Subject: QRP SWR/Power Meter Kit - For Sale
The circuit is from the ARRL book "W1FB Design Notes" (page 173?).
Kit includes the printed circuit card and all new parts (including the panel
meter described herein) less an enclosure.
The panel meter is clear plastic with a black band at the bottom. SWR
is indicated at 1:1, 1.5:1, 2:1, 3:1 and by a red arc ifor > 3:1. Power
scales are 0 - 10, 0 -100 and 0 - 1000. Size is 2 7/16"W x 2 5/16"H.
The mounting hole is 1 3/4" diameter. The movement is 100uA.
This is an easy to build kit and will make a very useful SWR/Power Meter. With
the values in the circuit the circuit can be made for 0 - 1W, 0 -10W or 0 -
100W. Price is $35 shipped in USA.

Subject: Speed Limit
Gang,
Sorry, but i don't do 70wpm on 40 at nite. Too much qrm. High
speeds are possible on a lightly populated band. I do 20 to 25
wpm most of the time. In fact, I can tell you at what speed I
operate every qso. I record it in my log. The only nice about
the CK-2 and MM-3 and Heath Ultrapro Keyboard is that I know the
exact speed, one of the side effects of being in a digital world
of electronics. :-)
So don't be scared, I don't play burnout. When I was first starting
and I was up to about 40wpm, I had some W7 rip into me at high
speed, and to this day I don't know what he said. The ONLY qso
that this happened to me and the only one that will ever be that
way. Soapbox Off:-)
So, don't be afraid to ask me for a sked. I was on last nite
and got email from VE5VA that he heard me, but due to qrm, I
did not hear him. I was trying to find KI6DS, but propagation
to west coast never appeared. I did work XE2FO and AB4FO. I
heard W2FO on 30 meters a week ago, but he didn't hear me.
I'm going to novice band tonite and meet one of the guys on here
and then back to 7.040 area again. QRN about to die to reasonable
levels.
Back to regularly scheduled programming now in progress.
ciao,

OK, having done some more thorough research, I have narrowed things down to
three choices for a qrp kit. I am interested in what people have to think about
the following:
$75 NorCal 40 by the Northern California QRP Club
$109 Sprint by Oak Hill Research
$159 Gary Breed Transceiver by A&A Engineering
The NorCal 40 is more along the price level I'm interested in, but I am
wondering if maybe the Sprint or Gary Breed transceivers might be more
useful once built. If you had to choose one of the three, which do you think
represents the best value to a first time builder?
Another problem is that this wouldn't be purchased likely until February,
and the NorCal kit may no longer be available then...

Subject: straight keys? (was Re: Speed Limit)
Do you very many QRP'ers run straight keys anymore?
Running QRP with a keyer or a keyboard seems a bit
contradictory to me.
Am I just too old fashioned? I love CW but I started out
in the good ol' days when a bug was the latest. Hand sent
and hand copied CW is a bit of an art and challenge. Now
it appears the art/challenge is more in the contacts and contests
than in generaring dits-and-dahs.
I'd like to see SKN (Straight Key Night) be every month
rather than just on New Years's Eve. Last Sunday would be
fine. I'm going to suggest this to the rec...misc group.
...Dennis Henderson, N6TTW
ps: This isn't meant to be a flame. I've comtemplated
building a keyer but don`t have any time for operating
these days. This mailing group has got me thinking about
a QRP rig and perhaps a keyer as a spark for some renewed
interest.....

Surely not contradictory. QRP often implies simplicity, and sometimes
portability, but it only actually refers to low transmit power operation.
Inasmuch as a single chip keyer using CMOS technology may be constructed,
simplicity and portability are not necessarily sacrificied with a keyer.
Likewise, a notebook PC can be employed as a keyboard, which is also
portable.
In any case, straight keys ARE wondrous things (I collect them), and I
enjoy operating them. However, my carpal tunnel syndrome is much happier
when I use a keyer.
QRP CW is fine in any operating mode!

Dennis,
I only use a straight key - got a bug back in California that I might
bring back here to Hawaii on my next trip.
What's nice is to get proficient at using either hand to send with, so
if one cramps up just switch (that's hard to do with a bug, though).
Many times, just for fun, I use a straightened paperclip tacked to a block
of wood as my key; guess that counts as a `straight' key...

Subject: QSOs
Gang,
Someone in the group asked me a question and having thought about it,
I thought I'd give a few pointers. The rest of the group should join
in after this and let's put it all together in a neat package and
submit it to the QRPp and QQ. This is a joint venture, not a K5FO
special. :-) Your feedback is wanted and needed. Jump right in.
I am just relating my personal experiences here. Do you agree,
disagree, or don't care. :-)
QUESTION: What do I do to up my qso rate, either QRP or QRO power levels?
ANSWER(s):
1. Check your transmitter for clean signal. If possible, transmit into
dummy load and listen on nearby receiver. Is signal something you
would listen to during a QSO? No chirp, no key clicks, and no AC
components are desired.
2. Try listening to band first. Are signals good and at all levels?
If all the signals are weak and at about the same level, then
band is probably not in good shape for QRP. You're hearing all the 100W
stations just above the noise level.
If you hear really loud signals as well as weak signals, then QRP
levels will work.
3. Try to call a station that is sending CQ and is pretty loud, 579-599.
a. If this station is sending a long CQ (see following part 4), I'd
hesitate to go after the guy/girl, because they may have attracted
a crowd and you'll be fighting some stronger stations.
b. If they are sending a short CQ, you have a good chance. No crowd
is likely.
4. If you must call CQ, then do the following:
a. Find what you think is a clear frequency.
b. Send one time at 20 wpm 'QRL?'. Nothing else. Wait and listen.
i) If you hear a dit dit, R, or C, then a QSO is in progress.
Move on. DON'T send anything else. I've heard guys send
SRI, OK, and other stuff. It's busy, leave it alone. You
did your part.
ii) If no reply, then do it again. QRL? and wait. I do this
three times in a 10 to 15 second period. I'm in no hurry.
No use trying to start a QSO where a net or other QSO is in
progress. It will not win you any friends to try otherwise.
c. OK, we have determined that we have a clear frequency. Time to
go out in the woods and scare up the bears.
do it: CQ CQ CQ DE K5FO K5FO K5FO K
This is known as a 3x3 call. Nothing more and nothing less will
do. I guarantee you don't need more. If you do longer CQs,
you will either draw a crowd or you will tick everybody off and
they will move to another frequency. I have listened to someone
call CQ for about 20 seconds and still be going when I tune away.
How long are they going to send?
Now the hard part. LISTEN. Do you have a receiver and it IS the
most important part of the ham station. Without it, you're not
going to have much fun. Listen for the weak signals. It's me!!
OK, no answer do it again. Keep trying this about every 15 seconds
or so. If you have RIT, tune to either side. I've found that
sometimes I have someone calling me as much as 2KHz off where I'm
usually listening. They may have been working DX split and forgot
about the offset. The worst case I've had, and this happened in
the last six months, was 10KHz!! I worked the guy split. Kinda
fun playing DX.
Another thing that I love and it bugs people. In the middle of
sending a CQ, if you have QSK (you can hear between the dits),
you hear someone tuneup on freq, stop. Send "?" and see what
happens. :-)
d. If after about a minute or so, you still don't have an answer,
move around. You may be on top of QSO that you don't hear but
everybody else does and moves on.
e. I start out at a good speed for me, about 35 to 40wpm. If the
answering station can go faster then we'll crank it up. If
the answering station is having trouble, then I'll slow it down.
If I don't get an anwer the first couple of times, then down 5wpm
to the next level. I'm sure someone listening to me to do this
is smiling or laughing. But it works and I don't care. :-)
Remember I'm racking up QSOs. The only exception is on 40 meters
during the day. If I'm in a crazy guy kinda mood, I'll start at
40wpm and go up in increments of 5wpm until 75wpm.
f. I never call CQ DX. It's just a thing with me. I'd be interested
in what the DX group on this mailing service think about other
stations calling CQ DX. Do you answer them? Is it easier for a
DX station (and we are all DX to someone) to answer a CQ or sit
on freq and call CQ? Inquiring minds want to know.
g. Always assumed in the above, you're using the right antenna 'cuz
a 10 meter antenna won't work too well on 40 meters. Keep the
SWR low, especially for QRP work. It's hard enough as it is.
And you all have stories to tell the grandkids about the time that....
These are just some of the things that I do. I find that sometimes
I just can't raise someone, so it's time to clean the shack, go read
a book or do 'honey do's (you know, Honey do this, Honey do that). :-)
I do other things than ham radio, really i do. The price of a divorce
will buy a lot of equipment. :-)
So what do you think? Hopefully this will generate some traffic
here.
Enjoy life and cul de k5fo dit dit

Into a dummy load of course.

