Subject: Surplus QRP Gear (GRC-109)

Well, I got my GRC-109 rig on the air today. It's a pretty
neat collection of boxes. Considering it works on 80-15
meters, including all points in between, it's not a bad
deal at $120, which includes a copy of the manual (they
don't give anything away at Fair Radio Sales). You need
FT-243 crystals for the transmitter.

In case you're interested, here's some information I
obtained today:

FREQ        POWER OUT (WATTS, MAX)

3560        10
7040        15
14060        15 (no 30-meter crystals)
21060        12 (no 17-meter crystals)

The open-circuit keying voltage is +60. The rig is cathode
keyed; off-resonance keying current is 125 mA, 100 mA at
resonance.

The weak link is the receiver. While sensitive, the tuning
rate is quite fast and it has 9-kHz selectivity. An audio
filter will help some, I'm sure, but that's still a lot of
signals in the passband. I may splice a ceramic filter in
there, 4-kHz bandwidth or so. The good news is, it has
provision for crystal control also, so you could arrange
an external VFO for the receiver (F + or - 455 kHz).

On the other hand, I was able to work W2FO in New Jersey
on the coax running up to the W1INF beam, on 40 meters, and
hold the frequency for as long as I could send on the built-in
straight key: about 20 minutes.

Antenna and headphone connections are via spring-loaded binding
posts (jacks would be hard to waterproof I guess). I am using
old electromagnet headphones (hi-Z); I rigged up an SO-239 on a
piece of zip cord for the transmitter output. You can run full
QSK, but, even though the key shorts the rcv antenna when
transmitting (!), it's noisy. Hard to find your frequency, as
the rcvr overloads. I had to back off the drive. They should
have included a spotting switch.

There's NO AGC in the receiver. The BFO runs continuously. It's
output is sampled and rectified to provide a gain-control voltage
for the receiver! When you want to listen to R Habana (to see if
your clandestine operation has been detected), you just turn the
BFO control to the OFF area marked on the panel. That raises the
BFO frequency above the range of hearing.

Okay, so it isn't an HW-9. You could probably throw these things
out of a plane at 500 feet without a parachute and they'd survive.
You tune up the transmitter (Remember those days? You're probably
eligible for QCWA) by peaking two neon bulbs and a #47 lamp
arranged as an antenna ammeter! SWR? What's that. The book says
it will match 72 to 1200 ohms. I noticed the loading cap is fully
open when looking into 50 ohms. Especially on 80 meters, I got
the feeling I could squeeze more power out if I could match the
lower impedance.

Yes, it will drive random-length wires--it was designed to use a
75-100 inverted L. There may be a problem with harmonic suppression
when you use a random wire. There may be a problem with harmonic
suppression when you use a 50-ohm load. Am I going to put this
thing on the spectrum analyzer? Hmmm. On 80 and 40, my operation
will result in harmonics falling on the ham bands. On 30 and
up.... I think I'll run it through a Johnson Matchbox--they take
harmonics down pretty well.

There's a hand-cranked generator out there for this thing, but
I'm not sure I want to use it on FD. It could be useful for
aerobic exercise, though.

If you have any questions, feel free to send email to me. If
you put one of these sets on the air, I'd like to work you. Just
give me time to rig up my keyer!

72,

Jim, KR1S

Is there anybody out there, who could give me some infos:

1. 2 years ago an OM was in Dayton and saw a kit which emulated a frequency analyzer when switched before a scope. He does not remember name of the company nor details. So if someone knows anything about it or has actually used it I would be glad to know.

2. Just read in the QRP Quarterly about a kit from Smith Electronics - (Fireball). I couldnt find the  oscillator in DL and there were some remarks from the editor.

Is it still available and worth the price - and of course the trouble ordering it in USA :-).

Subject: home-brew dxcc

   I think I've mentioned before to this group that one of my current ham
interests is 30 meter qrp dx, and that I'm soon planning some decent antennas
for that purpose.
   I've been thinking about all the hassles involved with getting qsl cards,
verifying them, and sending them off for evaluation...plus the fact that dxcc
is not available on 30 meters anyway. I finally decided I like communicating by
radio, not by post card, so I will NOT make a big deal of getting qsl
confirmation. Instead, for my personal record keeping I'll count all qso's in
my log that include an exchange of calls and rst's, and when my count gets to
50 countries, I'll use my word processor to make a nice certificate to hang on
my wall...and every additional 50 countries thereafter. And I'll announce my
progress here periodically.
   For me this will be as satisfactory a way of marking and celebrating the
meeting of the qrp dx challange as any.
   Wonder if anybody else approaches DX this way?

Cheers & 73!
Jim   K5YUT
(P.S. Incidentally, the above does not mean I don't enjoy getting qsl cards, or
that I won't send them...I'm glad to, if someone wants them. It's just that I
don't want to turn my hobby into one of collecting cards!)

In "The Complete DXer," Bob Locher says DXing is what you make of it.
You set your own goals, etc. After a couple of frantic years in the
pileups and a book of my own, I, too, got tired of chasing the paper.
I quit about two years ago, as I recall working Baldur when he was
in Mt Athos, right after returning from Dayton in 1991. I never wrote
for the card. I've even stopped chasing DX, outside of contests. If
you tell me you have the cards for the Honor Roll, but haven't turned
them in, I'll believe you (and the DXCC desk will thank you!).

We don't have to let others' goals determine our own. This is, after
all, a hobby!

72,

Jim, KR1S

In the office having a ball cannibalizing some old junk for parts to
build a power supply for the GRC-9, which is the next surplus acquisition.

And what about a Usenet QRP QSO Party? No scoring, etc, just get on
and say "hi." The exchange could be the usual stuff, but USE instead
of RST, or something like that. WATSA OMS ES YLS?

I haven't used it, but A&A has a 450 MHz Spectrum Analyzer that uses
a scope for display.  it is $460 as a kit or $800 assembled.  a 230v, 50
Hz power supply is avail for $5.  they warn that this is not a kit
for the novice  & you need a freq cntr & rf source to calibrate.

Well I've got about 173/157 mixed from this QTH and keep telling myself
I'll get around to applying for the certificate when I get the few cards I
need for ssb dxcc. But then maybe I won't but I'm still having fun. On a
related note, if I recall correctly there was some discussion of requiring
qsls for awards in QQ recently.

There have not been reports of iron powder toroids being damaged
by excessive heat, though they won't function properly if they get
too hot (but will if they get to cool back down).  This also assumes
that they didn't break into little pieces.

I assume you are properly packaging this transmitter and grounding
the chassis.  Unfortunately, this design may not be well behaved in the
presence of RF fields due to its use of high impedance/gain circuits.

Hi,

For the less fortunate of us who got stuck at work this
weekend:

    1. any new rigs out (Icom HF?)
    2. Ten Tec QRP (anyone touch the new one?)
    3. Ramsey 20 meter CW/SSB? (is it going to be in kit?)


thanks

No new Icom HF rig.

Yes, there was a new Ten Tec rig -- the Scout 555, at $495 for the radio
plus one band module. Add'l band modules are $25 each. 50 watts output
CW/SSB. Optional noise blanker (no price). Shipping in July.

Ramsey 20m rig as a kit was $299.00 Lots of $$ as far as I was concerned.

Eric,

Are the Scout 555 band modules really only $25 each?
That seems too cheap. I think a previous message listed
them at $225.

(And... thanks, Harry!)

----- Begin Included Message -----

   I took a look at the Scout spec sheet when I got home.  TenTec says
there's an internal adjustment to reduce power.  As to how low the power
can be adjusted, TenTec does not say directly.  However, current
requirements are specified for 50 watts out and 5 watts, so I presume
the power can be reduced to 5 watts.

Nope, but it looks like it would be an internal setting. No drive control
on the case.

Subject: QQ April 1993  Volume XXXI  nr 2


just got the quarterly today.

there are no contest results at all anywhere for the qso party.
looks like there will be a significant change in the board of directors
and officers of the club.  Paula, WB9TBU, will not be running for
re-election for president and Luke, W5HKA, also is not running for
re-election as secretary-treasurer.  three directors terms will expire
at the end of the year.

New World Miles-Per-Watt Record with the Fireball: 2.133 billion.

Bob, K7IRK, and Bill, WB8ELK, from Palestine, TX to Hancock, NH,
using 0.72 microwatts for a distance of 1,536 miles  1/19/92 at
2133UTC on ten meters.

for those of you who might not know, the Fireball is a kit sold by
Smith Enterprises in CA for $26 including shipping.  uses a computer
oscillator, max of 50 milliwatts (DigiKey CTX128 or X131) on 28.322
or 28.060 MHz.  just key the B+ at 5 volts to 6 volts max.  feed
output to antenna via 0.01 microfarad cap.  hope you got some filtering
in the tuner!!!  ;-)  K7IRK, designer of the circuit has worked
WAS with 2 milliwatts.

that's it from here.

Absolutely!!! If you don't go to Dayton and get rained on in April,
the whole year is just shot!!!

Personally, I brought home every Heathkit single bander that I could

Subject: Dayton

I'm back from Dayton, and I believe I've caught up on all the QRP-Request
messages.

My major purchase at Dayton was solar power equipment: I bought a 38W solar
panel and enough batteries to keep a QRP station happy for quite a while
(four new 24Ah gel cells for $50).  Field Day, here I come!

I'll build a charge controller.  There have been a number of them published
lately; if anyone has opinions on the best setup, let me know.  I did buy a
Tejas $19 low-current (.7A) charge controller kit which I may just beef up
for several Amps.

I didn't get a chance hang out with the QRP groups there, but I did join
QRP-ARCI and G-QRP.

