Subject: 10 GHz EME question
To: [e-mail]

> Is 46m dish any better than a 4m dish on 10 GHz EME ?

10 GHz EME with a big dish has been tried before. In June 1987 OH2TI, RC of
Helsinki University of Technology, together with OH2AV, RC of Nokia
Corporation, put a serious effort to make the first ever 10 GHz
EME contact with Goliardo Tomasetti, I4BER. Antennas used were 14m and 32m
radiotelescopes in Helsinki and Bologna, respectively. At OH2TI, we had a
8W TWT while I4BER was running 1W. The result was a one-way QSO. I4BER heard
us with a good signal but we didn't copy him. We had started, due to some
delays in Bologna, well behind schedule and run soon out of time. At the same
time we figured out that we had been listening him on a wrong frequency,
Goliardo called us to tell that he had to go QRT. The radioastronomers wanted
to have their antenna back to real research. Well, I thought that's exactly
what we were doing ... ;-)

With some more time available it might has well been a two-way contact.
Unfortunately, we never got a second chance because it turned out to be
impossible to find a common time slot during the next months, both antennas
being in intensive research use. A few months after our experiment we lost the
10 GHz EME band in Finland to "paying customers". So, that was the end of it.
As everyone knows the W5s and W7s made the first ever 10 GHz EME QSO on
Aug 1988, about a year after our test. This year it looks like we will get
the band back (10.368 - 10.370 GHz), so who knows what will happen.

So, what kind of signals did we experience ? Well, our own echoes were strong
and solid. Every single dash and dot was returned unchanged off the moon (for
more than 30 mins ). The signal was clean, not distorted like some of the Ws
with smaller dishes have reported. Maybe this was due to the narrow beamwidth
(0.17 degrees). It is hard to estimate the S/N but I would say it was around
10 dB. Theoretically our echoes should have been (with the NF 4.2 dB Rx)
about 20 dB above noise. To refresh my memory I just listened the two
tapes again. The first one contains OH2TI's echoes recorded by myself. The
other one contains our echoes recorded by I4BER. On both tapes the signal is
clean and solid. The rapid libration fading is there but it's not bad. On
432 MHz I have got used to much worse (with OH2PO's 16m dish, 3 deg bw).

A quick calculation shows that with same power and same Rx but a 4m dish our
own echoes would have been 1 dB below the noise ! A 4m dish has a beamwidth
of about 0.5 degrees, so this clearly proves that it pays off to have bigger
antenna on transmit. In the case of VE3ONT things get trickier because
a 46m dish has a much smaller beamwidth (0.05 deg) than the apparent moon
diameter and a small dish has a beamwidth equal to or larger than 0.5 degrees.
This is why VE3ONT will suffer from over 200 K moon temperature while the
small station has cold sky behind the moon, and thus benefits on receive.
Does VE3ONT's big gain compensate the lost reflection area ? I don't have
the answer to this one. It seems to me that the optimum beamwidth is smaller
than 0.5 degrees. How much smaller, I don't know.

I4BER was hearing his echoes clearly with 1W (68 dB, 0.07 deg). Assuming
that the NF of his Rx was about the same than ours (I recall it was better),
I4BER should have heard us 7 dB better than we heard our own echoes,
providing the under illumination effect was neglible. The tapes are hard to
compare because mine was recorded with audiofilter on and the other tape was
recorded without one. I would say however that the signal is stronger on my
tape. Also, providing the under illumination didn't exist, I4BER should have
heard his own echoes about 25 dB above noise with his 1W ! I don't think that
was the case.

I have the QRZ! CDROM, and bought it specifically because the callsign
databases inside were not encrypted in any way.
The callsign databases are simply comma-separated one-line-per-call
text records.

I liked this because I'm using the call database on a UNIX (Sun)
system, and can easily write database massaging code in Perl.

Oh, and yes, QRZ! was significantly cheaper.  I got mine mailorder
for $15 + shipping.
$50? I guess the Buck$master name is appropriate.

Can anyone comment regarding pros/cons of the HamCall product?

For what it's worth, I can reproduce this symptom on my FT-530
exactly.  A bit annoying, but I also like the HT a lot.

This is 3 degrees West of Indianapolis, about 180 nm.  If you're in
Indianapolis (39.77N 86.16W) then the GPS device gave you the wrong numbers
or you wrote them down wrong.

Subject: Hamfest Listing
To: [e-mail]

I've been searching around for a listing of upcoming hamfests, and have
been unable to find one. So, I've decided to do the next best thing -
create my own.

My goal is to periodically post a comprehensive listing of upcoming
hamfests, for the entire US (if the list gets too large, it could be
broken up into regions).

This is where you all come in - I need for people to email me with
details of upcoming hamfests that they are aware of. The information I
need is:

The name of the hamfest, the location, the date/times, And anything else
pertinent (cost, name of contact, etc).

Please send the information to me at: [e-mail]

Thanks,

Chris

Check out my article in Feb. 93 QST "Everything You Always Wanted To Know
About Computer-Controlling Modern Radios" (I didn't pick the title :).  It
has plans for a Kenwood interface that is opto-isolated and implements the
handshaking lines as well as the data for complete compatibility.

I also still offer the parts kits listed at the end of the article.  Prices
are the same, ($47 for Kenwood kit, $44 for Icom/Yaesu/Ten-Tec) but the
address is now:

 CW Technology
 7328 Timbercreek Court
 Reynoldsburg, OH 43068-1181

 COD Orders Only (add $5) at 800-547-7479

The kits include PCB and all board mounted parts.  You provide case and
8-15V supply.

NOTE:  ARRL has the PCB layouts and the parts are readily available - you
       do not have to buy anything from me.

I don't. I don't even want a phonepatch on the repeater. Make that I
*especially* don't want a phonepatch on a repeater. I want a repeater
to be as unobtrusive as possible, simply a bent pipe to extend my
radio range. It's a gathering spot for conversation, not a paging
service, an answering machine, or a substitute for a cellular phone.

Right, it sure could be a flipped "6".  More likely than a typo is a