I'm still using mostly a straight key. Although I can't imagine using it in the

for a straight key, or my wrist as well. :-) I have had good success using two
micro switches bolted together to make a set of poor man's paddles. The single
chip keyer chips sound exciting. Its probably about time I get serious and buy
one of the CMOS kits and update my sending skills. My current working keyer is

Ok, you've talked me into it.
I'm going to get out my old J-38 and get on the novice band with it.
I never developed any speed with a straight key. I used one for
a few QSO's a few years back, but I've been using keyers since.
Since my fist will sound like I'm QLF, I'll get in the novice band
and go slow.
I've just finished reading the book _Empire_Of_The_Air_ by Tom Lewis.
Darn good book. Anyway there's some pictures in the book of
David Sarnof using a straight key. I wonder what kind of fist he had.
I bet he didn't sound QLF.

Chuck mentions how we increase our QSO quotient using QRP. Good
suggestions, I use them all (however, I DO send CQ a little longer
than a 3 x 3 and I go SLOWER than Chuck does :-)
Another thing I really value is a choice of antennas. It really
makes the difference at times. Modest antennas OK, but having
two (or more) different orientations or polarizations can be helpful
and instructive about how the darned little things work their magic.
I personally have a cheap two position rad shack antenna switch to
switch in a double zepp for 40 and a 95 foot dipole....which brings
up another point: if you use several antennas that do not present
the 50 ohm match, you may need a couple of simple tuners ahead of
the switch. That is what I do. It is really fun to switch around
and sometimes makes the difference whether "to qso or not to qso"
at the qrp level.

I just got the most wonderful idea: recall I mentioned switching hands
when using a straight key to avoid fatigue? Well, why not run two rigs
at the same time - send CQ's on two different bands simultaneously!
(Chuck, can you carry on two QSOs at once?). God forbid that both CQ's
get answered; but you increase your chances of snagging someone and save
time to boot! I'll let you know how it works (after all, we've got two
ears and two hands - put 'em all to work at once).

As most know, W6SKQ, Bob Spidell passed away in June. I scanned in
the following written by Richard Fisher, KI6SN, as it appeared in the
Oct issue of the QRP ARCI Quarterly.
BOB SPIDELL, W6SKQ
1937-1993
One of QRP's best known and most highly resqted voices
fell silent in June with the sudden death of Bob Spidell,
W6SkQ. he was 56.
Bob, a past contributor to Worldradio, QRP QuarterLy, G-
QRP's SPRAT, and other QRP publications, for many years
had been one of QRP's greatest ambassadors. He held member-
ships in QRP organizations including QRP ARCI (No. 3135),
G-QRP (No. 355), VK CW Ops QRP Club (No. 67), Michigan
QRP Club (No. 177), NorthWest QRP Club (No. 20), and QRP
Club of New England (NR. 85), and is responsible for bringing
untold numbers of radio amateurs into the world of QRP.
A builder and avid operator, Bob will always be remembered
for his untiring advocacy of low-power operation. He was a
founding member of the Zuni Loop Mountain Expeditionary
Force, one of QRP's best known Field Day groups. Until his
death less than two weeks before Field Day 1993, the group had
operated under his call sign since its inception.
A friend to many QRPers across the country and around the
world, his hearty laugh, distinct fist, kind demeanor, wonderful
sense of humor and genuine willingness to help others into our
niche of Amateur Radio will be greatly missed. No radio operator
loved QRP more than Bob.

Just to claify my last (got some emails from some who were confused):
Two rigs, two keys, two hands, two ears. Since you're sending the same thing
with both hands (CQ CQ CQ DE ME) no problem sending with both hands at the
same time. Don't have two keys? I'll send you some of my spare paper clips
and thumb tacks! If you've got a wooden operating desk these paper clip
keys work great!
Am I a nut? No more so than Chuck! Remember, no need to buy any components -
you can make your own variable capacitors from tin cans, zip cord makes
great leadin (what's the impedence?), and no one will miss a few parts
from the TV.

Hold on there! This is where I take exception! I am right handed, and glad of
it, but once upon a time, I was talking to a fellow about sending with the
iambic keyer. He told me try reversing the leads and send leftie for one day,
and by the end of that day you won't want to switch back. Well In disbelief, I
took the square heathkit keyer, and turned it over, and tried with my left hand.
Well, later that day I had the soldering iron out switching the wires permanently! Funny thing is, my right hand is free to write in the log now.
I was a non beleiver till I tried! Now I have people come
to my shack in awe of this marvelous tallent, or at least they get upset
trying to send cq with my keyer %:-).

Subject: RE: Straight keys
Two personal comments from this thread:
Straight Keys - Although the top speed limit is lower, I really
enjoy a straight key. Guess it comes from wanting to simplify
things, particularly the number of wires. This is a "wireless"
hobby afterall.
Currently am using a Viking Key which was great when I first got it,
but seems to have worn out. Rather than a post that you make solid
contact with, the key handle pushes down a short rod that works a
contact in the base of the key. It has gotten pretty mushy of late.
Switching Hands - A few years ago, a left-handed friend who works a
keyer with his right hand said to me, "I know several left-handed
hams who key right and write left, but there are no right-handed
hams who key left and write right." Well, that was too much of a
challenge to take, so I started working the keyer left handed. Like
Brad, WB8YGG, I started out by switching the leads. Then I switched
them back and so now am proficient sending left handed with a
right-handed key. Thus I can use a right-handed hams key, and
vice-versa, without changing leads.
But, I also switched the mouse on my computer to the left side, but
try as I might, I couldn't get myself to work it with right handed settings.
Somehow the index finger needed to be mouse button 1. Go figure.
One problem with the left handed mouse is some games that insist
that MB1 moves a target to the left w/o provision for reversing this.
Cheers,
Mark

I send with a keyer using my right hand and a key using my left. Lefties have
all the fun (no wires to switch). I love the keyer and I use the keyer more
because I can write and key at the same time. Now with a third hand I could
type and send a the same time.

Hi,
well glad to see the group is once again awake and aware.
I love straight keys. I love to collect and use them. I like my hand
made solid brass key made in Canada and my Kent keys best. I also have
about 5 other J38 like keys. I use a straight key whenever possible, I
find it very soothing to my sole. I do have a few sets of paddles and
all types of keyers and use them also.

