PCSAT-1 has been recovered as it entered better sun angles.

PCSAT-1 should remain NORMAL OPS for the next few weeks until it
experiences an overload and resets.  Then we lose it till
December.  So we ask that all users please adhere to these
fundamental principles:

1) No unattended operations
2) No connections to or through PCSAT-1
3) UI digipeating and APRS packets only typically at 1 minute
rates or so
4) Watch pcsat.aprs.org for live activity
5) Use the path of VIA PCSAT-1 or VIA ARISS
6) Minimize all packets after dark!

Enjoy PCSAT-1 and APRS! Make contacts, QSO, enjoy!

Just remember that ACKS are pretty useless and only add QRM to
the channel.
So do not expect ACKS via the satellite.  If you see your
outgoing packet digipeated by PCSAT-1 a few times then you
should ASSUME that the other person got it and delete it
yourself.  By the same token, if someone sends you a message,
then ANSWER him in kind, so that he knows you got it.

See web page PCSAT.APRS.ORG  or Google for PCSAT.
