)
and he sounded very loud given the condx, so I asked for his power. 50W!
Even if the 6191 was his ARCI number, I believe that his 50W would mean
you'd have to use the 50W (a 2 point QSO) instead of his number
(a 5 point QSO). Heard several U.S. stations later on giving out numbers
in the same way and not giving their state.

    Perhaps I can shed a little light on this question.

The .tif files are in "tagged interchange file" format. This is a
raster scan type file. There must be 20-30 variants of this format,
including the type used in landline FAX transmission. I have used the
XV utility by John Bradely ([e-mail]) to view/modify/convert
.tif type files on a SUN workstation. I'm sure there are equivalent type
programs for DOS platforms also.

The .eps files are "encapsulated postscript files". These are essentially
regular postscript files with a few extra lines added to make it possible
to import them into various desktop publishing programs. They print out
just like a regular .ps file. To look at them, I use the pageview tool on the
SUN workstation, or Ghostview on my PC clone.

Hope this info is helpful.


BTW: If anyone needs any raster scan format file (including .tif) converted
to any of the following formats, let me know, I can probably do it for you
in just a couple minutes:

    GIF,PM,PBM,X11,Sun Rasterfile,BMP,Postscript,IRIS,JPEG,TIFF

There was a telephoine company employees contest going on.  40M was

I'm making phone calls to try to track down the AMI chips used in the Super
SCAF audio filter in the back of QRP Classics (among other places), and
wondered if any QRPers had built one and had any words of wisdom to share?

And if anybody has current information on where to buy the chips, I'd really
appreciate it; several local (Vancouver, B.C.) suppliers have the S3528
low-pass filter, but nobody seems to have the S3529 high-pass filter.
Silicon General seem to have cloned the chips, but nobody seems to have the
SG3529 version either.

If I can lay my hands on the chips, the price/performance sounds
impressive...

Lab Notes: Kits Galore!


Summertime,  and  the living is easy. It's the  perfect  time  to
build  a kit! You can do it all at once in a mad frenzy, or  work
on it piecemeal. Either way, you're guaranteed fun, education and
true  pride  of ownership. Mike Gruber, WA1SVF,  ARRL  Laboratory
Engineer, briefly discusses kit-building and provides a  valuable
list of kit suppliers.--WB8IMY


Q:   I'd  sure like to try an electronics project,  but  I'm  not
quite  sure  where  to begin. I'm considering kits,  but  is  kit
building really worth the trouble?

A:   Well, when I was a youngster I would watch with  fascination
as my Dad assembled his latest Heathkit project in our  basement.
Smoke  would often curl up from his soldering iron late into  the
night. Friends and family would gather for the grand unveiling of
his  latest  triumph.  A drawer full of  those  red  plastic  nut
starters  that came with each and every kit (remember those?)  is
still  in our basement somewhere! I received quite  an  education
when  I  was finally old enough to follow in  Dad's  kit-building
footsteps.  This  early exposure to electronics  inspired  me  to
obtain  an  Amateur  Radio license and even pursue  a  career  in
electronics.


Q: Are kits difficult to build?  What ever happened to all  those
classic  kit manufacturers, anyway? What about Heath? I've  heard
that  they're  out of the kit business. Does this mean  that  kit
building is a thing of the past?

A:  Whoa! Easy, big fella. Let me answer your questions one at a
time.
      First,  the level of difficulty varies with the  individual
kit.  A very simple kit can require only minimal time, skill  and
experience  to  put  together. Complex kits can,  of  course,  be
considerably  more difficult. It is important to determine  which
kits  match  your  abilities. When selecting a kit,  be  sure  to
consider  any additional purchases that may be required, such  as
knobs and cabinets. You may also need  test equipment to complete
the project.
      Second,  it's true that many of the old kit  manufacturers,
such  as Eico and Knight-Kit, are no longer in the kit  business.
Back in the days of point-to-point wiring and vacuum tubes, a kit
manufacturer stood a decent chance of succeeding in the  consumer
electronics market. They offered better products at lower prices-
-including   products   not  normally   available.   Today,   the
miniaturization  of electronics, modern assembly techniques,  and
cheap overseas labor have taken away much of the competitive edge
that  kit makers enjoyed. Heath, however, is still  making  kits,
mostly of the educational variety. These may be excellent starter
kits to get your feet wet.
     Finally,  it's not true that kit building is a thing of  the
past. True pride of ownership and the thrill of doing it yourself
are  things that mass-produced products don't always offer.  Many
companies  still  make kits to fill this niche.  Just  about  any
skill level can be accommodated if you know where to look.


Q:   Okay, you've sold me. I want to run home right now, warm  up
my  soldering iron!  I'll bet you've even compiled a list of  kit
manufacturers for me.  How about it?

A:  Yep, here's the list. Happy kit-building!

You can run these without the +/- 5V. A 12V supply can be used if you use an
artifical ground (very common technique with op amps).

Many thanks to Ed, WA2SCA, who maintained the QRP mailing list while I
was on vacation for the last 2.5 weeks.  I was in KH6, but as it was a
vacation in celebration of our 5th wedding anniversary, I didn't bring
any ham equipment.

Ed kept several messages for me concerning comments about the list
contents, netiquette, etc., some of which were sent to the QRP-Request
address and some to the whole list.

When I catch up with some of my work and the QRP archives, I will try
to address some of the comments/complaints.

Alas, I did not get back in time to defend my title as the reigning
Eastern Massachusetts Low-Power 160m champion in the ARRL contest this
last weekend (my one and only contest certificate, and yes, there was
more than one entry, but not many :-) ).  It doesn't matter, I would
have operated QRP this year anyway!

SUCCESS!!!!

For the benefit of other interested QRPers, A&A Engineering (714-952-2114)
have these goodies in stock. The S3528 and S3529 are both $6.50 each. They
used to sell complete Super-SCAF kits, and may start doing so again if
prodded hard enough. Their credit card minimum is $20, but since I can think
of *lots* of things I can do with high-Q low pass audio filters (a Weaver
SSB exciter, among other things), I ordered three S3528s and one S3529.

Now to put the rest of the thing together...thanks to all who replied and
offered suggestions.

        Yes, there have been a number of HF DDS srticles recently, and
there will be more.  For lowest parts count, there was an article in
?June ?July of 73 magazine, using a Harris NCO and CA3338 DAC that
interfaced via a parallel port to a PC to generate signals to about
12MHz.
        There was also one earlier, in December 92 and January 93 of
73 that used a Qualcomm NCO and the CA3338 DAC to go to 21.5MHz.  This
one is modular - the first article used diodes for the frequency
setting, and in Jan 94 there is supposed to be 2 more articles, one
using a parallel port and one using thumbwheel switches.  I'm much
more familiar with this series - I wrote all but the parallel-port one
and I built the first proto of that, too. :-)
        If you wanted cheaper and can stand higher parts count, an
outfit called Novatech has a DDS using 7400 chips to go to 512kHz, and
if you substitute faster chips you could get it to go into the really
low HF bands, but it will wind up costing as much as the others once
you buy new chips (*sigh*).  I also built one of these, and used a
MC4024 VCO with MC4044 PLL chip to multiply it by 100.  It took
several 4024s to cover up to about 20 meters, though, and those chips
too are getting hard to find cheaply.