Ok,
As promised..just got it on the road and here is my views:
Please do not reprint this without permission (Yet).
If you are looking for something different in a QRP
transceiver kit S & S Engineering may have just the kit for
you. Their new ARK is a synthesized QRP single band
transceiver. It uses a super heterodyne receiver that covers
from 7.000 to 7.1999 MHz and the transmitter puts out 5
clean watts. The rig offers full break-in (QSK) keying.
What makes this rig different than the other QRP rigs out is
that it uses two phase-locked loops to synthesize the
frequencies. Tuning is done with thumb wheel push button
switches. When you are on a frequency you know exactly
what it is. If someone asks you to QSY up 5 you know you
will be exactly on that frequency. The rig also comes with
RIT, AGC for easier listening, crystal filters and an narrow
(200Hz) audio filter. There is plenty of audio to drive the
included speaker.
When I first looked at the $269.95 price tag I was a
little taken back. The finished transceiver has more features
than most (such as the narrow audio filter), but this is the
highest priced mono-band QRP transceiver that I am aware
of. As I finished building and testing the rig the reasons for
the price tag became more apparent.
S & S offers a guarantee that the rig will work as
advertised or you can send it back and they will fix it. They
have a company policy that they will do everything in their
power to get the rig fixed and out the door within 24 hours
of receiving it. If the problem is found to be caused by a
faulty part or fault of the companies it will be fixed for free.
If you have put a part in the wrong place or done something
wrong they will fix it for under $25.
I have built kits of all levels and all levels of
instructions. Some kit suppliers basically give you a bag of
parts and a schematic. Heath use to be on the other end of
the spectrum and tell you in minute step-by-step detail how
to assemble the rig. The S & S instruction manual is a
work of art. It was professionally written with excellent
quality type, good schematics and excellent photos. The
instructions are step-by-step, but not in the Heath approach.
One step will say put in all the resistors. There is a master
list of parts that has complete descriptions of each parts.
There is then a separate parts list with a two checkoff boxes
so that you can use this to build the boards with. The parts
list is in the back of the manual. At first I wasn't sure I liked
this approach. I went to the step that said to solder the
resistors and then went to the back of the manual to use the
parts check off list. While building the boards, I found this
worked fine. The parts list has complete descriptions of
each parts including things like the color code on the
resistors. This make part placement a lot surer. One of the
biggest problems builder experience is incorrectly
identifying parts and putting them in the wrong place on
the board. The assembly instructions for each of the boards
is separate and then the final assembly process and
alignment are each separate. The manual also has very nice
sections explaining the theory of operation of the rig and a
trouble shooting section. This was by far the most complete
and well done manual I have come across since building
my Heath HW9.
The next area I was really impressed by was the kit
itself. There are two main printed circuit boards and one
small board. There are over 1000 solder connections in all.
They clearly state that this is not a beginner's kit. I found
that with a little help a beginner should easily be able to
build this rig. It is in fact much easier to build than many of
the other QRP kits on the market. There are a lot more parts
in this kit, but the way the kit is packaged makes it a
different type of kit. The two main boards and their
corresponding parts are each packaged separately. Within
each board packaging parts are packaged separately. If
there are a lot of the same resistors or capacitor, they are
put in separate packages. If there is any chance of a part
being identified incorrectly it is in a separate wrap and
clearly labeled. The coils are all pre-wound. In one case
there are tiny surface mount capacitors and they give you
an extra in case you mess it up. It turned out that this was
the only part I had trouble with. I used some surgical
forceps that lock and managed to crunch one. It was no
problem, I just used a different tool and used the spare
capacitor.
My approach to building a kit is to take all the parts
out of the box and check them off and separate them. I
usually take a big piece of paper for the resistors and
capacitors. I label the number of the components (ex: R1,
C34), and put the leads through the paper. I find that when
I build I am much less likely to make a mistake using this
method. I also know ahead of time if I am missing a piece
and can call and get one sent before I need it. This is
usually my least favorite part of building the kit. I found
that the parts were so well prepared with the ARK 40 I
built that I didn't need to do this. I took a number of small
plastic bins and just dumped each of the pre-prepared
packages into each one. There were no missing parts with
this kit. With the resistors many had been sorted and I only
needed to sort out a small number of them. The same was
true for the capacitors. The S & S Engineering approach to
preparing their kits made the building process a lot more
enjoyable.
When examining the boards I found them to be clearly
silk screened and the best quality I have come across. A lot
of time went into numbering components so that they are
easier to locate on the printed circuit board while building.
The boards are double sided and plated through. This
makes the soldering a lot easier and solder connections
come out better with less chance of cold soldering joints.
The down side to this type of board is that if you put a part
in the wrong place it is a lot harder to remove it from the
board. The parts in the kit were also all top quality. The
case is fantastic and should stand up to about any type of
use.
This isn't a kit you would want to throughout together
quickly. Building is a type of therapy for me. After a tough
day of work I love to come home, lock myself in my ham
shack and work on building something. The nature of the
kit determines in many cases how much enjoyment I get out
of building. I found that due to the careful attention to
detail and quality of all components that this was one of the
most enjoyable projects I have ever done. I was able to
come home and work on the kit for 10 minutes or 2 hours
and enjoy every moment of it. I found that the manual was
complete enough so that I didn't get frustrated and was
written in a way so that it didn't insult my intelligence.
After you complete each board you are given some
simple resistance checks to perform with an ohmmeter.
You can tune this rig up without any special equipment by
using a receiver with a digital readout. If you have use of a
frequency counter, it is a lot easier. A scope is always
preferable for tuning up the transmitter, but you can do a
good job without one using a power meter capable of
reading QRP levels The alignment procedures are very
clear and detailed. They even give you a good plastic
alignment tool for the coils. If you run into problems with
the alignment the trouble shooting section should help
point you in the right direction to localize the problem. If
you need to take advantage of the service, you will find the
people at S & S Engineering knowledgeable and helpful .
I still get real nervous when I first power up a rig,
especially one that has so many parts in it. The more parts
the more likely I have made some dumb mistake. No matter
How careful I am, I always seem to put something in the
wrong place. I anxiously turn on the power while at the
same time looking and smelling for smoke. When I flipped
the switch on this rig, the power came on and no smoke
billowed out of the rig. Boy was I happy. I feel if I get this
far, nothing too bad can be wrong.
I started aligning the transceiver using my digital
frequency counter as directed by the instructions. I used a
small digital multimeter to check the voltage at one of the
ICs. The voltage was a little off. You change the voltage by
either spreading or compressing the coil windings of one of
the coils. It isn't very hard to do. I would suggest that after
the rig is completely operational and checked out you
might want to put a little glue on the windings to make sure
they stay in place. Most of the alignment procedures are
very typical of QRP transceivers. There are two coils and a
couple of variable caps to adjust the receiver section and
two transformers for the power output of the transmitter. I
didn't have a scope at home and used my QRP watt meter
to adjust for maximum output. The transmitter was putting
out better than 6 watts, so I adjusted it to about 4.5 watts. I
went to a hamfest the day after I aligned the rig and came
across a good deal on a scope. I went home and checked
the wave form of the transmitter out with the scope. I found
the wave to be very nicely shaped. I found that when I
played with the two transformers and adjusted the power
level down that the wave form was still very good. I believe
you can easily align the entire rig using another rig that has
a digital readout, a voltmeter and a power meter that reads
QRP levels.
Building the rig is half the fun. Putting a rig I just
have built always is an exciting experience for me. This
was no exception. I was impressed with the quality of parts
and had a really good time building the kit. I was very
anxious to see if the rig performed as good as it looks. I
usually find that I like to align a rig, put it on the air and
then take it apart and fine tune it. I usually go through this
procedure a few times before I am satisfied with the way a
rig operates. No matter what the frequency counter and
other test instruments tell me, I like to tune a rig till it feels
right for the way I operate.
I plugged in the antenna and key and turned on the
power. The 40 meter band was not in very good condition.
I tuned around a little and heard someone calling CQ. I
answered and he came back with a QRZ? This was a good
sign as far as I was concerned. I answered back with my
call twice and turned it over. Ralph,N3QF in Washington
DC, came right back to me. We had a nice forty minute rag
chew. The radio received an excellent signal report. The
other person was very impressed that my 4.5 watts was
getting through all the atmospheric noise. He said my
signal had a very nice sound to it. I listened on my
Kenwood 850 to the keying and it sure sounds sweet.
At first I had serious reservations about the use of
push buttons to tune around the band. I found that after a
few minutes I didn't mind this method at all. The rig
sounds great, is very sensitive, has great full break-in
keying, and is extremely rugged. The size is about right for
backpacking or portable operation. I am impressed with
this little rig. It is a fun to build and operate rig.