Why wait til June??? East Coast QRP/Usenetters: 7030-7040,
1200-1400 UTC this Sunday, May 2. If I have to start the
QSO Party I will! Exchange: USE (instead of RST), name,
state, power. Then, whatever else you feel like talking
about. No power limits, no logs, no score, no multipliers.
We can compare notes here next week. If you're reading this
group, I know you'll run the minimum power necessary anyway.
I'll be trying out my "new" GRC-109, crystal controlled on
7030, 7035 and 7040 (haven't finished the VFO, yet).

Call CQ USE. That oughta rattle the OTs!

If OK1CZ of the OK QRP Club is still with me, I'll let him
operate. If my station gives a name of Petr, you've gotten
the Czech (sorry).

Actually, to be a REAL QRPer, you must make a contact with the circuit as
wired.  (Distance is not a criteria, so if all else fails you may throw it
at another ham to initiate the QSO.)

Hello QRPers,

Since I'll be going to the Rochester, NY Hamfest in

wondering if the converted SSB cb xcvers are any good
for cw and if so what's a good price?

In the UK there is a design/kit from the White Rose ARC which was
originall published in RadComm.  I think its a single band phasing SSB
TX RX, based around a series of plug in boards. More current British
hams may be able to supply details of this rig. I note that mods and
add ons appeared for it in a recent SPRAT.

There is also the Rn and Tn series of receivers and transeiver designed
by Rick Cambell KK7B have been appearing over the last year in QST. A
down side though I have heard of people having problems getting the
kits or pcbs out of him :-(  These are excellent designs -- see June
1992 and March and April 1993.

Hello Brad:

You mention the desire for a SSB QRP transceiver kit....and you echo
the desires of many (but not enough to move the "free market"?)
I would welcome a kit like this, and I have heard some discuss
that MFJ plans such a kit (?), but do not know for sure.  There is
a 20 meter SSB transceiver in the Handbook, but it does not look like
a beginner's project (though I haven't tried building one, so I do
not know for sure!)

As far as 5 watts of SSB, I work SSB QRP more regularly than I do CW.
I do most of my work on 40 meters, and have had tremendous success
during good conditions.  I can even go mobile QRP SSB (ham stick
antenna) and be heard a lot of the time.  You are exactly correct,
during good conditions, 5 watts is just great.....and less power
can still do the job!  I have been called a "liar" on more than one
occasion during a ragchew on 40 m SSB because I was consistently
above "S9".  It's a double edged insult!  God bless my little Argonaut,
it has given me a lot of interesting times.

RS12/13 has an uplink on 15M and a downlink on 10 M. I thought it might be
fun to try to listen to the beacon until I could get a QRP xmtr together for
15M. When I uploaded a file with the latest Keps, RS 10/11 was the only one

Thanks for the information, Bruce...

I ftp'ed the latest keps from archive.afit.as.mil and looked in the /pub/space

I checked the file of keps and have Cosmos 2123 listed.

Thanks for the quick reply.

To reply to Bob's question, QQ stands for "QRP Quarterly" which is the
the quarterly publication of QRP ARCI. This is an excellent source of
information for QRP enthusiasts which has a little bit of everything...
product reviews, home projects, contest, awards, exchange of ideas.
QRP ARCI is the international organization of QRP enthusiasts whose members
are interested in all areas related to low power operation.

I have the membership information at home and can send it to you.

Subject: MXM Rig


Gang,

Jeff, AC4HF, i think i have the call right.  asked about the new
MXM rig, so in order to save time i'll give you a quick update and
then a final review when i get it assembled.

first:  it's a transceiver, single band
second: board is 4 1/2" x 3 5/8"  (11.2cm x 9.2cm)
third:  uses the superRX receiver and transmitter from WA6IVC (Bruce)

nice board with silkscreen.  it's not green, but it goes inside a
case anyway.  ;-)

the kit is not out yet, but will be shortly.  i'll let you know.
Bruce will be showing the rig at the Hamcom fest in June here in dallas
area.

the rig is vfo controlled, thus eliminating the previous problem of
being crystal controlled.  will work the whole band.  can be set up for
80, 40, 30, and 20 meters.  don't know if other bands are gonna be
available for any time soon.

kit doesn't come with cabinet and additional hardware (key jacks,
power plug, etc.).  this may be a turnoff for some people but not
for the real hackers.  :-)

i'll shoot for getting it built this weekend or middle of next week.

output transistor is 2SC799 and should be capable of 5 watts out.
may run hot, but hey, silicon doesn't melt until the temp gets real
high......

72 de k5fo   chuck     dit      dit


p.s. rig to sell for $99.50 or so.  definitely the hotest receiver around.
     500 Hz bandwith with possibility of going down to 200 Hz bandwidth,
     but you'll probably get some 'ringing' at 200 to 100 Hz.  uses Cohn
     filter in the IF.

more details to follow.


ciao,

chuck

Rod Newkirk tells a story of a ham who finished slipping together

into a tree to get height for the end fed wire. It wasn't until he

Subject: Re:  VFO Phase Noise

Choosing the right core material:

One good point made by Mike Czuhajewski, WA8CMQ, in the current QQ (and
I think Zack Lau KH6CP made this comment in QST  tech correspondence
too) is to use -7 (white) cores rather than -6 (yellow) cores.

The -7 has a temperature coefficient of 30 ppm compare to the -6 35ppm
(not much but it is 20% less!). Avoid -2 (red) cores with a temperature
coeff of 95ppm.

Most NP0 capacitor have a temp coeff of 0 plus/minus 30ppm so you still
made need a little fiddling to get that ultimate stability!

He suggests using it as the VFO standard, especially as Amidon now
stock -7 toroids in T37, T44, T50 and T68 sizes.

OHR are using these cores in their kits.

Subject: Re:  VFO Phase Noise
Date: Friday, April 30, 1993 3:37PM

The referenced VFO circuit has excellent (low) phase noise characteristics.
This is mainly attributed to using a high Q tank circuit (high C, low L and
L wound on a fairly large torid, T-68-6). The high Q is maintained because the
coupling to the rest of the circuitry can be made very light (3pF typical)
because its not critical for supplying feedback. Using 1Meg (vs 100K) for the
gate bias resistor helps too. This Hartley circuit is one of the lowest noise
oscillators you can build.

For example, when used with a DC receiver, you can actually hear a difference
when using this circuit (weak signal reception and tonal quality)

Its also one of the most simple bullet proof VFO circuits to build and offers
a lot of flexibility (e.g. easiest to temperature compensate, get a desired
tuning range with on hand variable capacitor etc.).

Subject: Re:  Campbell KK7B R1 DC receiver
Cc: [e-mail]

Yes, I have built one. Also made many modifications to improve it. Its one of
the better DC receivers I've built. Does have excellent DR, low noise and
its the only DC receiver I've heard that actually has the tonal quality that
everyone talks about.  The filtering is really nice. A summary of the chages
are:

1. Elimated L2 and R2 from the diplexer to improve AM suppression (I live near
   an AM broadcaster). Also lowered all the high pass filter corner frequencies
   because I like to copy a lower beat note than 750Hz. As shown, there all
   above 300Hz, which is fine for SSB.

2. Rebiased the 50 ohm audio preamp for proper operation with a 13.5V supply.
   Also used a ultra low noise transistor at Q1.

3. Improved the 7th order eliptical filter. Author scaled values from another
   authors SSB design. Tightened up the filter quite a bit. See attached.

4. Improved the biasing and changed the gain distribution a bit on both U2A
   and U2B.

5. The power amp had a Icq of 100ma and gets quite hot. Don't need to generate
   this kind of heat and use this much power. Rebiased the power amp to idle
   much lower (10 -20 ma). Fidelity is still excellent.

Edward,
You mentioned that you replaced Q1 with a very low noise
transister. Did you notice any change in noise level with the change? In
Rick's article, he mentions that he found the noise to be ~5db worse
then he expected because of 1/f noise generated in the mixer diodes in the
SBL-1. Is that the major noise source? also, what transister did you
use?

Jim, the harmonics are *terible* on those rigs!  To be FCC legal below 5
watts, the spurious emissions must be more than 30 db down, ond on
square-wave oscillators they are usually about 6 db down.

If the tuner used is a pi-network, that provides some more attenuation.
True, the absolute level of the harmonics is low, but to be perfectly legal
they need a lot more filtering.  A simple 5 or 7 pole Chebychev low-pass
filter should do the trick nicely.

I suspect, however, since the actual harmonics are at a low level that the
FCC most likely won't be out to bother anybody using such a rig.

Hmmmmm.

I tried a little on Sunday morning with my HW-8.
I tuned for about half an hour and I called CQ USE for about half an hour.

I tried on and off for 2 hours.. the bands weren't feeling
very well.

I would really like to do this and get to meet some of the
Usenet people on the air.

I hope we try it again (would really prefer an hour later..
7:00 am is very early for Sunday.. only morning I get to
sleep past 6:00.

Hi,

The Amatuer Club I belong to the Superstition Amatuer Radio Club (SARC). We have a
friend that is a missionary in Bucharest Romania.  He has met many of the students
in the EE dept. at the University there.  We, SARC, are putting together a care
package so to speak, with old HAM magazines, books etc. This is to help their
radio club to get started.  The reason I am posting this to the QRP
group is to get your recomendations for a Xcvr Kit to send over.  We are going to
to need a kit that is 12V DC as the Electricity there is only on for 4-5 hours
a day (sometimes less) and they currently use batteries for most things due
to the power problems.  Any help would be appreciated.

They have tried to scrounge parts for a radio, however the neccesary parts/equipment
are very difficult to find, as documentation for home-brewing with the electronics
they can find is non-existant.

Thanks again.

To add to what Jim/WD9EYB mentioned:
    I heard a  lot of stations between 7030-7040 at 1200Z- 1400Z but
couldn`t tell who was part of the USE group.  I didn`t hear any CQ USE. Maybe
in addition to calling CQ USE any time you give your call sign durning a QSO
put a /USE after it. Anyway I made 3-4 long ragchewing QRP QSO`s with non USE
stations and added a couple more states toward getting WAS/QRP award. Try to
connect next sunday I`ll be around 7040.

