Hello All,
Has anyone got the PG_AEA program to work? I tried to upload about 144k file
and it exhibits some problems. I am using it on com2 at 19200.
Symptoms:
1. It sends two bytes of the 144k *.out file and then says "waiting for
final handshake". The satellite gives back a -7 (No PFH) error.
2. The program immediately starts to connect to the satellite. If it does
not connect (I get a disconnect message) than it does not do anything.
I found out that F8 and F9 cause status displays when pressed. It stays
in disconnected mode even when it gets open commands and there are files
to upload. I have to exit and re-run the program.
A general comment is that I wish that there was more information displayed.
I do not like programs that run without showing what the satellite is
beaconing and what the program was doing.

SB SAREX @ AMSAT $STS-58.024
SAREX Keps & Update: 10/26/93
The extremely successful school group contacts have cleared three school
group backup passes for possible general QSO opportunities. While the
SAREX Working Group cannot fully guarantee availability, there is a high
probability that the STS-58 crew will be ready and waiting to take general
calls over the continental U.S. on these passes. These opportunities
include passes on orbit 145 at MET 9 days 0 hours 6 minutes (10/27 at
14:59 UTC), orbit 178 at MET 11 days 1 hour 42 minutes (10/29 at 16:35 UTC)
and orbit 192 at MET 11 days 22 hours and 29 minutes (10/30 at 13:22 UTC).
School group highlights today include two horizon-to-horizon opportunities
for the Lycee Gaston Febus school in Pau, France, where 15 questions were
answered, and the St. Barnabas Episcopal School in Houston, Texas where 12
questions were answered. During the French contact, one student asked
Shuttle pilot Rick Searfoss, KC5CKM, if the crew could see satellites from
space. Rick explained that indeed they could. He stated that during this
mission they have had visual sightings of the Russian Space Station MIR and
NASA's Gamma Ray Observatory. The Gamma Ray Observatory was built by TRW
for the NASA Goddard Space Flight Center and was lofted into orbit on the
STS-37 mission. (STS-37 was the first mission with an entire crew of ham
radio operators--Ken Cameron, Jay Apt, Linda Godwin, Steve Nagel & Jerry
Ross).
Hams across the U.S. and around the world have been working the Shuttle
Columbia on both voice and packet. This morning's voice pass over the U.S.
had both Bill McArthur, KC5ACR and Marty Fettman, KC5AXA, firing off
callsigns in classic DX pileup style. General QSO operations thus far can
be summed up with one word---outstanding. The SAREX team wishes all of you
the best of luck in your endeavor to work the shuttle.
Gil Carman of the Johnson Space Center compared a recent state vector to
element set GSFC-025 and found only a two second difference. Therefore,
there will be no new SAREX element set released today. GSFC-025, generated
by Ron Parise, WA4SIR is provided below for those who did not receive it
yesterday.

I have worked them from my mobile, which admitedly high power at 100 watts.
I was using a 5/8th vertical. I didn't need the power, but being the rig is a
commercial unit, I am locked in at that power level. The received signal strength
was several microvolts.

Myself, I've been able to receive SAREX packets from almost every
pass with a DJ-580 and a dipole on my roof. But I haven't been
able to connect, no matter how much I try, even when nobody else
is connected. (Being in a small country surrounded by ocean and
desert helps here....) If any of you have made a successful QSO,
could you tell me what your setup was, and how much power was
necessary?
