[amsat-bb] Help Needed: GNU Radio + FoxTelem

     Just wanted to let you know the pulseaudio/pavucontrol method 
worked like a charm.  So I *think* I've got everything sorted here for 
GNU Radio + FoxTelem for the 1948-ish Pass over Eastern US. Only 
variation is I'm using a standard audio sink instead of null sink.

One day I'll try to sort the IQ stream method instead of audio, but i'll 
shelve that one for now.

thanks a bunch!