Nobody seems to have worked anyone else from this group!
Two people have indicated interest in doing it again....

The LUF goes up fast now that we're into warmer weather.
The best times on 40 are a whole lot earlier than 1200Z,
at least on the East Coast. Let me have a look at the
propagation tables...but maybe the fall would be a better
time for a nationwide event. There's also the QRP ARCI first
Sundays, which start next month. Hope to meet some of you
then.

   I've been noticing that many of you are signing your email with the
salutation "72".  What is the meaning and origin of 72?  Do folks
running 10 KW commercial HF amps sign 74? :-)

I'm posting this index for Doug KI6DS who wants to make it available
to the QRP group on the Internet.  Doug can be reached at:
[e-mail]
All the standard disclaimers apply.  I have no financial interest in
this list nor the back issues that Doug is making available.
(I understand that the back issues are made available at cost)
Doug is looking for the following issues of the QQ:  October 87, January 88
and April 88.  If you have any extra copies of these issues of QQ
contact Doug at the address above.

Preface:  This index was done by KI6DS, Doug, who makes it available to all
QRPers.  Hopefully you will find it useful and handy as I have.  I suggest
that you put it in your word processor and use the search feature to find
keywords.  The categories are rather broad, but necessarily so.  I will do
updates each year and make them available.  If you would like to have
reprints of back issues, I have them available for $10 per year, plus $3
postage per order.  I have the years 1985 - 1992.  If you order all 8 years,
there is a special price of $73.  Each year is bound in 1 book, so please do
not ask for individual issues, i.e. April 88, as I cannot make them available
that way.  Please feel free to distribute this to anyone as long as it is not
used in any way to make money.

Making this list a newsgroup would be a disaster (witness all the other

would drop like a rock.

The throughput of this group is miniscule compared to others. Skim
reading and use of the delete command are recommened.

Finaly if you wish to unsubscribe send mail to qrp-request and NOT THE

If there is an informal discussion or vote going on, I prefer to
leave the QRP mailing list just like it is.  I am not in favor of
a newsgroup because of the threat of a higher signal/noise ratio.
I am very content with the volume and the personal nature of our
list.

I certainly don't mind initiating a news group, but don't feel overwhelmed with
mail from this alias, either. If I want to review subject lines and read
selectively a quick "dir" followed by a judicious "del" does the trick. (Of
course I don't have to pay for disk space, either!)

Hi,

I agree with Clark.. I think low power people are special
and this is a chance to get to know each other a little
better.

I really look forward to USE QSO parties and such. I tried
to get on the air and catch Chuck Adams last night, but
unfortunately we had a tornado watch and very severe
thunderstorms and such.. I decided to wait for another day
(although I admitt I did have the rig on for a little while
till the lightning was right overhead).


I think that the photo album is a great idea.. neat to see
what some of the other weird QRPers look like.. I think
Chuck is looking for a few more projects..HI HI

As I've stated before, I have no intention of making the QRP list into a
newsgroup anytime soon, for many of the reasons cited by others.  The list
is a manageable size (about 130 recipients right now in 12 DXCC countries).
We lose a few people every so often because of heavy volume, but I've been
pleased with the amount of information and discussion on the list so far,
and it's inevitable that the volume of a successful list will drive some
people away.  But let's not spend our bandwidth discussing list vs
newsgroup, let's spend it talking QRP.

The current list of things in the anonymous FTP area (on Think.COM, in
directory pub/radio/ham/qrp):

 1675 Apr 15 12:44 clubs        List of club membership info

 2607 Apr 13 15:53 qrp-ne.info        Membership form for QRP New England Club

Jim Kearman, KR1S, has volunteered to maintain a list of Frequently Asked
Questions for the group.  Suggestions for that should go to him
([e-mail]).

I, for one, completely forgot about the Sunday morning QSO party.  Sigh.

Subject: Field Day / Solar+Battery

Apologies to those also on the CQ-CONTEST list, where this was already
discussed, but it's relevant here, too.  Apologies also to the DX on the
list, who probably don't care about this subject!

I've been getting ready to do Field Day using Solar+Battery power, which
I've never done before.  So, I read the rules, and found a surprise (at
least to me).  The "Battery" category applies to any power source other
than commercial mains or motor-driven generator (batteries, solar, wind
generator, ...).  However, there is a rule in the scoring section which
says that except for Class C mobile operation, batteries may not be charged
while in use.

This implies that it's not within the battery category rules to have a
solar panel providing power to a battery while operating from the battery,
even though operation direct from battery or direct from solar panel is OK
for that category.  Floating a solar panel across a battery is the "obvious
thing" with that set of equipment, especially if you only wanted to use one
battery.  I thought the rule was silly.

After talking with a few people, the consensus was that the rules meant to
say you can't use a motor-driven generator to charge a battery while it's
in use.  That makes sense, since it disallows using a power source not
allowed in the battery category while operating off the battery.  Anyway, I
guess it comes down to the spirit or the letter of the law.  There's also a
reasonably easy workaround: you can operate off of one battery while
charging another with the panel.

I disagree - this group is acting like a moderated usenet group.  Those
have very good SNR (eg. I get much more out of 5 minutes with
rec.radio.info (moderated) than I ever got out of 30 minutes with
rec.radio.amateur.misc (flamefest).

Newreaders offer much more control over reading articles (eg. they follow
threads, they allow jumping around inside the longer articles, they
automate much of the reply or followup process).  My mail reader doesn't
have these features.

One of the appealing aspects of QRP is the rabid fervor
of other QRPers. You don't meet too many QRPers who are
lukewarm about using low power, building equipment,
operating Field Day, or whatever particular areas meet
their fancy.

There _has_ been a lot of mail on the list, but I think
that's largely because it's new and we're just getting
acquainted. If you're a died-in-the-wool QRPer, you'll
read through it all, unless receiving it causes a
financial hardship.

One thing I've learned as a reader, writer and editor of
material about QRP is, we've said about all there is to
say on the subject! That's not to say that additional
articles aren't needed to inspire newcomers, but there
really are a ton of books out there. ARRL alone publishes
five books that have to do with QRP. Then there are books
by Dave Ingram and Rich Arland, G-QRP, and Adrian Weiss.
I receive five QRP club newsletters.....

I see this list developing into a place to get info on
parts, to buy and sell gear, and to arrange operating events.
I think in a short time, the mail volume will drop quite a
bit. I don't know how many readers we have, but I doubt we
have enough to warrant another rec.radio.amateur group. I
suggest we keep the list as is for the time being. In six
months, if mail volume remains high (which I doubt will be the
case), we can then consider other alternatives.

Personally, I like the content and volume of mail I get from this list.  I
know alot more about QRP and QRPers as a result.

Perhaps *copying* this mail to a newsgroup would satisfy the needs of those

Myself and friends have just used either regular AA or C cells (lighter
than gel cells for backbacking) either soldered together by the tags
(10 x is 12V) or used the AA cell holders (x 8) from Radio Shack and
similar outlets.

If you find a x10 AA or C cell holder let me know.

Regarding gel cells my two surplus 7AH cells are just too heavy to
carry! I have my eye on a Quantum Ham battery as permanent solution. I
have played with one and it looks like a good backpacking battery: not
too heavy but with good capacity and charger/monitoring built in. Jeff,
AC4HF, do you have one of these?

Hi,
does anyone know of a good source for rechargeable batteries? I was looking
for a 12v or 9v 2Ah NiCad battery to use for a QRP rig and a HT.

I am currently using Makita Batteries ( the kind used in rechargeable
drills etc.)  They are around 10 V (although 12V is available) have a
large capacity to weight (my gut feel)  they are cheap and recharge in 1 hour.
I started using them because I had a drill with these batteries and decided
that since I had a charger and a battery I would play around with it.  I have
yet to use the HT enough on a weekend to drain one of these, however I don't
talk much.  I have also run mobile rigs @ 5W off one of the batteries, I am
currently looking for a SIMPLE circuit to take 2 of these batteries at approx
10V and regulate it down to 13.8.

The cost of these batteries is on the order of $25  if I remember correctly,
and you might even have one or two hady for experimenting with.

I went through the directory file last night and didn't see any
Mizuho/AEA QRP rigs listed. Is there anyone besides me that is using
the A.E.A Mx-28S (or other models for other bands) ?? I am interested
in any possible mods or enhancements to these rigs.

I found one guy over on Compu$erve that collects the Mizuho rdios and
owns over 20 of them. Must have cost him a bundle. I bought mine on
sale ($160 delivered via UPS Red label) from an outfit in Canada. I
would be glad to offer the particulars if anyone is interested.

I am also looking for a good antenna design for the 10 Meter band. I
tried building one of those twinlead dipoles described in the Antenna
Handbook; but the SWR is really high and I can't seem to figure out
why. The dipole is the correct length and it resonates on the desired
Freq., but the SWR remains way too high. Any ideas? Perhaps the
shorting bars across the dipole elements need moving? or the
capacitor in the feedline needs to be a different value? I have
tested it between 26 and 32 MHZ and cant find a spot were the SWR
drops to below 3:1

Don:

One thing you should look at are the new simple high efficiency
switching regulator chips from groups like Linear Technologies (and
others). The great thing about them is that they have efficiencies of
order 90% or better and cope with wide variation on the input voltage.
Some will source up to 0.5A too!

These have almost arrived at the point of being as simple as an LM317
regulator. This is great for field use. So long as you can keep any RFI
down from these devices it seems that they should have some good
application in QRP.

The reason they've developed these devices is the burgeoning market for
longer battery life in portable PCs powered by nicads.

Check out EDN and you local supplier. Can anyone who's been following
the literature more closely provide device numbers?