        I've used a lot of 74HC373s as 'finals' in very QRP
transmitters - the problem is at 5 volts p-p you get 62mw into a 50
ohm load.  At 12 vp-p, you get 360mw, and you're pumping a *lot* of
current through the device.  Even with a good heatsink on the chip,
they tend to go up in smoke quickly.
        For HF work, the chips can handle it (re: the Miller effect) -
they're usually used at frequencies of 20MHz or higher, and they have
to make a decently square wave there.  The built-in latches do allow
you to key the output, but it results in a very hard note - very
square edges.  For the sake of the intended listener, use a regular
shaping keying circuit and a single PA transistor (I usually use
something like a 2n3866 or MRF517 for a watt or 2).

Ummm, Waaaaaaait a minute here...  How in the world did you use a 7404

BTW, I've got a ton (500+) of 74XX chips that I bought at a fest for

Message-Id:  <[e-mail]>

I was busy working the CQ WW CW contest 2 weekends ago. I operated from
home and was testing out my new improved antenna system that I have been
working on for the past 2-3 months. I now have a pair of KT34XA's(6 ele
tribanders) stacked on a 90 foot crankup tower. The top one is at 90ft
and the lower one is on top of the second section at about 38ft.

The resulting stack was fed separately or both in phase. I just used
coax switches to change the feed as I am still not finished with the
relay box that will allow me to change everything with the push of a
single button using solid state logic. I will also add a selection for
both antennas fed 180 degrees out of phase for gain at a higher radiation
angle.

I used one of the TIC ringrotors to rotate the lower antenna around the
tower. Seems to work ok, although its indicator ceased reading the
true beam heading by the end of the contest. I had rushed setting it up
so never really got sufficient time to calibrate it correctly.

Here is my score breakdown:

Band    QSO's    Zones    Countries
160    3    2    2
 80    32    10    20
 40    161    23    81
 20    268    30    85
 15    212    24    73
 10    58
        18    37
---------------------------
Totals  734    107    298=> 821,745 points

I used a 2 element 40 meter yagi which is about 6 ft above the top KT34XA
and a full wave 80m loop for 80 and 160m. My score is down considerably
over last year but I guess that is due the few openings on 10m.

I operated the 160m contest last weekend using my 80m loop.

255 QSO's x 33 sections for 16830 points

Just operated part time and didn't stay up very late. Multipliers west
of the Mississippi were nearly impossible for me to work with my 5w
and 80m antenna. Still, the contest was an enjoyable one.

Randy, I've seen ur scores in the past and you do great to say the least.
I am a DXer and contester myself, but in the CW test,I decided to go low power
(100w) on 40 meters single band. I haven't tallied my score yet, but compared
to you it isn't good. I had 410 qsos and 112 countries 35 zones. I use a full

No, I mean 100 watts. Not relevant to QRP but relevant to complementing AA2U
on the fact that he made a lot of qsos on a fraction of the power I used.
Actually, I had planned on using a KW but my amp broke.

    My QRP interests are building and operating, but not operating 40m cw
during a contest. I can handle most of the other bands QRP in a contest, but
not that one.

I don't think Bird makes such an element (5W, 3-30 MHz).
I think we'd (ARRL) would have one if they did! The

it go.

I know that this is not strictly QRP, but I think the subject is close enough
to spare the bandwidth.  I am looking into ways to safely charge some NiCd
batteries that I purchased from 624 Kits.  They are in 4.8 volt, 2 AH packages.
I intend to use three of them to provide about 15 volts for my rig.  I
understand that there are battery charger chips that automate the charging
process, so that I don't have to be so concerned.  That is, with one of these
circuits, I should be able to build a plug it in and "sort of" forget it until
I need the battery again.  My question, does anyone have information about what
chips are available, and where I might go to get more information.  Any help
would be greatly appreciated.

( I use my scope, and a 51 ohm resistor, then figure from the RF volts
  that I get, the power: E^/R = W      ( ^ = 'squared')    )

This was the 80 mtr ckt... changed to give 40 a try....and later will
see if I can make it hit both bands.

Tune-up requires you to go for cleanest signal, which is just a hair
less mesh on C1 ( so same for 80mtrs ) than the point where it won't
key right...
Starting at full mesh, and open C1 slowly til she takes off,
will usually land you just where you need to be.

C2..added to let me move up-freq (onto marked freq of xtal !) while on 80m,
lets me move 900cps on 80M  and almost 1200cps on 40M.
That trick let me dodge the carrier ON 7110, from some BCB station.

 I'll be on this thing this week ,daytime (obviously!) on 40M , and may later
try 80M in late afternoons, evenings and past my midnite, as my work sked
permits.

I do not plan to neatenize the rig....as its on a pegboard (GIANT perfboard)
and intended to be buildable out of odd-ball parts,(rather than G-10 pcb
and all that hard to get stuff)...like using T-paper tubing for coils, and
a hunk of shingle for a PC board...hankybox cabinet....

I still await my FRS order, to make the 6AG7 xmit ( which will sorta replace
this one), so is why I persue this still.

I just got a Radiokit flyer, in which they advertise their QRP-15 and

my grep is not working properly).

So, who can tell me something about these devices?

Ted,

Maxim Integrated Products, Inc., makes what you are looking for.  I
cannot tell you specifically which chip you need.  However, Maxim
publishes a Battery Management Book containing 58 designs which they
claim were built and tested good.  Here is their address, etc.:

I don't think they will charge for the book.  Good luck on your project!

Well, from the description it sounds like an MFJ that has the audio
filter built in and not optional in a smaller case.

I ordered a 20 meter version yesterday and will let everyone know more
when I get the kit.

I am looking for input on the Tejas Backpacker II tranceiver.  It was reviewed

I plike the idea of 200khz tuning range although I was looking

To the qrp group:

A question. I am about to build a 4 to 6 watt amp,
the design of which comes from page 61 of the Solid State Design book
by the ARRL. They call for a GE D446C transistor, and suggest a 2n5321
as a replacement worth experimenting with. Well being very new to this
hobby I am not sure if the design of the amp is highly dependent on
the characteristics of those particular devices or can I substitute
another device. If any of you are familiar with the amp design please make
some suggestions for replacement transistors for me.
Thanks

Subject: Crystal Testing Request


I am looking for someone who has built Doug DeMaw's Crystal Tester (Jan. 1990
QST)
and who might be willing to test ten 10.24mhz crystals I have  (got them
cheaply).  I would be both grateful for any assistance and will pay for all
shipment costs (plus a small compensation for your time and troubles).  The
reason I am posting such a request is because I am building a superhet receiver
(Nov. 1983 Ham Radio) and would like to have a multi-pole IF crystal filter;
however, I lack a frequency counter and o-scope at the moment to test the
crystals (though maybe Santa will be nice to me this year? ... yes? :>  ).
I would be extremely grateful for any assistance.

Thanks!!

Subject: Re:  Battery charging chips - looking for help.

You can build a simple NiCd charger with 3 parts (78xx regulator, capacitor and resister).

Wire it as shown below.

