My $.02 on the nail issue:  Nails aren't made to 'exacting' specifications
and the material certainly is homogenious.  I know the value of good
core material first hand.  In the late 70's I bought one of the first
Ten-Tec Triton IV's with permeability tuning.  They managed to get
a 'sour' run coils that went into those vfo's.  That thing would move
around the band faster than a cat on speed.  The great folks at
Ten-Tec quickly caught the problem and replaced those vfo's, but it
made a lasting impression on me about the quality of core material.  For
a quick 'lemme see what would happen' it might be ok, but don't put that
on our ham bands.

Toroids, part 2 of 2--

Next, I did some experiments this week to look at the effect of
varying wire size vs. removing turns or compressing/spreading turns.

I dug out the T68-2 core with 16 notches and wound it with 16 turns
of #18 wire, the largest size that would fit on it.  I resonated it
at 7.9 MHz on the Boonton 260A, which took 278.0 pF, corresponding to
an inductance of 1.459 uH.  I removed the wire and rewound it with
#32; this resonated with 269.3 pF, 1.507 uH, an increase of about
3.3%.  (The Q with #18 was 222, while #32 only had a Q of 138, which
is to be expected.)  I used these two sizes to maximize the
difference; my original experiments used every even numbered size
from 18 to 28.

Next, I took a fresh, unnotched T68-2.  I put 16 turns of #18 on it,
spread out to leave a 30 degree gap between the ends.  This resonated
with 254.3 pF, for 1.596 uH.  I removed one turn, to 15, without
disturbing the spacing of the turns.  It resonated at 280.2 pF, 1.448
uH; going from 15 to 16 turns showed an increase of 10.2%, or a 9.3%
decrease if you go the other way.  That is quite a bit larger than
the 3.3% increase obtained by simply rewinding with considerably
smaller wire (with corresponding drop in Q).

Next, I replaced the turn--back to 16--and compressed the turns to
leave a 180 degree gap.  This resonated with 200.5 pF, for 2.024 uH
or a 27% increase over the 30 degree gap.  Finally, I compressed the
turns as much as possible, leaving a gap of about 260 degrees.  It
now resonated with 177.4 pF, or 2.287 uH.  Going from a gap of 30 to
260 degrees resulted in an increase of 43%.  Agreed, this is a pretty
radical compression, in light of the rule of thumb of winding toroids
with a 30 degree gap, but it does give a good illustration of the
magnitude of inductance changes possible by simply varying turn
spacing.

Recap:

Core 1:  T68-2, notched to insure uniform turn spacing from coil to
coil.  Test frequency = 7.9 MHz.
   16T #18 = 1.459 uH
   16T #32 = 1.507 uH

Core 2:  Different T68-2 (not notched); 7.9 MHz.
   15T, no compression, 1.448 uH
   16T, 30 degree gap, 1.596 uH
   16T, 180 degree gap, 2.024 uH
   16T, 260 degree gap, 2.287 uH

(And what would that compression from a 30 to 260 degree gap do to a
tuned circuit?  It takes about 324 pF to resonate 1.596 uH at 7 MHz.
With 2.287 uH instead, the resonant frequency would drop to below 5.9
MHz.)

Of course, winding wire on a T68-2 core makes it a bit difficult to
control the spacing with extreme precision, even with the
notches--while each turn is always the same distance from its
neighbors where it passes the notch, the remaining 90% of each turn
could vary by a few thousandths of an inch from coil to coil.  How
about a coil form where the entire length of each turn is rigidly
controlled?  Easy--wind it on a screw!  While this results in a
solenoidal rather than toroidal inductor, it would still show the
effects of changing wire size.

Using a screw has its own problems--the metal would not be an
appropriate core at the frequency of test [see my earlier message on
using nails!], and the relatively small size of a screw would result
in a coil of low inductance and increase the effects of parasitic
capacitance and inductance in the test setup.  The answer was to use
a large, nonmetallic threaded rod.  During my lunch hour at work I
put a scrap piece of 1" diameter teflon rod on the lathe in the
machine shop and threaded it at 16 threads per inch.

I screwed solder lugs onto each end, and soldered on 4" leads of
stiff #10 wire.  I calculated the inductance of the leads from data
in the ARRL handbook and subtracted it from the results.  (What's the
permeability of teflon?  Probably quite close to 1, which I would
expect, since measured inductances agreed closely with the calculated
value.)

With 40 turns of #32 wire, I resonated the coil at 2.500 MHz with
309.3 pF.  After subtracting the inductance of the #10 leads, the
measurement was 12.928 uH, Q = 79.  Rewinding the rod with #18 wire I
got a net inductance of 13.013, Q = 204.  Interestingly, going to the
smaller wire resulted in slightly lower inductance, while a slight
increase was seen with the toroids.  However, the change on the rod
was even smaller--0.6% vs 2 to 3% on the toroids.  Naturally, the Q
was higher with the larger diameter wire.

Why did a smaller diameter give a slightly higher apparent inductance
on the toroids but slightly lower on the solenoidal core?  I'll leave
that one to the engineers and physicists, but once again the point is
that dramatic changes in wire size (with all other factors remaining
constant) have generally insignificant impact on the net inductance
of a coil.

    I'll counter his bet with my own, based on actual experiments:
For most of the toroidal coils that we typically use at HF, I'll bet
you will NOT need to reduce the turn count by one or two due to
increased distributed capacitance.  It does increase, but I contend
that it's not enough to worry about in the real world, and that you
can make a larger change by varying the spacing of the turns instead.


   I did some very carefully controlled experiments a while back
along these lines, and saw only insignificant changes in apparent
inductance due to changes in wire size.  (It was detailed in both the
QRP Quarterly, long form, and in Technical Correspondence in QST,
condensed.)  If you have a number of different cores which are
nominally identical, such as a half dozen T50-2's, and wind all of
them with the same number of turns but different sizes of wire (and
insure that turn spacing is identical for all coils--a critical
variable), you may see some noticeable inductance differences.  But
the cores are probably NOT identical, and the actual permeability can
(and does) vary from core to core; the inductance variations may
appear to come from different wire sizes but actually be due to a
combination of that and core-to-core permeability variations.  (If
you can get a Micrometals catalog for their powdered irons, look up
front--they cite inductance tolerances of plus/minus 5%.)

 In my experiments I carefully notched a T68-2 core around the edge
with a knife (each turn had its very own notch) so I could wind many
different coils on it with different wire sizes and be sure the turn
spacing was identical each time.  (It's well known that turn spacing
has a significant effect on inductance.) I used only one core to
eliminate the core to core permeability variation.  I also eliminated
the variable of turn spacing with the notches, so any inductance
change would (theoretically) be due solely due to wire size. That
would include, among any other effects, the differences in
distributed capacitance due to different diameters.  I repeated this
with a couple different core sizes, and variation due to wire size
changes was on the order of 2 or 3%. (On the T68-2 core with 16
turns, measured at 7.9 MHz, going from #18 to #28 caused an increase
from 1.47 uH  to 1.50 uH, or 1.7%.)

 My test equipment was a Boonton 260A Q meter.  While they are
getting pretty old now, unlike Rodney Dangerfield they DO get
respect, at least from the "old timers."  (They were very well
respected in their day, as well as high priced.  I have a 1964 ad for
them, and the price was exactly one half what my parents paid for a
brand new Chevrolet the previous year!)  Hardly new and modern, no
bells and whistles, full of vacuum tubes, but still good units and
lots of fun to play with.  The basic principle is a signal generator
feeding a tuned circuit, which consists of a well calibrated variable
capacitor and unknown inductance which you connect.  Tune for
resonance and read the Q off the meter, and inductance off a scale on
the capacitor dial if you're using certain test frequencies, or else
plug the capacitance and frequency into the standard formula to get
inductance.

 I also wound coils on many different T37-6 cores, all with the same
number of turns, to try to chart the variations in permeability
between cores.  (Remember, Micrometals, who makes those powdered
irons that Amidon sells, cites a plus/minus 5% inductance tolerance.)
I couldn't do the notching trick, of course, but wound the coils as
identically as possible.  How did I take care of the turn to turn
spacing?  I wound each one with the same number of turns (15), same
wire size, carefully chosen to just fill the coil completely.  I used
every last T37-6 in the house, eventually borrowed every T37-6 I
could from every local ham I knew, and by the time I was done I had
wound coils on 58 of them.  (Yes, it cost me a lot of wire, and yes,
it got pretty old after a while!)

The inductances were measured by resonating the coils at 14.0 MHz on
the Boonton, reading the capacitance off the dial and plugging that
into the standard formulas.  The inductances ranged from a low of
0.688 uH to a high of 0.745 uH.  The mean value was 0.722 uH and most
were clustered around it, although the two extremes are close to the
+/- 5% tolerance cited by Micrometals.  The moral here is that you
can have a number of cores which are nominally identical and yet
produce coils of somewhat different inductances.

There's a VHF amplifier project in some recent editions of the Handbook
that uses this approach. The coil is made of thin tubing that's mounted
between two PTFE (polytetrafluoroethylene) blocks. One of the blocks is
affixed to the chassis; the other is mounted on a PTFE leadscrew turned
by a front-panel control. The trick is obviously to mount the inductor
in such a way as to minimize slop and vibration.

I noticed in the pages of SPRAT that there is a QRP club
in Spain. According to the article, the club publishes a
newsletter (_QU-ERE-PE_).  I just sent off a letter to the
club contact person, requesting information on subscribing.
The whole process started me to wondering how many similar
QRP clubs (with publications) there are "out there" beyond
the great wall of terminals.
Looking through back issues of SPRAT (I joined in 1987),
I've found notices on Polish and Czech clubs, but they were
all set up before the fall of the wall. And then there's a
memory of an article in a now ancient QST (around 1968),
written by a ham in India. He'd designed and built a
completely solid-state rig (a marvelous feat, when you con-
sider the state of international trade and the condition of
India's financial system at the time).
Judging from the postings on USENET and from this mailing
list, there must be thousands of QRP-loonies out there. And
with all the non-British hams listed in the rolls of the
G-QRP club, I'd expect that there are local clubs in other
countries around the world.
So, to make short of a long ramble: Is there perhaps a list
of QRP clubs around the world? And where can I find it?

Gang: We all know that there are an infinite number of choices of

I've been having trouble with my system and I don't know if this made
it to the list.  I think it's intriguing enough that I'm sending it
again to be sure.  Please excuse the repetition.

Another old technique (an awful lot of this stuff was known by the '20s)
is to use two coils in series (or parallel), one fixed and one
rotatable. The rotatable one can either be inside or next to and in
line with the fixed one, and as it's rotated the coupling goes from
maximum (coils aligned) to minimum (coils at 90 degrees), corresponding
to maximum and minimum inductance.  Mechanically this is much more
stable and repeatable than turn scrunching.  I don't know how the
inductance will vary as the coil is rotated, but I suspect it starts
dropping gradually and falls off quickly at the end.  For our purposes,
we might want to limit the rotation to a few degrees or tens of
degrees.  The advantage of this method over a tuning slug is that the
required movement is a rotation (easy) rather than a linear
displacement.

BTW, if you rotated the coil a full 180 degrees the coils would fully
oppose, giving an even lower inductance.  Same principle as a
non-inductive wirewound resistor.

After slaving for hours to build up a little 40/20 meter TX to go with my R2
receiver for vacation, it turned out I had only one night available to try it
out.  All those Rocky Mountains... Funny what a 15-month-old will do to take up
your time on vacation...

Anyway, after throwing up a wire around 9:30 p.m. mountain time last Thursday
(in the Black Hills of South Dakota), then helping get baby to sleep with Mom
in the tent, I finally spent time at 10:30 trying to fiddle with the radio on
40.  As luck would have it, I had -- would you believe -- BROADCAST
INTERFERENCE!  At home, I have a 50 kW transmitter about 5 miles away which I
can see on my oscilloscope when I'm  careless with grounding -- and this rig
was fine there.  Imagine my chagrin when I heard such interference in what I
thought was the boonies...

