[amsat-bb] Repeater interference on AO-92

[Stephen DeVience]

I listened to that Satnogs recording again, and I hear a single beep
courtesy tone between transmissions from each person, so I think it's a
repeater. It has some points where the repeater conversation stops and then
appears to bring up the satellite again, so I would think it needs to match
the tone. Maybe someone here can better explain how the Fox tone squelch
works, for example how long it stays on after hearing a tone.

The repeater that I suspect has echolink, so maybe I can get on it during a
pass and get a recording.
