Doug,
That makes sense. So,   I would guess that sq=0 means that it is off, 
while sq=1 would be on.  If that is the case, perhaps the setting 
already set in sqlevel=  would have some effect.  i'd be interested in 
hearing what your friend tells you.

I usually run the FSK filter at 250 hz, which is the lowest setting, and 
along with least amount of audio input to the sound card to give good 
print, I can limit the amount of garbage text.   Using the squelch would 
probably be a nice addition.