Subject: QSO Updates
Gang,
a few additions to the post yesterday on building up your qso rate
n+1) Take your receiver aperiodically (once in a while) and tune in
WWV on 10 or 5 MHz. I find that if WWV is weak on 10MHz, then
40 may be also dead. This happened last nite around 0245Z (UCT).
Later at 0330 or so the band came back like gangbusters. in fact,
i was up to 0700UCT working the band like crazy. worked a W7 for
an hour.
If we can get the digital guys off 14.100MHz, we could monitor
the beacons. This is an expensive network of systems around the
world. If you don't know about them, let the net know and I'll
let someone else write that up. :-)
n+2) When a QSO does start up, if you get a 559 or better, don't
repeat anything unless you are asked to. The way I do this is
I get a feel if the guy/girl is copying ok. If not, I'll either
repeat or slow down a notch. 90% of my qso's are at 25 to 20wpm.
That is where the majority of hams are.
Last nite I heard a guy call CQ CQ CQ ..... CQ (27 times) DE CALL CALL K
and nobody came back to him. I tuned up to 7.040 and heard one guy call
QRL? He waited, then CQ CQ CQ DE KB3ABH KB3ABH KB3ABH K and TWO guys
came back to him. If I had jumped in that would have made three. I'm
telling you, it works. Try it, you'll like it.
OK, I promise to go away for a week. I do post too much.
73 es cul de k5fo/qrp dit dit
I will be on around 0100UCT at 7.040 area. 0300Z at 7.110. Last
nite worked at 10 wpm for 20 minutes. Most difficult QSO of my life. :-)
But it was fun.........

Apparently there was a time during which people did that, and the FCC
frowned mightily on it; just "dit dit" lacks ID, and CQ is (to the FCC)
the correct "standin" for the other station's ID when there isn't another
station yet :-).
> Ok so "dit dit" may have some other meaning. How about just "CQ" for

Just one CQ means that someone tuning across the band has to tune across
your signal at exactly the right moment to realize that you're sending it;
a few seconds of CQ, however many repetitions that works out to at the
sending speed, works better. CQ CQ CQ DE WB7EEL WB7EEL gives some time
for people to hear the distinctive CQ pattern, and helps someone who didn't
get the call the first time write it down right; three by three offers a
nice balance (but gets a bit tedious if your call is long).

The problem is that the HF bands are not channelized. So, if your
CQ was short, the odds of someone happening to be listening to your
frequency is really small. More likely, hams are tuning around,
listening for a CQ. If you send it several times, the likelihood
of someone hearing it increases.
BTW, the VHF equivalent of CQ (kd6laa listening) is short because
it is channelized, so peoples may be listening on frequency.

Are there any QRPers out there in North Dakota who are willing to do a
sked with me? It is the last state that I need to complete 2-way QRP WAS
and I didn't hear any ND stations during the QRP ARCI contest. I had a
sked with Fred KE7X in Montana last night on 40 meters which polished off
the second last state I needed. He was using 2W out and was 10dB over S9
here at 0100Z so an ND station shouldn't be too difficult to hear on 40m,
but can also do 80m if necessary.

As you will notice from the title and the text, one of the reasons it has
taken me so long to complete the 2-way QRP WAS is that I am one really
confused lunatic. The text of the message is correct - I need ND. Ignore
the title!

Has anyone heard anything about the new MFJ 12W SSB rig? I was browsing
through the latest QST and saw their ad. ( They also talked about the
"improved" CW rigs, but neglected to provide any substantive information
about how they were better. :-)

Gang,
By popular demand here's the list of all 10M beacons - this list
came from HAM-server@GRAFex.sbay.org - like the ARRL email server,
this is also a gold mine of information.
As you scan this list it is interesting to note the power levels
of these stations, and the antennas used.
Okay, turn on 10 meters as you follow this list and let's see if
10 is really dead.

Yeah, does seem to be sort of "impure" doesn't it? I haven't done much HF
operating yet, much less QRP, but seems to me that everybody sounds alike
anymore. Can't tell one fist from another without a digital timer.

Randy was on 7.003Mhz last night around 10:30 PM EDST. He attracted a big
crowd. I was able to QSO him with my new homebrew QRP transceiver and a 68'
foot end feed wire antenna on about the 15th call. His signal was weak up
here in Massachusetts (S4 to 5). He was giving everyone a 599.
My transceiver is a highly modified version of the "Optimized QRP Transceiver
by W7EL"(Ref: QST August 1980, QRP Classics 2nd printing or recent ARRL
handbooks). The mods include a lot of filtering in front of the SBL-1 RF port,
wideband termination of it's IF port, an alot of stong audio filtering includ-
ing a 7th order ellipitical filter with 1.4:1 shape factor. As a result I was
always able to hear Randy through the pile up callers, tuner upers etc. Although
the receiver is a wonder of simplicity, most of the commerical radios I've
used would not have handled the situation nearly as well (would hear just a big
blur until the frequency quieted down), due to poor front ends, filtering and
agc.
It's true, if you can't hear them.....you can't work them.

Well, I felt in same way before switching to an electronic keyer.
I was thinking to do it since, although my fist has always been considered
quite regular, I could not reach very high speeds (not that now I'm doing
that much better :') . On the other hand leaving the straight key sounded
kind of turning the back to old traditions.
Then I decided to design and build the keyer electronic by myself (including
also a DVR all in one box) and that's it! With a homebrew keyer, my consciense
is now easy and, needless to say, from time to time I pull my old SK off the
drawer and use with the same pleasure as ever.

Reiterating -- mint condition, both appearance and operating, MFJ 9030
30 meter QRP rig --- purchased recently -- one of the new versions
(I guess that is what MFJ is talking about in their recent ads about
"improved" QRP rigs). RIT with center detent, increased audio output
and larger speaker, fused power input, and new type non-painted top
case cover. Price includes optional internal keyer. Orig box and manual.
Selling because it duplicates rigs and I need other toys.

Subject: More NICAD Packs
To: qrp@Think.COM
Well, I thought I got rid of all the NiCad battery packs. But, as I gathered
some stuff together for the Lawrenceville hamfest, I found a dozen or so that
I had tucked away in a special corner. So, if you need some, here's the deal.
These are military surplus NiCad packs, used.. There are 20 D-Cells in the
pack. They are set up as four 6-volt packs with some circuit that displays
the number of hours of charge left when you push a button on the panel. The
packs are in a metal case.. Obviously, this thing plugged into something
using the connector (weird type) on the back of the case. Size is slightly
smaller than a shoebox. Forgot the weight but it takes 6 or 7 bucks to UPS
them..
Tell you what I'm gonna do! For $15.00, I will ship you one. For $60.00, I
will ship you five of these beauties. I think that will cover my shipping
costs and add a few bucks to the 'New Rig Fund."
Anybody interested? Will consider trades......... What have you got?

It is a new magazine starting up that is supposed to focus on building
equipment. Sounded interesting. They have had small ads in some of the ham
magazines. I have misplaced their phone number, but someone might have it.

Let's see, I don't have the thing with me, but the transmitter and receiver
are both between 1 and 2 cubic centimeters in size, and they each have six
pins coming out from their bottom. I have a tech sheet that came with them
that tells me (I think) what each pin does, how much power to send to them,
etc... I've never worked with a digital circuit before, although I do know
something about them from my computer architecture class (although the class
was mainly assembly language programming and theory).
I keep trying to think about how I could use this in a project, but I
keep coming up with blanks. The biggest problem is that I only have one set
of the receiver/transmitter cubes, so any data I send is going on a one-way
ride... If I got another pair, I could try to wire a 50Mbaud cable for my
1200 baud packet setup :-)
So what can I do with this cable? Any ideas?

the "new" versions with the center detended RIT, improved audio
output, larger speaker, fused power input and very nice vinyl covered
sheet metal case top ( these are probably the "improvements" MFJ is
citing in their ads). Original box and manual.

Subject: New Ham Magazine
Cc: radio-info@ucsd.edu
The following is the text of a postcard I received last week. It
announced a new magazine that maybe of interest to the group. I
have posted this FYI and standard disclaimers apply.
Dear OM,
In the past, on at least one occasion, we have enjoyed
a QSO together (ed. I checked my logs and we QSOed in 1988 QRP).
I am writing to you because I want to tell you about a new ham
magazine which I am about to launch. It's designed especially
for the hams who like to build their own equipment and antennas,
whether from kits or "scratch-built", even modifications to
existing rigs. It's called Hambrew, and we are getting a great
response to the idea from hams all over the country! "It's just
what we need," I hear again and again.
I hope you will c'mon aboard and try a $20 yearly
subscription now. You'll like Hambrew - it's a quarterly by hams,
for hams, not sold in stores.
If you order before November 1, 1993, I'll throw in a free
bonus extra copy as a thank you for helping us get off the ground:
five issues for the price of four.
We've even go an "800" number to make ordereing easy for
Visa and MC holders: Call now and say "Hello"! 1-800-5-HAM RIG.
And thanks!
Warm Regards and 73,
George De Grazio, WF0K (ex KB0AHD, N0IHS)
I ordered the magazine and when I get my first issue I'll review it.