Why not a simple 52-ohm coax fed dipole, horizontal or vertical? Or, if
you'd like to spend some money, how about a Cushcraft AR-10 Ringo (approx.
$50)? I worked a fellow in PA using one mounted on his roof, and he said he
loved it.

Hi gang,

Well just got Chuck Adam's note: I personally think he is
famous.. evertime I call to order a kit (from almost anyone
who sells them) they all know Chuck.  I did finally find one
kit company that he hasn't built a kit from.. May be I can
beat him to it HI HI.

Well been listening to some of the comments. Maybe we can
figure out some logical times on certain freqs and certain
bands and call CQ USE at specific time periods.  Think it
might be a neat INFORMAL net.  I think 20-30-40 might be
good. I have had real good experience with all three on QRP.

Well, just a thought.

I found a simple dipole fed by 50ohm coax did not load well.  I
dropped the ends down and created an inverted V which loaded.  I
ended up with almost a 45 degree droop before a decent match was
established.

That's weird. A "pure" horizontal dipole is around 70 ohms and should load
fine with 50 ohm coax, IF the dipole antenna itself is indeed resonant at
the frequency in mind. I suspect maybe it was not and required some pruning.
Going by the formula "468/freq. in MHz" may not apply in your case if there
are too many surrounding objects and, perhaps, the antenna is too low to the
ground. In any case, drooping the wires to 45 degrees does indeed reduce the
feed impedance to 50 ohms.

By the way, what WAS the SWR when the antenna was horizontal?

Hmmm, nobody caught the obvious error(s) in my otherwise good post or
perhaps you are all such nice guys that you thought you wouldn't mention it :-)

A square wave (with 1:1 mark:space ratio) has only odd harmonics. This
means the basic ideas presented are OK  (and the basic conclusion is
unchanged -- you need a LPF on the output) but the numbers are wrong.

The amplitudes of the harmonics of a square wave goes as 1/n**2 (did I
get this wrong too?)

The first spurious emission is the third harmonic which will be 1/9 of
the fundamental in amplitude and 1/81of the power of the fundamental
(power goes as the voltage squared). This implies the spurious
emissions are about -19dBc. The FCC wants -40dBc or better.

Anyone got a spectrum analyzer and a square wave oscillator to check
this revised figure?

 Both Siliconix and Linear Technology are sources for
 Synchronous Switching Regulators.  As Kevin Purcell pointed out,
 efficencies greater than 90% can be expected.  Although the
 technique for Synchronous Switching Regulators has been available
 for many years, their widespred use has until recently been precluded
 due to their complexity.  Now available in IC form, although
 not as simple to use as LM317s, their complexity is greatly
 eased due to their integration.  Advantages are that they can source
 highly variable loads without the tendency toward instability at
 light loading - indeed several amps can be supported with ideling in
 the microamp range.  Disadvantages (or rather concerns) would be the
 variable frequncy nature of their opperation and special care
 required for such fine points as low ESR output capacitors -

Hello....Jeff writes regarding the use of a 5/8 wave vertical on 10 meters.

I had some real success with a converted CB 5/8 wave ground plane on 10
using 40 watts of AM back in the late '60's.  (Yeah, just qualified
for QCWA...feelin' a bit of an O.F.)  I used several long wire antennas
and a trap vertical (quarter wave) all in pretty close proximity.  The
5/8 most always did better for the long haul stuff, but any short haul
stuff was better with the quarter wave trap vertical, and, on occasion,
my long wire was pointed just right and would pull them out.  The CB
antenna was real broad banded and sturdy.  Got it for nearly nothing
from an ex-CB'er (there is a source!)

Of course, your results may be different, but the 5/8 wave design is
tried and true - and works a couple of db better for most folks.  I
suspect that the better the ground and the lower the horizon around you
the better it will do at your particular installation.

Wow! I have never had so much response from ONE message in my life!

Thanks for making me feel so welcome on the QRP mailing list. Here
are the specifics for ordering the A.E.A. versions (made by Mizuho in
Japan) MX-28S from the outfit that bought the entire line from AEA
when AEA stopped selling them. J-Com is the current USA distributor
for the Mizuho line.
Only the 10 Meter version is on sale. You can order from the USA via
telephone using a credit card and have the unit the next day via UPS
Red Label from Canada.

Atlantic Ham Radio LTD.
368 Wilson Ave.
Downsview, Ontario
Canada   M3H 1S9
[phone]

The total cost: including the credit card currency conversion fee and
the UPS next-day Air delivery is $200.00 CDN or $165.00 US

The UPS Customs clearinghouse will send you a bill for about $7.00 to
pay the US Customs on the purchase.

Now, next I will attempt to upload a file with the specifications for
the Mizuho line.... wish me luck!

Well group,

people seem to like 30 meters... how does 10.120 at 01:00
UTC sound?  We could start any night (how about thursday may
6th to see how it goes).

We could do the same thing on different evenings on 40 m. if
people only had access to that band..

I agree 30 is pretty good.

Put in your votes now.. or just show up and call/answer
/USE.

I have finished my 40 M VFO and it works.
Perhaps it would be helpful if I listed some of the dumb things I did
while building it.

1.  I soldered the 2N3904 transistors in backwards.  I was looking at the
wrong base diagram.  Next time I will make sure.

2.  I used copper clad perf board and a pad cutter tool.  The circuit
looks neat but it took too long to cut the pads.  Next time I will
try a variation of ugly construction that uses copper clad perf board.

3.  I had to fiddle with the disk capacitors around the air variable
more than I expected.  Of course I didn't have the air variable
specified (who does) and I had to fiddle with the circuit to get what
I wanted.  I didn't calculate what I needed, I just did cut and try.
Next time I will calculate.

4.  I removed a 4.7 k resistor from the circuit that seemed to not make
it work and I don't understand the reason the resistor is there.
The circuit I used was the VFO from the Optimized QRP rig in the 1992
Handbook.  There is a 4.7 k resistor in the circuit from the secondary
of T1 back to the VFO buffer.  When I looked at the waveform of the
VFO on my scope it looked bad.  I suspected the resistor and when I
cut it out of the circuit, the waveform was good.  I don't know why
the resistor is there but the circuit seems to work better without it.
So, I've left it out.

Anyway the VFO works.  Now I'm going to build a receiver.
There's probably lots of ways to mess up a receiver too.

I've always used 75 ohm coax for dipoles, but I've been away from Ham radio
for several years.  Is there a some reason why the 50/70 ohm mismatch is
better to have at the antenna end instead of the transmitter end?

75 ohm coax also has less antennuation then 50 ohm cable, allowing you to
run about a 1/3 longer cable before reaching the same power loss.

Anyways, just curious...

Jim, WD9EYB, just wrote about his newly build (and working) VFO (great
job, Jim). In his article he mentioned using an unspecified variable
capacitor; my question is, how difficult and/or accurate is it to
try to measure the area of one of the plates, the spacing between
the plates, and calculate the actual capacitance? I guess a micro-
meter is needed to determing the spacing between the plates, right?
Gosh, what a headache!

Is there an easier way??

I don't agree that 75 ohm coax has less attenuation than 50 - it depends on
the makeup and diameter of the cable itself. Perhaps you mean "all things
being equal, 75 is lower loss than 50".

The lower the inherent loss of the cable, the less important to have a
perfect match at the antenna. (Thus the use of LADDER LINE or TWINLEAD for a
single dipole that operates all bands via a transmatch.) For a simple
dipole, a transmatch at the transmitter can easily tune out the 20 ohm (or
whatever you call it) difference. But, it's probably a better idea to NOT
use one in this case - I sure wouldn't.

I once operated a 20 meter horizontal dipole with 50' of RG58 and worked the
world with my Heath HW-32. SWR was minimal. Moral: don't worry about it.
Well, not too much....Of course, at QRP levels one does have to lose a
LITTLE sleep over this.

Build an oscillator (not much to it a FET GDO thing is all you need)
and stick a frequency counter on the output.

Compare the variable cap to some fix value caps you can switch into the
circuit.

A little bit of math will tell you the numbers you want.

If you don't have a capacitance meter, here's another way to accurately
measure the value of any small cap, including a variable:

1. Build a simple VFO circuit that operates around 3 or 4 MHz.  One from
the Handbook will do.

2. Measure the frequency of the VFO when a few different KNOWN value caps
are paralleled with one of the existing VFO capacitors (one that is
connected to the inductor).  The known caps should be 5% or better, mica or
polystyrene preferably, having values of say 15, 75, and 150 pF.

3. Plot this data (freq vs. cap size) on graph paper, and draw a line
connecting the points.  The relationship should be roughly linear unless
you used a very high or very low L/C ratio in your VFO circuit.

4. Test unknown caps by paralleling them into the VFO circuit.

This method works very well for me.  You can even get a rough idea of the
capacitance of diode and transistor junctions this way, assuming that you
isolate the component from the VFO's DC path.

While thumbing through my most recent issue of QST I noticed an
add for an MFJ QRP tranceiver.  I don't remember the price, but
it was close to $150 or $160.  The thing I was disapointed most
about was that for most bands it only covered a small portion of
the band.  Is this normal for such a tranceiver?  The other thing
of course is that it only covers one band, but then I suppose most
rigs that cover more than one band cost quite a bit more.  (But
then I sort of have this gut feeling like I shouldn't have to
pay as much for QRP as for higher wattage--that was supposed to
be one of the attraction of QRP--that you could get on the air
for fewer $$.)

What do others think of the rig?

Cc: [e-mail]

The saga starts:

I decided I wanted one of these rigs so I just gave them a call and
came away with the following points:

0. If you ask for a Mizuho MX-28S you get nowhere. If you ask for the
10m HandyTalkie then they know what you are talking a-boot.

1. The good news: the rig is only $159 CDN if you pay by money order,
cheque or cash, $165 CDN by credit card.

2. The bad news: The only shipping mode they use to the USA is UPS next
day air for $38 (gasp! You can build a rig for that!)