                           .................
                       Vin .               . Vout
           +    ............    78XX       .......
                    .      .               .     .
                    .      .................     .
                   ...           V .ref          .
                   ... C           .. /\/\/\/\........+
                    .                     R
                    .                                To Battery
                ......................................
           -                                          -
In this configuration, the 78XX regulator is a constant current source. The
current to charge a NiCd is typically 10% per hour of its full amp-hour cap-
acity. It will take 12 hours to charge a NiCd on this basis due battery losses.

In your exapmle (A 15V 2A NiCd), use a 7815 regulator and set R to produce a
200mA constant current. R = 15V / .200A = 75 ohms. From I^2  x R, R should
be able to handle over 3W. C is a .33uF capacitor. Just connect the above
circuit to a DC power source that can provide a couple of volts more than
the voltage regulator chossen.

May I add, that a diode should be put between the regulator and the battery
so in case the power (AC) fails, the battery won't try to drain back and
blow out the chip?

Yep, you read the heading correctly.  One NorCal 40 assembled, rather
nicely I might add.  $100 firm and that does include shipping.

No mods and no painting done to case.

Reason for sale:  too many rigs and the K5FO Special is a done deal (at
least the prototype is working to my satisfaction).  I'm checking my
mail several times a day, so don't expect immediate response to any
inquiries.  Order in which I receive the mail takes precedence.

This is the rig everyone has been raving about on the west coast and
also some on the east coast.  Someone has posted the specs previously.

I'm working on another posting for tomorrow or later tonite.

Actually the input voltage must be at least the desired battery voltage plus
the basic regulator voltage plus about two to three volts overhead for the
regulator.  For Ed's case of a 12 cell Nicad, i.e. 15 volts, the input voltage
would need to be greater than:

    15 +  5 + 3 = 23 volts for a 7805 regulator which dissipates
        0.6 watts for a fully charged battery increasing to
        3.6 watts for a fully discharged battery and the
        resistor will dissipate 1 watt,

    15 + 12 + 3 = 30 volts for a 7812 regulator which dissipates
        0.6 watts for a fully charged battery increasing to
        3.6 watts for a fully discharged battery and the
        resistor will dissipate 2.4 watts,

    15 + 15 + 3 = 33 volts for a 7815 regulator which dissipates
        0.6 watts for a fully charged battery increasing to
        3.6 watts for a fully discharged battery and the
        resistor will dissipate 3 watts.

This is because these regulators maintain their respective voltage between
their output pin and their common pin or reference pin.

A better regulator choice would be the LM317 regulator which maintains
approximately 1.25 volts between its output pin and its adjustment pin.
For the same 200 mA charging rate to the 15 volt battery, the resistor
value is 1.25/0.2 or 6.25 ohms which dissipates 0.25 watt.  The input
voltage will need to be at least 19.25 volts.  Once again the regulator
will dissipate 0.6 watts with a fully charged battery and 3.6 watts with
the battery fully discharged.

It can be seen from this that the higher voltage regulators need higher
input voltages and that the resistors dissipate much more power with the
higher voltages.  LM317 regulators are slightly more expensive than the
fixed voltage regulators and the 7805 regulator is probably the least
expensive at hamfests.  From a cost standpoint (we QRP'ers are cheap!),
a 7805 regulator, a 25 ohm 2 watt (safety factor of 2) resistor, a small
heat sink and a 24 volt power supply would suffice.

Subject: QRP and my car's battery


Hi all,

Does anyone have experience powering a qrp rig from their
car's battery? While the car isn't running? Due to evil
condo covenants, my best bet for a good antenna and operating
site seems to be to drive to the top of a hill and set up
my vertical.

I figure I could save some money by using my car's battery
instead of buying a gel cell, but I'm not sure if the drain
would be too much for it. I know you need one of those "deep
discharge" batteries for higher-power use, but since I'm
operating qrp cw I'm hoping that doesn't apply here.

Any thoughts?

73,

Well, Joe....this might be one for the famous QST author (and authority)
Jeff Gold.  He thinks about this stuff, and has done quite a bit of QRP
mobiling.  I have operated QRP from my car with my Argonaut much like
Jeff describes in his article.

In my own experience with the Argonaut (and a few simpler rigs), that
draw less than 1 amp on transmit, most car batteries can handle it all
day....or longer.  I suspect you can calculate how much of 1 amp
intermittent drain the common car battery can handle, but suffice it
to say that I have done it for 3, 4 hours or more with absolutely no
problems.  I operated field day with a small spare car battery that I
use when my installed car batteries fail.  I used it for the whole time
with my Argonaut, SSB, probably 10 hours or more.  When I took it home,
I used it to start a car.  It is NOT a special battery, and is not large
or expensive.

Good luck.

Clark

QRPers:

Thanks to all who have responded to my previous questions about varactors
in VFOs and suggestions on kits to buy. My Christmas wish list will be
all the better for your information.

I have come across a source for some relatively obscure items:
DC Electronics, PO Box 3203, Scottsdale, AZ 85271-3203
800-467-7736
800-423-0070
602-994-1707 FAX
602-945-7736 Local

I have the 1992 catalog, but I just called them and many of the prices
have not changed since then. Among other things, this place carries
the coveted SBL-1 balanced modulator ($6.95). Also toroids, NE602, and
various PLL, VCO, and Rx subsystem ICs. A very nice selection for
homebrewers. Minimum on phone orders "nominally" is $15. No min
on prepaid orders. Credit cards OK ($15 min). I always seem to get the
same gentleman on the phone each time I call; he is helpful and knows
the stock, but he would not win the Mr. Congeniality award.

Has this place been mentioned here before?

Yea, I opperate QRP mobile all the time because of some of the
considerations you mentioned.  If your Alternator is bigger than
50 Amps, and your Battery is a Delco bigger than 750CCA, you will
have no difficulties opperating for 8 hours+ without starting
the car.  QRP mobile is great!!!

Well, I operate of hours at lunch periods and on tops of mountains with
my 509 argonaut.. both CW/SSB and have no problem with the car off.. I
also use a small 4ah gel cell that I picked up at a ham fest for $5.00
and that will run for hours with my small CW transceivers.. I have gone
for days with the 7ah battery.

Many times in the Smokeys I will have a few QRP transceivers in a case
and bring my portable PVC vertical and pull over and operate using a
small gel cell.

Hi gang,


I has recenlty given a HW-7. I traded it for an OLD PC XT. The guy that gave
it to me said it would make for a good cabnet for some project. I hooked
it up and turned it on, It seems to work great, or as well as they ever
did. Lots of microphonics in the receiver. Transmitted works good.

Does any one have or know were I can get a schematic and/or know of any
modifications that were published for the rig. I would like to tinker
with it and see if I can improve it any.

Also came upon a larg cash of parts , from what I think was a power
supply for some  kind of electronic equipment being thrown out ,
two large transformers  12, 8 and 18 volts, three heat sinks and several
LARGE  Capacators and some Motorola transistors, (voltage requlators I think)

#  MC7812CK    I think a 12 volt reg.

  MJ802

  MJ4502

  Does any one know what these are,and do you know where I can find
  data sheets on them. I cant find them in my NTE cross reference.

  Any help would be welcome.