Funny, though, it faded in and out.  Maybe it was a 40 meter signal --
religious broadcaster with country music would not be totally impossible.
Anyway, I just gave up for the night.  Not many signals anyway.

Admittedly, my antenna tuner was designed for balanced lines, and realizing I
had not obtained the wire to make my planned 40 meter loop, I just used the 50
foot end fed random wire I had used for a while.

Maybe now I can just enjoy the rig in my own backyard -- getting out of my
window-less basement shack...

I offered this on a semi-local distribution list on packet with no
takers--either no one wanted it or they didn't want to drive to
Severn to pick it up, so here's your chance--

Free (for shipping charges) to good home:  Relatively old, sort of
heavy, rather clunky frequency counter with somewhat limited
resolution.  (Not a pocket sized, 2 ounce LCD readout model with 17
digits.)  Watkins-Johnson model DRO-309A--the DRO probably stands for
Digital Read Out, and is obviously a plug-in part of some larger
electronic system although it functions as a stand-alone counter as
well.  (No charge since it was given to me free by someone when he
retired from the Coast Guard and went back to Alaska.)

Size is 8" wide, 3 1/4" high and about 16" long including knobs. Has
no cabinet--designed to slide into an open spot in the main unit,
whatever that was.  It's heavy, solid and well built.  Runs off
110/220 (selectable on rear).  Has 4 ranges:  0.1 to 50 MHz, 30-300
MHz, 235-500 MHz,  490-1000 MHz.  Inputs are through 3 BNC connectors
on the rear:  DIRECT/0.1-50 MHZ, "VHF LOW (VHF/UHF)", and UHF LO.

Display is red LED dot matrix (6 digits); legend over the display
says "MEGAHERTZ".  On the low range the decimal point is after the
first 2 digits, giving readout to 1/10 KHz.  On the other 3 ranges
the decimal point is after the 3rd digit, giving readout to 1 KHz.
No good for matching crystals for a homebrew filter but could be used
as frequency display for a VFO, signal generator, etc.

No clues to date of manufacture, probably in the '70s.  No idea what
sensitivity or maximum input level is.  I tried it on some HF
frequencies on a signal generator and got stable readings with about
3000 microvolts output (0.003 volts RMS).  On the other 3 ranges I
got stable readings with 10,000 uV, or 0.01 V RMS.  I checked it up
to about 400 MHz, the limit of my generator and seemed to work OK.
(See "Quirks" section below.)

Other features--switch and output BNC for DAFC, whatever that is; has
a non-functioning tuning meter (indicator for main system?); round
connector for BCD output (no data on pinouts available); has
capability of display frequency preset--off, internal presets, or
external input; internal/external range control (lets you override
the front panel range switch with external control).  I have no
documentation of any sort; W-J is still in business and may or may
not be willing to dig into their archives (perhaps at a large cost),
but basic frequency counter use is pretty straight forward. (I
haven't played with the feature, but if it still works you could use
the preset input to accommodate odd VFO frequencies.)

Quirks--sometimes displays random frequencies on one or more ranges
when there is nothing connected to the input, or even with a 50 ohm
termination, but connect the signal generator and it functions OK.
Also requires use of appropriate BNC input connector for the range
selected, or you can get other odd effects (and bogus readings) if
you don't have the "correct" one for the range.

If interested, reply by e-mail.  First request gets it unless there
are several messages waiting for me when I log on, in which case the
person with the best "story" wins.  (Estimated shipping charges well
under $10.)

Dear folx -

    Several of you suggested that I post my Dad's Sony 2010 for sale
on some Usenet lists/newsgroups.  After asking around, tho, I guess we do
not have access to Usenet groups.  So I'm asking someone a favor:

    Would someone mind just copying the message below and posting it
on one of the Usenet groups like    rec.radio.swap
                or    rec.radio.shortwave.


    My message has instructions about responding to me via email, so
I think this one post is all you'd have to do.  I would much appreciate it.
Here's the post:

Folx -

        I have a virtually new Sony ICF 2010 short wave receiver for
sale.
Actually it is my Dad's.  Mother got it for him (on my recommendation),
but he didn't ever use it.  So it's still in its original box, all
original packaging, etc. They're asking $300 for it, firm.

    I am not able to read this or any Usenet group, so someone has
been kind enough to post this for me.  You can respond to me at the
following addresses.  Many thanks.

In reply to one of my recent 'grams, Jack, W5TFB, asked what happened
to the Q of the coil on the T68-2 when I compressed the turns from a
30 gap all the way to a 270 degree gap.  I hadn't bothered to record
it, so I dug it out and checked it again.  The answer is, "not much."
Here are the results; since the original spacings are impossible to
duplicate exactly, the values are somewhat different.

Core:  T68-2, 16 turns #18 wire, measured at 7.9 uH.

30 degree gap between ends of the coil:  1.641 uH "apparent
inductance", Q 221

90 degrees, 1.737 uH, Q 224

180 degrees, 1.962 uH, Q 217

270 degrees, 2.425 uH, Q 217

I'd take these Q figures with a quarter of a grain of salt, since
this is read off an analog meter scale (albeit a rather large one)
and thus subject to a bit of interpretation.  The main point, though,
is that there was not much change in Q when the turns are compressed.
(All the gaps shown were eyeballed and are not exact.)

By the way, as with all previously reported experiments, this was
done on a Boonton 260A Q meter.  Although I show values to three
decimal places, such "precision" is going to be virtually
unattainable, unrepeatable, and unnecessary in actual practice.  For
each measurement the coil was resonated with the variable capacitor
in the 260A, the value (to a tenth of a picofarad) read off dials of
the main and fine tuning caps and plugged into a calculator. (The
fine tuning cap dial is calibrated directly to 0.1 pF points, the
main dial to 1 or 5 pF, depending which end you're on.  And no matter
how carefully you set the main dial to the nearest 5 pF mark, you
have to be just a tad suspicious of the reading on the fine tuning
dial!)

Calculators are neat devices--they give you answers to a gazillion
decimal places, even when more than 2 or 3 are utterly unnecessary
and, practically speaking, meaningless.  I arbitrarily truncated the
answers at 3 decimal places, but in the real world one place would be
more appropriate.  (After all, you can very easily get a 10% or
larger change in inductance by varying the spacing of the turns.)
These figures imply a precision in the coils that does not exist;
they are simply a reflection of the exact value at that instant, and
may never be seen again.

As Zack Lau said in Tech Correspondence in the June 93 QST,
"...home-brewed inductors are rarely precision components.  Why
specify their inductance to three significant digits?  Sometimes,
even two significant figures is a bit absurd."  And I heartily agree
with all of that!  While it's OK and educational to do it in a
tightly controlled experimental setting, in the real world you'll
never be able to duplicate the inductance value to that
precision--and there is rarely any need to.  (Circuits often contain
variable components which can compensate for slight variations in
inductance, and the inductors themselves can often be varied.)

When I first started studying inductors several years ago (when I got
the Boonton) I asked one of the truly brilliant (in both theory and
practice) electrical engineers in my ham club some detailed questions
about inductance and designing inductors.  He told me the simplest
thing was to forget much of the detailed theory, variables,
microscopic permutations and oddball physical effects; just wind a
roughly designed coil that was in the ball park and trim it until it
worked as desired in the circuit.  At the time I thought he was being
a wise guy, but over the years I've come to realize he's right
(except now I know why, and have a much better understanding and
appreciation of the identity and effect of all those factors).  There
are so many variables in both the inductor and the circuit that you
can drive yourself crazy trying to account for all of them.

This station Class 1E, at home, on battery, using an ARK 4 and a
folded dipole at 40 ft., worked 90 stations on 40M CW at 4 watts out.

Location: 84.00 W, 35.48 N, near Knoxville Tn.
Inet QRP'ers worked: None

Comments: Worked about 12 hours out of the 24, started duping stations
          toward the close.  More difficult to make contacts than
          a QRP QSO party.  Need a better QRP strategy. Tried "channel
          master", "in your face", and "hit and run". Nothing works well.
          About two contacts per frequency change.  Need a preprint of
          all of the ARRL Section ID's in the cockpit next time.
          Propagation seemed normal. Some QRN due to thunderstorms late
          Sunday.  40 meters was enough for me.  Really didn't miss 20
          meters like I thought I would.  No 6's or 7's worked.  7ah
          gel cell down to about 11.7 volts at close.

I actually managed to get on and do Field Day; I operated about 8
hours, total, using an antenna I lashed up against the side of the
house Saturday morning (in the rain, of course -- this IS Field Day,
after all) [40 meter inverted vee with a 20m inverted vee hanging from
it -- lamp cord (unzipped)]; I used a QRP Sprint on 40m (1W), and an
NN1G II on 20m (2-3W), operating from my garage on Saturday (lacking a
suitable umbrella) and from the driveway on Sunday (acquiring the
official Field Day sunburn); power supply was batteries (one 1.9Ah
battery for the rigs, and dry cells for the light (hey, might as well
go whole hog.  Well, half hog:  when I went in for dinner, the
refrigerator wasn't on batteries ;-).

Grand total:  21 contacts (one dup).  Yow, have I won yet?   :-)

All of the contacts were made with the Sprint; I believe the NN1G must
have been set for the "wrong sideband" (i.e. TX LO below the BFO, not
above it where it belonged).  In fact, in true FD style, I spent an
hour and a half trying to fix it during the contest (but I had to use
my AC-operated WWII-vintage aircraft receiver to help calibrate it, so
I guess I'm further off of pure battery operation :-), and though I
*think* I got it set right,

    [interjection:  how in the world does one accurately measure
     the frequency of an NE602 crystal oscillator when touching
     any point in the oscillator circuit with the frequency meter
     probe shifts the frequency dramatically???]

                somehow in the process the receiver mute
got screwed up:  my first attempt to contact someone nearly blew my
head off, and due to fumbling around and the general problem of being
30dB below everyone else, that contact got lost and I gave up on 20.

The Sprint, by comparison, behaved flawlessly.  Unfortunately, it is a
direct-conversion receiver.  Not all of you may have tried operating
FD with a direct conversion receiver.  I heartily recommend it --
once.  :-)  40m in the morning and afternoon wasn't too terribly
crowded, so I had relatively little difficulty separating signals, but
once the band opened up it was brutal.

I don't think I picked up any of the internet crowd, but notable
contacts (for me, anyway) were W1AW (turned on the receiver this
morning, and there they were; finished the contact before the receiver
stopped drifting :-), and W1EEL (whom I should send a card).  I don't
know how other people found conditions, but it seemed like all I heard
were 1s, 2s, and 3s (and a couple of 8s) -- could someone please
assure me that there actually are hams in states other than NJ?  :-)

Well, back to debugging the NN1G again, and I had fun.  1W with a DC
rig may be the hard way to do Field Day, but it worked better than I
would have thought.  It also would have helped if I didn't have to
listen to most stations for 6 or 7 contacts just to figure out what
their exchange was (I think my code speed improved :-).

RIG : OHR Classic (5 watts CW - 20 & 40 meters)

ANTENNA : half-wave vertical wire - supported by a kite.

POWER SOURCE : 12V Ni-Cad battery pack

TOTAL ON-AIR OPERATION TIME : Less than 8 hours


FINAL SCORE:
       73 QSOs on 40
       35 QSOs on 20
     -----
      108 QSOs (x2) CW   (x5) 5 watts   = 1080 points

                 TOTAL SCORE            = 1280 points

COMMENTS :
    The thunderstorms never materialized but the winds more than made up for
    it.  High un-cooperating winds kept the kite antenna from flying early
    Saturday afternoon.  Finally (with a longer tail on the kite) operations
    started shortly after 2100z.  Operated from the beach from about 5 PM
    Saturday until dark and then returned 9 AM Sunday.  40 meters was much
    better than expected.  20 seemed much worse than last year.  Tried a
    couple CQs and worked 3 stations.  The rest were all from just tuning
    and calling.  In general, worked about 80% of what I called.  I finished
    off most QSOs signing /QRP.

    My personal goal was to make twice as many contacts as last year.  Even
    with a late start, I managed to reach my goal with 3 QSOs to spare.


