[amsat-bb] PSAT downlink

[Mike Rupprecht]

Mike,

the PSK31 transponder is always in AUTO mode, listening for a PSK31 signal
at 28.120 MHz.

Yes, PSK31 must be detected (or w3ado beacon must TX) before 70cm downlink
transmits.

The diagonal moving stations were probably just terrestrial QSO' s .

So I was able to copy Psat  435 mhz downlink today...nice !

Copying the beacon with digipan was quite easy. Watching the stations move
diagonally across the waterfall was an interesting Display of the Doppler on
the uplink. Watching the satellite today transmit then cease to transmit
then transmit again raises one question. 

Does someone have to be transmitting to the input of the satellite on 28MHz
for the beacon / fm 435 MHz downlink to be active ?

Thanks,
Mike