Subject: 40 Meters
Gang,
someone, Spence, mentioned looking for me on 40 the other nite at
0300Z. Well I've been there, it seems with the geomagnetic activity
the band is up and down. Everynite, at 0245Z or so until about 0330Z,
(Z means UTC for you newbies :-) ) the band dies and later comes back
like gangbusters.
I was in error last week, this saturday (tomorrow) I'll be at Texoma
meet. Look for either AF5U or K5FO/5 from there. We have a room set
up for a hospitality suite and will have antennas and rigs on many
bands. Whatever is open at the MUF, we should be there.
p.s. I'm taking signup sheets for the Northern California Club
and a page of notes on the other clubs. If you belong to a QRP
club and want it announced, send me email by midnite and I'll
take it with me. Purpose of your group, etc. or whatever is fine.
Short notes, etc.
Congrats to Doug Hendricks, KI6DS, on his QRPp Journal. It is the
largest QRP club newsletter in the world. Looks like it will keep
the rest of us on our toes. Reading it last nite again and note
that G-QRP club has about 5,000 active members.
I should not have talked about the warm summer. Winter is coming
in like a freight train tonite. Lows in the 30s and snow and sleet
predicted. Gonna have to fire up the fireplace. Makes me want to
get out the HW-16 for heat (kidding, just kidding).
I worked Ron, WB8RUQ, the other nite (28th) at 0222Z, ahead of the
0300Z schedule, and it was a good thing we did, 'cuz 0300Z was dead,
as mentioned above.

p.s. I do sign /qrp on the last callsign of my CQ's. Reason: most
guys/girls will respect it and they will most likely put in the

Well, I just got my straight key in the mail last night, actually. :-)
I've been practicing with it into a dummy load ( As I sit here reading
USENET news, I key what I'm reading... good practice. :-) I definately need to
develop a little more skill before I subject other people to my fist. ;-)
The funny thing is, as a new CW operator, I find that I can send slightly
faster with the straight key than with my paddles and keyer... I guess I
don't have to think quite as much about which paddle to press, and for
how long.

Speaking of buying/selling used radios....my 14 year old son and I just
bought an Icom IC-701 200 watt SSB/CW rig with IC-701PS power supply.
Of course it can do QRP, down to 2 watts, according to the previous
owner.
We are very interested in hearing from anyone who has had any kind
of experiences with this model of Icom radio, since this is our first.
We are not licensed yet; have nothing more than a long wire for
the receive antenna, but will become licensed HAMs soon. We've been
doing a good deal of listening at 7 MHz because it is so active.
1.8, 3.5, 14-15, 21, and 28 MHz are either very slow or non-existent.
Is this the norm? Also, we have been hearing some CW on both the
upper side band as well as lower side band in SSB mode. I need to
ask if this radio, the Icom IC-701 can broadcast CW in SSB mode?
Thanks for any answers, replies, etc. We hope to communicate with
some of you netters over the air waves in the near future!
Thanks again!

Grover,
That's the point, I didn't have to learn at all. It came as naturally as
sending right handed. That was what the ham had tried to tell me, but I
didn't believe him, till I tried myself. I have tried sending with the dits
on the index finger, and the dahs on the thumb, but there is a significant
learning curve there. 73 Brad WB8YGG

Subject: For Sale
1. Built and tested receiver PCB from "Better Ears for the MAVTI-40" see QST
article in October 1985 pg.14, or QRP Classics pg.140.
The receiver is built on a gold plated (2 sided) PCB about 5"W x 3 1/2"W.
It contains all the circuits of Fig. 6. The audio band pass has been opti-
mized for a 600Hz center frequency. Although a 40M double tuned band pass
filter is installed, this can easily be changed for the receiver to operate
on any band. The PCB also includes T/R keying and antenna change over. Just
add a VFO for a fully functional receiver. I recommend the NG1G premixed
VFO (see QRP Quarterly) since the VFO buffer to drive the SBL-1 is on the
PCB and this would allow you to build for any band. Add a transmitter and
sidetone and you can build a complete transceiver around this module. One
notable feature of this reciver circuit is the notch filter which works
quite well. Price does not include the few components that are chassis
mounted (e.g. jacks, pots etc.). Full documentaion included. Price $50.00
2. Set of (3) PCB's for the "Ugly Weekender II" see QST June 1992 and 1992
ARRL Handbook. Price is $10 with documentation.
Or, I will furnish a complete parts kit for this transceiver with these
boards (less 7Mhz calibration osc., enclosure, knobs and jacks) for $50.
Shipping is not included in any of the above prices.

It was a cold dark weekend in Tennessee. Halloween was fast approaching.
The moon was full. The deamons, witches, goblens and ghools were all at
maximum strength. The forces of nature were exerting their own power.
It was cold. Oh so cold. Not your normal everyday cold, but a wet cold
that has a way of getting down to your very bones. There is no way to
warm with such a cold. Sweaters, heat, fires all are of no help.
I started to pace. I had an eeeeerrrryyyyy feeling. Not being
superstitous, it was hard to attribute it to Halloween. But something
was amiss. I had my father-in-law over for the weekend and had a stack
of work that needed doing. Fortunately or unfortunately the work all
involved outdoor tasks that were rendered undoable by the current
weather conditions.
I didn't feel like starting on any new building projects, but somehow
had managed to wander into the ham shack and found myself seated by the
work table. Well there was one small project I was interested in
finishing.
"No, don't do it," I told myself.
Next thing I knew the soldering iron was plugged in and I was sticking
pieces on the CMOS Superkeyer II board. I finished sometime later and
attached the battery holders and jacks. I put in the batteries and
actually expected this to work the first time. There are very few parts
and I was careful putting them in. I checked the bottom of the board
very carefully with a magnifying glass and things looked perfect. Only
problem was .. it doesn't work. When I was putting it together there is
a 3 hole position for sometype of crystal device that is labeled Z1 in
one part of the article and I think Y1 on the schematic. It said
something about a digikey part that is 2mhz. There was a blue 2 legged
part that had a 2.00000 on it. I looked at the schematic and the middle
was ground.. stuck this gizmo in where the 3 legged part should go and
ignored the middle ground position. Anyone know anything abou this? How
about it Chuck, you ever finish the keyer. maybe it wasn't such a
bargain for $25 after all. There was also the 102 cap missing. stuck
another in its place. Any suggestions?
Well, boy was I depressed now. I checked the keyer, but wasn't much in
the mood to mess with it. So I decided to take apart the ARK 40 and
retune it. I do this quite often. I put a kit together, align it
carefully and get it so it works. I then get on the air and test it for
a while. Sometimes even though the measurements were correct, the rig
doesn't feel right. The receiver was working well, and I was getting
great signal reports, but still I wasn't satisfied. I re-aligned the
receiver and BFO and put it back together. The 40 meter band was
horrible, a lot of broadcast stations. My Gary Breed 40 meter which
usually works well, was totally worthless. I fired up the ARK. The
stations were coming in crystal clear with the audio filter off. I tuned
in a few signals that had broadcast signals almost wiping them out. I
flipped on the audio filter and it about elimintated the problem. Next I
turned on the 850 and started to compare weak signals and signals that
had a bunch of inteference. I would really like to hear from other
people using this rig and get their impressions. So far I am more
impressed with this little rig than any other I have built (probably
should be for the price). I talked with a professor here at the
University and we may bring it into the communications lab and run some
measurements on it. I am really anxious to see how my impressions come
up against real live accurate measurements. I would guess that the
sensitivity of the receiver will measure fairly well.
Sorry if I have bored anyone, work was crazy and had to write.
Have a good one.