Thanks

   Time to tap into some of that QRP expertise out there on the net.....

   I need some help with a simple 20 meter NE602/LM386 direct conversion CW
receiver that I built.  The receiver seems to receive only a few
strong signals and many weak signals.  I can easily zero beat the strong
ones, but not the weak ones.
   The weaker signals all seem to have the same very high audio frequency
( I guess about 1500-2000Hz ). I assume that the weaker signals
are real twenty meter CW signals.  They sound real.  I'd just like
to be able to hear them at a much lower audio frequency.  (No, I don't
have an audio filter, I haven't built that yet!)  When I try to tune
them in, they just disappear.  They're just at that one spot on the dial,
and very high pitched.
   Is this a common DC receiver problem?  What might cause the receiver
to do this?  What should I "attack" to try and solve this?
A bigger, better, higher antenna?  Different headphones?  A speaker
instead of headphones? Some bad component in the receiver?  Change the tuning
method (from varactor diode to air capacitor)?  What thing is most
likely to be the problem?  I don't really know where to start.

I say:

    The MJ802 and MJ4502 are 150-200 Watt silicon power transistors that
are useful from DC to a couple of hundred Khz. They are a complementary
pair, but I don't remember which is NPN and vice versa. I can dig up the
information over the weekend. In general terms, the VCBO is around 90V,
and ICsat is ~25A, though you wouldn't want to operate at those extremes.

    Southwest Technical Products Corp. (SWTPC) introduced their "Universal
Tiger", a 100 watt audio power amplifier, in the early 70's which used these
parts in the output stage. I remember frying a few pairs of these then
expensive devices since the amplifier's design was less than ideally stable
and it would occasionally go into rf oscillation.

***********************************************************************
To the qrp group:

A question. I am about to build a 4 to 6 watt amp,
the design of which comes from page 61 of the Solid State Design book
by the ARRL. They call for a GE D446C transistor, and suggest a 2n5321
as a replacement worth experimenting with. Well being very new to this
hobby I am not sure if the design of the amp is highly dependent on
the characteristics of those particular devices or can I substitute
another device. If any of you are familiar with the amp design please make
some suggestions for replacement transistors for me.
Thanks

Things aren't as critical at HF as they are at VHF and UHF.
Buy/beg/borrow/steal a transistor data book and have a look. You want to
match or exceed the D446C's dissipation, get reasonably close on its beta
(Hfe), get the capacitances reasonably close, and match or exceed (but not
by too much) ft. Make sure the various breakdown and bias voltages are
reasonably close, and try it and see.

Try not to spend too much for the transistor you use, so you won't be out
too much if you blow it up.

Matching or exceeding the dissipation is self-explanatory. Matching beta and
ft makes sure that you have the right gain at the right frequency, so that
the amplifier remains as stable as the original. Ditto the capacitances to
get impedances and feedback right.

W1FB's Design Notebook is another good reference on this and many other
issues.

While we're talking about books, any suggestions on a good place to buy
goodies like those Motorola RF devices data books everybody keeps referring
to?

Gang, we have been able to obtain 50 matching cases for the NorCal 40.  It is
just like the original, but there are no holes drilled in the front and back
plates, so you can use them for matching keyers, tuners, power supplies, or
whatever.  These cases cost us $10 each, and the NorCal Club is providing the
spacers and special screws.  They are made out of .060 aluminum and really
hold up well.  To order send $10 plus $2 shipping and handling to:

these cases and that is why I am posting it here.

Hi all,

Hope you had a good weekend. I had a REALLY hastled week last week, so
decided to take a break from building, writing and fixing (except for
putting together a Quad for a friend).

I hooked the Norcal up to a battery, then hooked up a Vibroplex bug. I
love straight keys and use paddles, but never played with a bug. The bug
is definetly a different kind of animal. Takes a little getting use to.
Had to put a counter weight on the pack to get it to respond slow enough
so that I could send in a manner that other could understand.

The Norcal was putting out about 1.8 Watts (the battery wasn't charged
up). The bands in my area were horrible, lots of noise even on 20
meters. Kinda challenging conditions for QRP. I was once again amazed.
the first cause of amazement was that I was able to get to the point
where I could carry on a QSO using the bug.. liked it a lot. The second
cause was that little old transceiver.

The Norcal is the smallest of all the transceivers I have built. Only
worked with one smaller, Doug's NN1G in a teeney weeney case.. just big
enough for the 2 boards.. have no idea how he crammed everything in the
case, but you can store it in your pocket. The next up rig I have is the
MFJs.. and the Norcal is significantly smaller.

The Norcal kinda reminded me of the MFJs in a way, but had some things I
liked better. I made over 20 contacts as I remember. The amazing thing
was that most of them were with guys running Japanese commercial rigs
such as Icom 745s, Kenwood 850s and such.  A good portion of them
reported that the noise level in their area was so bad that they were
going to go off the air.

OK, now if the Norcal was putting out a signal that was just in the
noise level, I could understand, but that wasn't what was reported. I
got good signal reports, most around 559, but they were having bunches
of trouble with the noise factor. I could hear a lot of noise on the
band inbetween signals, when I tuned in a decent signal (449 or better)
I just heard the signal, no noise, or not enough noise for me not to
have a perfect copy. That is saying a bunch.. pretty impressive.

I checked out my MFJ afterward and one thing that really jumped out at
me was the switching. I hadn't really been bothered by the relay
switching in the MFJ before, but after spending  the weekend with the
Norcal, the relays annoyed me to no end. The changoever time for
switching in each rig was about the same.. boy do I prefer the Norcal.

Think the Norcal would make an excellent commercial rig.

Hi Gang,

I have an HW-8 and the Hotwater Handbook, so I have started the mods
to make that radio more functional.

I recall that there were two other sources of improvements. One was called
"A Super-Modified HW-8 Contest Machine" (sic) and I believe it appeared
in QST and was authored by Doug DeMaw (a guess). The other was a series by
Ade Weiss, title unknown.

If anyone can provide me with leads to acquiring either of those articles,

Several people asked about the weekend contest (what the heck WAS that
contest, BTW?) and propagation.

I spent a little time yesterday on 10M.  Early in the day, around noonish,
it stunk.  Propagation from my QTH (central Indiana, apartment, antenna
in attic) didn't exist.

I tried again around 5 PM and was rewarded with the band seeming to be
fairly open (for about the first time this fall that *I* have heard).

And oddly enough, instead of the usual afternoon-to-the-west-only
propagation, I also was hearing from the northeast (Maine, New York,
New Jersey basically all of New England), the near south (both
Norht and South Carolina) and VERY oddly, both Ontario and Quebec, Canada.

I have NEVER, EVER worked Ontario or Quebec from my QTH before this
weekend.  I get lots of VE5, VE6 and VE7 (mostly VE7).

There was the usual s***load of California stations.  :-)

I heard some from the US Northwest but not a lot.

A further oddity was that very little was heard from the southwest
direction.  Not a single Texas, Arizona or New MExico did I hear.  Did
hear one Louisiana.

Band was pretty good until about 2330 UTC or so, and then the bottom
pretty much fell out in a matter of about ten minutes.  After that
there'd be the occasional fade-in, fade-out but no real decent signals.

