[aprssig] AO-51 is in APRS packet mode again

For those APRS folks wanting to experiment with
9600 baud satellite APRS using their D7 or D700,
the ECHO satellite AO-51 is back in APRS digipeater
mode. Freqs are 435.150 +/- 10 KHz doppler and
uplink is 145.86 using the path VIA PACB-1
Just set your APRS D7 or D700 APRS menu item
to 9600 baud instead of 1200 baud and change
yoru path to VIA PACB-1 and the uplink should
work just fine. The problem is the weak downlink
you will only hear a few times a day in the middle
of the two best passes of the day. The rest of
the time, you probably need a better antenna.
But if we have IGates with good antennas brining
the dowlink into the APRS Internet system, then
we have most of what we want. A Satellite RECEIVE
system for APRS trackers in the wilderness that
can be captured into FINDU.
If you have a UHF beam (doesnt need to be a big one,
just a hand-held 7 elemet ARROW will do very well.
In fact, about 5 elements should do well...

OOPS. I just worked AO-51. It was back up in PACSAT mode last pass. The
digi is also on....

>> Hi Jamie,
>> One of the options is to use the programs for a single task (only).
>> Use SatPc for doppler control,
>> Use unitrac for the rotor, and use WISP only for initially setting up the

>> When the sat is AOS just run MSPE for your TNC. Don`t start GSC after the
