Just curious.  Does PCSAT-1 only tx on .390 when over North America etc,
quiet at other times, or is it active world wide on that frequency?
Only ask, as it may explain some "odd" noises heard in the past in what
is our SSB segment of the UK/EU 2m band.

> 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) No operations after dark!
> Enjoy PCSAT-1 and APRS! Make contacts, QSO, enjoy!