10 meters is decidedly following the down-trend in the sunpsot cycle that
has been predicted.  I can't even recall the last time I heard a
station from Japan.

(And I really NEED a Japanese station with a 10-10 number, so I can
use Asia to complete my 10-10 Worked All Continents award)

I did hear some medium-short skip from Pennsylvania.  I oculd use some
SHORT-short skip from Ilinois, Michigan and Ohio.  Those are the only three
states I need for 10-10 Worked All States.

Well, what the heck.  I only need a few more countries to get the basic
10-10 Countries Certificate, for working 10-10 members in 25 countries.

All this on about 10 watts.  Who says you need big power to work DX?
Humbug!  :-)

Now, we got any Michigan, Illinois or Ohio 10-10ers on this list???????  :-)

 [e-mail] posed the question,

"Incidentally, what is a 10-10 award?"

Weeeeeell, I guess we can take a stab at that.  :-)  10-10 International
is an organization that you might say is dedicated to the use and
preservation of Ten Meters.  Most everyone knows that when ten is good,
it can be outstanding.  It is just as true that when it isn't so good,
it really sucks!


Anyway, 10-10 sponsors some 10-meter contests for both CW and phone.
There are also awards, which I alluded to in a previous mailing.
There are the usual awards, like Worked All States, Worked All
Continents, there is a Countries award with a basic certificate starting at
25 countries.  There is a Worked All US Counties award, and one
member just recently was awarded certificate #1.

Keep in mind that these awards require you to work other 10-10 members,
not just any ham.

So when K6SIW was awarded certificate #1 of the Counties award, he had
worked 10-10 members in something like 3076 counties!  I think 3076 is the
right number, I know it is pretty outrageous......

I believe that the basic counties award is 100 counties.  You go up from there.

There are other things, like the bar program.  For each 100 10-10 numbers
you work, you add another "bar".  At 500 there is a certificate called VP
(and sometimes called a few other things :-)  ), and you are issued a
separate VP number.  There are awards that are only open to VP members.

Another award that K6SIW is going after is the OM/XYL award.  The upshot of
this one is to work husband/wife 10-10 teams.

Uh.....there is a Worked All State Capitals award.  I'm sure I am
probably leaving something out.

The contest typically is to make as many contacts as possible.  You count
2 points for a 10-10 member, 1 point for non-members.  I had suggested
adding a point category for those working QRP, say 5 points for ops below
25 watts and maybe even 10 points for those below 5 watts.  So far I don't
think there has been enough interest for them to try it.  Of course, with all
you hard-core QRPers out there.......   :-)

It might be more interesting to run a separate QRP contest rather than
doing something that might must confuse the issue.

To join, you need to work 10 10-10 members, collecting their call, their
membership number, their name and QTH.  You will send this list plus
some cash, I don't recall how much....maybe it's 8 bucks for a year.....
anyhow, you send this to the manager for the call area you live in,
and he/she will get your certificate and card ready for you.  For your
8 bucks, you also get the quarterly newsletter.  Aside from interesting
stories about hams and so forth, the newsletter tends to have info. on
DX stations (like what address to send a card, etc.) plus all the dope
on the 10-10 contests and awards.

Once you get your number, it is your number for life.  Even if later you
decide not to renew your membership (gads! horrors!) the number is still
yours (and some folks use it in self defense when they are asked for it!)
and will count as a valid number for someone else who is hunting.

To date, something around 65,000 numbers have been issued.  Quite a few of
these are still active, and it seems like an increasing number of them
are DX stations.

I have done all my 10-10 work under 25 watts.  I'm three states off the WAS,
one continent off the WAC.  I probably have enough counties via QSL (or could
get them) for the basic Counties award, but I'm not too worried about
that right now.  :-)

I think I have 391 #'s worked, so I am close to the 400 bar, and hoping to
nail down enough for the 500 bar in the next phone contest in February.

Some guys have close to 25,000 worked, I think.  I believe that the
aforementioned K6SIW is either close to or at the top of the list in
this regard.

No doubt, it *IS* more difficult, the less power you use.  Running low power
during the phone contest borders on the masochistic....

I have been known to give my phonetic callsign, during this contest, as
"whiskey bravo nine one masochistic communicator", which is often good
for a laugh.

.....but even so, having worked this stuff at a reduced power level,
I feel that I have accomplished MORE than if I just went out and "bought"
my QSO's like so many other folks have.

Anyhow, something for y'all out in QRP land to think about.  Perhaps a
strong QRP surge in 10-10 would be good for it and induce some new
awards and/or contests.......

Rick, KF4AR, mentions adding 17 and 12 meters to his Argosy,
by replacing the two high 10-meter positions. I have been
considering this same mod on my Argosy. It should be possible,
by reworking the xtal oscillator tanks, and running jumpers
on the bandswitch. If you do it, let us know!

The NorCal 40 is back!

Many of you--including NorCal club members--asked about the NorCal 40 AFTER
we had already sold all 100 of the kits.  Since the response was so
positive, we've decided to do another batch of 100.

The first batch of 100 taught us a lot about doing a big club project.
Some of us went through two sets of tires and wore out our welcome looking
for bargains at surplus stores, which was the only way to keep the cost low
enough to offer the kits for $75.  This time, we're going to keep our
social lives intact and buy almost all of the parts new, and consequently
the price is going up $14.  This is still a bargain when you consider that
the NorCal 40 is a complete superhet transceiver kit, with custom case, all
controls and connectors, a really clean silk-screened PC board, and a
complete assembly manual.  (If the NorCal 40 becomes a commercial kit, it
will sell for $100 to $120 depending on whether or not they use slave/child
labor!  We can sell it for less because we have a bunch of retired guys
doing the kitting who promised thier wives exotic vacations after this is
all over.)

If you're interested in a NorCal 40 kit, call Jim Cates at 1-916-487-3580
or write to him at 3241 Eastwood Road, Sacramento, CA  95821.  He'll let
you know if there are any left and reserve one for you, at which time you
should send him a check (in his name) for $89 plus $4 shipping/handling.

If you're not a NorCal Club member, you'll make Doug Hendricks an even
happier guy than he usually is by including another $5 to join up and
receive the next issue of the NorCal journal, QRPp.  Doug does a great job
on QRPp--the last one was around 60 pages!  You'll get plenty of QRP tips
including ideas for modifying the NorCal 40.  (Some club members have
modified thier NorCals to put out 5 watts and cover the whole 40-meter CW
band, notably Bob Warmke, W6CYX.)

Again, remember to make the check out to Jim Cates, NOT me and NOT NorCal.
Note:  This is a club project, and all surplus receipts, if any, will go
towards NorCal club activities and future projects.

If you missed the original description of the NorCal 40, here's a reprint.
Please forward this letter to others who aren't on Internet who might be
interested.

NorCal 40 Transceiver Description

The NorCal 40 is a compact 40-meter CW transceiver optimized for ease of
assembly and use.  It is particularly well suited to portable,
battery-powered operation, with very low receive-mode current drain.  To
make assembly as easy and trouble-free as possible, all components,
including the controls, connectors, and even the case parts are mounted on
a single printed circuit board.  There is virtually no chassis wiring.
Alignment is similarly easy, and can in many cases be done with no test
equipment, or with only a separate transceiver that covers the 40-meter CW
band.