Hi CW fans,
Yes it's a nice idea to send CW with the hand that you don't use
for writing. (especially for contest operation).
I practice it, too.
BUT: Can YOU really write something down whle ur sending code???
I CAN'T.... (is sumthing wrong with me? I cannot even speak
while I'm keying....)
Maybe I'm still a newcomer, even after 12 yrs of CW hamming...

Well, I hate to admit it, but no, I don't actually write with my right hand
while sending, unless I'm going 10wpm or so. The main advantage I see is that
the pencil is already in hand, and that the paper and keyer are physically
separated so that they don't get in each others way. I find this a big advantage
when I'm putting a new home brew rig on the air with wires every where. I also
have a hard time talking while sending, but I can perfectly understand my xyl
while she is standing there talking, but I never reply. Maybe that's why there are so many divorces amongst the ham population?

Doug, and I quote, says " Say, Monday was a dead day on the net.
What happened, you guys have a rough weekend??? Where is Chuck
Adams????? CuL, 72, Doug". Ha, and you thought I wasn't serious
when I said I was cutting back. :-) I'm in overload.
Texoma last Saturday was cold and there was snow on the ground.
Friday nite starting about 10pm there was sleet and snow at the
ranch. I thought that I might not be able to drive to Texoma at
6 am on Saturday, but I awoke to a 26 degree temperature, but no
accumulation of frozen stuff of any kind. Drove up with NN1G-40
in the truck, listening to the CQ WW DX test in full swing, but
did listen to CW most of the way with no problems. Did not operate,
since there is no way I'm going to subject anyone to a 950mW signal
mobile. :-)
The OKlahoma QRP group was there, about 10 of them anyway, and Dave
AF5U and I set up some rigs in a suite in the hotel. We had quite
a bit of traffic through the room all day. Antenna situation was
poor, but we really didn't have time to operate anyway. There are
a large number of QRPers out there that don't belong to any organization.
They are quite happy to just do their thing and happy to show up once
in a while during a QSO party, field day, or whatever. Some never get
on the air. That's what it is all about. Not everybody has to belong
any organization. That's life.
OK, now to the topic at hand. Dave, NN1G, has come out with the new
version of the NN1G rig. It's called the NN1G Mark II. It will be
published in the December issue of the QRP ARCI Quarterly. It is set
up for either 80, 40, or 30 meters and of course, the 20 meter version.
The board for the receiver, which I now have one of, is now 2x4", slightly
larger than the previous rig (which I guess is called the Mark I). I
got 4 or 5 pages (didn't count them last nite) on the new rig and what
I'd guess is a copy of the article. He went to the 10mm 10.7MHz IF cans.
These will be cheaper and take up a little more room than the 7mm IF cans.
Guess there are too many new hams that have not enough experience to remove
the small cap in the base without doing some damage. The 80/30 meter versions
do not require you to remove the caps. I don't have the info with me, but
the IF freqs changed for 10.0MHz on all the bands (guessing on 20M, since
the article did not include a table for the 20M band, but the old values
should work).
The new board is beautiful and without silk screening. Made by FAR
Circuits. Also drilled with new mounting holes (hope this was my
suggestion that they took). Note said that Dan's Small Parts will
have the new boards. I'll call and check and get back to you.
I got a new set of crystals for the NorCal40, but haven't tried
them out yet. The US Post Office, in it's infinite wisdom manages
to bend one of the cans, so I have to check out all the crystals
before putting them into the rig. I built a prototype oscillator,
and was checking 100 crystals on 4.9152MHz, 50 each from two different
manufacturers. Experiment to show activity and resonant frequency and
distribution of a batch of crystals. I used to do this stuff in my
undergraduate days for HP, James Knight, and Collins Radio. Look at
the name on the patent for the digital thermometer for HP. I digress....
Someone check on FAR catalog, as I can't find mine right now, does
Fred have a board for the Doug DeMaw F,R, and Q circuit from "QRP
Classics" book? I need to build one up or borrow one. My fax number
is (214) 788-1376, if you have a catalog.
I also now have a scanner. If you have something, not copyrighted,
in print that you think we should post to the QRP email group, let
me know. I ain't proud. :-) I can post catalogs from FAR and
Dan's Small Parts, which I don't think is commercial use of this
group, but distribution of information that we all could use. Depends
upon how many of you guys and girls are paying for the line. I know
that Doug H. spends some money on his email for long distance calls,
but he doesn't seem to mind and he is hungry for information.
Education is expensive anyway you get it.
OK, back to my hole. See you in a few days.

Subject: Left Handed CW
I learned early in life (and I am right handed) to send with the right
hand and with the pen in my right hand at the same time. Then the transition
from sending to receiving requires no additional work on my part.
I know I take a lot of flak over my code speed. I don't force anyone
to go at any speed but that which they are capable of. At speeds less
that 40wpm, which is 99% of the time and 85% of that is below 30wpm,
I write down every word. Sorry, it's just a habit that I have. Reason,
to keep in shape and later, when I'm filling out a QSL card, I can
remember what the individual said, rig, wx, etc. and make a note on
something that I thought was neat. I can copy at any speed in my head
and not write down a word. It's just that I have written so long that
I don't want to give it up.
During a contest, you can send, copy the exchange and back to the
ending and start the next contact. I personally wonder about keyboard
operation during a test, where one is using CT or whatever, then sending
with a key. Yes, I know about using an interface, but you're talking to
the wrong person to even think about doing that. I am somewhat of a
purist. Wouldn't think of having a computer do everything. :-)
I can outdo any computer that I've ever seen on copying through QRM,
but I don't want to think of a computer ever winning SS, CQ WW DX CW,
or any other major test by doing everything. I imagine the big guns
all have computers, at least that's what I see on the cover of CQ
whenever they show one of the big winners. It doesn't seem fair to
just type in a call, push one button and have the entire exchange done
for you. What's the fun in that? I have never won a contest on the air
and never will. Not important to me. But I do respect those who do,
I know how much work it really is.
The Dinasour Valley DX Society took seventh in 1-A in Field Day.
I'm not on my soapbox here gang, just started out with pen in hand
and sending at the same time. :-)

Subject: NorCal 40
Thanks to all of you who have ordered NorCal 40's, and not gotten them yet,
for your patience. The second batch of kits are on their way and you
should get them within a week or two.
Note to NorCal 40 builders: The errata sheet that comes with the kit
describes how to choose the right value for resistor R6, which sets the AGC
level. As it turns out, R6 may have to be larger than 10M in some cases.
An easy trick is to use the 10M and 4.7M resistors in series. You'll know
you have the right value for R6 when it doesn't reduce the receiver volume
under no-signal conditions. However, you should be able to hear the AGC
reducing the volume of loud signals.
As a final tweak, if you used an 8.2M or larger value for R6, you might
want to decrease the size of the AGC capacitor, C29, to 1.0uF. You must
use a non-polarized capacitor, since this point of the circuit can have
either a positive or negative voltage.
Those who haven't started building their NorCal 40's yet will be happy to
know that only two of the first 20 or so builders encountered any
difficulty. A side effect of this is that I have NOT gotten deluged with
phone calls or letters. So, with this newfound courage, I hereby offer my
home phone number, (415) 592-2700. Feel free to call me if you have any
difficulty building the kit. (Before you call, make sure you have gone
through all of the steps in the Troubleshooting section of the manual,
please! Imagine your embarassment should we discover that you have nothing
more serious than a solder splash!)

Chuck, why don't you scan the new NN1G-II artwork, mirror image it, and put it
on think.com under the artwork directory, that is if NN1G hasn't copyrighted
it. That way we people that don't have the means to buy the latest kits
very often might be able to build the board, and scrounge the parts..

I'm new to this group. I have been considering QRPing for awhile now, and I'd
like to find out what are the chances that I can do it. Here's my
question: Has anybody in QRP-land been working QRP with an indoor antenna?
(You guessed it! Apartment-dweller with antenna restrictions!) Is this
meaningful, i.e., should I even bother? If it matters, for now I am
restricted to Tech+ bands and 10wpm code, but that will change soon... I hope.

