PCSAT-1 responded to all RESTORE commands on the 1320Z pass this
On the next pass (now in full sun), she remembered it all and
was fully operational (though the transmitters were again cross
connected meaning that relay had dropped out in the dark over
Europe. But we set the relay again and she should be fine.
PLEASE limit all operations to DAYLIGHT hours only, and PCSAT-1
should be good for the next few weeks. Also, on the same
145.825, you should also hear ANDE and ARISS. That's 18 passes
Please see downlink packets on http://pcsat.aprs.org
As long as the callsign "PCSAT-1" is appearing, then she is
holding up. If W3ADO-1 appears, then she has lost it again...
PCSAT-11 downlink is on 144.39 over North America so all mobiles
on the normal APRS channel can be alerted when it is in view...

> 145.825 ISS APRS digipeater
> 145.825 PCSAT-1 (recovery expected 3 Nov)
> 145.825 ANDE-1 (re-entry expected next month)
> 435.225 GO-32 +/- 10 KHz and 9600 baud
> 435.300 AO-51 *FM Voice* +/- 10 KHz
> 436.795 SO-50 *FM Voice* +/- 10 KHz
> 436.795 AO-27 *FM Voice* +/- 10 KHz
> As you can see, there will be over 40 passes per day with 18
> the 1200 baud satellites, 6 per day for the 9600 baud GO32 and
> 18 for the voice birds. All 1200 baud pass times are between
> about 6 AM to 1800 local sun time in the Northern Hemisphere.
> GO-32 and AO-51 voice birds are in the morning and evening,

> The packet path on 145.825 is VIA ARISS for all three
> satellites. The path for GO-32 is VIA 4XTECH and uses two
> different uplinks: 145.85 for APRS software and messages.
> 145.93 for all Mic-E, D7 and D700 radios.
> That's more than one pass per hour on 145.825. Lots of

> For APRS birds:
> For AMSAT birds:
> For many of these satellites, you don't even need a tracking

> The best antenna is a 19.5" whip in the center of your roof.
> dBi gain on the 2m uplink and almost 8 dBi gain for the very
> weak UHF downlink (above 25 degrees)...
> Watch for special event info.