The receiver is a superhet, providing good sensitivity, selectivity, and
freedom from 60-Hz hum pickup.  The 4-pole crystal filter offers clear
single-signal reception, and a simple differential JFET AGC circuit is used
to keep strong signals relatively constant.  An RF gain control is provided
to attenuate extremely loud signals.  The conversion scheme used results in
a stable, low-frequency VFO (variable-frequency oscillator), operating at
about 2 MHz.

Operating features include RIT (receive incremental tuning), solid-state
Transmit-Receive switching, transmit signal monitoring, and variable power
output up to about 2 watts.


Specifications

(Note:  Numeric values given are typical.)


General

Size:                            2.2" (H) x 4.6" (W) x 4.5" (D)
Power Requirements:              10 to 15VDC; reverse-polarity protection
Receive:                         15mA typ.
Transmit:                        200mA typ. at 2.0 watts output
Tuning Range:                    Any 35 to 40 kHz portion of 40 meters
VFO:                             2.085MHz at RF = 7.000MHz; 10 to 30 Hz drift
                                      from cold start after one hour

Transmitter

Output:                          500mW to 2.0W, adjustable
Final amp efficiency:            75%
Load Tolerance:                  brief operation into high SWR or open
Transmit offset:                 500-700 Hz
T-R (transmit-receive) delay:    200 milliseconds

Receiver

Sensitivity:                     Better than 0.5uV for 10dB S+N/N
Selectivity:                     400Hz @ -6dB, 1.5kHz @ -30dB

Audio output impedance:          8 to 32O (headphones only)


Quirks and limitations:

- there isn't enough AF output to drive a speaker--just headphones;

- the AGC range is limited (JFETs go nonlinear at some point) and you have
to choose one of 3 supplied resistors during alignment;

- as with all NE602-based receiver designs, you *will* need the RF gain
control once in a while;

- the VFO tuning range is only about 40 kHz using the varactor diode
(presenting one of many opportunities for modification);

- there is a small "birdie" at 7.023 MHz can be easily subdued with a
series LC circuit on the back of the board, as explained in the manual
(parts supplied);

- there is no I.F. amp--not really needed on 40 meters--so modifying the
rig for 20 meters or above isn't a good idea.   30 meters should work fine;
replace all 6 of the 4.915MHz crystals in the rig with 8.000MHz crystals.
80-meter mod is even easier since you can use the same crystals.


The rig was designed by Wayne Burdick, N6KR.  Please send mail to
[e-mail] for design details.

Subject: I hate to do this but . . .

I have a rarity. A radio by Don Stoner (yes, the legendendary Don Stoner)
that I need to sell.

Here is the scoop: this is basically a 12 watt ssb radio that covers the
voice portion of 40 meters. It was designed for missionaries, oil exploration
teams, and the like, so it is quite rugged. It was modfied by one of Stoner's
employees with a vfo which covers 7150 to 7300 KHz.

I have had this radio all over the place and it does fine as a mobile
or portable rig. I have the original manual but no docs on the
vfo, although it seems to be of a standard varactor design and has
proven to be quite stable. There is a front mounted speaker and volume control,
mic jack and earphone jack. The vfo dial now occupies the left side of the face.
There is plenty of room in the cabinet for all kinds of stuff. You could
probably fit in a 6ah gell cell.

If you are somewhat interested (not just curious), I will fax you the pages from the
manual that describe the radio. The photograph in the manual shows the radio in its
channelized form.

I'll sell the radio for $225 with the docs but without a microphone. I'll pay the shipping
costs and you may have it for five days to see if you like it. If you do,
I'll cash the check. If not, you ship it back to me.

There are no guarantees however the radio was working fine when I put it away about
five years ago. It is clean.

I called Jim Cates last night and reserved a new NorCal 40. He mentioned to me
that an upcoming issue of QRPp will contain articles on mods to this rig.
In addition to band changes and higher power output, there is also the
possibility of a digital frequency readout. ....
thought you all might like to know.

We have duplicate crystals ( ordered 2 each) so, he'll be on either..

3685-6  3699-700  3709-10  or  7109-10 kc....the rig can move +/- 500cps.

 As he is currently fixing his car ( roasted the starter moter ), he has no
time to fling solder...and in his free time he'd rather be on the air...and
so I get to hear it...and I get to proceed on the NEXT madness:

6AG7 1 tube xmit...also about 1/2 watt I expect ( 175v B+)....for which I

Due to lack of wood/salvage, I've been drinking as much coffee as possible,
so as to empty that can....that nice empty can....easy to solder to.....

heh heh heh.

  The Sad Tale of a Musical Oscillator, Or how I'll spend my Xmas vacation

Well, what that silly first line was meant to allude to was the fact that
I have a chirping, whooping, and generally being anything but, stable
oscillator.

As CW is my preferred form of rf emission this chirping oscillator just
won't cut it.

Here are the specifics.

The rig is a TEN-TEC pm2 (early 70's qrp rig) It's a direct conversion
style transceiver. "The oscillator used for receiving operates directly at
the frequency being received. This allows the same oscillator to be used for
transmitting. When the XTAL/VFO switch is placed in the VFO position,
it connects the receiving oscillator output in place of the crystal."

This is a fairly crude design in my opinion.The DPDT switch has single
conductor hookup wire going from the switch to the board (six of them)
about 2.5 inches long. The switch selects between 80m and 40m lc circuits
which feed the base of  the bipolar transistor,  the oscillator.
The oscillator is followed by a buffer and then the XTAL/VFO switch.
After the XTAL/VFO switch is the driver stage and the final.

That's it on the radio

Soooo, what how about suggestions on improving the stability of the
oscillator. By the way there is no shielding around the transistor section
of the oscillator, the inductor is in a metal can but that's it.

Any suggestions  would be appreciated. I am going camping down into Mexico
and want to use my new (to me) VFO capable radio as opposed to my MXM
rock bound QRP rig.

Thanks in advance.

Coffee cans  Bean cans , are ( right now) the only ones...while tuna fish
cans are made of...Japanesium? ...some mix of 20 different metals, and it
acts like aluminum and stainless steel....can't solder it...
BUT ya can pick it up with a magnet...somwhat....and it will rust.

Some metals have a coating that has to be sanded (NOT wire-wheeled) off
to be able to solder to it.

Beer cans are aluminum...no way to solder that...and its too thin for any
but as a stick-on shield where the can only supports itself.

( I have a Contadina tomato paste can tube shield in the collins to ward
off heat from affecting the auto-key set up...like  a chimney...with holes
at the bottom to let in fresh air...can's diameter is enough so air passes up
along side the tube ( audio output) and out the screened top of cabinet)

If can is sanded after getting holes put in and all, it can be painted and
look almost like it was meant to be an electronic part....I had more home
wound xformers/ rewound ones that I 'potted' into bean cans and such....

Use rustoleum paint...not that yuccky latex stuff.

Go peek inside again...does the set have a regulator for the DC feeding the VFO?

If not...consider making up one...say... using a 7808 .