LESSONS LEARNED:  ;-)
    Delta kites do not like high winds unless they have a *very* long tail.
    A half-wave vertical on 20 works better than a full-wave vertical.
    Use a dupe sheet next year.  Memory starts to fail after about 50 QSOs.
    You can still get a nasty sunburn even under a beach umbrella >ouch<

First of all, let me say that it is great to finally get hooked up with the
Internet QRP group. I'm really enjoying getting all the mail to read and look
forward to seeing lots more from everyone. I'm reaching the group by way of
America On Line's Internet service. I heartily recommend it to anyone who
can't reach the Internet directly.

With my wife out of town till Saturday evening, little league games for all
three of my sons on Saturday, and a birthday party on Sunday, I was really
expecting Field Day this year to be a real bust. For the last few years I've
been dreaming about getting a group of QRPers together for an all homebrew
effort. With everything going on, there was no way that was going to happen
this year. I was determined, however, to at least get a little time on the
air.

The rain Saturday morning left us here in South Bend, IN about noon, so I
decided to take my NN1G 20 mtr rig out on the deck for a few QSOs. First step
was to run to the local Radio Shack to get 30 feet of zip cord speaker wire.
This I fashioned into a crude dipole which I strung from the roof gutter to a
tree out back. I finally got everything up and running by about 2000 UTC. The
weather was beautiful and, upon firing up the rig, I found that radio
conditions sounded great too.

I spent the next 3 1/2 hours at it and managed to get answers from most of
the stations I called. Total contacts for Saturday - 30.

Sunday morning, I awoke to a bad thunderstorm. It rained steadily till about
1800 UTC. When things finally dried off, I hauled the "stuff" back out on the
deck and managed another 12 QSOs. One unusual problem I had that made copy
difficult was all the local "QRM" from all the birds chirping after the rain!


I didn't hear any familiar QRP op calls but expect that at least a few of my
contacts were with other QRP stations. I was pleased with the way the NN1G
rig worked for me. I've used it for a couple other contests and have logged
over 200 QSOs with it. Maybe next year I'll have rigs for 40 and 80 to go
with it and will be able to mount more than a single band effort.

Final tally - 42 QSOs in 6 hours,  no sunburn, only a couple mosquito bites
and a rather enjoyable weekend - even if it was only a solo effort.     72,
Tom N9DD    [e-mail]

There's a ham radio "channel" on the IRC (Internet Relay Chat) I have access to.
  Had a few interactive "QSOs" on it, but can be a real time waster when you

From a car radio, no doubt.  I first saw this when I tried to move it up to 160
meters.  The gearing on mine was not real tight for tuning purposes.

So it is.

This is contrary to some wisdom that floats around that a dead-bug VFO over a
ground plane can be more *electrically* stable because of fewer random
capacitances.  Perhaps an etched board is more stable *mechanically*, but I was
pretty successful in my dead-bug VFO using older, large components with heavy
leads.

Good ol' basic point to point for me.

This can be remarkably compact.  I just built up the smallest VFO/transmitter
for 40 and 20 meters I could with standard-size components. I made each stage a
little "cluster" of parts that was pretty much self supporting on one or two
ground leads soldered to a PC ground plane.  My .1 uF bypass caps were a bit
large, about 1/2 inch diameter, but they could be tucked flat under the rest of
the parts with the leads sticking up.

Quality unlicensed stuff in those days...

Speaking of which, anybody remember the Internation Crystal kits and devices
for the hobbyist?  Believe it or not, they offered a setup for 100 mW tone-
modulated CW on the Citizens Band -- you would put the TX unit at the antenna
to get around the restrictions on antenna/feedline length, and they said you
could legally work DX this way, being unlicensed!

Was this for those who could learn the code, but not able to pass the theory?
I'll bet they sold a ton of those ;-)

Subject: T-368 transistorization
Sender: [e-mail]
Precedence: bulk

Here's my periodic plug for transistorizing the T-368 for homebrew use.

It's a beautiful (and bulky, but this is the reason for its stability) 1950's
piece of Collins military gear.  A 1.5 to 3 MHz PTO, doublers to go to 3-6, 6-
12, and 12-24 MHz, and a driver tube.  And a mechanical digital readout with
very tight gearing -- no backlash even when multiplied 8 times!  Real stable
even in its tube state -- and transistorized, this baby won't move!  You can
get them, I last heard, for $45 from Fair Radio Sales.  One of the most useful
pieces of military surplus gear for today's use!

Since building a more compact VFO/transmitter for portable use, I can
appreciate how incredibly stable the T-368 is.  Even following all the
precautions the books tell you, with my professional musical ear, I can hear
the drift in my homebrew job.  Going back to the old/reworked T-368, even on
its top range, I feel like I can hold my own with any synthesized rig.

I have 14K of text about my transistorization and RIT modifications.  Lemme
know if you want it.

I'm having similar problems with Yuasa batteries available at our local surplus
house.  The NP1.2-12 is rated at 12V, 1.2 Ah, and can be charged at up to 15
volts for cyclic use according to the label.  Well, I do that overnight, and it
drops to about 13 volts after a short time.  Under load, it drops below 12
volts even with about 200 mA -- interestingly, the R2 receiver board doesn't
like that low a voltage.

Another battery, a pair of Yuasa NP10-6's in series, is rated at 6v 10 aH (each
battery).  It drops to 13 volts after being charged at 15 volts (again per
label), but stays there under load.  It has been able to power my Ten Tec
Argosy at 50 watts for a reasonable length of time, and of course can handle my
QRP setup with ease.

Are these "over-aged" batteries?

   Well, since I've seen several other FD results posts I thought I'd
drop mine in here too.  I ran 1A Battery (that's what I told everybody
at least - I was the ILQRP station, in the parking lot of our
apartment using a pair of 105AH Marine batteries charged for the last
2 months from a 4.8A solar array).
   Before FD started, I found 6 was open.  Made several contacts,
including HH7PV.  Even called CQ a few times *and had people come
back* running 8 watts peak (if I yelled) SSB.
  6 stayed open most of Saturday, and opened up again on Sunday
morning.  10 was somewhat open, if you ran some power it worked (60
watts pep, made 3 contacts, hardly worth the battery drain).  2M SSB
late Saturday made a very few contacts, also running power (100
watts).  QRP on 432 was a real bust - nada.  The antenna is pretty
directional, and the oldradio's ears are nothing to brag about these
days.
   Total was about 60 stations QRP on 6m, 3 for kicks QRO on 10 and
another 3 rag-chews on 2m QRO.  Got Alabama, Florida, N. Carolina,
Arkansas, Texas, Georgia, Nebraska, Colorado and Wyoming on 6m.
Antenna was a shortened dipole at 30 feet.  Operated probably about 8
hours, had the radio on as background another 3.

Mike Czuhajewski posted that the change in Q for a toroid
varied very little with the compression of the turns from
30 degrees to 270 degree angle.

The Q for a parallel resonant circuit is X(L)/R, where R
is the resistance of the coil and X(L) is 2*pi*f*L.
Since the resistance of the wire doesn't change (it is
fixed length) the Q won't change much.  Here is what
does change.  The resonant frequency of the LC circuit
will be lowered due to increased capacitance distributed
through the coil with the closer winding spacing as it
is compressed.  Remember boys and girls that the resonant
frequency is 1/(2*pi*sqrt(L*C)), thus with increased C
the frequency is lowered.  If f is lowered then Q is also
lowered since X(L)=2*pi*f*L and I'm assuming that L is
not changed (see K5FO newsletters).  Thus Mike's measurements
seem to indicate that this is true as he shows a lowered Q
value and the windings are compressed.


Good work Mike,

I have had many QRO types request my card because they were impressed that

Howdi,

hope eveyone enjoyed Field Day. Our University club made a
decidsion that it was more important for the prospective hams and
new hams to get interested and operate and learn, than to stack up
points.

I decided this was a good opportunity to put some of my newer rigs
through their paces. I was VERY impressed with how well the MFJ
20m SSB performed.. with no extra filtering.. had no problem
working anyone I heard.

I also was impressed with the performance of the Oak Hills Classic
on both 20 and 40.. seemed to really get through and the
selectivity was great.. also used it with no additional filtering.
The ARK 4 did real well.. kept the audio filter in the narrow
position (but I always do.. did the newest mod on it without
blowing up anything).. for some reason.. the Classic seemed to get
through a little better than the ARK4.. maybe voodoo or just
luck.. but that is the way it worked.

    Well, if you come onto 10meters probably the best area is the
novice/tech segment from 28.3 to 28.5.  You stand a good chance of
finding some like minded folks there (it's where I hang out on ten,
mostly due to the license :-)  ).  Within that segment, I'd say its
wherever you can find a QSO!  :-)

    Some folks claim 28.4 to be a general calling frequency, although
that isn't universally recognized.  Also in general, the area from about
28.480 to 28.500 is sort of a non-contest DX window - this seems a bit more
generally recognized that the calling freq.

    There are a number of nets that meet below 28.4.  I know there are
some paperchasers that hang out at 28.345 or thereabouts.  A couple
others meet on 28.380 and/or 28.390.

    Watch out for 28.325.  There are some mealy mouthed, mean spirited,
nasty talking, obscene jerks that sometimes refer to themselves as the
"lid net" who like to stay on that freq. for hours.  The FCC listens to
them frequently, so I'd advise anyone to stay away from it lest your
call sign get accidently caught up in the mess.  I have heard these guys
pirate someone else's call, which is bad news.

    The worst of the lot was (I think) N5RLX or at the very least,
somebody who likes that callsign.  I think all these guys are located
in Texas or nearby.....

    There are a number of folks who respond very positively to QRP
ops on that segment of 10, but keep in mind that with the sunspot cycle low
as it is, 10 is REALLLLLL spotty these days.  Sometimes there is some
good medium distance skip, I'd say in the 500 to 1200 mile range, and
sometimes it is as dead as a brick.  Not sure when the lowest of the
low in this cycle is supposed to occur (quite possibly about NOW), but
for those who have never experienced ten when it was GOOD, I can tell
you that in 1988-89 ten was absolutely red HOT.  A few watts would work
anywhere in the world, especially during the winter months.

    Seemed like you couldn't HEAR the locals for all the DX!  :-)

    Sure hope we get that again on the next cycle high....

          My first Field Day since 1970 (when I operated as a Novice) and
          did I have fun!

          I set the station up along the top of a ridge in the Sierra
          Nevada mountains (about 5500 ft).  This was reached by a
          half-hour hike/climb from the little town of Long Barn with a 20
          pound day-back (containing HW-8, Gel Cell, MFG Tuner, sandwiches,
          etc.).

          Found a nice open spot with a great view of the mountains, and
          proceeded to string up my G5RV.  In the process, Murhpy struck -
          while throwing wires into trees my prescription glasses fell out
          of my shirt pocket.  Spent 40 minutes searching through
          pine-needles and brush - finally found them - the thought of
          spending several hundred dollars for a new pair was a great
          motivator.

          Set the rig on a stump and used a log as a chair - turned on 40
          meters, and the first thing I noticed was the COMPLETE ABSENCE of
          electrical noise - I hadn't been aware of just how high the noise
          floor was in the city.    Tuned around, heard a CQ FD, answered,
          and got a reply!  Heard another CQ FD, answered, got another
          contact.  Hey, this is fun!

          I finally quit after about 5 hours - I'd run out of water (the
          ridge top was HOT), the log/chair was becoming more and more
          uncomfortable, and I'd spent the last 20 minutes tuning around
          and hearing only stations that I'd already worked.  But I'd made
          almost 50 contacts, from San Diego to British Columbia, all on 2
          watts.  And almost all of the contacts replyed on my first call.

          Next time:

                1.  Bring a QRP SWR bridge - the one in the MFJ tuner does
          NOT cut-it (I'd brought along another more sensitive bridge, but
          forgot a BNC/SO-239 adapter.  I tried 20 meters, but I could
          never tell if the antenna was properly tuned.).

                2.  More water!

                3.  Bring a compass.  (Antenna ended up facing close to
          North-South, mainly because that was the clear shot off the
          ridge).

