PCSAT-1 recovered!

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
a day!

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  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

> 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

> 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