Adding a buffer stage ( MPF-102 as source-follower...1k source resistor,
100k gate, with 33pf to 100pf blocking caps )
will help , if its due to 'pulling'...

If the its a swoop rather than a fast to-weep, then I think its due to the DC
volts being dragged down a hair by the increased load of xmitting (is normal)

A regulator would fix that ( at the VFO).

If its a quick to-weep, then its pulling...a buffer stage is needed.

I haven't had much of a problem solder cans as long as I got the
spot hot enough (tin cans).

I once built a one fet LC oscillator on a tin can lid and then
soldered a round tuna tin over it (the lid was larger than the
diameter of the tuna can).  So this was completely sealed except
for the soldered in feedthrough capacitor for V+ power (case was
gnd).

The oscillator was audible on the receiver (ie: not completely
shielded).  This was about 20 Mhz.  It was also possible
to hear the frequency shift as the can was squeezed.

All in all, I'm not that excited about tin cans...

PS: I'd guess most (all?) of the leakage was via the feed through
    capacitor.  The power available inside the case was at most
    10 mW, however the minimial detectable leakage would probably
    be around -150 dBm which is much much less than 10 mW (+10
    dBm).

I once used a small can of varnish ...pouring it off into a coffee can with
a rubber lid first... to make a mini dummy load.

The push-on lid held a SO-234 ( soldered it on with QRO solder-iron  P.U.!)

SO-234 's center pin supported 3 150 ohm, 2 watt CARBON COMPOSITION *
 resistors, and their other ends went back to the SO-234's shell (on inside)

The 3 150's make for 50 ohms...rated 3 watts REAL diss, and was RF tight
enough to not pin the S-meter if xmit was shielded well.

Then, I made a 2nd one, for 75 ohms...same as above, but 2 watts real rating


I later added mineral oil and made a big slippery mess.  pleh!

*** Ed, I used to have one of those.  In my estimation, the thing chirps
because of

   1) Changing output load on the oscillator in transmit as compared to
      receive.

2)  Instability on the power bus.

  What I would do first, is to put an emitter-follower buffer between the
  oscillator output and everything else.

  If that didn't do it, I'd see about improving the supply voltage regulation
to the oscillator.  A zener diode and a resistor would help isolate the
oscillator supply from everything else.  Of course, you would lose a bit of
oscillator output.  Replacing the emitter follower with something with a bit
of gain would compensate.

   The main problem I had with my Power-Mite was AC hum pickup.   A zero-gain
buffer ( boy do I love those emitter-followers! ) in the antenna input path
fixed it right up.

You haven't made it in our club as a QRP expert until you solder a beer can!


First... get a soldering GUN.  Clean a spot on any aluminum beer can.
Put a drop of oil on the clean spot, and heat hot with the gun.  Then
once hot, tin with regular solder, then put the wire on the can! Walah!!!

No this isn't a joke, I've done it with wire bradi, and it held so strong that
when I finally pulled it off the beer can it ripped a hole in the side.

Now, I will say that I have done this consistently, but many have tried, and
not succeeded!  The trick to it is, first empty the beer can..

Comment: MEMO 1993/12/17 07:58


It appears that several people did not get this as questions keep coming up.
So, here it is again.  Specs are at the bottom.
I called Jim Gates and got on the list.  I forgot to ask him when they
expect to have the kits ready.  Does anyone know?

Jan  WA4VQD   [e-mail]


The NorCal 40 is back!

Many of you--including NorCal club members--asked about the NorCal 40 AFTER
we had already sold all 100 of the kits.  Since the response was so
positive, we've decided to do another batch of 100.

The first batch of 100 taught us a lot about doing a big club project.
Some of us went through two sets of tires and wore out our welcome looking
for bargains at surplus stores, which was the only way to keep the cost low
enough to offer the kits for $75.  This time, we're going to keep our social
lives intact and buy almost all of the parts new, and consequently the price
is going up $14.  This is still a bargain when you consider that the NorCal
40 is a complete superhet transceiver kit, with custom case, all controls
and connectors, a really clean silk-screened PC board, and a complete
assembly manual.  (If the NorCal 40 becomes a commercial kit, it will sell
for $100 to $120 depending on whether or not they use slave/child labor!  We
can sell it for less because we have a bunch of retired guys doing the
kitting who promised thier wives exotic vacations after this is all over.)

If you're interested in a NorCal 40 kit, call Jim Cates at 1-916-487-3580
or write to him at 3241 Eastwood Road, Sacramento, CA  95821.  He'll let
you know if there are any left and reserve one for you, at which time you
should send him a check (in his name) for $89 plus $4 shipping/handling.

If you're not a NorCal Club member, you'll make Doug Hendricks an even
happier guy than he usually is by including another $5 to join up and
receive the next issue of the NorCal journal, QRPp.  Doug does a great job
on QRPp--the last one was around 60 pages!  You'll get plenty of QRP tips
including ideas for modifying the NorCal 40.  (Some club members have
modified thier NorCals to put out 5 watts and cover the whole 40-meter CW
band, notably Bob Warmke, W6CYX.)

Again, remember to make the check out to Jim Cates, NOT me and NOT NorCal.
Note:  This is a club project, and all surplus receipts, if any, will go
towards NorCal club activities and future projects.

If you missed the original description of the NorCal 40, here's a reprint.
Please forward this letter to others who aren't on Internet who might be
interested.

NorCal 40 Transceiver Description

The NorCal 40 is a compact 40-meter CW transceiver optimized for ease of
assembly and use.  It is particularly well suited to portable,
battery-powered operation, with very low receive-mode current drain.  To
make assembly as easy and trouble-free as possible, all components,
including the controls, connectors, and even the case parts are mounted on
a single printed circuit board.  There is virtually no chassis wiring.
Alignment is similarly easy, and can in many cases be done with no test
equipment, or with only a separate transceiver that covers the 40-meter CW
band.

The receiver is a superhet, providing good sensitivity, selectivity, and
freedom from 60-Hz hum pickup.  The 4-pole crystal filter offers clear
single-signal reception, and a simple differential JFET AGC circuit is used
to keep strong signals relatively constant.  An RF gain control is provided
to attenuate extremely loud signals.  The conversion scheme used results in
a stable, low-frequency VFO (variable-frequency oscillator), operating at
about 2 MHz.

Operating features include RIT (receive incremental tuning), solid-state
Transmit-Receive switching, transmit signal monitoring, and variable power
output up to about 2 watts.


Specifications

(Note:  Numeric values given are typical.)