                4.  Do NOT use a direct-conversion rig.  Too much QRM from
          the images.  (Next year I hope to be using a SIERRA!).

In the quest for a small, linear variable inductor, would it not be
possible to place a second small winding on a toroid, then feed that
with a variable DC voltage in order to change the permeability of the
toriod material? The inductance wouldn't vary linearly with the current,
but that could be compensated for in any number of ways.

I've dug out my copy of Kraus's _Electromagnetics_, but I can't find an
answer that I can comprehend in the time I have available for this!

COMMENTS :

You can do FD with just a 2m FM handheld.

The good front end on the HTX-202 saved me from most of the ravages of
intermod. This site is on the top of a Captitol Hill which is more a ridge
or escarpment than a hill and shares a good all round view of Seattle.
Consequently it has a whole host of TV, FM, and PMR etc etc transmitters on
the top of various buildings and towers. Fortunatly none are in the park
itself.

My first problem was not working the people I called until I realised I had
the  "low(er) power" button on. Unintentional milliwatting! Moving to QRO
(2 watts) meant I could work almost all heard (except one).

The tower is an brick enclosure around the water tower proper. The windows
at the top have heavy iron fences and wire lattice work. Careful
positioning of the antenna gave both full power with the antenna a little
outside the grating. Those grating really do detune the antenna.

Best "DX" was W7KM who was 1B about 10 miles NW of Mt Rainer, about 50 to
60 miles south of Seattle and probably line of sight from my QTH. He had a
fully quieting signal.

I also worked the Mike and Key club at Fort Flagler, K7LED. They're about
50 miles to the north on the Olympic peninsula. I was their novice/tech
station last year.

Wore my "QRP is not for cissies" T-shirt and carried a copy of QST and
tried to explain why I was shouting gibberish into this black box!

After an hour I packed it in and walked home to watch the World Cup (hey,
I'm English, what do you expect!)

LESSONS LEARNED:

I really need an external antenna I can poke through a 1" dia hole -- a
dipole will suffice. Carrying an external antenna with the HT is probably
not a bad idea.

The HTX-202 real does have a good front end.

Packet would be fun from this location (heard quite a bit of packet
activity). I have a cheap T1000 just need the modem or TNC.

I need to bring a table and chair to sit at. I would look more respectable!

You can make more points for location and power than making contacts. This
would be particularly true if one picked up all the bonus points! Could be
an amusing goal.

You don't have to work HF to have fun, even 1 hour of 2m FM can be amusing,
and its probably closer to what would happen when the big one hits.

The capture effect on FM can make sharing a channel difficult, but I was
amazed how the several folks on the same channel shared time although we
could all hear each other (we all worked each other). Directional antennas
would help here.

The ARRL should designate particular simplex channels for people to camp
on. Most of the contacts were on 146.52 (which is probably verboten by the
rules). Even in a big urban area at a reasonable location I didn't hear
many people but I had a great view to the horizon all the way around.
Perhaps many of the new techs don't know why they should try FD or think
that its a HF only event or think that VHF contesting is SSB/CW only. I
think I feel an "New Ham" article coming on!

But one should point out that the "short skip" (sporadic E) season is now
approaching its height and you should see good sp-E on 10/6/2 (in fact that
has already been reported here).

Something I forgot to mention in my FD description:  I got my first ticket in 1976,
about 1 month before FD.  This time around, it has been about a month
since I got back
on the air after an absence of several years.  Unfortunately, unlike the first time
around, I haven't had enough time on the air to practice (thus FD was my contacts #
2 through 22...).  I used to do FD with the Boeing Employees Amateur Radio Society
(hence the old interclub rivalry mentioned above :-).

I was 15 meter team captain for VE7BAR (3A BC), a mainly QRO (100
watts) FD operation.

We did, however, charge some NiCds from a solar panel and make
some contacts with an HW-8.

Other highlights included the 15A (!) station in Santa Barbara
who told us to Have a Nice Day, and causing pileups on 10 (wide
open with sporadic E) by innocently calling CQ Field Day.

I'm toying with doing my own B or E station next year. My mom and
dad live out in the country in the B.C. interior, with lots of
land for stringing antennas, and minimal RF noise.

Actually, I thought FD actually ended at 2100Z (with only A&B stations who
do setup starting at 1800Z Saturday able to use the whole 27 hours).  I had
planned to get on at 2100Z, but wound up having to go food shopping instead.

Mark (NX1K) is our FD captain, but he's going out of town for the next week
or so, so I'll take liberty of writing up this quick summary to the list.

Some of these guys had been coming to this site for five years or so, but
this was my first time there.  It is at a small wind farm high on the SW
side of Mt. Wachusett in central MA (section WMA), about 1500' MSL.  There
are 7 wind-powered generators around the site (used to be eight until one
was obliterated by lightning; we got to see some of the twisted remains in
a barn).  It was quite a thrill the first time they kicked on (they are
fired up when the sustained winds reach a certain level).

Tempting as it was to use the ~100' windmill towers to hang antennas from,
we weren't supposed to and didn't.  There was a line of ~45' trees on the
uphill side of our clearing, and we strung wires from them.  We ran 3A
battery, focusing on 80, 40, and 20.  It was foggy all day Saturday, rained
for a while Saturday night before becoming beautifully clear for late night
and Sunday.

I was band captain for 40, and I made a vertical fullwave square loop hung
from the top of the trees, with the bottom side about 8' above ground.
Since the terrain falls off rapidly, antenna height isn't a big deal there.
I was nominally in charge of 15m, too, but I just loaded up the loop for a
while on Sat afternoon.  Rig was my HW-9 at 4W for most of the contest, but
used W1FMR's NorCal 40 for an hour or two on Sunday morning with equal
success.  We started off very slowly on 40/15 (about 3 Qs per hour for the
first couple) until I figured out that my HW-9 was transmitting about 1khz
below where it was receiving! Oops; worked fine back in my shack, but it
must have gotten jostled out of alignment around in the car on the way
over.  That's what FD is for, I guess.  Adjusted the RIT to compensate, and
the Q-rate went way up!  Count me in among the fans of the NorCal 40; it
got me really excited about the Sierra!

Greg (WA1JXR) was band captain for 80, and hung a ladder-line fed dipole
from an uphill tree to a downhill tree; a perfect sloper to the west.  He
was running a Kenwood TS-450 and had rig PLL problems on Saturday, but the
rig started working again in time for the 80 push Saturday night.  He ran
out of battery on Sunday morning (those power-hungry commercial rigs!), but
I had a spare 24AH to get him back on to load up the long dipole on 15.  He
was working a great rate Sat night!

Jim (W1FMR) was band captain for 20, and he set up a delta loop on 20 and
ran a Ten-Tec Argo 509.  No problems there that I know of, except that I
think his speaker was louder in the 40m station tent than in his own.  He
can tell his own war stories!

In general, it was a blast.  Great site.  I finally got to meet several of
the people I know from this list.  Dave NN1G even stopped by on Sunday.

I got the OHR Wattmeter built just in time for FD (Friday night), but with
one minor glitch: the reflected power reading always about the same as the
forward power.  Oops; no time to debug it then....I'll do that this week.

I *rely* on contest contacts to add to my DX country total. I now have
about 115 worked, and 98 confirmed and well over half were from contests
and most of them from the annual CQ Worldwide DX contests. I have found
that contest stations are among the *best* QSLers.

Duane all but comes out and says the first rules of QSLing: if you want
the card, do what it takes to get it. I have been working toward DXCC so
my focus is on overseas QSLing.  I have never used IRCs, but use US dollar
bills instead. I used to use $1 but with so many postal rates going up in
different parts of the world, I now always include $2.  I always include
a self addressed envelope. On the inside of the flap, I stamp my callsign
and write down the QSL information: call sign of station worked, date,
time, band/freq, and report. This is so (1) the person opening the outer
envelope knows which card my return envelope goes with, and (2) if my card
gets separated from the envelope or otherwise destroyed, the data is some
where so hopefully I'll get a card anyway. Remember that the person
answering the QSL card may be a manager for several stations so make things
easy for him or her.

As for QSLs within the USA, I always include a SASE. I am about to get
serious on 6m and perhaps 2m as well, so I am going to be doing a lot of
USA QSLing and I will want the cards!

Finally, Duane wrote:

For those hams who don't have cards, you could always keep a supply of
"form letter" cards on hand, i.e., a card that you "make" for him or her to
sign. Fill it out with his call sign, your QSO data, and send it with your
card for him to sign and return to you. Remember that if you want confirmation
of QSO, even a handwritten letter/note will do, but it must be *signed* by
the operator.

I must take issue with the tone of Duane's comment here. In my mind, QSLing
is not an obligation and no ham should be chastised or make to feel guilty
if he doesn't choose to print up QSL cards. Furthermore, I don't buy into
this "the QSL card is the final courtesy" and initiating a QSL card for each
and every contact I make. I know exactly where USA QSL cards end up at when
sent to a rare DX operator: in the trash. The last thing he needs is his
ten millionth card from the USA!  There is no point wasting your time and
his if you don't want his card. I go back to what I said earlier: if *you*
want a QSL card, then *you* have to do what it takes to get one, i.e.,
initiate the request, provide return postage and an addressed envelope, and
include a "form letter" card if you have to.

I didn't try hard because I wasn't feeling well (are there equalization
multipliers for poor health as well as being in or near the Black Hole?).
Did 1E battery with 5W out to 2-el quad but had the tower down to 20ft
because of real good thunderstorm Fri night (one local lost all his rigs
due to nearby lightning hit).

Made one satellite contact on RS-10 and about 40 contacts on 15 + 20m. It
was the first chance I have had to try out the CW filter I designed for
the W9GR DSP kit. IMHAUO (And Unbiased :-) it worked rather well. It is
centred on 780 Hz for my IC-735's sidetone and has a nominal -6dB
bandwidth of 100Hz. I forget the shape factor but it's pretty good. I
found the 250Hz one from W9GR to be a bit too wide for this kind of
"contest" conditions and his 30Hz filter too hard to use. 100Hz seems to
be about right.

If you have the single function version of W9GR (single function PROMs
won't work with the multi-function version) and can blast your own bipolar
PROMs then you can get the Intel hex via anonymous ftp from ftp.usask.ca in
pub/amiga/w9gr/cw780-100.lzh (which is an lharc archive). If anyone can't
read a .lzh, I'll just explode the files into ascii - they're not all that
big.

                              Sunday I was free of obligations, but the band was
                              pretty crappy. Checked WWV and sure enough K-index
                              had taken a major jump. Oh well!

COMMENTS :
Next weekend I should be up in the cool pines partaking in my belated FD
effort. 7,000 ft. up the daytime temps should stay around 85F. Will toss
a wire into a pine tree, and operate OHR 20M QRP rig on and off. Hope to
run across a few fellow QRPers this weekend. I listened this last weekend
but did not hear any of the internetters. 73 - Mark.

FD 94, Zuni Looper Style
by Doug Hendricks, KI6DS
862 Frank Ave.
Dos Palos, CA 93620
[e-mail]

The Zuni Looper Mountain Expeditionary Force was represented this year by
the following: Fred Turpin, K6MDJ, Keith Clark, W6SIY, Ralph Irons, AA6UL,
Kim Irons, KD6WJK, Rob Roberts, N7FEG, Bill Young, WF6D (+ grandson Chris),
Charlie Lofgren, W6JJZ, Wayne Burdick, N6KR, Doug Hendricks, KI6DS, Clark
Turner, WA3JPG and Belinda Turner, KC6TKO.  We were missing old stand by's;
Cam Hartford, N6GA, (in Europe), Jim Cates, WA6GER, (unable to make it from
Sacramento), and Richard Fisher, KI6SN (ill with the flu).  Chuck Adams, K5FO
was to have made his initial appearance, but was a no-show.

We used the call N6GA, as Cam had appointed Keith as a control op.  We
operated 5A from LAX with the following rigs: OHR Classic, NorCal 40, Sierra,
Argo 509, Argo 515, Kenwood TS130, Icom 735, and a couple of other commercial
rigs that I forgot to get details on.  I was too busy having fun!!