3. The worst news: I got a shop person who consulted with their manager
and he wouldn't take my order over the phone. They have had problems
with credit card fraud and bad addresses. He told me to call and talk
to their owner (Mr Lutz) tomorrow about a credit card order. I presume
they don't have online credit card validation in Ontario yet, eh?

4. They will ship to the US on a money order (no GST) for the right
amount in shipping.

So I haven't ordered one yet :-( Anyone else succeded yet. Perhaps they
are wondering why they have a lot of weird American calls for this rig
in the past day?

With the big shipping fee I'm thinking of consolidating a couple of
orders. Any one in the PNW interested?

Wow! I have never had so much response from ONE message in my life!

Thanks for making me feel so welcome on the QRP mailing list. Here
are the specifics for ordering the A.E.A. versions (made by Mizuho in
Japan) MX-28S from the outfit that bought the entire line from AEA
when AEA stopped selling them. J-Com is the current USA distributor
for the Mizuho line.
Only the 10 Meter version is on sale. You can order from the USA via
telephone using a credit card and have the unit the next day via UPS
Red Label from Canada.

The total cost: including the credit card currency conversion fee and
the UPS next-day Air delivery is $200.00 CDN or $165.00 US

The UPS Customs clearinghouse will send you a bill for about $7.00 to
pay the US Customs on the purchase.

Now, next I will attempt to upload a file with the specifications for
the Mizuho line.... wish me luck!

Subject: Re:  Jim' VFO

There are much better ways. Here are just 4 of them.

1. Build a L/C tuned oscillator (using know L and C values). Measure the
   frequency with a frequency counter. Add the unknown C to the tuned circuit
   and again measure the frequency. Than solve twice for C using the formula
   for resonance. The difference in C will be the value of the unknown C.

2. If you don't want to build an oscillator, just build a parallel L/C tank
   circuit and with a grid dip meter, determine the resonant frequency. If the
   L is known, just solve for C. If L not known, make 2 tanks (changing C) and
   with the 2 readings, you can solve for the unknown C. Note: Since most grid
   dip meters do not have sufficient calibration, its helpful to measure the
   grid dip meter frequency with a frequency counter.

3. Build a simple ac bridge circuit (see "test and measurement chapter in most
   handbooks for circuit details).

4. Using a couple of NE555 IC's its easy to build up a circuit to measure
   capacitance directly using a frequency counter or dvm. Most project books
   for the NE555 have circuit details (or see back issues of ham radio pub-
   lications, popular electronics etc.). I've built several of these and
   they measured from a few pF to many uF with accuracy of better than 3%.

If you don't have a capacitance meter, here's another way to accurately

1. Build a simple VFO circuit that operates around 3 or 4 MHz.  One from
the Handbook will do.

2. Measure the frequency of the VFO when a few different KNOWN value caps

The saga starts:

I decided I wanted one of these rigs so I just gave them a call and
came away with the following points:

0. If you ask for a Mizuho MX-28S you get nowhere. If you ask for the
10m HandyTalkie then they know what you are talking a-boot.

1. The good news: the rig is only $159 CDN if you pay by money order,
cheque or cash, $165 CDN by credit card.

2. The bad news: The only shipping mode they use to the USA is UPS next
day air for $38 (gasp! You can build a rig for that!)

3. The worst news: I got a shop person who consulted with their manager
and he wouldn't take my order over the phone. They have had problems
with credit card fraud and bad addresses. He told me to call and talk
to their owner (Mr Lutz) tomorrow about a credit card order. I presume
they don't have online credit card validation in Ontario yet, eh?

4. They will ship to the US on a money order (no GST) for the right
amount in shipping.

So I haven't ordered one yet :-( Anyone else succeded yet. Perhaps they
are wondering why they have a lot of weird American calls for this rig
in the past day?

With the big shipping fee I'm thinking of consolidating a couple of
orders. Any one in the PNW interested?

Wow! I have never had so much response from ONE message in my life!

Thanks for making me feel so welcome on the QRP mailing list. Here
are the specifics for ordering the A.E.A. versions (made by Mizuho in
Japan) MX-28S from the outfit that bought the entire line from AEA
when AEA stopped selling them. J-Com is the current USA distributor
for the Mizuho line.
Only the 10 Meter version is on sale. You can order from the USA via
telephone using a credit card and have the unit the next day via UPS
Red Label from Canada.

The total cost: including the credit card currency conversion fee and
the UPS next-day Air delivery is $200.00 CDN or $165.00 US

The UPS Customs clearinghouse will send you a bill for about $7.00 to
pay the US Customs on the purchase.

Now, next I will attempt to upload a file with the specifications for
the Mizuho line.... wish me luck!

While thumbing through my most recent issue of QST I noticed an
add for an MFJ QRP tranceiver.  I don't remember the price, but
it was close to $150 or $160.  The thing I was disapointed most
about was that for most bands it only covered a small portion of
the band.  Is this normal for such a tranceiver?  The other thing
of course is that it only covers one band, but then I suppose most
rigs that cover more than one band cost quite a bit more.  (But
then I sort of have this gut feeling like I shouldn't have to

for fewer $$.)

Hello all:

Just looking for fellow QRP addicts in the Southern California area.  I like
to work Field Day out in the hills here, and looking for others similarly
interested.  I worked with the Zuni Loop QRP Mountain Expeditionary Force
(whew!) and their giant wire arrays last year....and enjoyed a real
good earthquake (we were close to the epicenter in Wrightwood, CA.)

I will probably work with the Zuni Loopers again (really insane, fun
bunch of guys, and good food .....) but am curious as to who else is out
there, where they go and with what sorts of equipment and intentions.
If any of you are without a Field Day affiliate and want to fill in on
40 CW after I fade, let me know!!

That's about right.

My 30m MFJ rig covers the whole band. I believe the other rigs cover the entire
portion that is normally used for CW. And as far as I know, that is
conventional for QRP rigs.


>The other thing
>of course is that it only covers one band, but then I suppose most

Monobanders are now conventional, partly because they're easy to make portable,
partly because they're SO MUCH easier to build, and partly for the related
reason that they're so much cheaper.

>But

Where can you get a higher-powered monobander for $160 or so? I'll have one!

>What do others think of the rig?

I love my 30m unit.. especially the receiver, which is a single-conversion
superhet (not a DC, like so many of the QRP rigs, including my HW-8), with much
dynamic range, excellent agc, excellent selectivity, and adequate sensitivity.
I get very good reports on the sound of the transmitter, and these come from
knowledgable folk who actually know what clicks and chirps sound like.

My only complaint, and one MFJ has told me how to fix, but which I haven't
fixed yet, is that after longish periods of transmitting I get a little drift.
MFJ say it's the LO crystal expanding with the increase in ambient temperature
due to the finals. They have told me how to heat sink the crystal to stabalize
it (something I'd never have thought of doing, but they say it's an old
commercial op's trick), and they say if that doesn't work, they'll send me
another crystal (presumably not ALL LO crystals exhibit the problem).

In short, I love it, and I've found MFJ helpful and cooperative.

Remember:

1. QRP rigs have to have all the stuff a QRO rigs have, the just miss
the linear (generally just one stage of the PA). Missing this off
doesn't save much money. In fact the smaller volume production tends to
increase costs. Check out the high volume Japanese rigs (which can all
go QRP easily these days). The TS140 and IC-735 make excellent all band
QRP rigs.

2. QRP rigs are often aimed at the CW market (this MFJ rig is) and all
the CW activity is below 14080. Activity above 80kHz above the band
edge is the other digital modes: RTTY, Amtor, Packet etc. The QRPers
tend to cluster around 60kHz above the band edge (in the US -- the rest
of the world is sometimes different on different bands). So the rig
covers the range you would want given the limitations of the mode.
There is no sideband on this rig so there is not much point in covering
a higher frequency.

Complain, complain, complain! The Rig is STILL only $165.00 US even
AFTER all the shipping and stuff. What do you want? It is a $350+ US
rig going for $165.00 and you want to niggle over their shipping and
credit verification practices? Be brave, be bold, be extravagant, AND
save $150.00 US in the process. I just phoned them up and gave them a
credit card Number and they verified by calling directory assistance
and confirming that I was listed at the address I gave for shipping.
The rig was ON MY DOORSTEP THE NEXT DAY. And the $35.00 charged for
shipping was in canadian dollars, not US dollars.... I have no
complaints. :-)

If I were to buy a real QRP rig, for one band, should I get one for 30 or
for 20? (I recently worked a fellow in KY with his new 20m MFJ and he
convinced me to get a 20, but I can't remember why! Must not have made that
great an impression on me....)

I'd think 30 is better because it's open - at least to SOMEwhere, almost all
the time. 20 can be fun, but it sometimes closes for repairs or for
inventory.

Jim, WA6GER and I are hard core QRP nuts, and we have been meeting at the

Livermore, California swap for a couple of years.  In fact, we even went to

Dayton this year to meet the QRP Gurus there.   While at Dayton, one of the

forums was forming local QRP clubs, and it really inspired the two of us.



We have been kicking around the idea of starting an informal QRP club

             (read that no boring business meetings),

that would meet at Livermore at 10:30 or 11:00 AM after

the swap dies down.  Everyone would bring their QRP stuff for a show and

tell.  We will have a table at the June swap and we will be located right

by the Livermore Club's booth by the concession stand.  There will be several

qrp rigs there plus a couple of gadgets that we have, OHR Wattmeter for one,

plus we will have an operational station.  You are invited to stop by and

become a charter member of the Northern California QRP Club.  It will be

referred to as the NorCal QRP Club.  We plan on issuing numbers and having a

quarterly newsletter, but we will mainly get together and show and tell QRP.

