Good evening,
I realized shortly before the last FO-29 pass that both FO-29's and
VO-52's AOS were seconds apart on the east coast of the United States,
so I decided to scan the upper half of the passband in LSB to see if I
could hear any signals. I heard a weak CW signal and also a
conversation. Unfortunately, I could not copy any callsigns, but I
clearly heard a voice saying "73" as my dial read 435.902 MHz LSB
about halfway through the FO-29 pass.
Cool to hear! I know I've heard the AO-73 beacon via FO-29 before, but
never a conversation from another satellite.
73,
Paul, N8HM

WD9EWK>> ... used my IC-2820H, Elk log periodic, with the

What? FIVE WATTS?!?! You power hog ... (grin)
Just for the heck of it, I tried with an HT turned down to TWO Watts,
and a tape measure beam ... and got right through!

I believe a Boy Scout from Victorville got in there at the beginning,
too ... THEN the pile-up began! What a marvelous achievement -

Using a modest set-up, I was able to give our local club
(W1BIM) their bonus
satellite contact on FO-29 Saturday afternoon (thanks to the
team at W1AW/3).
It was on the third pass attempt.
I ran a FT-847 barefoot with an 11 ele yagi on 436 and a 3
ele yagi on 2m.
I ran SatPC32 with the custom exe I got from Erich to
address my older FT847's
unidirectional CAT. Ran out of the hatch of my Subaru,
armstrong rotor on a
camera tripod.
I have a lot of experience on the FM birds, but due to the
lack of a home station
very little on the transponder birds, at least not since
AO-40. A couple of questions:
For each satellite, once I dial in the correct VFO offset in
SatPC (using the +/-
keys), does the value stay the same pass to pass, or does it
change on each pass?
When I tried to run the ISS passes (2m up and down), the
2nd VFO on the FT-847
came up "reset" in the rig display when SatPC pushed the
frequencies over --
is that a rig issue or SatPC issue I need to discuss with
Erich?
I had a script print out that I generated from NOVA as a
back-up to SatPC32. I found
in comparing it that it did not show all available passes --
if passes overlap in the
NOVA scripting output, does it have a preference and drop
one of them?
SO-50 was pretty much non-usable except for passes over the
ocean. No surprise.
When in the right mode, I could hear AO-7 no problem , but
it would switch itself off or change
modes 1/3 way through the passes.
On VU-52 and FO-29, signals would start strong and then
dive... I assume this is
the same thing I saw from my AO-40 days on FD... as the
bandpass fills with stations,
the available downlink output must be shared by everyone, so
the overall signals from the birds
drop off significantly... is that correct?
Obviously, under "normal" conditions, it does not take much
to work the linear birds...
a quick search of "Amsat demo" on You Tube will demonstrate
that for you -- small
linear yagi's, a 2nd person on the tripod, a couple of
FT817's barefoot, and no PC.
FD is, of course, a different animal. I'd like to find out,
off line, what folks were running set-up
remote (not home stations). You don't have to post here;
please send it to me direct
(my call at hotmail dot com)
In particular:
2M: TX power, antenna type and polarization, # of elements,
RX pre-amp (y/n)
70CM: TX power, antenna type and polarization, # of
elements, RX pre-amp (y/n)
Single radio, or 2 radios?
PC control of rotor? (y/n)
PC control of rig? (y/n)
What was your goal: Give bonus points to FD effort, or full
AMSAT FD?
If folks are interested I will summarize and repost, but I
will not post any
individual station info.
We had great weather in New England, and a great FD outing.
After making the needed QSO,
I had a few more failed attempts on subsequent passes where
I had trouble finding myself.
Spent the rest of the weekend on 20CW, and trying to conjure
up an opening on 6M.

Clint,
Seeing that I did not send a message out with that
subject line (without the "Re:", of course), I was
amused to see that it was pretty much another report
of your ISS contact on Saturday, and didn't really
match up with the subject line. :-) But since you
put it there, I'll elaborate on it...
I suppose there are many of us who could have made
the ISS QSO with two watts (or possibly less), if we
had the same combination of that ISS pass and your
location relative to that pass. You know this already.
Here in Arizona, I figured I would have had a chance
if I was able to get in early, before the footprint
covered much of North America. When I ran SatPC32
yesterday to wind the clock back to Saturday morning,
I was shocked to see that the ISS footprint was all
the way out to the Mississippi River around the time
of my brief QSO. The elevation was up to 48 degrees
toward the northwest, around the time the ISS was
approaching northwestern Arizona, when I got through -
probably the best chance for me to make the QSO. I put
a screenshot from SatPC32 in my slideshow video from
the first ISS pass showing this, about midway through
the video. Location, location, location...
I had a couple of radios I could have used for more
than 5 watts transmit power on 2m (the IC-2820H will go
up to 50W, and I could have transmitted at up to 20W on
the internal batteries of my FT-897D), if I wanted to
do that. I stick with QRP power when I do my own Field
Day efforts - something I have done in most years since
I bought my first FT-817 in 2001 - for the challenge,
even when trying to crack the pileup for NA1SS. I have
made 3 of my previous 6 ISS QSOs with only 5 watts, and
one of those using a long telescoping whip on an HT
instead of a directional antenna, so I know anything is
possible.
I e-mailed Christy KB6LTY, who lives near Victorville,
to see if she was part of that group that you said may
have made the QSO before you. She's involved with Scouts
there, and is occasionally on the satellites, so it would
have been a real treat if that was the case. I heard
something around 1814-1815 UTC, but the audio was not
readable at my station.
Congratulations to ALL who were successful in making a QSO
with the ISS during Field Day. 73!

Yes - It was one of Christy's kids that made a contact Saturday! I already
forwarded to her the instructions for obtaining a QSL card from the contact.
I just found it amusing that of the first three or so contacts on that pass,
one
was made with a mobile rig at high power, and you and I chose 5W or less
to accomplish the exact same thing ...
Long live workin' the birds with low power!
