If you mean a squelch operated relay, it was an option on the base
units. You can hear that relay trip hundreds of feet away from the unit.
If you mean an internal (to the drawer unit) squelch, I think there may
have been one, but it is really easy to build - just use a 10K pot with
the ends tied to Vol-SQ hi and low respectively, and the center tied to
the point marked Squelch Arm. There is a company that sells plug in
boards for the M-II mobile (or base, I guess) that has both the squelch
and audio pots mounted. See:
I haven't used that module myself. I prefer multi-turn pots in the
squelch circuit for additional control (accuracy).

Is a squelch circuit an option on a GE Mastr II?
Is it a module?
Is there a way to build one?
