[amsat-bb] Satellite packet question/answer

Hi Mike,

For the most part, the only bird currently running the "store and
forward" pacsat PBBS system is AO-51.   It's up and operational,
depending on the schedule, at 9600 BPS.  I find the "challenging" part
is the L-band uplink--even with around 25 watts at the antenna, my
house and TREES get in the way and make the uplink difficult.   Good
old Wisp still works with this satellite.  Few messages are actually
being passed these days.  The store/forward packet system on AO-51 is
used a good bit by the command stations for telemetry downloading,

GO-32 hasn't been running its 9600 BPS packet system in months---it
has been sending telemetry at 30 sec intervals off and on lately.

I think that's it at the moment...

"Does anyone do Satellite packet? If so what kind of TNC is needed. Can a
Kam KPC-3+ used for VHF packet work?  or do you need a different TNC.?
Are there many birds that forward messages around the globe like years
ago when pacsats were famous?
