Quick question: is there some way to add squelch to SSB? Maybe to replace one of the buttons I don't use or that is whited out?
The static is distracting (and even a bit irritating) when I try to use SSB rigs that lack it. (It's a personal thing - some sounds I find soothing, but that is one that does the opposite.) I have an external noise filter for another radio to solve the problem, but would rather not do that to the softrock.
I'm not sure how the squelch for FM works (my guess is that it detects the quietening of the audio), although from my observations, software like GQRX seems to do the opposite (detects increases in audio after the filter).
You might contact the author of gqrx (Alexandru Csete) or their
website (gqrx.dk)... the squelch setup for that program is
effective and easy to set up (based on signal strength by setting
the squelch baseline above the noise floor, and muting audio until
a signal exceeding that baseline passes through the filter). You
can get the source code from their website, and that might help.
GQRX is good for receiving (I use it
with a NESDR Smart dongle for different tasks), but I prefer Quisk
for my softrock. GQRX does have squelch for any of the modes.

Quisk does not currently have squelch for SSB. I do not know an
algorithm for it, so it would help if someone could point me in
the right direction.
