The COR output on an M120 is an open collector thru a transistor to ground,

Pins 4, 6, 8 and I think 12 on the M-120 and GM-300 radios are
programmable for several options. When in the programming screen,
under mode options (showing frequency and PL's) I think you can press
F9 which is "accessory connector" or something to that sort. This
will let you select the pins
What is the voltage when the receiver is squelched? It is likely
that it is around 10 volts. You can invert this if necessary with a
transistor and 2 resistors