General

Size:                            2.2" (H) x 4.6" (W) x 4.5" (D)
Power Requirements:              10 to 15VDC; reverse-polarity protection
Receive:                         15mA typ.
Transmit:                        200mA typ. at 2.0 watts output
Tuning Range:                    Any 35 to 40 kHz portion of 40 meters
VFO:                             2.085MHz at RF = 7.000MHz; 10 to 30 Hz drift
                                      from cold start after one hour

Transmitter

Output:                          500mW to 2.0W, adjustable
Final amp efficiency:            75%
Load Tolerance:                  brief operation into high SWR or open
Transmit offset:                 500-700 Hz
T-R (transmit-receive) delay:    200 milliseconds

Receiver

Sensitivity:                     Better than 0.5uV for 10dB S+N/N
Selectivity:                     400Hz @ -6dB, 1.5kHz @ -30dB

R.I.T. Range:                    +/- 2kHz at center of VFO tuning range
Audio output impedance:          8 to 32O (headphones only)


Quirks and limitations:

- there isn't enough AF output to drive a speaker--just headphones;

- the AGC range is limited (JFETs go nonlinear at some point) and you have
to choose one of 3 supplied resistors during alignment;

- as with all NE602-based receiver designs, you *will* need the RF gain
control once in a while;

- the VFO tuning range is only about 40 kHz using the varactor diode
(presenting one of many opportunities for modification);

- there is a small "birdie" at 7.023 MHz can be easily subdued with a
series LC circuit on the back of the board, as explained in the manual
(parts supplied);

- there is no I.F. amp--not really needed on 40 meters--so modifying the
rig for 20 meters or above isn't a good idea.   30 meters should work fine;
replace all 6 of the 4.915MHz crystals in the rig with 8.000MHz crystals.
80-meter mod is even easier since you can use the same crystals.


The rig was designed by Wayne Burdick, N6KR.  Please send mail to
[e-mail] for design details.

Ok, now that we all know that you can solder a beer can, how about making a
round p.c. board with a qrp circuit on it, and soldering it into a beer
can.  This would help with rigidity of the beer can, and it would be nicely
rf shielded. Then you can write it up for QST.

73 All, have a happy qrp holiday, I'm out of here till next year.

Is it important WHEN you empty the beer can?  For example, do you need to
empty it just prior to attempting to solder to it so that you'll be in the
right frame of mind?  If so, then will emptying 2 or 3 make it even easier
to solder to first one?

I just had to ask...

 I take it, you mean engine oil?

...and yes, by all means, remove the beer first!

I take it , too, a soda can (of which there are more of around here) would
do as well?

I had read in Popular Science/Mechanics...1960's(?)...that one can solder
aluminum....the article was about making an out-door lamp.

Using a glass-fibre(?) brush, to work-in the solder, it would stick....thus
tinning the 2 metals...then the 2 were sweat soldered like you'd do a
copper pipe-joint.

The oil part...hmmm...sounds like whats going on is that it keeps air from
getting at the 'exposed' aluminum....liquid TIG or MIG welding !

Contadina Tomatoe Paste cans...quite small..1.75 oz I think....make for
great, solderable IF and RF xformers.....is what I used them for to replace
wooked ones in old, too-far-gone-to-restore-to-classic-condition,-but-good-to
-use-and-SWL-with radios.

Those APC series trimm caps just fit neatly, and space to stick in a coil
under it...to make a tank ckt with.

All my cans, I've used like that, I'd either paint ...or tin with solder...
as the metal rusts fairly quick....

Had a solder-pot...and I'd save all my spent solder..any removed during a
rebuild..and remelt it...skim off the glop on top and just prior to a dip,
I'd smear flux on the can ( or other victem)...plunge and duck the stink.

OSHA would LOVE me!

Reply-To: [e-mail]

I am curious as to how rigs work with lower power supply voltages.  I am
planning of building a small rig for a 50 mile back packing trip next
summer.  In the past I have had trouble with transmitters becoming
unstable or unclean when the battery voltage declines.  I am planning on
using alkaline cells because I believe they have the greatest energy
density.

What I propose is for some of you to hook up your favorite qrp rig to a
variable bench supply and then measure power output and supply current
versus supply voltage.  Also, note when any irregularities occur
(instability, etc).

Any takers?

Thanks and 73.  Lowell

    I've often been asked questions like "How much will .5 dB in coax

There are a lot of anecdotal answers floating around but I think many of
them are wrong.

    To try to get some better answers I did a little data analysis
exercise using results from the recent CQWW cw contest. Whether or not
you're interested in contests, a contest is a good place to get data;
lots of stations with different configurations making lots of QSOs.
Results and station descriptions are usually posted to Internet so I
had lots of information to play with. I made a graph with one axis (x)
as the effective radiated power (in dB relative to 1 watt into an
arbitrary dipole), ERPd.  The other axis (y) is the total number of
QSOs made. Both scales are logarithmic. On this graph I plotted four
points -- representing the winners in each of three categories: high
power, low power (150W), and QRP, and the results for my station. I
assumed the three winners used the maximum power allowed in their
class. I estimated their average antenna gain by taking the gains of
their antennas on each band and weighting them based on what percentage
of the total contacts that band accounted for. For example, AA2U has
stacked 6-element tribanders on the upper bands, a 2-el on 40, and a
loop for 80/160. I estimated that this averages out to 10 dBd gain.

    The resulting data points were:
    Call    QSOs    Effective Power
              (ERPd watts)
    ------------------------------
    K1KI    2927         24000    high power
    K2ZJ    1292         2000    low power
    AA2U     734           50    QRP
    WB2CPU     234        3    me


    The points are surprisingly colinear. The only anomaly was that
AA2U, the QRP winner, was a bit over the line that connects the other
three. Since Randy often places in the top ten in the LOW POWER category
while running QRP, this is not unexpected. The line that resulted had a
slope of about 4 log power/log QSOs, i.e., it takes 4 dB of effective
power increase to increase your QSOs by 1 dB's worth. I won't try to
draw it here using ASCII characters, but you can start with a point
representing 1 watt, 300 Q's and draw the line to the right from there
with a slope of four.

    From this data I'm concluding the following:

    a. Getting rid of losses in coax, antenna switches, etc.
improves things somewhat, but not that dramatically. The line's slope
of 4 dB power per 'QSOs dB' says that reducing your power loss by 1 dB
would have increased your QSO total by about 10 ** .025 ==> 6%. A 2 dB
increase would give 12% more Qs, a 4 dB increase 26%, etc. While the
numbers are only specifically applicable for this contest, they
probably can be generalized to imply a success rate for working
non-contest DX or making readable contacts in general.

    b. While you're not going to be competitive with the big guns,
you can make a reasonable number of DX contest QSOs with QRP power and
simple antennas. In this contest the graph suggests that you could have
made over 400 QSOs with five watts and dipoles, and, 300 QSOs with just
one watt and dipoles. Since these numbers were derived mostly by
analyzing the contest winners, they represent the upper bound of what
could be done.
    It might be surprising that the line was linear over a very wide
power range, about 5 decades; from about 1 watt to tens of kilowatts.
Actually, my experience indicates that it may be valid even lower than
that, say down to .1 watt effective power.

    I hope this information provides a way of estimating the
performance effects of changing station characteristics and encourages
people to try working QRP. To save bandwidth here, I've described
things quickly. I'd be glad to elaborate or discuss other people's
thoughts on the subject.

Subject: it does work!

How much power do you need to work DX?  Not more than 2!  I worked ZL3ADX
tonight/this morning from Connecticut using nothing more than my OHR HP
QRP Transceiver and a G5RV at 65 feet on 40 meter CW.
My biggest problem in the QSO was terrible image problems in the DC receiver.
I have made one mod (adding a diode) to try and cut down on the image
problems from big SWBC stations, but from time to time, there's nothing
you can do.