The Zuni's are famous for their antennas, and this year was no exception.
We had a 4 element Quagi up 90 feet on 40, 3 Phased elements on 6 meters,
the Six Shooter on 20, a 5 half wave loop on 80, ZL special on 10 and 15,
G5RV, and a Skelton Cone.

We were short on ops this year, so the decision was made to have a "social"
Field Day.  We would try out all of the home brew rigs that were there, take
some time to visit, and make contacts as they came.  Wayne, Keith, Ralph and
Fred made most of the QSO's, the rest of us made a few, but we all had fun.
I don't know how many QSO's we made, as Wayne and I had to leave early for
the 6 1/2 hour drive home, but will report later when I have the results.

Field Day with the Zuni's is never boring, i.e. the famous "Bob and the Bear"
story, and this year was no exception.  I was putting up the Skelton Cone
and had just finished at 11:00.  Boy was I proud, it was up at 50 feet, in
a perfect configuration, and I was hurrying over to have Keith and Wayne look
at it, when I looked up into the sky and saw the camper's worst nightmare,
a FOREST FIRE!  Folks, this thing was big, and was getting bigger in a hurry.
Smoke was billowing up into the air, and the scary thing was that it was
close, about a mile from us across 2 ridges.  Several others saw it at about
the same time, and we gathered together to watch and discuss our options.
Fred got on the 2 meter repeater and received a report that it was out of
control and that we should alert the others in the campground to be ready to
evacuate on a moments notice.  So, I guess we get extra points for relaying
emergency traffic!!

The next 4 hours was spent nervously watching CDF airplanes fight the fire.
We had a great seat and it was neat to see the borate bombers do their thing.
I have the upmost admiration for those pilots.  Talk about a dangerous job!
Luckily for us the wind was blowing towards the fire and kept it from
spreading our way.  But, it did nothing for our scores.  The fire was still
not under control when Wayne and I left Sunday morning, and it had burned
several hundred acres, 7 structures, and did huge amount of damage.

Finally we decided to get back to field day, and we went to our separate
stations.  About this time Clark and Belinda arrived, with yet another
story to add to the excitement.  On the way in to the campground, they lost
the brakes completely on the Volvo.  Clark said that his heartrate increased
dramatically when his foot went all the way to the floor and there was no
response to the brake pedal!!  Thank goodness he was able to gear down and
use the emergency brake to get stopped.

Field Day was fun.  The homebrew rigs performed really well, and the NorCal
40 and Sierra both passed the test.  Wayne said that he was happy with how
the Sierra worked and he just wants to make a minor tweak or two in it.  But
he had a big grin on his face when I asked him how the Sierra worked.

Another highlight was when Kim came running out of the tent, yelling, "I did
it, I did it, I made a CONTACT!!"  It was her first HF qso, and we all looked
at her and grinned.  I know I was thinking of the first qso that I made and
what a thrill it was.  Sure was neat to be there and enjoy Kim's first qso.
It brought back fond memories to all of us.

As we were packing to go home, Bob Heussner, K6TUY, a NorCal member from the
LA area drove up.  He came all the way up to Table Mountaing hoping to meet
Wayne and I.  That's what he said, but I think the real reason was to see
the "Sierra" that he had ordered.  It was really nice of Bob to drive up to
see us, and Wayne and I both appreciated his efforts.

There you have it, a brief account of FD, 1994, for the Zuni Loopers.  Oh,
by the way, Chuck, I had to eat the huge New York Strip that I brought for
you.  It was delicious.  The other Zunis want to see if you can really do
60 wpm, as they think you chickened out!!  I tried to defend your honor, but
it was difficult.  See ya next year.
72, Doug, KI6DS

    True, although sometimes it would be nice if they'd even acknowledge
receiving your card by taking a pre-stamped plain post card and writing on
it "yes, I got it - go away!" or something like that......

    In self-defense, I *did* include a smiley face which is the
internet way of suggesting some humour is intended.  I think when combined
with my other comments about the cost of QSLing, it can be seen that
this was a bit of humour.....

    In reality, I generally have to agree with the writers comments
about being obligated and so forth.  I definitely do NOT even attempt to
send a QSL card for every contact *I* make, primarily because the time
I'd spend doing so, for one thing, could be better spent on the air
MAKING contacts (or any one of a hundred other things that need to get
done).  For another thing, the postage alone would kill me, and I'm
not even a real MAJOR ham player!  Guys that spend more time on more bands
than I could conceivably wrack up one hell of a bill just doing QSLing.

    Which for many people, is why there are bureaus.....

    If someone asks for my card, I send it.  If someone is a contact
I need confirmation for, I send it.  If someone has an interesting callsign,
I send it.  If someone tells me he has a rather neat QSL card, I send it.
(there is a lot of humour in certain cards, if you haven't noticed.....)
Certain special event stations have rather attractive cards/certificate,
and so I send for them.

    I will take issue with what I perceive as a widespread and
often incorrect attitude regarding DX or rare DX operators - that all US
cards automatically go into the round file AND DON'T GET ANSWERED.  Yes,
I know that isn't precisely what the writer said - but his comments on
the subject bring that up.  I can't even begin to tell you how many times
I have asked people if they have an address for so-and-so DX station
that I worked, and have been told "Why bother?  He'll just throw your
card away and keep your IRC's and you won't get squat."

    Yeah, I've had that happen.  Probably we all have, or will have
at some point.  Quite frankly, I've had MUCH better luck getting DX cards
than US ones by a LONG shot.

    Although 9Y4JL is an exception to that...don't know if he's dead,
or what, but I've tried about 5 times to get a card from him, and
sent him countless SASE with IRC's (probably about 12 IRC's by now) and
never got diddle.  Screw him.  In the meantime, I worked another 9Y4
who was very prompt and courteous so I don't NEED 9Y4JL anymore!  It just
goes to show you, Amateur Radio is a cross section of society, in that
WE get bozos too.   :-)  :-)  <<<<<note use of smileys again

At this point in the day, my brain is toast and most of what follows
will bear witness to that and to the lame condition in which I am now
typing these words. SO.....

Many years ago (as in maybe 20), there was an article in the now defunct
_Ham Radio_ magazine in which the author described an itsy-bitsy, teeny-
tiny little QRP rig that used a 350-something pf cap as a vxo tooner. The
board upon which a bunch of 1/4 watt resistors and other doo-dads was
placed was available from MFJ. I know that I am not halucinating, because
I actually had the board and put all the parts on it before I blew it
up. I'm good at blowing things up.
Anyway, does anyone remember that rig and can they think of something
in present time that is about as small. (And yes, I know about the G-QRP
clubs "Oner" boards. I think they're spiffy and if I ever regain my
sanity and health, I'll just have to put one together). I'm always game
for some teeny-tiny, itsy-bitsy, eensy-beensy little 40 meter rig that
will be smaller than the bag that carries the rig, the key, the battery,
the earphones and antenna.
Second: What is the name of the place in the States that handles the Howes
transmitter and receiver QRP kits? I have the 40 meter version, much
modified and often blown up. Now I need a schematic so that I can fix
what I blew up the last time I messed with it. It's a nice rig. I mean,
I went to a lot of effort to fit all those boards into a tiny Ten Tec
box, with a dual jackson drive on the tuning capacitor and all. Hints
will be gladly followed. Flames will be gobbled up whole. I need 'em to
blow more stuff up.
Third: I don't know about you-all, but I print my own QSLs on antique
cast iron presses. That's one cost that I can absorb with dignity. But
sending them little puppies out is breaking my bank. That's where I think
QSL burros (or is that bureaus?) come in handy. Too bad they're so
expensive. I will QSL anyone crazy enough to send me one. And upon
special occasions (like a really lively conversation over the air with
someone who knows more than the weather and the rig and the antenna and
the wattage and the time of day in China) I'll even send one out before
I get a card. After all, to me they're free. All but the postage.
Fourth: I used to QSL every contact in every contest. Seriously. I
sent my stuff to W1EP DX QSL Service and waited for the mailman to
faint. Ah, them was the days....

But I must be off. (Everyone says that I am.) There are things out there
needing a good blowing up!

No need for any ham to be without a supply of QSL cards. My cards come
from one of the hundreds of tourist shops down in Waikiki. I buy many
different postcards: sunsets, beaches, topless Hawaiian girls, sailboats
sailing on the ocean, airplane-view of the island, et cetera; only about
10 cents each. I'll write my callsign with a felt-tipped pen up in the
corner, and the QSL info on the back.

So if you are without cards find a cheap supplier of post cards, and get
a black felt pen and you're done.

Oh, I always ask the other op if he wants a G-rated or R-rated card (which
is the topless Hawaiian girl)... The general response is ``The XYL
will get mad - better send the G-rated card''.

I've grown accustomed to using those little "ear bud" stereo headphones with
my MFJ.  I'm pretty rough on these little things and, since I like to carry a
spare set, I like to pay as little as possible for them.  (This is one area
where it pays to scrimp, since the cheaper headphones generally have poorer
high frequency response, thus less hiss from the rig.)

Well, while strolling through K-Mart the other day, I struck pay dirt.  They
had a pile of Philco (Model 321K) ear buds for less than $3 a pair.  They also
included a set of replacement foam covers; all in a nice, compact little
carrying case.  I bought two pair to try and, much to my delight, they had
better volume and less hiss than the more expensive ($5 -- it's all relative)
pair I had been using.

I shoulda stocked up while I was there!

well, that was what was agreed upon by club members at the meeting
before field day (which was my first field day).  But on field
day, the more experienced CW'ers hog the rigs and didn't give
us slow-coders (20wpm and below) to use the rigs. Only hams who
can work 25-35 wpm had fun.

I believe the tiny rig Nils is thinking of from Ham Radio magazine is
the "Miniature 7-MHz Transceiver", July 1974, p. 16, article by Howard
F. Batie, W7BBX. I recognized the description and have the article in
front of me. It's a simple direct-conversion VXO rig, with a CA3028
for the mixer, and a CA3018 (transistor array) for the AF amp. The VXO
is an HEP735, and the final is a 2N3866. The VXO tuning cap is
actually not a 365-pf one, but is a 63-pf transistor radio variable
cap (the kind with thin plates with thin plastic in between, in a
plastic case). The PC board pattern given is ridiculously small, about
1-1/8"x3", and is claimed to be full-size. I always wondered about
that - it didn't seem to me that the parts would fit, and the parts
overlay is given in a larger size (1.5"x4") which looks more like
actual size.  MFJ did have the boards.

Always seemed like a really cute little rig to me.

Hello Again Everyone.

I have quite a collection of those goofy Ten*Tec Power Mites and that
brings up a few questions.  If *YOU* have, or know someone who has one of
the little devils, please check into the following...

1)  DID the Power Mite 1 *ever* include a case?  I always understood that
    the PM-1 was a simple stamped chassis, yet my PM-1 HAS side panels
    and a top panel.

2)  What do the knobs and tuning dial look like on a PM-3?  I have two of
    these (incredible, but true!) one is the PM-3A, the other is the "B"
    version.  The "B" version is supposed to just have a semi-break in
    keying feature to make it different.  MY PM-3B has the same front
    knobs as my Ten*Tec Argonaut 505.  The PM-3A has the same knobs as
    the PM-1 and PM-2.

3)  Anybody have a manual for a PM-1?  How about a PM-2B manual?  I have
    a manual for the PM-2A but don't own one of those (yet <BG>).

I'd sincerely like to hear from ANYONE else who has one of these hidden
in your closet.  I'd also like to thank the folks that have been so kind
as to forward my messages on to other PM owners.

Tom -

    South Bend, eh.  I spent four years in South Bend as a student at
Notre Dame, and have many memories there.  'course, that was back in
61-65, so it's a while ago.
    Your experience of weather on your back deck on FD was very
similar to mine.  Short, sporadic, fun, filled with rain, also sunshine,
here in Seattle.

    Do you know if Notre Dame has a ham station?  If so, do you know
if it operates HF with any regularity, and/or if it has a packet address,
and/or does it have an internet address?

