To: [e-mail]

     Hello , OM.

     My neighbour station is now making FAX-station with IBM-PC. For
his development, he asked some software about:

BASIC compiler for 8052BASIC,
or Closs C pre-compiler(or something like) for 8031/8051/8071 series.

     If you know about that or related items, please tell me.

     Thank you.

Subject: Homebrew Antennas
To: [e-mail]

    Does anybody have any suggestions on a good homebrew J-pole? Another
question is, does anybody know how to make a good antenna that is portable
enough to be carried with you while you hike in the woods and could be
set up there (a type of dipole perhaps)? If anybody has any input or directions
could you please e-mail me at the address below. Thanks in advance.

There are a couple of mods that I'm familiar with for the 22s.  If the
diode matrix is still in place andworking, then it should be a simple
matter to 'undo' the mod.  I have a schmatic and can fax it or whatever.
BTW, the 22S had a very hot receiver for its time (mid 70's). I still use
mine..

\MILLIWATT REPRINTS ON THE WAY--PROBABLY

Sorry to bother the homebrew newsgroup with this one--this is for the
benefit of the many QRPers who recently unsubscribed to the QRP
mailing list when it changed hosts and lost the digest capability.  I
believe many of you are still here on the homebrew newsgroup (and
there may also be others who are interested in this).

I'm still not taking orders on my non-profit reprinting
(photocopying) of The Milliwatt ("National Journal of QRPp"), but I'm
taking another poll, this time to see who is SERIOUSLY interested--my
partner is negotiating with the printer, who raised his estimate
sharply after Partner showed him the material to be copied.    With
the higher price the printer is now quoting, it looks like we might
have to charge up to $25 in the US/Canada, UPS-paid. (The higher
quote is still a bit cheaper than I could have done it at Office
Depot.)  If you're still interested, let me know; we need to get an
idea of how many copies to order, although this won't obligate you in
any way--you can change your mind later and back out.  (This isn't a
small document, either; it includes the entire 33 issues of the
Milliwatt, and that comes out to 180 sheets of 8 1/2 X 11 paper,
printed on both sides.)

For those who've never heard of it, The Milliwatt was the pioneer QRP
journal in the US, running from 1970 to 1975.  (The QRP Quarterly in
those days was not what we'd call a QRP journal today--that was back
when the QRP ARCI had the 100 watt limit and was not devoted to "real
QRP.")  The Milliwatt was started jointly by me and (primarily)
Adrian Weiss, W0RSP, although I ran off after 4 issues to join the
Air Force (much better than being drafted and going to Viet Nam!).  I
was publishing the precursor, a bimonthly newsletter which contained
a QRP section.  He found out about it, came on board and quickly
convinced me to convert to a 100% QRP journal, took over the printing
and bulk of the editorial responsibilities, and the rest is QRP
history.  Although I had a seminal role, W0RSP did the vast majority
of the work and deserves 99.9% of the credit for it all.

If you want a copy of the notes I put on the QRP list let me know and
I'll e-mail them, although this posting contains most of the detail.
(Again, this is a non-profit project, as was my earlier reprinting in
1992; any excess money after expenses are covered will be donated to
some small but deserving regional or local QRP club to be determined
later--and the Maryland Milliwatts are specifically excluded!)

Again, let me know by e-mail if you are still interested at this
price; I'm not taking orders just yet, but will let you know if we go
ahead with the project.

Subject: Where to find (stable) fixed frequency oscillators?
To: [e-mail]

Hi,
We want to built a receiver for an experimental magnetic resonance system.
Our experiments will be done at several fixed frequencies in the
range between 40MHz and 360MHz.
We are looking for stable oscillators with low harmonic distortion
in this frequency range.
True, we could buy Xtals and built the oscillators ourselfs, but
it seems so much easier if we can find a source for integrated oscillators.
Can anybody name some companies how built fixed frequency oscillators
in this range?

Thanks a bunch in advance,
Arne

Arne,
    How stable do you MEAN when you say you are looking for stable
oscillators? And what is your budget? (A very simple way, if a tad expensive,
to get reasonably stable low distortion signals at those frequencies are
prepackaged in almost any of the HP or Fluke or other frequency synthesizers
out there. These are usually settable to at least 1Hz accuracies. And they
are available with options for state of the art stablility crystal oscillators
and will also accept things like Rb and Cs frequency standard inputs for
improved stabilities.) (For lesser applications a few days hacking can result
in acceptable frequency synthesizers in those two ranges that are useably
good.)
