[amsat-bb] PSAT downlink

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 W4UOO