Stop and see us if you are interested.  72, Doug, KI6DS

That's one of the reasons I chose 30. Another is that compared with 40, which
can also be fun, antennas are relatively compact and easy to make. Yet another
is the power limit: my 4 watts is less than 20 db below the limit. (Not a
practical factor if you're running 10 mw, I'll admit.)

On the negative side, however, if you're a wall paper collector don't forget
that neither the big contests nor DXCC include 30.

I caught it, but was a nice guy :-)  (too busy to reply :-) )
Still think you're wrong - I beleive *power* goes as 1/n**2, as I can
barely see -20db distortion on a scope.  I have an analyzer, and when
I looked at it I got approx -6ish for the 3rd.  Will double-check on
Friday with the comm analyzer and a 20M oscillator.

Also, FCC regs want -30dbc if you're power out is <5 watts, if over 5
they want -40dbc *or* some small level, whichever is less.

ps if you're the one building a DDS rig, Analog Devices has been a real
bear to work with - AD9955 lead time is 22 weeks for samples, they won't
sell partial trays, the price for <100 pieces is *very* high, they don't
let *ordinary* people buy the eval kits and so forth.  I've had much
better luck with Qualcomm...

As I recall, qsos on *any* of the hf bands, including 30, count for basic
dxcc.  There's no 5bdxcc endorsement for the band like there is for 12 and
17 though.  As this cycle continues to decline, I expect the band to be
more and more important for dxing.  Even now, the pileups can at times
rival anything you'll hear on 40 or 20.

A week or so ago I worked a 3B8 on 30, admittedly with full 100
watts....Anyway, that's halfway around the world. I'd say DX is out there,
"even on 30!"

By the way, I've heard of 3 ways of getting the power down to 5 watts on my
IC-735: One is an internal switch that changes the power range from 10-100W
to 5-50W; another is constructing something to insert into the ALC jack in
the back of the rig; and a third is adjusting some internal control. The
first option is out of the question; the second is, well, I don't like
messing with stuff like that; and the third is, well, I don't like messing
with the internals. Any other ideas?

A weird aside: 5bdxcc now means any 5 bands: 6m and 2m dxcc now count
towards 5bdxcc. But I doubt QRP 2m DXCC will fall for a while (though
with satellites I might be eating my words soon ...)

Once again the ARRL strains itself to contain progress :-)

The W9GR DSP kit has been sold, thanks for all the interest in it. I really
enjoy my DSP and am waiting for some real heavy line noises to return so
I can give it a true test. They seem to have disappeared lately, maybe they
know I got a DSP? Seriously though, it has done a nice job on the few

No complaints (well, not many!) just information.

I just called  Atlantic Ham Radio again and talked to Mr Lutz. He
wouldn't take a credit card order over the phone (even though I told
him I'm at Microsoft and a call to the operators would verify that --
guess it doesn't mean I'm not a crook :-). He was even reluctant to
take a money order, but if I say I'll make no claim on warrenty then
he'll sell me one. He claims that costs him money posting a bond of $40
when the rig comes into Canada from the USA for warrenty repair. This
makes it too expensive for him to sell to the US and make a profit (he
isn't making much profit on these rigs, I suspect).

All in all an interesting experience, having never bought anything from
Canada by mail order before. I've had less trouble buying products from
a US company when i was in the UK. I don't think I had to try to
persuade a dealer that he really wanted to sell me a product before!

If anyone does any better please let me know! I know J. Sherwood
Williams managed to get his via a cedit card order. Seems strange to
get it rushed by next day air after waiting for several days for a
letter to arrive. I guess I'm not really into forced instant gratification!

I also asked him if he picked up any of the 6m rigs that AEA had ... he
said they had all been sold by AEA.

Despite all this I think I'll mail an order tomorrow.

Why not build an in-line attenuator which would drop the power to the

QRPers,

A couple of more administrative notes about the mailing list.  First of
all, including portions of previous messages in your replies to the list is
OK, but please try to keep it to a minimum necessary for context.  We
generally don't need to see the whole original message every reply.  Many
people find it annoying to get three lines of reply which include thirty
lines of original.

Second, a few people have had problems responding to mail on the list,
finding that when they use the "reply" feature of their mailer, it goes to
[e-mail] rather than [e-mail].  This could either be the
fault of the person's mailer or the list mailer here.  The mail headers you
receive should list the "To:" address as [e-mail].  The "From:"
address should be the person who sent the message, not qrp-request.  If
there is a "Sender:" header, it should be [e-mail].  There
should be no "Reply-To:" header unless the original person who sent the
message put one in.  If you think the mail is incorrect as you receive it,
please send me a note at [e-mail], and include headers of a
sample message if you can.  Thanks!

I do not believe this is true.  You must still obtain DXCC on 10/15/20/40/80
to qualify for the 5BDXCC award.  *HOWEVER* you can get endorsements for
160/17/12/6/2.

Well,

I saw a nice straight key in the CQ Radio Kits catalogue out
of Bradford, Ont.  I sent a plain old personal check.. I got
the key.. best I have ever seen in perfect condition in
about a week.. he didn't even have time for the check to
clear.

I mailed an order to Schurr Keys in W. Germany for a set of
mini-paddles and had to use a bank check.. but in a very
short time the paddles came air-mailed to me.. NO PROBLEM.

Sounds to me like the guy in Canada with these rigs is a
little bit bananas.. I would like to buy one.. but won't buy
one under conditions of having to beg with one and have it
come with no warranty.. sounds a wee bit fishy.

the bands that have novice portions.)  And novices are only allowed
to use CW!

They often don't cover all of the band.  They only cover one band.
They offer one mode of operation.  No SSB etc.  They have no bells
and whistles for which the modern rigs charge more money like
frequency memories, and fancy LEDs and blinkinlights and direct
access tunning (just punch in the numbers) and frequency counters*,
and there is probably lots more.  It isn't that I want a lot of bells
and whistles.  I am just surprised at how dropping them does not
necessarily mean a drop in price.

*I might be confused on this point.  The ARRL Advanced class exam
preparation book seemed to indicate that most modern rigs have
a frequency counter used to display the frequency.  I don't know
if this means, for example, that the Icom IC-735 does or not.

 - asks Sir Kevin of Purcell....

My favorite was when I broke in with a comment to a Hawaii net with the
power turned down all the way on the IC 735 - by mistake! They actually
heard me. So, I think you can use QRP on SSB as easily(?!) as you can on CW.

I think there ARE some designated SSB frequencies; I'll have to check the
ARRL Operating Manual.

Gang,

i have built the following from OHR:  (i'm just a crazy kit builder trying
to adjust to the lack of a heath supply....)

1.  the 20 mtr old qrp kit ($149.95)
2.  the OHR 40 mtr Spirit  ($198.95)
3.  the OHR 30 mtr Sprint  ($109.95)
4.  the OHR WM-1 wattmeter ($79.95)
5.  the OHR Audio Filter   ($69.95)  not quite sure about this one

also a 20 mtr Spirit, but it's not ready yet........ ;-)  thought i'd
try the visible part of the spectrum above 40 meters......

all the kits are super.  the original rig, advertised by Ocean
State Electronics and others, is being replaced with a new kit
(soon to be announced and sold) called the Explorer.

all the kits have double sided, silk screened, green solder masked,
plated through holes, etc. circuit boards.  good density and compact
boards.  reminds of the better heath boards.  parts are first rate
quality.

a.  the Spirit is my favorite and my full time rig on 40 meters.
    of course, the antenna is most important here.  i use a 80 meter
    long wire up 10 meters.  my hit ratio is over 98%, and this is no
    exaggaration on my part it has very little to do with my operating
    skills.  i mean, 2 watts is 2 watts is ....  if i hear them, and the
    receiver is HOT, i can work them.  i may get beat periodically by
    someone with more power, but hey, that's what qrp is all about.
    i don't mind.

    anyway, i digress again.  the qsk solid state switching is just
    beautiful.  [i ran heath hw-16 (a long time ago at 25 watts) for
    many many years just because it was the first rig to have solid
    state switching, even though the rest was tubes.]  everybody i talk
    to says the keying is super in the Spirit.

    talked to a w2 in february.  i started the rig cold turkey in a room
    where ambient temp was 60 degrees.  the guy was running a kenwood that
    had been on for 30 minutes plus.  i talked to him for an hour at 40 wpm.
    neither one of us touched the dial.  the temp compensation in all of
    Dick's, KE8KL, rigs is super.  he spends extra time at this.  Dick
    bought OHR from Doug DeMaw some time back.  i don't know the dates.

    anyway, if you can spring the bucks, get this one.  2-5 watts out.
    i set mine for 2.  i thought 2 would be a challenge over 5.  ;-)

b.  the Sprint is a very small version of the W7EL DC rig.  output is 1.5
    watts.  this one is going with me next week to houston for week long
    business trip.  also taking hw-9 to play with.

    the sprint is on 30 meters and it works rather well.  i have some
    difficulty on my long wire due to rf ground, but i'm working this
    problem out when i can get some time to play.  when at home i'd
    rather work 40 anyway.  the rig is light, sorry i don't have the
    exact size and weight, but ping me and i'll measure all of the above.
    no ads on this rig that i've seen.  maybe someone from Dayton saw
    one at the meet.

    i had Tejas' Backpacker I and never got it to work.  the OHR board
    is the size of one of the three boards in the Tejas.  anyone gotten
    a Tejas rig to work?  i talked to a BP II in St. Louis months ago,
    but the 40 beam the guy had was pointed to the east and stuck there.
    kinda interesting story.  guy was a qrp meeting and he had handed out
    a copy of a newsletter that i had done to the group that he had gotten
    from someone i had given it to in San Antonio.....  small world.
    BTW, that doesn't make me famous.....  ;-)

c.  the wattmeter and the audio filter are great.  i would not part with
    the wattmeter for anything other than a brandnew one.  in case someone
    doesn't want to bother with the assembly process.  no qrp shack should
    be without one of these critters.  three scales, 10 mW, 1 W, and 10 W
    full scale readings.  9V powered and i've left the thing on for days
    at a time and still the battery is going.....

    the audio filter is the best one around that i've seen.  i gave my
    Autek QF-1A away!!  the audio filter is based on the one in a QST
    article in Oct of 1992.  i think that's right.... yeh, that's it.

ok, phd dissertation ended.  if you want more details, send SASE,
830 Waite Drive, Copper Canyon, TX  75067-8581.  i'll try to get
ASCII copy to think.com for ftp, but don't hold me to the fire on
this one guys.  i'm against the wall already on my time line.

the explorer is gonna be in the $159-169 dollar class.  can't wait
to get one.  be the first kid on the block to own the whole set.

i am just a peachy keen happy customer.  i am not paid by OHR or
employeed by them in any form or fashion.