Finally got to do it!
Ever sence I got my ticket , I wanted to build and get at least one contact
on a Transmitter that I think was designed in the 20's....a single triode
filament type # 26. ( 1.5 v 1.05 amp fil. other wise like #30 tube)
The tube being available at Antique Electronic Supply, along with socket,
tuning condenser, and other assorted parts, all I had to do was wind the coil
and cut up a wood base to mount it all on.
B+ is 100v and oscillating, the tube draws 10-12 ma.
Plate coil is 40 uh, tuned by a small 50 uuf condenser.
Ant coupling link is 6:1 turns ratio, inter wound with the 40 uh
( if interested, I'll send diagram and physical layout plans right here,
which are compatible with text screens...all ASCII )
Any way... I had built it 4 months ago and all that remained was to get the
FT 243 crystals in the mail.
So for too long a time, it just sat at a friends house, as a decoration.
Two days ago, the crystals arrived.
I called N1KGY on 80 m CW all afternoon to tell him about it, sence the
rig was at his house (he is a beginner in all this so it's a big thing to
him).
Yesterday evening, he came over and we went to his place...only to find we
forgot the 5 ohm 10 watt resistor to drop 6vdc down to 1.5 vdc (aprox!)
to run the filament with.
Radio Shack was closed, and his wife did not think too much of us wanting
to borrow some toaster wire out of her 2 slice pop-up toaster.
RATS!
But... we had an 811A ( 6v 4 amps fil, and easy to sub for 26 )
which, if run at 100v B+, should act similar to a #26..
So, 'lets try it!'
To connect to the plate, normally pin 2 on #26, had to run a wire by
shoving tube ( 811) pin down on it in pin 2's position, and run it up
to the top of the 811 .
There, it was simply twisted around the connector.
Everything else was able to stay as it was.
Connecting up the power supply with 4 wires...A+ A- B+ B- , and
turning it on, the tube lit right up, and the 6 volt 3 amp supply hummed.
(Wooo we better get this done soon!)
Plugged in a crystal for 3710kc, and set the 50 uuf to full mesh, the set
was tap-keyed until the right setting on the 50uuf was found.
It works! It's ALIVE! and almost no chirp, either!!!
Off comes the 51 ohm 1/2 watt resistor load, and on goes the antenna.
The receiver, went to a second wire indoors which we draped around the
living room ( while his wife scowled at us).
Myself, having run QRP before, and at much lower levels ( gave my self
quite a jolt contacting someone on 35 mw) , I had Chuck (N1KGY) sit down
at the key, and go thru the tune up oddness such a rig has, and so be the
one who catches someone.
Chucks ant is not all that swift, being a 40 mtr center fed with 300ohm
twin lead...put up for SWLing mainly...and never got around to changing
it over...
So we used it as a random wire single worked against ground....which
'works' for our intercom-like use over the 20 mile distance between us.
( We use 80 CW for that and run 10-25 watts for such QSO's de la information)
Being rock bound, we had to sit and wait for someone to do a CQ or finish up
a QSO close by to our freq, before we'd call them back...so we waited.
1 kc above us, was a guy calling CQ and not getting replys...so we tried
to reply...tried and tried and tried....so same the gyy out there, calling
CQ....calling CQ...calling CQ.
"Come on man! hunt around the dial! we're just below ya! we're here!
we're here!", I said aloud, to the 811 ( so it appeared as ).
( Chucks wife frowns at us , while she ducks under the Rx ant going
across the kitchen and into the living room)
Well, we never did GET anyone on it, but using a similar rated set and ant,
I once got 2 stations...so it's only a matter of time....
I went home, the rig stayed there, and it's evening now, and I k n o w
that Chuck will give it another try...and will get some one!
And...I get to hear the rig! Thats the best part!!!
I gotta go listen! See ya later!

Dimensions simply cut to suit stock and parts sizes...plywood,sanded &
varnished.
Tube socket, a 4 pin 'standard' , flange type, was mounted
by using long threaded #6-32 rod and 4 nuts each.
Crystal socket ( Also at W 0 L P S ) was mtd using #14 wire, L shaped.
Rod was obtained at 'Home Depot' hardware store.
Coil form is white PVC pipe, sanded with #250 grit to give it 'grip'
for the #24 wire...then wire is varnished to lock the turns.
Looks like ceramic when done.
(If anyone wants the coil winding formulas, contact me)
Wiring was done with 'routed' #14 ga. bare solid.

Gang,
anyone worked 17 & 24 Mtrs on any of the contests?
reason for question: i'm redoing the QRP ARCI Contest Forms and the
question came up about these two bands. Field Day is allowed on them.
Seems like I read some time ago that 30M was the only band not allowed
for contesting. Am I dreaming?
What are your feelings? Can you do the above bands QRP and with HB
equipment?

Follow up on #26 Triode oscillator-transmitter with 811 sub.
This occured tonite...the nite after N1KGY and I tried out the rig at his
place and so far did not catch anyone.
Keep in mind, now this is an open-to-view , very simple-minimum parts rig.
Only 8 parts and you can see em all...doesn't look like it can do anything.
Well, as he and I use 80M as our intercom..(rather than go thru all the
malarkey one gets on 2 mtrs)..I was dialing around with the receiver while
keeping watch on our adopted call freq with the Transceiver.
I tuned around thru 3710 kc, and heard a flurry of stations at about 3711
along with a teletype stations churring away.
I'm using the wide filter, so can hear over a 2kc region and Boy! it's busy
out there.
Then, a hair below 3710, I hear a faint peep peep behind the other stations
and so I switch to the narrow filter and dial in on the signal.
I picked up:
K ~~ NW ~~1UN~ de ~* GY N*~- Y *~@ GY K
Now...you tell me what I was thinking!
You never saw any one twiddle their knobs and dials so fast...
Knowing how he is set up, and how awful his reception can be (always 2.5kc wide
full time), I set my self where I know he'd be listening to him self, yet
not where the other stations would drown me out .
So, I reply:
N1KGY N1KGY de KA1UNW KA1UNW K
I had to nudge the Rx a hair up, cause someone with a very wobbly old
vfo'd set is chirping into us...but..way way way in back there....
almost all covered over.... :
K*~ NW d~ * KGY * @ ~ .! *
My golly! That WAS him!!! Thats the #26 with an 811 sub!
Not sure if or not he was still sending, and because the air was quite full
enough already, and who knows who else is running QRP there...me and my
25 watts would just make it all worse...
....I was getting ready to move him up to our usual freq where it's a hair
quieter and we'd both run 15-25 watts...and not run over those on 3710.
Figuring to call him, and tell him to QSY up to our freq..and him knowing it
was NOT one of the Xtal freqs, he'd have to use his Big rig....etc
Well, before I could do that, he calls me on the telephone and nearly
burns my ear off:
'YOU HEARD ME!!!? YOU HEARD ME!!!?'
"yes! and I hear you now, too...."
(muffled sound as he covers phone) He heard that oscillator we were working on
-clatter noises- (his wife on phone now) 'You actually heard Chuck on that
plank with the wires all over it?'
"Yes..I did----"
'Oh my gawd! so THATS what thats for!'
(now Chuck regains use of the telephone)
'I don't beleive it! I can't even measure the output it's gotta be so low'
"Well...once a signal gets on there---"
'There's so much noise and other stations--- (huh? oh, yes...you can get
near it...just don't touch the top part) --She wants to look at it...
How were you able to hear me----(clatter thump) ---
(his wife in back ground:
'gee I didn't know it lit up like that..looks better than it did before')
----well the rest was a lot of confusion...but we plan to re-do the test
at a more suitable time---less QRM....and also explore 40Mtrs...
He's been there already, sence he also has, along with 3710, 3700, 3686,
the 7110kc xtal, and he found that the 80M coil and 50uuf cap, will
JUST reach 40mtrs....so.....
As near as I can guess...because, all measurements were done using the #26
and a variable dc supply to run the 1.5 volt Filament, I have no idea
what really, an 811 will do on 100vdc.... maybe 1/4 watt...
When we plugged in the 811, I didn't bring my VOM and Chuck has, at best
a couple of non working flash lites for testers!
Those won't light up with the kind of power we were using.
So, going by how much the B+ transformer warmed up I can estimate only, that
it's not much over 1/2 watt, best case...more likly 1/4 watt.
Sence He and I are NOT at all Line Of Sight to each other...our RF path
has to be via the sky wave.....( 10mtr tests confirmed no LOS for us)
So...that means then the signal had to make it all the way up and back from
the E or F layer...what? 120 miles...so 240 mi round trip?
Thats a long ways for a quarter watt to go and still be noticable!
Boy..what must it have been like during early radio....

