One thing I might add: often I encounter stations spending a lot of time
trying to find themselves on the transponder. I suspect they are trying
to calibrate their SatPC32/MacDoppler/gpredict. Sadly, they spend so
much time doing so that they miss out on the precious transponder time.
Ditting/hola/test-test-test without sending a callsign doesn't even
make for a good SWL report.
I would suggest stations NOT try using computer control and enjoy the
transponder with manual control.
Chances are if you are not hearing your own downlink on AO-73, you
probably either have a poor antenna/feedline OR (more likely) you are
not listening in the correct corresponding downlink frequency for your
uplink frequency into the transponder. AO-73 is VERY easy to hear!
