Subject: what's a 40-40 & how do I get one?

I see a lot of talk about the 40-40. What is it? Who is selling it? and
how much is it? It appears to be a 30 and 40 M QRP rig, but that's all I can
figure out.
Any help would be appreciated.

Looking to buy a QRP rig (can that term apply!).
Here's what I've narrowed it down to:

S and S Ark 4
NN1G 40/40
The A an A Engineering 40 Meter
Oak Hills Sprint or Classic.

The question - your opinion on what I will be happiest with. Only
have time to build 1 and would like to make the most informed decision.

My hot buttons are size and superhet (not absolutely required).

I am familiar with the specs so I am looking more for user opinion.

Thanks in advance and looking forward to joining your esteemed ranks.

I just got a letter from a long time ham (who bought my TT 505 years ago)
who wants a challenge. He wrote me that he and two others want to "build a
one transistor rig that is powered by a 9v battery". Kinda sounds like a
perf board job to me -- but maybe FAR has a board that these three could
buy (?)

Well, gang, there it is. Is there a design out there that is relatively
free of grief so we can get three more members in the QRP fraternity? A
good first expperience would help.

As all too many of my QRP-ARCI friends know, I made the worst mistake
possible when I replaced my tri-bander after a direct lightning hit (and,
Yes, it vaporized half of the elements). By "worst mistake" I mean it is
OK on 10M, 2 megs low on 15M and 4 megs low on 20M and no adjustment is
left!. To put it another way, it's a nice -- but costly -- dummy load.

Because I don't want to go to the extra labor (not to mention expense) of a
major tower upgrade -- unless I have to -- so, at this point I want to look
at beams smaller than the TH7's.

I would appreciate your personal (or that of other hams known by you)
comments on "CURRENT" manufacture. I say, "current" (say, last 5 yr or so)
because too much has changed over the years in durability, quality and
performance. For example, every bit of evidence available to me shows
TELREX's massive quality and support deterioration. True or not, I rule
them out. Also, please DO NOT refer me to printed reviews. I trusted them
 -- that's what got me into the mess I'm in now! I need your experience.
That,I trust!

Your thoughts please on: KLM (34-A) -- the smallest physical size of the
bunch; Hy-Gain (Explorer, TH5); and Mosely (CL and Pro series only).
There may be another maybe "Force 12" (?). I'll leave that to you.

archieved at the qrp ftp site.
You sold a TT 505 years ago? I didn't realize that TT's (teletypes?) were
around 500 years ago!!

The QSO's are slow, the propagation isn't very good and either there are
VERY FEW Internet QRP ops on, or propagation to QRP stations is REALLY BAD.
Last night 40M produced QSO's w/ VK, JA, YB, TI, KL7 and many Canadian
prefixes. Ten sounds dead at my QTH this morning, 15 and 20 have been
North America only for me -- but I have heard some Europe on 20, just
can't seem to work em. QSO total after 3-hours on-air: fewer than 50.
Come on in! CUL, 72 de alan

The "More Projects" menu is extensions to Jeff's projects, plus whatever
other projects I see online that I think are interesting and worth preserving.

Both of these are off of the W8EDU menu:

Enjoy! I wouldn't mind collecting more projects on this site, if you have

Subject: DeMaw's 40M VFO

Gang: Has anyone built the 40M VFO in QRP NOTEBOOK (pages 29-30)? It
calls for a couple MPF102's (RS has them) and a 2N222A (I've got plenty),
and I can scrounge the remaining components.

I'm going to use point-to-point wiring rather than a PC board.

Please let me hear from you if you've built one.

HelP !

I've looked and looked for R 342 on my OHR Classic TR Board - can anyone
help? I'm sure it's there I just can't find it!

Thanks in advance for the directions - BTW this is a -very- well done
kit, much better than Heathkit quality - parts, case, board and instruct-
ions are all first rate.

From: Yehuda Harper <> Date: Sun, 29 May 1994 11:23:31 -0500 (CDT) Subject: Antenna Matching

I recently built a 20 meter rock bound CW transmitter. Using a Diamond watt meter, I measure an output power of 1.75 watts into a dummy load. However, when I feed the signal into a dipole and match the SWR to 1:1, the measured output drops to 1.25 watts. If I mismatch the antenna to a 3:1 SWR, I get a measured output of 2 watts. Questions:

1) Why the differences? Why does the power output go up with a mismatch? I would expect the opposite. I've checked the output filter of the transmitter and the # of windings on the torroids and the capacitor values are correct for 20 meters.

2) Am I getting correct power readings?

3) Should I run the transmitter at 2 watts out into 3:1 SWR or 1.25 watts out into 1:1 SWR. The output transistor doesn't seem to overheat either way.

As the water surface helps mostly in the directions across it, Lake Superior from the southern shore isn't going to do you much good in Field Day. However, there are a number of peninsulas which extend out into the lake which would be quite good for propagation in many directions. If you could find a cliff with exposure across water to the south, so much the better.

You might suggest to your friend that there are a number of good books with suitable circuits around. E.g., Hayward & Demaw's _Solid State Design for the Radio Amateur_. Might also suggest dead bug construction for something that goes together quickly and works well. Might finally suggest TWO transistors -- why would you EVER choose to key the oscillator (chirp, chirp)...

72! Jim K5YUT P. S. See p. 27 in Hayward & DeMaw for "the universal QRP transmitter." Any band from 160 to 10; DOES key the oscillator on the lower bands, but not the higher; uses 2 or 3 transistors, and once you had acquired a crystal and wound a couple of inductors, could be glued together in an hour. Guess my poin t is that it's not very much harder to build something that will provide real satisfaction for a long time.

Hiya, ... ran 5-watts for 5-hours (a little Friday nite, a little Saturday morning and a little Sunday afternoon) ... and appropriately enough racked up 72 QSO's! Got some good ones on 40m -- JA, VK, YB, 20-and-15 had a lot of Carribean activity -- 6Y, NP2, KG4, KP4, VP2 and 10 yielded 3- L's (Argentina) stations! Propagation folks say there was a solar flare. And I did not hear any of the QRP Internet gang (maybe they were saving themselves for the sprint). 73, 72 de alan
