Hi again Mike, in my rush to get the beacon info off to you I left out another interesting
bit of info. Prior to the normal telemetry frame I received the following:00DP0COM-COMPASS-1-012345-COMPASS-1
This was 38 seconds after I sent the beacon test command. Alan, ZL2BX

Bob, W1ICW:
Just heard the following telemetry from Compass: COMPASS FF0874000000002100009000FF
I just worked the 16:43 pass ( only 8 degrees elevation ) and was able
to successfully upload all four commands twice with confirmation both
times. Keep the faith, baby! 73 de Bob W1ICW