Hello Kevin:

I am an almost exclusively 40 meter SSB QRP guy here.  Have been for
over a year.  My equipment has been an Argonaut 509 and a Swan MB-40
there.  I occasionally use a TS-440 or TS-530 QRP also (when I NEED filters!)
My antennas are wires:  a 100 foot dipole running north-south
and a 150 foot dipole running east-west.  I am a half mile from a salt
water marsh and have a good ground under me.

I have had tremendous success.  I could list all the fun stuff, but would
probably bore everyone.  Suffice it to say that on the WAS-nets like
OMISS and 3905 CC and HHH, it was a cinch to WAS in a couple of months.
When they are listening for you, they hear you everytime!  Similarly,
though, freewheeling works just fine too!  I have even checked into
the West Coast Swap Net with W6DFG....if you've done heard this net you
know that this is an accomplishment.  Clarence even got mad at me for
repeating my words.

I have also worked some Aussies, some New Zealanders and plenty of
South America on 40 SSB at night.  Really, it is astonishing, until
you figure the science of it all.  If you have a pretty good antenna
and location, you might score "S9" somewhere far away with 100 watts
output.  Well, with 5 watts output, you don't lost too much (well,
summer noise makes it pretty bad at times.)  But you will come within
"S7" or so.....with 5 watts.  NOW, suppost you actually take care to
optimize your antennas, tuner, feedline....and you use a carefully
chosen mike and maybe even a reasonable speech processor.  You can narrow
the gap considerably.

I am sure that, with a little effort (and maybe split operation), DXCC
would not be impossible at all.  Some work, for sure, but when the
Aussies roll in and you get a "5x5" report and chew the fat for almost
an hour, you figure you can do it.  Just a matter of catching the
ionosphere at the right times!

The techniques are probably well known, maybe even simplistic, but here is
what I do:

1.  Anal retentive antenna work, choice of low loss line, etc.
2.  Anal retentive tuner, cable work.
3.  Struggle for the best ground possible.
4.  Compare mikes and choose the one that gets through.  Pick up a speech
    processor that does not sound too harsh but keeps that wattmeter needle
    pointing to "5". :-)
5.  Just call as though you were a normal powered station (QRO) and
    do not make a deal of being QRP, unless it is pileup situation and it
    might be helpful.  I find that if I keep a low profile, the effect is
    much greater when the guy asks me what I am running.  This is AFTER
    we have already exchanged "5x6" reports both ways.....I seem to get
    more respect this way.  When mobile QRP, I will often make a statement
    about being QRP because I suspect I am usually way down, and I want them
    to listen.  It works.


I do not personally look to the QRP SSB frequencies because I have heard
no activity there.  I hang around down 7200-7240 in the evening.  I have
found a smattering of other QRP folks down there, and am about halfway
to QRP/QRP SSB WAS on 40.

Anyway, I will keep this short, but I can go on forever.  Really.  I love
40 meter QRP SSB!

SSB and QRP even with milliwatt power do mix. I have worked alot of DX on
SSB with QRP. There are many DX countries which are mostly or solely active
on SSB. By operating CW only one either has to wait a long time for someone
to activate the country on CW or miss out on working it alltogether. To a
true CW only op, missing it probably won't matter but if one wants to
maximize their country count some SSB operation is a requirement. A few ideas
on QRP SSB:
      Optimize your audio - pick a microphone, try more than one, and run
on the air tests with someone nearby you to determine which suits your voice b
best.
    If at all possible use speech processing. RF processing is best.
Again, adjust it and check your signal quality with others on a quiet band.
The higher average power from processing is only an advantage if the signal
remains clear and intelligible.

These comments are geared to DXing on SSB, general ragchewing would probably
not require so much effort. Just finding a clear spot on the band would be
important.
    As for 40m SSB from the East Coast, Europe can be easily worked
on contest weekends late at night after the activity diminishes. The
broadcast QRM makes contacts hard at times but the contacts can be made.

Read my post again!

The first statement was refereing to QRP rigs that are derived from QRO
rigs (Argo II, TS-120V, TS-130V, TS-140V (dunno if this exists), low
power version of IC-725 and 726). These are either made as dedicated
QRP rigs (and have small runs) or are made for the Japanese 10W HF
no-code licencees and are not sold outside Japan.

The other QRP rigs are made in small quantities (by people not robots)
and cost more as a consequence of having such a small volume
production. Remember Icom, Yaesu, Kenwood supply the world. MFJ is
really only aimed at the US market, though you can get them in the UK too.

Also the blinkenlites are mostly a software cost for the controller.
This can be large and works better for a unit with high volume sales.

Not covering noice bands is done for several reasons:

1. Novices are usually pretty bad at copying weak signals (not a slight
its the truth!). There is no driving force from the users for this in a
portable rig.

2. For CW work with a tight filter you want a low tuning rate. With the
given components (vernier drives) that are easily availible and the
requirement for a slow tuning rate (25kHz per turn or less) to make it
easy to use they're encourged to limit the span covered. This general
goes from the bottom of the band to where the digital guys take over.

An all singing all dancing all band portable single conversion (50MHz
IF) QRP rig with digital readout, optical encoder dial, that can work
split, that'll run for a weekend on a single gelcell that would sell
for $600 would be great. But there aren't any rigs out there like that
(yet!). KG7ME has a working prototype of a rig fitting these goals and
is considering putting it into production. I have seen it at a NW QRP
club meeting and it may be at the Convention in Seaside, OR this June
if you want to see it. Maybe that'll be the answer to our problems.

The market is there you just need some entrepreneurs that can fill it.

I built a 20M SSB transceiver that runs about 1 watt out. As you you know I'm
99% building, 1% operating, but I have great success with this unit. I just
find a strong signal and call the station when they finish the QSO. Get about
90% hit ratio using this method. Answering CQ's with 1 watt on 20M got me a
50% hit rate. Calling CQ was a waste of time. Signal reports tended to be S7
to S9 and antenna is a 68' end fed wire (w/i 200' of ocean). Found the 20M
SSB QRP frequency not active with QRP ops.

This is slightly off your topic, but of interest.

About 6 weeks ago, a local HAM club had the head of Yaesu marketing
show a film & give a speech.  (Hey, Yaesu & everyone else is near
here).

There was a Q&A session at the end.

Afterwards, I kicked myself. (ouch!).

The marketing guy had said that they get most of their ideas
and input from their customers.  I blew it.

I should have said: "QRP is one of the most rapidly growing
segments in HAM radio today.  Does Yaesu have any plans to
produce products for us?".


A few of us asking vendors questions like this may make them
respond to our needs.

I am mentioning it just in case any of you are in the same
position oneday.

I say:

They already make QRP rigs for the home market (the 10W code-free HF
licence). I know of the TS-120V and TS-130V and FT-7 but there must be
many more that we never hear about (Mizuho or Tokoyo HyPower).

If they would bring these rigs into the US they would make us happy (to
some extent).

Getting them to make specialised rigs is more of a problem, but if we
keep asking.....

QRPers -

   Yesterday, I spoke with Danny Stevig, owner of KA7QJY components
of Logan UT.  Nice guy, spoke with him for about 30 minutes.  He
is planning a vacation in a couple weeks, so if you're planning an
order, he recommends doing it ASAP to avoid delays.

   He is planning on offering a few kits in his new catalog (due around
July '93 sometime).   He is also looking into a cheap source for
crystals, so us cubic incher wannna-bes can build the circuit without
need for a $12+shipping crystal.

   BTW, I have no affiliation with KA7QJY, other than being a
satisfied customer.  This note is being passed along strictly FYI.

Good luck, 72, and happy homebrewing.

Subject: QRP list QSO party

I made a pretty brief appearance on 10.120 tonight, long enough to work
Jeff AC4HF and Clark WA3JPG.  Conditions around 10.120 were pretty brutal
up here, with a broadband rythmic noisemaker at 10.121.  A few kHz lower
would have been clear.  I QSYed down to the QRP-NE party on 3.579 and
worked a couple of other list members (Jims KR1S and W1FMR) as well as a
few Internet-impaired QRP NE folk.  Nice to hear those I heard, and I'd
love to hear of others among us who managed to QSO.

Bruce Walker

Nice talking to you last night on the "May Daze Sprint",
(QRP-NE Thurs. eve QSO party).

I used the Argosy at first, but the guys were having
so much fun running xtal control, I fired up my
"Colorburst" special.  Put a 150 pf  variable cap
in series with the xtal, (using Radio Shack clipleads),
and got about 7 khz of freq. shift.

What a blast !

Worked KN1H, WT1M, VE3DRB, NN1G, WA1JXR, KR1S, and a few
  others.

My output was 1 watt to a 140' wire, an ultra simple
HB tuner, about 150' of various length ground wires
 (3) laying on the grass.

Hearing the gang and working them all was a gas !!!!

More fun than I have had in a long time;
Especially from a little HB square of parts hooked to
a gell cell and key.

Only one (1) switch was used.