Kevin -

    Sounds like your FD experience up in the tower was a blast.  Wish
I had thought of that.  You've inspired me to think of some other
locations around the Seattle area that would be fun.  Top of the Columbia
Tower?  Space Needle?  etc

    Anyhow, I see you are a Mac person.  Do you know of any software
for the Mac that is designed to handle the creation of bibliographies for
scholarly papers?  I'm looking for something.  I use MS Word, but it
doesnk't seem to have anything special for bibliographies.
    If you don't know of any, do you have a suggestion for how I
could find out?

    Many thanks. (I know this isn't qrp related, but it's a shot in
the dark.)

Hi Gang,

        I need some general feedback on the performance of the Gary Breed
kit. Please state if you are building from the Handbook, which year, or if
you are building from the A & A Kit (date). I am looking for comments and
hints or advice on the RX board for now:-

1.      Corrections, errors in schematic or PCB.
2.      Sensitivity and front-end.
3.      Crystal matching (for the filter)
4.      Mods, RIT etc etc.

        The Gary Breed I am working on now seems to be suffering from a lack
of sensitivity and the audio filter/attenuator stage is very noisy. I would
appreciate any help getting this going. Tks.

73,
daniel

I received my OHR Wattmeter kit late last week, and I tried to hastily
assemble it for FD, but it always read reflected power == forward power, so
I didn't use it FD.

The problem was extremely stupid and simple: they forgot to supply the 50
ohm terminating resistors R1 and R2 in my kit.  So, I built the rest of it,
and then when I went back, I convinced myself that there were no
instructions for R1 and R2 either, so it must have been intentional :-), so
I went ahead and wired up the switches and tested it out.  Of course, the
first instruction says to install R1 and R2, but I was in a hurry and too
hopeful!  Lack of termination of the pickup coils caused pseudo-reflected
power and incorrect forward power.

I don't have much of a parts junkbox, but I do have a computer junkbox, and
I was clever enough to realize I had some old ethernet terminators.  I
pulled them apart and used the 4 parallel 200-ohm 1/8W resistors that I
found in each terminator in place of R1 and R2.  Re-calibrated and it works
perfectly; nothing like tuning out the last milliwatt of reflected power
:-).

For grins, I tried calling CQ for a few minutes with 100mw output on 40
with my long-loop antenna, but no answer.  Band was pretty dead anyway.
Tomorrow, the 40 loop I used at FD is going up at home, and I begin work on
the QRP-NE 30/40, which I also received in the mail late last week.

No stations worked, no stations heard.

I did not receive directions to Zuni QTH through
the mail by friday, thus the no show.  Sorry guys.
It was my understanding that there would be plenty
of ops there.

BUT I did get #2 ready (albeit late again) of the
K5FO newsletter and 250 copies go out today.  #3
goes out Friday, thus getting me on schedule.  The
sacrifices I have to make.  :-)  In fact guys/girls
do you realize that I have not been on the air in
almost six to nine months?  Or it seems like it.
As soon as I find my log books I'll look it up.

On the QSL'ing.  I send out cards to all contacts
for the QRP ARCI contests and get a healthy return.
No SASE.  If I get one back, OK.  If not, OK.  I
leave it up to the individual.  I would guess about
80 percent return, but then again it may be my call.
We ought to do an experiment that everybody send out
cards for the July 10th test (I hope I can make this
one :-) ) and see how it goes.  If we start a trend
maybe it'll catch on.

I thought the 9A I worked in Georgia was incredible.  15A has to be
bizzare!  How in the world can 15 stations be managed in a 1000 ft.
circle?  I wonder what the Guinness Book of Records states for the
maximum number of stations operating in a 1000 ft. circle?

Maybe they were all QRP.  That would help.

Heck, the card I got from my first-contact-in-a-decade was just a 3x5 card
with the info written on it, and I was quite happy with it.  (Of course, 3x5
is too small for postal regulations, hence has to be sent in an envelope,
costing as much extra in postage as a postcard would cost :-).

If you're asking for a card for a reason that's likely to inundate the other
ham, making their life easier (SASE, cash, filled out card, whatever) is only
polite; but for something that's just a once-in-a-while thing (like the card
I've just sent to W1EEL), while I don't *expect* a card as a matter of right,
it's certainly not something I'd refuse if asked myself.

Well, VE3NAR (the station I accidently worked twice) grew from 9A to 10A
over Saturday night, if my copy is to be trusted (errrrrr...).

How do you fit that many stations in the ham bands?  It's one per band,
after all (well, the Novice/Tech station can double on a band).  They must
have been doing several VHF bands, for which good antennas are relatively
compact (well, compared to a 160m rhombic, anyway :-).

I just wanted to thank all of you for the product recommendations so many
of you have supplied over the past 15 months or so since the birth of this
list.  I'm beginning to realize that my station is beginning to look like
an All-Star set of products based on product reviews from this list.

Thanks Vikki (WV9K) for the enthusiastic recommendation of the Kent paddle
key last year.  Got mine a few months ago and think it's unquestionably the
best deal in keys.  A couple of other people expressed interest based on
using mine at FD.  Jeff (AC4HF) also contributed a nice review after Vikki.

Many people recommended the CMOS Superkeyer II from Idiom Press and others.
I had thought I was satisfied with a Curtiss keyer, but this really is a
nice memory keyer and has a good sending feel (especially with the Kent!).

Chuck (K5FO) has never missed a chance to tell us how wonderful the OHR
WM-1 wattmeter is; just got mine running last night, and it's already a
favorite item.  I'm ready to milliwatt!

I'm currently building the QRP-NE 30/40 transceiver.  Decided to build the
30m version because I expect the Sierra to be my 40 and 20 rig (and
eventually 80 and 160!).  By the way, NorCal people: you mentioned that
prototype band module for 160 had been made, but it wasn't on the order
form...here's one big vote for offering a 160 module!  Love the top band!

 Have built the Gary Breed (revised) transceiver from
 624 kits. You didn't say what band your rig was for.
 I built one for 17M and I find the sensitivity marginal,
 so I'm about to stick in a 10dB RF preamp to see if that
 perks it up. I put a 12dB preamp into my 20M OHR rig, and
 it made a big difference.

 As far as Pat Bunn's kits at 624 kits, I find them quite
 complete, quality parts, excellent instructions, and
 help via the telephone if you do happen to get into a
 jam. I didn't have to match crystals, and have no mods
 in mind at this point, although I believe an RIT mod was
 written up in recent QRP Quarterly.

The best I have heard of (mentioned here I beleive) was a Tektronix club
station down in Oregon with 47A -- they operated on every band from 160m up
to 48GHz.

Its not too difficult to do (assume you have two stations per band CW/SSB
and add a few more for color)

The also commented that they sent the details to QST but their photo never
got published.

Does anyone have the address to Idiom Press? I have heard about this keyer
for some time, but I have not seen any ads for it.

I have a curtis keyer already, but that may go into the NE-30-40 I am building
if the CMOS Superkeyer is as good as I hear...

A couple of corrections you can have two stations per band (one CW and one
SSB). Check the rules!

One novice and one VHF station are free (if you meet certain requirements).

And you could have 2 stations each on: 160, 80, 40, 20, 15, 10, 6, 2, 220,
440, 900, 1.3, 2.4, 5.6, 10, 24 and 47. And in infinity at > 300GHz :-)
And then there are satelite, and packet etc.

Well, I broke down and slept three hours...and I accidently had my
Seiko World Clock in Daylight Saving mode for GMT, so I accidently
quit one hour early.

Field Day 1994
QTH: Schenck Research Forest, Raleigh, NC
Power: QRP
Antennas: one multi-dipole for 80-40 and one multi-dipole for 20-25
        sailing on the shoulders of tall pines
Shelter: A tarp lean-too under the pines...plus white plastic ground
        sheet heavily sprayed with Deep Woods Off to keep
        the ticks (successfully) away.
Operated 80-40-20-15-10 CW & SSB
Class:  1B-battery-single op
Rough QSO count:    CW   220 x 2 x 5 = 2200
           SSB   132 x 1 x 5 =  660
                       ----
                       2800 points

Comments:  In recent years, I've had great success in working everything
        I could hear on 40 SSB day and night...this year it was
        a muddle with poor propagation....ditto 75 SSB at night.
        80 CW was a disappointment.

I'm a big SSB guy QRP and mobile on 40 and 75...these are the "pleasure"
bands for me.  10 SSB surprised me!! But I guess it goes along with
those who picked up 6 m and 2 m "dx" openings.  :^)

Weather: It could not have been finer!

I never worried about this before since I didn't have FTP capability; I
only get USENET (and only the rec.radio.whatever part of that) and
e-mail from the BBS I use.  However, at work we recently got full
Internet services so now I can FTP to my hearts delight (even if I do
have to pay the dollar an hour for the time I use that goes over our 6
hour daily limit).  Can someone tell me where and how to get the QRP
list archives?  Thanks.  73 and Queue Our Pea DE WA8MCQ

I recently reported winding two coils on the same piece of threaded
teflon rod, with #18 and then #32 wire, and reporting unexpected
results, ie, a slight decrease in inductance rather than the expected
increase. While discussing the experiments with one of the engineers at
work today I realized why--the coil with #32 wire was a smaller
diameter than the one with #18, even though were wound on the same
identical coil form.  I had taken the rod to the machine shop and
threaded it with a lathe--the threads are V grooves (a single groove,
actually); with a larger diameter, the #18 wire sits up farther in the
groove than the #32 and thus has a larger diameter (slightly); the #32
sits farther down toward the bottom of the groove and thus is a smaller
coil.  (I'll sit down with a wire chart some day and do the
calculations for fun.)  73 and Queue Our Pea DE WA8MCQ

Hi all,

I just got a very nice bug, chrome with red knobs in it's
nice little carrying box. Needs cleaning and some plastic
knobs replaced.

In return, I have to check out some radios for the Red Cross.
One is a TS520. I need a manual or a copy.

I relize this isn't qrp related but would appreicate any help
I can get. (Including where it would be best to post this). I
will also be needing one for a Swan and a KDK 2 mtr rig. Not
sure of the models yet.

Thanks and 73's, Ron

The Colorado QRP Club had our first FD this year in the Golden Gate Canyon
State Park n.w. of Denver.  A beautiful high meadow setting.  Our FD chairman
was a new CO resident, Paul KF7MD, formerly from the NW QRP group.  I was
told he was the best in the U.S. by Bill Todd and Bill, you were right!

Extensive planning and good equipment, antennas and operators made our first
FD a huge success.

Call:  N0BF (Big Foot)

Class:  2A  plus free VHF and packet stations

Rigs:  Ten Tec (Argosy, I think) and Kenwood TS-680S + VHF

Power:  less than 5 watts c.w. and less than 5 watts p.e.p. ssb.

Ants:  Cushcraft tri-bander on 40' alum. tower; phased verticals on 40; delta
loop on 40/15; inverted vee on 80; beams on VHF.

Power:  Deep cycle R.V. batteries and gel cels.  Solar charger.

OPs:  Total 10 ops and loggers.  6 other members attended.

Time:  24 hours with antennas set up prior to start.

WX Condx:  Fabulous.  A bit cold at night and in the 90's during the day.  No
rain!

Band Condx:  Couldn't be much better!!  6, 10, 15 were all open and QRP was
really fun.  Over 200 QSOs on 6 meters ssb and cw.

Total:  The scoring has not been completed yet, but we had approximately 930
QSOs total.  We were very pleased for our first FD.

Paul was great and Doug, W2CRS, was sure a great help with his VHF gear,
tower and h.f. tri-bander.  He was knocking them dead on 6, too.

Except for 2 vehicle problems before and after the contest, Murphy did not
strike at all.  No problems at all.  We are looking forward to FD 95.

Subject: More on the QST compact loop antenna
Reply-To: [e-mail]
Sender: [e-mail]
Precedence: bulk

A few weeks ago, I posted a lengthy review of the compact loop antenna
described in an article in the May 1994 QST. In that review, I mentioned
that Art NT1M and I built both the small (30-12m) and large (40-20m)
versions of the loop.  The small loop loaded up and worked fine on all
bands it was specified for.  The large loop loaded up and worked ok on
40m, but had a poor match on 30m, and would not resonate at all on 20m.

