For the afternoon pass 21:17u @ 52 Deg, I used Dave's method and NOT try
to match up signals. Use a program that decodes all of the signals and
try to reply to as many as I could. With some practice, that should
work out better. I don't know if Glenn copied me or not. He was the
only satellite CQ I saw.
As for power: I can barely see my signal using my di-pole. When I
used 85 watts 70% ALC into a 1/2 wave vertical, (10m Ringo) I was able
to turn on the FM transmitter and saw a good clean, 21 IMD, signal on
the down-link. I have no idea what it looked like for the terrestrial
I did not have to wait for the telemetry to turn on the FM
transmitter, and I did not splatter across the waterfall of the down-link.
More practice coming.
