[amsat-bb] FoxTelem Program & RTL820T Dongles

[Burns Fisher]

Doug,  Do you mean you are using a FunCube Dongle or something and having
FoxTelem decode the RF (as opposed to feeding it audio).  You can turn off
the audio entirely by clicking on tab on the input section (just above the
audio/FFT display) that says "Silence Audio".  If that tab says "Monitor
Audio" then it is already turned off.  You can also monitor the audio and
have it squelch when there is no telemetry being decoded using a checkbox
on the side (Squelch when no telemetry" or something like that).  If you
mean to use this to listen to QSOs, remember that while you might be able
to hear them sometimes, the ear is incredibly sensitive, so you might be
squelching something you could actually hear and understand.