Both loops were taken to the Field Day setup for the Wellesley (Mass.)
Amateur Radio Society. I took this opportunity to troubleshoot the
large loop. I am happy to report that I was able to get a very good
match on 40m and 30m. The key to this was to adjust the shape of the
coupling loop. After experimenting for awhile, it became apparent that
the coupling loop needs to be as close as possible to the main loop. I
was able to do this by squashing the loop down toward the main loop.
It now looks more like a deformed oval than a circle!

I was completely unable to get the loop to tune anywhere in the 20m
band. There was not even a hint of a peak in forward power nor a
dip in reflected power. I suspect that the variable capacitor I am
using simply has too much residual capacitance and that capacitance
exceeds the amount needed to tune the loop on 20m. This theory would
seem to be verified by theoretical capacitance needed as computed by
the formula described in the Communications Quarterly article. For
example, on 40m the computed capacitance needed is about 105pF but
in reality the 100pF capacitor I have is about 75 percent closed for
40m. This would imply that the residual capacitance of my cap is
around 30pF which is more than the computed 25pF required for
resonating on 20m. Of course I could shorten the main loop so I would
need more capacitance for 20m, but then my 100pF cap probably would
not have enough capacitance for 40m!

I did not get a chance to do side-by-side comparisons at Field Day
for the loop versus any other antennas except our 20/15/10 triband
yagi at 20 feet which seems to work only slightly better than a
Cantenna. :-( I can report that the small loop worked great on 20m
CW running about 30 watts. We worked many stations all over the USA
with that setup.

I am still recovering from the lightning strike..... but tonight finally got
some info typed up about the R1, R2, and T2. I have not yet added anything
about the miniR2 because all I have is a stock of the PC boards and a hand
drawn schematic and layout. I need to get one built up before I can say much
about it. Rick does have an article in the works for the miniR2.....

I have a pretty good idea about where the pricing will be, but I need to go
over my numbers one more time before I publish the price. Look for a note
about that this weekend. It will go via e-mail to all who have sent me
e-mail expressing interest in the kits.

Barring any further lightning strikes (it is thundering outside right
now...!) I hope to build up the boards this weekend, and also get the
pricing out. What I intend to do is offer a reduced price for advance orders
that I receive for R2 kits, T2 kits, and miniR2 boards before I leave on
vacation the latter part of July. I will order the parts at that point, and
then package and ship the kits when I return around the first week of
August.

I currently have a stock of boards for the R2, T2, and miniR2. Rick is
upgrading the R1 and will have new boards available for the R1 in about 6
weeks.

Anyone who sent me an e-mail expressing interest in the kits should have
received an e-mail response - if you did not (or are just now getting
interested) - send me another note  ([e-mail]).

Here is the brief description:


R1 Module - High Performance Direct Conversion Receiver

The R1 module is a 6.5 x 9 cm (2.5 x 3.5 inch) circuit board
containing a diode ring mixer, bandpass filtering and low
distortion audio amplifier.  With an appropriate local oscillator
and input tuned circuit, it can serve as a direct conversion
receiver for frequencies between 1 and 500 MHz, or as the last
conversion stage in a superhet.  Detailed circuit description and
construction information is in August '92 QST.

Receiver

The R2 module is a 9 x 13 cm (3.5 x 5.1 inch) circuit board
containing an RF splitter, I and Q diode ring mixers, matched
bandpass diplexers and audio preamplifiers, a 90 degree audio
phase shift network, summer, bandpass filtering, and an audio
power amplifier.  With an appropriate quadrature local oscillator
and input tuned circuit, the R2 module is a single sideband or
single signal CW direct conversion receiver for any frequency
between 1 and 500 MHz.  The R2 is also an excellent last
conversion stage in a superhet system.  The wide frequency range
of the R2 board permits construction of single conversion
microwave SSB and CW receivers and up-conversion HF receivers
without the usual limitations on IF imposed by the need for
narrow band crystal filters.  Detailed circuit description and
construction information is in January '93 QST.


T2 Module - A multimode Phasing Exciter

The T2 module is a 6.5 x 9 cm (2.5 x 3.5 inch) circuit board
(same size as the R1) with a +3 dbm output multimode phasing
exciter, sine wave CW sidetone generator, and TR switching on the
circuit board.  This board will provide USB, LSB, DSB, AM, NBPM,
or CW from 25 KHz to 1000 MHz, with appropriate choice of mixer
and RF combiner.  All that is required to build a high quality
low power exciter is a +10 dbm LO and a phase shift network
operating on the desired output frequency.  The T2 board was
designed as a companion to the R1 and R2 boards to facilitate
construction of direct conversion SSB transceivers for
frequencies below 1 GHz.  Typical performance is +3 dbm USB
output with carrier and opposite sideband 40 db down and
distortion products more than 30 db down at 144 MHz.  The T2
board is described in April '93 QST.

Is there something special in the relays that are used for remote antenna
switching, or will any relay that can handle the current and voltage do?
Will the insertion of a relay in an otherwise matched system cause problems?
Enquiring minds want to know.

Ideally, you'd like a coaxial relay matched in impedence with the transmission
line. It is almost universal, however, to use ordinary relays at HF. The losses
don't amount to much.

Subject: More on the QST compact loop antenna
Date: Wednesday, June 29, 1994 3:58PM

A few weeks ago, I posted a lengthy review of the compact loop antenna
described in an article in the May 1994 QST. In that review, I mentioned
that Art NT1M and I built both the small (30-12m) and large (40-20m)
versions of the loop.  The small loop loaded up and worked fine on all
bands it was specified for.  The large loop loaded up and worked ok on
40m, but had a poor match on 30m, and would not resonate at all on 20m.

Both loops were taken to the Field Day setup for the Wellesley (Mass.)
Amateur Radio Society. I took this opportunity to troubleshoot the
large loop. I am happy to report that I was able to get a very good
match on 40m and 30m. The key to this was to adjust the shape of the
coupling loop. After experimenting for awhile, it became apparent that
the coupling loop needs to be as close as possible to the main loop. I
was able to do this by squashing the loop down toward the main loop.
It now looks more like a deformed oval than a circle!

I was completely unable to get the loop to tune anywhere in the 20m
band. There was not even a hint of a peak in forward power nor a
dip in reflected power. I suspect that the variable capacitor I am
using simply has too much residual capacitance and that capacitance
exceeds the amount needed to tune the loop on 20m. This theory would
seem to be verified by theoretical capacitance needed as computed by
the formula described in the Communications Quarterly article. For
example, on 40m the computed capacitance needed is about 105pF but
in reality the 100pF capacitor I have is about 75 percent closed for
40m. This would imply that the residual capacitance of my cap is
around 30pF which is more than the computed 25pF required for
resonating on 20m. Of course I could shorten the main loop so I would
need more capacitance for 20m, but then my 100pF cap probably would
not have enough capacitance for 40m!

I did not get a chance to do side-by-side comparisons at Field Day
for the loop versus any other antennas except our 20/15/10 triband
yagi at 20 feet which seems to work only slightly better than a
Cantenna. :-( I can report that the small loop worked great on 20m
CW running about 30 watts. We worked many stations all over the USA
with that setup.

Here's a brief report on Field Day for the Wellesley (Mass.) Amateur
Radio Society, W1TKZ...

We ran 3A and were mostly a QRO (100 watt) operation. I'm sure noone
on this list wants to hear about QRO, so I won't mention that part. :-)

I was in charge of the solar station. The setup was four 6x12 inch
panels, each providing a maximum voltage of 14.5V at somewhere between
300 and 500 ma. (I forget the exact specs) These were mounted on two
2x2 foot pieces of plywood, hinged to close like a book for transport.
The rig would be either my Argo 509 or my KH6CP QRP Three-bander, powered
directly from the panels, i.e., no batteries. The antennas our group ended
up putting up were a 40m dipole half in the trees at about 25 feet or so,
a 20/15/10 triband yagi at about the same height, and a 30-12m QST compact
loop and a 40/30m QST compact loop. I also have several resonators for my
mobile Hustler antenna system.

There were a few brief moments of strong sun on Saturday afternoon so I
fired it up on 40m SSB with the large compact loop. Nothing. Switched to
CW. Nothing. Gave up. Sunday brought steady strong sun so I settled in
with the large loop again on 40m CW. Heard a lot of signals, made a lot
of calls, came up with nothing. The triband yagi and dipole were in
pretty much constant use so I tried the small compact loop on 20m CW.
Same story: heard a lot, couldn't work anything. Tried 15m CW with the
Hustler. Still nothing. I didn't bother to try the Three-bander since
it runs even less power than the Argo. I packed it in at about 1745Z.
Oh well, it was fun anyway and I got the solar panels checked out.

Oh yeah, the loop antennas worked the best of all our antennas with
the QRO rigs. I swear that our tribander is not much better than a
dummy load, and the dipole being buried in tree branches must have
hurt its performance. Live and learn...

I've been meaning to ask whether anyone is interested in taking over
administration of the QRP mailing list.  Chuck (K5FO) put out the initial
call for the list, and I pretty much immediately assumed the list
management role; that was 16 months ago.  I'm in no hurry to get out of the
role and enjoy being of service, but it's always good to pass around
responsibility.  To do it, you should have a clue about Internet SMTP mail
and the types of bounced error messages you will receive, and you should
have the facilities to do the list.  If you're familiar with majordomo for
list management assistance, it would be very easy to move the list to a new
location; I could leave aliases at Think.COM pointing to the new home of
the list, since the [e-mail] and [e-mail] are
well-published addresses.

Statistics update: There are currently 274 addresses on the QRP list and
138 more on the QRP-Digest list.  Some of these addresses go to
redistribution points, so the actual number of people reading this stuff is
well over 400.  There has been approximately 10MB of mail to the list since
it began, and June 1994 mail alone has been well over 1MB.

GIF format is probably the most universal form, but you will need a scanner
or convertor in order to get your image into GIF.

I'd suggest posting it in EASYTRAX and GIF.  If you can't do that, substitute
that .rtl for GIF, but there will be fewer people who can use the result.
Above all, do not use JPEG.  It will blur the sharp edges one wants for PC
work.

Because of the large size of images, I suggest putting the files on FTP,
gopher, or WWW, sending only a pointer to the list.  There are a couple of
FTP sites available for radio stuff.  For gopher and WWW, I might be able
to provide space on the W8EDU WWW page.

Anyway, I think it's most helpful to use GIF and the original format.  GIF
makes it possible for just about anyone to print the image (heck, my 10 year
old Tandy CoCo can print GIFs), and the original format lets people modify
the design to fit their requirements.  ("Gee, all I need to do is to change
the spacing of these two pads...")  Furthermore, I am hereby extending an
offer to host more project material on the W8EDU page.  Just give me a holler.

Anyone have experience with the Ten Tec PTO rebuild?  I just rebuilt mine,

I did add one extra washer (3 total) to the back cup screws, since the

to avoid binding and stuff (or something like that).  Anyway, anyone good

This may be old hat, but.....  I finally built my NorCal two weeks ago
(during a bout of pneumonia) and just before a planned backpacking trip.
Funny thing, when it first went together, I included the ammeter as needed
and when I first added power, it drew 10 amps.  Fully 10 amps.  Well, I
shut down real fast, nothing warm - but found a solder bridge in the
power circuit.  After that, it powered up and worked first time.

I put together a 40 meter dipole from thin insulated wire and RG 174/U
feedline, with 20 lb test monofilament on the ends.  I wound it on a
paper towel roll.  I used a 10 AA cell battery pack (15 volts) and
the cheapo key that everyone sells.  Cheap earplugs finished it.  Put it
into a little box altogether and took it in my (now 60 + lb) backpack
with about 10 days worth of food and tent and all.  Went up into the
mountains around Big Bear (on the PCT) and had a ball with it.  Found
cooperative trees several times and hung the antenna with the stone
and fishing line method.

