Hi!
After working FO29 & AO27 in the last hour, I'm back for
the passes on these birds in the next 45 minutes. It
is about 96F/36C, cloudy & humid. My glasses fogged up
when I got out of my car a little while ago.
Hope to work you on these upcoming passes... 73!

Heard you FB here in FN34 Patrick, but couldn't get the old computer
booted up fast enough to work you on FO-29.

Thank you to all of the hams that helped to make the ARRL Teachers'
Institute II a success. I had 8 teachers this past week at the Dayton
Amateur Radio Assoc. club house learning how to set up and operate a
satellite station, and by the first part of Day 3 all 8 had made their
first satellite qso! By the week's end many had made multiple contacts
with the satellite community. Thank you for your patience and
stick-with-it-ness with this group. They are very excited to get home and
set up their station, and even more excited to share satellites with their
students.

While working with the 8 teachers at Teachers' Institute II, I had a
variety of computer operating systems. We had some odd behavior with the
Win7 machines, but I am not sure if this was a fluke or a pattern.
We were using SatPC32 v12.8b with the SAEBRTrackBox setting in the
software, and the students with issues were running Win7. The G5500's did
not always respond as expected. For example, if we commanded it to move to
45 degrees elevation, it would, but if we manually entered 179 degrees it
would drop down to about 25 degrees. The fix seemed to be to set the
turning point of azim rotor under the 'Rotor Setup" to S instead of N. I
am running v12.8a and have not trouble with the exact same set up and I am
set to 'N".
Has anyone else experienced this? In my trouble shooting, I believe I was
able to trace it back to the computers/software. Any thoughts?
Thanks in advance.
Matt, N8MS

OK, that's identical to the Fox Delta ST1 kit.
Have you calibrated it?
The procedure is here, on the Fox Delta page:

Hi all,
Looking to optimize my portable antenna setup for best performance.
I've got an Elk dual band and an Elk 8 el uhf log periodic for
uplink/downlink. Gain figures (from Elk) are 7db give or take for both
bands and 8db for the 8el uhf
How should these be mounted to minimize interaction with the ground,
each other and the tripod for the best results?
73 es have fun,
Norm

The key to success on a busy channel is short packets:
> N3YKF-3>APTT4,ARISS,IS:/131918z2901.30N/08210.41W>288/000/n3ykf
mobile!/A=000121!wgO!
There are 41 bytes in that packet that are of no value in this application.
1) Remove the path "IS" (is 7 bytes in the actual protocol) and it is not
valie anyway for APRS
2) A time stamp is usually not needed, since APRS is always LIVE, it is
valid the instant it is reecived
3) No need to repeat your call in the packet since it is in the callsign field
4) No need to say "mobile" because you are using ths symbol for a car anyway
5) When going through the iss at 7,000,000 feet high there is not much value
in reporting your altitude as 121 feet.
6) When making a thousand mile contact the PRECISE position data in the
!wgO! format to 6 inches is not needed
7) Use the !DDMM.mmN/DDDMM.mmW>... format without the time stamp.
8) Make sure your TXD is 150 or 200 ms instead of te default.
That should cut your packet timeto HALF or more and double your chance of
success.

It would have been nice to work you. I was using my normal portable
SSB satellite setup - two FT-817NDs, Elk log periodic. Hopefully we
can hook up on FO-29 or some other satellite.

Heard you on the FO-29 pass around 17:20 utc today (Saturday). Good signal
on both CW and SSB. I tried calling you on both CW and SSB but no
luck. Thought you might want to know that your are getting into the sat.
