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?