The antenna was switched from tx to rx.
The Argosy was used as the rcvr, and the AGC circuit in
the Argosy took care of the audio level perfectly.

Simple and very efficient.......

Looking forward to QSOing you next Thursday, and
seeing you with the QRP-NE  group this weekend at the
Rochester NH  Hamswap.     QRP-NE Club meeting just after
the drawing ( if they have one) on Sat.  ~ 1:30 pm.

Jim, W1FMR

Well, Bruce was accurate, 30 was noisy....very noisy.  Here on the
West Coast I could just pull Bruce, WT1M and Jeff, AC4HF out of the
mud.  I was running a full QRP gallon of 5 watts, while the others
ran a bit less than I did.  It was fun to readjust my manual key
again....it is getting a little better each time.

Gang,

probably many of you know or have heard of Luke.  i just got a
letter from him.  he underwent open heart surgery April 12 - 24
and is now back home.

Luke is the treasurer for QRP ARCI and he is also the US rep for
G-QRP club, he handles membership for the US of A folks etc.

those who know Luke may wanna drop him a card and wish him well.
or, you can send me email and i'll see that he gets it.  he is
some 15 miles from me in Grapevine TX.

he and a bunch of others, including Mike Kilgore, secretary for
QRP ARCI, and myself meet first saturdays of even months for
lunch.  we're going to have to change restaurants, since Luke
had his surgery and I had an artherectomy (cleaning of the main
artery like rotter rooter) last year.  i cleaned up my act and lost
55 pounds.  now at 211 pounds, but hey gang, i'm 6'6" in height.
smallest of four boys.  my younger brothers all hit 7'0".  we grow
big in texas...... ;-)

anyway, Luke is doing fine.  say hi to him on the air or via
snail mail.

I'm confused a little by 30 meters situation relative to awards.  I thought
that 30m contacts were ok for the basic awards (WAS DXCC), just not the 5-band
ones.  Anyone out there really know what the story is???

Hi,

Well worked 2 /USE.. the band was the worst I have ever
heard it.. but still managed to get through on 3 watts with
the HW9... finally worked Clark in California on QRP..

Think if the bands improve that having a regularly scheduled
time once a week on 30 and once on 40 may be a good thing..
anyone around there radio..can just tune in.

It can be done, I've got almost a DXCC on SSB with just a G5RV at 25 ft -
it ain't as easy as CW, hitting "dead-air" with your call is absolutely
essential, else they aren't even going to know someone is there.

Techniques - use the qrp designator, why they can hear that and not the
call I don't know but its got me a lot of contacts phone and cw..it might
be timing but I do believe "qrp" gets their interest more than one just
one more callsign that happens to be very weak.

- operate where the pileup isn't. Althougth this may contradict the usual
principle of transmitting wehre the dx is listening, finding an
opening in a large ssb pileup is difficult to the point of impossibility,
if you are going to be vainly shouting into a microphone anyway might as
well do it where the frequency is clear and who knows ... maybe the dx
will tune there.

- Up to individual discretion but one way to get an open spot is to make a
call when the dx asks for dx or is going by call areas and doesn't get a
response..listen first of course...there are those that maintain a qrp
station is not going to stomp anyone and this is not an unreasonable edge.

- And since I'm dealing with controversial issues there are always nets.

Sorry - I have to disagree.  Signing QRP instead of your call is tantamount
to "last two letters", a horrible practice among good DXers.  Signing QRP
after your call just makes your callsign longer, and the DX station will
usually pick up someone with a shorter callsign first.

If I were the DX station I'd ignore "out of turn" callers.  Everyone else
should do the same.  Once you let one station through, bedlam usually
results.

Better suggestions:

1.  Work DX on the less popular bands, like the WARC bands.  There's less
    competition.

2.  Use the highest band when it's open. 5W on 10 meters is plenty loud, 5W
    on 75 meters is tantamount to suicide

3.  Tune around *a lot* to find the DX before everyone else does.
    Otherwise, you'll have to wait until the pileup dies down.

4.  Know when DXpeditions are coming, their band plans, and how long they
    plan to stay.  I worked AH3C/KH5J on Jarvis in 1989 after they had
    run out of stations to work in the last days of the DXpedition.

5.  Don't tail-end unless you *KNOW* the DX station is taking tail-enders.

6.  Operate DX contests.  Lots of good DX is begging by Sunday afternoon.

Subject: NE QRP Spring Daze #1

Up here in New England, we've been fooling around with rigs
that use color-burst crystals (3579.545 kHz). In keeping with
the G-QRP tradition of giving every piece of equipment a name,
I call these rigs 79ers.

If you live in a densely populated area, you need a lot of
patience, as the TVs are everywhere. Doesn't anyone read anymore?
With deft usage of series inductance, you can "bend" these crystals
a few kHz, and avoid most of the TVs.

NE QRP had it's first May Daze 3579 QSO Party last night, from
9 to 10 PM EDT (0100-0200 GMT). W1AW operates CW on 3581 kHz, so
we had to clear out before they got started at 0200. The span of
frequencies I observed last night was 3579.3 - 3581.3

I use indoor wire antennas. I know I can do better on 80, but
haven't taken the time to try anything except some loops of wire.
I don't know how many stations were on last night, but I worked
everyone I heard except KN1H: W1FMR, NN1G (also in Newington),
VE2DRB, WA1JXR, WT1M (whodat?).

About 0140 I went down to 30 meters for a while, but I only worked
a couple of 4s. Guess I missed the Internet crowd. (I was watching
"The Real West" on TV...) Let's see some activity reports from
those of you who made it!

Subject: QRP Icom 735

This week someone asked how to turn a 735 down to qrp levels.  Last night I
did the agc trick that was in QRP Quarterly, July 89, page 8.  It was written
by Mike Michaels, w3ts.  All the circuit has in it is a battery connector for
a 9 volt battery, a 10k resistor, 68k resistor, 10k pot, switch and a 1x2x3
minibox.  Took about 5 minutes to build, and worked great.  I hooked it up
to my Icom 735, tuned it up, and turned it on.  I was able to adjust the
power from 2 milliwatts to 5 watts.  I then called a group of guys on 75 meterss`.  They gave me a signal report of 57 and then would not believe me when I
told them how much power.  Measured it on Oak Hills Research WM-1 Wattmeter.
So, I turned up the power from 20 milliwatts to 5 watts.  They could see a
difference!  One guy still would not believe me so I went to 100 watts (sorry
guys, but I was proving a point).  He believed me finally.  This mod works
great, is easy, cheap, and even I got it right the first time.   If you need
the circuit and don't have a copy, drop me an email message and I will send
you a copy.  72, Doug, KI6DS

My experience was similar. I listened on 10.112 and heard no one; called CQ
USE a few times - nothing. Then I QRO'ed on 10.113 and worked a fellow in NY.
The band was not at all as noisy as it was the night before.

I have the 40 mtr OHR DC receiver QRP rig.  I love it!  It worked the
first time I fired it up.  OHR has been extremely helkpful and gracious.
Just one proviso...  This is a DC receiver with all that that implies.
Expect problems from high power swbc stations far off your frequency.  Under-
stand that you'll hear 2 of every signal.  I've worked EU, AF and coast-to-
coast with it.

Subject: RE: QRP calling freqs

Hmmm, I was looking through my QRP books yesterday to check on these
figures, but you saved me the effort of typing them in (great minds
think alike, uh, Chuck :-)

One thing that struck me is that EVERYONE omits 17m band from these
lists. Is this because it was the last WARC band opened up to US hams?
Are there any recognised CW and SSB QRP frequencies on 17m -- or do we
just use the whole band :-)

I also note that there is a move afoot to move the 10 SSB QRP frequency
down to 28.360 at least in Europe (the most recent SPRAT mentioned it).
It seems sensible as there is a lot of activity in the 28300 to 28500
Novice/Tech subband.

Finally it seems that the Novice/Tech subands (except the 10m subband)
should be a good place for QRP (though underused) because the QRO guys
have to throttle back power to 200W PEP or less? Why don't QRPers make
more use of this? You may even infect a Novice/Tech operator with the QRP bug.

Dr. Martin Zurn, HB9/DL1GBZ es IK2RMZ, pointed out that i omitted
12 and 17 meters.  sorry, but the list i had didn't have those.

Dr. Zurn gave 18.096 for 17m and 24.906 Mhz for 12m as calling freqs

Actually, Kevin, I do this. I like running QRP in the 15 meter and the
80 meter novice sub-bands. They get a kick out of my power output. I
use an old 6L6 tube xmitter. Can't wait to get one of those next solid
state rigs to go camping with.

Has anyone ever noticed how accurate the tuning dial on an HW-8 is?  When compared to a calibrated
receiver, the HW-8 is +/- 5KHZ.  Is this about right from your observations?

i'll be on everynite starting highest band and working down as
they close.  look at the qrp calling freqs.  look on 10 if it's
open on sunday afternoon (SSB first, CW second) for mobil work.

work rare counties.  i'll drive 40 miles outta the way if its

Has anyone had any experience in building the Twinlead folded diplole
antennas listed in the Antenna Handbook? I built the 10 Meter version
 to themeasurements in the book (including the 39pf Silver mica
capacitor) and can't seem to get the SWR down on the antenna. there
is a slight dip at the resonant frequency, but it still isn't below
3:1 ..... I even made a coax coke balun andthat didn't help either.
Any suggestions? I've rechecked all my measurements and all my solder
joints and just wonder what I might try next to get the SWR down to
an acceptably low QRP SWR (1.2:1 or lower)

I pruned and extended and could not get a good load.

Bingo ^ 2.  The antenna was very close to the ground.  It was about 10 feet
off the ground.  The final resting place was in the attic which was in
close proximity to many objects.

Simple, immediate fix.

Would not load...3+.

Lots of noise but didn't hear anyone calling CQ so I gave up.