Setting up in the middle of nowhere with no one within many miles in
the dark of night is a thrill I won't soon forget.  I am going out for
longer next time (only a week this time) - and will hang out on 7040
again.  Had a couple of good qso's and look forward to more.

My trip culminated in the Table Mountain gathering of the Zuni Loopers,
and I am sure you all heard about N6GA FD, but I was thrilled to
death to use the Sierra there.  It is an impressive radio and I look
forward to getting one.

Well, I did what everyone seems to say we should do with our
so-called "G5RV" type antennas (the 100 foot dipole fed with
30 foot matching section followed by coax choke balun and coax....).
I took off the coax and fed the whole thing with twin lead
(cheapest Rad Shack variety).  I brought it into a 4:1 balun
right outside my shack window, and used about 4 feet of coax
to bring it into the window frame and into my tuner.

Several things:

1.  It works on 15 meters now, didn't before.
2.  My TVI has disappeared (above 20 meters even 5 w CW chopped the pics,
    but now even 100 watts doesn't hurt the picture).
3.  It seems to be happier on all bands ( 80 - 10 ), though it
    is hard to measure.  I am sure that my 60 + feet of coax
    had more loss at higher SWR's than my 300 ohm twin lead does,
    and that is the most apparent advantage.

P.S. Can anyone recommend the best articles / texts on general, very
basic antenna tuner circuits?  I would like to know about the basic
5 or 6 designs, and elementary theory of operation.  I have the ARRL

Hi gang-

Field Day Results:

Al Bates (W1XH), Randy Jones (KA9HAO) and I ran 1A from N. Kingston, RI from
a site about 50 feet from a salt water inlet.  Talk about QRP elevations-
about 10' above MSL!  Antenna height was limited to 15-20' by the
vertically-challenged nature of surrounding trees. No rain.  Steady wind kept
the mosquitos entirely at bay!

Output power was under1 watt.

80M- 8 QSOs
40M- 75 QSOs
20M- 36 QSOs
15M- 6 QSOs

All contacts on 40M were made using a "40-40"- this held up well under
contest condx.  We got a real kick out of running homebrew for Field Day,
hope to expand on this next year.  Contacts on other bands used an Argo 515.

We accomplished our primary goal: FUN!  Next year we'll work on the score.

  72-   Dave,  NN1G

The book _Reflections_ (walter Maxwell, W2DU) talks about general theory of
tuners, but really only discusses the T-match in detail.  The t-match is a
good general tuner, and can be used for coax or balanced lines (with a
balun).  At QRP, I put the balun at the input from the transmitter and run
nothing but 300 ohm twinlead. If you consider one of these, it isn't
necessary to have a split stator cap in the design.  W2DU tells why (it
doesn;t affect the performance, basically).

I also use an SPC transmatch (ARRL Handbook).  It works well, and i've used
it for coax and balanced line. It too will match darn near anything (as the
T-match does).

I'm also building a Z-match (recent issue (late 93?) of Communications
Quarterly).  Nice thing about the Z-match is that it requires no balun to run
coax, random wire or balanced feed line.  We used one at FD built by WN9V,
and it too will match darn near anything.

There was an article in (october '92?) 73 mag that detailed a t-match that
had two switched variable inductors as the top of the T and a cap as the
stem.  This is basically a low pass filter--the classic T-match is a high
pass filter.  Just another twist.

One thing to keep in mind in general, since there are usually a couple of
settings at which you'll get a match for a given load:  try to use max
capacitance and minimum inductance.  This is taken directlly from W2DU's
book, and apparently results in lower loss (lower circulating current) from
the tuner.

All in all, i've found that QRP tuners are a cinch to biuld--use BC varicaps
and torroids, if you want to.  Hook up the feedline and
go......................isn't ham radio great??

I have a Kanga (English) L.C.K transceiver for sale .. it is a
compact unit .. built on two pc boards about 6x2x4.5. It is for 80
meters. the receiver section is a superhet complete with crystal
lattice filter made with 4.608 Mhz crystals. Two NE602s are used
in the receiver.. current drain is only 15 ma 9volts.

the transmetter section uses the output from the oscillator int
the receiver. 2-3 watts. on board low pass filtering.

I think I have most of both sections built.. it has the air
variable included.. may have a couple of coils left to wind.

I purchased this from Bill Kesley for a review. so only catch is
that if you buy it..you need to finish it and write about it on
the net and let Doug publish it in the QRPp.

Kit sells for $70 without air variable... $40 shipped.

Hello all.  We started a club about a year ago, not necessarily qrp, but
ham radio in general.
My interest in ham radio was regaining after a big slump.
Well, to make a long story short, I met several (anonymous people)
that were interested in building qrp rigs as was I.

We had building sessions with qrp rigs as the basis, we copied several
designs and brought them to the club, we brought copies of Danny's catalog
etc. A lot of people were having fun. Interest by other people was sprouting
and other non qrp projects were showing up.  Everything was great..
but there were certain parties that apparantly despised the qrp stuff, and
suggested things like "we do projects that people want to do" instead of that
same old qrp stuff. When it was suggested that they come up with a group
project, they always seem to come up with an excuse not to do it.
My question is for all of you with some club experience..

1. Is it time to break off the qrp sector and go solo?

2. Is this just one of those things that is common with all clubs,
    and I should just ignore it?

3. Why are there jerks in this hobby, I thought that the 20 wpm test was
    a pretty good filter.. :-) That's a joke guys..

Dear Ann Landers,

My mother-in-law came over for a visit last night.  She couldn't have
been more rude.  She criticized everything: the house, my "wimpy old"
car, my "fat" wasteline, those "buck-toothed kids who look too much
like me", etc.  But the final straw came when she saw my new Norcal 40
QRP rig.  She took one look at it and laughed hysterically.  "My daughter's
ex-boyfriend had a Henry Radio floor model linear- he wouldn't be caught
dead on 40 with less than a killowatt.  He could beat the living bejeezus
out of you.  I wish she had married him."  Later that night, she was in
the bathtub, and asked me to hand her the shampoo.  Instead, I handed
her a 50-amp power supply.  She's dead now, and I'm worried that
I did something illegal or something.   Did I do the right thing?

all,

I think the LCK is sold.

I have a Yaesu 301S older, super good condition transceiver that
does CW, SSB, FSK and AM (even CB). It works great on SSB and puts
out to about 12 watts. it works great off a gel cell .. thinking
about selling it for $300+shipping.

Also have a Century 21also have a Century good condition, new
finals. sell for $150 +shipping.

look for other stuff in the near future.

Hi Jeff,

I'll take it if no one else has spoken for it.

For those who havn't tried 80m qrp it's a blast. But
then all cw is a blast!

Let me know and I'll send the address.

Dear QRPieved,

Once in a while I have to put up with something at work that I don't
like. Even a jerk now and then.

But with my hobbies, I refuse to get upset. I do what I like and
let the others do what they like.

IMHO clubs should be the same. If you don't have a common goal for
the group and if people won't work towards that goal it will never
be fun. So I would suggest at least sub-groups.

If there are people there that really keep all the rest upset, take
a vote and maybe ask that person to leave.

But remember FUN. If it's no fun, change it. Keep doing that till
it is fun. (Don't forget that fun to some is keeping others up in
arms!).

Just my 2 cents worth from a very PC soul.....

73's, Ron

Oh for heaven's sake.  If one can't make fun of the PC movement because one
fears complaints from *both* the foaming PC zealots and the frothing anti-PC
zealots, it is truly a sad day indeed.

You might check if the PC has a spelling checker.

Some requirements:

- MS-DOS and preferably Windows compatible.
- Inexpensive (will be used for personal / ham radio

- Autorouting not necessary; manual routing with a mouse
  will do.
- Single-layer PCB only is OK.

Thanks to everybody who replied!
There were some really good suggestions... that sounded an awful lot like
my wife's suggestions.....

To be honest, this is a real situation, but I thought it might be good to
get to the
lighter side of QRP on a day before the holiday.
73 to everybody and have a safe and fun 4th of july..
and to the other countries listening besides the U.S., have a great weekend!
Brad WB8YGG


P.S. I might try qrp portable from The homeland (michigan) on the 5th, 6th and
or 7th sometime around 9:00 pm EDT, 7.040 or so.. Maybe I'll hear some of
you.

Just before FD I picked up a solar panel from the American Science and
surplus here in Milwaukee. It was a 21v unloaded, 12V@892 ma panel in a
glass and aluminum frame. It was orignally designed for topping off batteries
for RV's I guess. They claimed it was new and it looked it. We ran it for our
FD natural power contacts with an Hw-8...no battery.  It cost me $99.95....Was
it a good bad or average deal? Too late now. They had several left.

They also had several other types of panels there at lower ratings that cost
more and didn't look as nice.

73,

I am in the last stages of getting my next Kanga catalog out. It has a list
of QRP Clubs in it - and I need the address and membership info for the St.
Louis and the Oklahoma QRP clubs to add to the list. There must be someone
on the list that can e-mail that info to me.....

I have the following clubs already:
ARCI
G-QRP
Nor-Cal
Michigan
CW Operators QRP Club (Australia)
QRP Club of New England
U-QRP Club  (Russia)
OK QRP Club
K5FO's QRP Newsletter
Northwest QRP Club (could someone confirm this one as
N7MFB 2418 55th etc)

Are there any others I have missed??

When I get the info I will post it to the list.

Perhaps this is the start of a FAQ??

   These are the same amorphous 'big' panels available from several
sources in Nuts & Volts for about $25 plus shipping.  The amorphous
cells lose some capacity with time - I recall it to be about 20%.
Not, in general, a good deal, but better than no power source at all.
   I have one of the smaller ones in the window in the Dead Radio Room
to keep the 12V regulated power supply charged.  Its big advantage?
It fits in the window, and won't overcharge the battery too much.

Finally worked my first member of this list:  VE3VAW on 40 meters, 6/30/94
(UTC), 0229Z.  My 8 watt homebrew got me a 559 report.

That was the best of a string of real discouraging QSO's under awful band
conditions.  I was using my new compact transmitter on the air from the back
patio, testing out a 40m delta loop thrown into the trees.  After poor reports
for a few QSO's, I came in out of the Minnesota mosquitoes and operated the big
rigs (boo!).

But the night of 7/1/94 UTC things were much better; back to QRP, and a nice
string of QSO's to NJ, MI, AL, NC, GA (inside, using my 80m horizontal loop)
with reports ranging from 569 down to 339 (but that only as the band faded out).


Just gotta keep the faith, folks; it can only get better, and even now some
little shining spots of decent propagation pop out.

Can you track this down further?  My current dilemma is coming up with ONE
design that really works for either balanced or unbalanced.  For example, my
balanced version of W1FB's "Simple Resonant ATU" has the link wound in the
middle; this is less than optimum for unbalanced....

QRP Classics gives us "A Simple Resonant ATU" (I made a cobbled-up balanced
version), and "A QRP Transmatch for Balanced Lines" (a variant of one of my
favorite designs)

My favorite:  Feb. 1990 QST, page 28ff details "A *Balanced* Balanced Antenna
Tuner".

Basic premise:  Most commercial tuners put a 4:1 toroid
transmission-line transformer on the output and call that suitable for
balanced lines.  This is nuts, because they don't perform under
reactive, unmatched conditions (the usual situation in tuned lines) and
aren't balanced to give equal *current* in both legs under all
circumstances. You need equal *currents*, not *voltages*, in a balanced
line to keep it from radiating.

Solution:  put your balun on the INPUT -- a choke balun of coiled coax
is cheap, ugly, but very effective.  Can also use ferrite sleeve balun,
like the W2AU. And, use a balanced L network, where you split the
series elements in both legs of the balanced line.

My version:

                       ____UUUUUUU_______________<
                      / Roller inductor 1  |
                     /                     |
    Coax choke balun<             Var. cap.=      Bal. ant.
  20' RG58           \                     |
    on 5" form        \_ __UUUUUUU_________|____ <
                        Roller inductor 2
                        (mechanically linked to #1)

Little RF in shack since I put this in!

Your balun could also be a ferrite sleeve balun, or a 1:1 CONVENTIONAL
transformer of adequate power rating.
