[amsat-bb] AO-51 SSB/FM mode

Over the past few days there are more and more people getting on. In a way, it sounds like a traditional linear transponder, with some people exactly on frequency, and most within a 100 Hz or so. It does allow people to break in more easily than the FM mode.

One effect becoming more apparent is deep fading in the audio. I am wondering if this is caused by people outside the passband, but near enough to drive down the gain on the uplink?