transceiver.. need the room and have too many rigs. I built it for an
article and tested it pretty thoroughly.. not used other than that. It
is tuned down to about 5 watts, but seems to easily put out a nice 8
watts. The tx signal has gotten excellent reports and the receiver works
great. There are 2 small places on the top that are small areas where
the black paint didn't get painted (telling this because some people
only want rigs that have absolutely no marks on them). This is a good
backpacking rig, I have been using it powered off a small gell cell
(never been out of the shack).
The completed transceiver measures 6 inches wide X 7.25 inches Deep X
3 inches high. It is small and rugged enough for backpacking. The rig
can be tuned to cover any 50 khz of the band the kit is built for
(advertised value-believe it is more like 48.?). The
transceiver can run off a small 12V gell cell and will put out
5 watts (7-8 easily) from a +13.8 v source
The rig has Semi-QSK transmitt/receive switching. There is an
audio derived AGC circuit and two stages of audio filtering.
$165 postage paid in US (kit cost plus postage.. no assembly or
alignment charge).

Hi George (N2OWO) as well as everyone else,
I,m new to the group also, (Oh boy two Newbeeeesss). First it's not a
dumb question, I have the same basic problem.
George look at the Jult 93 QST page 34, there is an artical titled Honey
I Shrunk the Antenna, this might be of some help. Also there is another
artical in the November issue on compact loops.
An aquaitance is attempting to put together a Ham Stick dipole, this
might be something to look at.
In my case I am home brewing a 30 Mtr rig and I want to take on the road
with me. My job requires that I spend a lot of time in Hotels. (I'm an
Airline pilot, when not radio active). Im looking for anyone with
experience with an antenna that is compact, easly carried in a suitcase,
reasonably efficent, and could be set up in a hotel room, that is
sutable for 30 Mtr QRP.
Someone must have had to deal with this problem in the past. Any
Ideas ?

Hello All -
I have two queries for the group:
1. Am I the only one who was missing pages 5, 6, 35, 36
from the October 1993 issue of the QRP Quarterly?
2. Does anyone out there have a copy of the "super tee"
tuner? I believe it was featured in a previous issue
of QQ, but that was before I became a member.
Any assistance in getting a copy of this article will be
appreciated.
Thanks.

Hi Scott (and the net):
Having following Argo prices quite faithfully for a year or more now, I
can say that the 505 will sell from $125-$200 and the 509 goes from
$190-$240 and the 515 is out of sight at $300-$400. These
all depend on accessories and condition. For comparision, Ten Tec
sells the Argos reconditioned for:
505: not listed anymore (last listing was about $175 I believe)
509: $275
515: $395.
Yikes.

Hello All,
Well, I for one am hooked on the idea of hollow state qrp. I'll probably
use a 12AV6 since I have a number of them lying around (I have to admit an
811 *is* more impressive). To Randy, KA1UNW, I pose the following question.
Can you fill us in on the actual number of turns in the coil (pri/sec)? It
would save this EE from plunging his dusty Handbook.

Subject: artwork for nn1g-II/norcal 40
well, here I go again, I'm not sure exactly why, but here I go again...
For us semi purists out here in T.V. land, can the artworks be made
available for the nn1g and the norcal-40, or is this something that is
copy written, or is it just that I need to go soak my head.
I would like to share in the wealth of the talented individuals that have
designed these rigs, but don't typically have the $75, or even $50
in one place at any particular time. Therefore, it behooves me to generate
a circuit board by copying the original artwork, if legal, and then gather
parts over time. (I know what you are thinking, the cost may actually be
more), but remember that I have this problem, with getting the $ in one place.
Also , a lot of my parts I buy/scrouge at cheap prices if not = 0.00. Thus
my cheap hobby perpetuates.
So what say folks? how about it can we scan these artowrks or not?
If so I would also like to put them on the anon ftp site for others
to use as well.
Please note, that I won't run out of projects if the answer is no,
But it would be fun to experience the same things everyone else is on the
net.
P.S. NO I would not make p.c. boards for resale in case anybody wonders...
my p.c. boards don't look anything like the professional ones FAR produces, and
are only funcionally equivalent. I only make boards for me, and that's that.

#26 Triode Transmitter...coil info
( note..several were tried and they all worked about equally well, one was
an attempt to allow 80/40mtr on one coil ,so I'll give both)
80 mtr only 9-50 uuf tune cap as C1 in the #26 diagram
Using white PVC pipe labled as ' 1/2" pvc 1120 sch 40 astm-d-1785 '
..whose OD is 13/16"....( aka 3/4") Cut to be 3" long, and sanded to remove
the shine...(makes easier to wind wire and lock with varnish)
4 holes drilled to fish wires thru where start and finish of coils are to be
and 4 more 90 deg apart on bottom to fish wires back out to ckt.
Holes were made using a PC board drill.
#28 wire was used for pri and insulated #24 hook-up wire for sec.
Finished coils looked a lot like ceramic ( bonus for looks!)
46 uh ....62 turns 1" long pri
10 turns sec...wound ON lower part of pri.
note...80 mtrs will occur close to 2/3 mesh on C1
------
6:1 turn ratio's seem to work best
80/40
Same pipe as above... same cap.
37 uh ... 55 turns 1" long pri
9 turns sec... as above
note...80 mtrs will occur at almost full mesh...while 40 mtrs will
occur close to wide open mesh.
-----
Quick coil formulas -- do on calculator ( leave the dust on the books)
turns = sqr ( 83 * uh ) using that pipe, 1" long coil
turns = sqr ( 400 * uh ) using Papermate pen barrel, 1/2" long coil.
actual formula ( inches )
D= diameter of coil form
B= length of coil it self ( you select, but usually best if 1.5 - 2 D)
A= D/2
Turns = sqr( ( uh * ((9*A) + (10*B)) ) / ( A*A ))
----
Quick formula to find uh
C= uuf of tune cap at 2/3 mesh (aprox) --- I used 37-40 uuf *
F= freq in mc ( mhz )
uh = 25330/(( F*F)* uuf)
* Usually, o.5 to 1 uuf per meter ( 80 mtrs: 40-80 uuf) is a good value
to use for most HF work below 11 mc.

Wow! I think it's wonderful that some folks on here are considering
tube + QRP rigs. I'll have to dust off my 1972 ed. of The Handbook
and see what my collection of tubes can do (that's the only edition I
own; I've requested our library purchase the latest edition but their
budget is shrinking).
The only problem working with tubes is the necessary power supply - not
too convenient for portable operation...

I have in my hands a letter that I received last month dated 10/13/93.
This letter is from George De Grazio, WF0K, and I quote:
"Just a quick personal note to thank you for your subscription order.
Our first issue if just today off the presses and is being bound, trimmed
and made ready for distribution to our subscribers. You should receive
your copy within the next two weeks."
Well, I haven't heard a word. Anyone else out here received similar
letter(s) and has anyone received a copy.
See you on this weekend for the most famous contest of them all, SS.
My goal. To do all 70+ sections with 0.95W with whatever combination
on 40 and 20 meters. Using only the NN1G rigs. We'll see if the
front ends can handle the loading and if the rig has the selectivity
required for this monster of a contest. Read QST, there are some
slow freqs set aside. I'll be down as low as I can go and not get
outta the band. The bands will probably look like a Gaussian distribution
with the major pileups near 30-40KHz from the low end.
See you in another week. Next week will be like this one.
