The COR output on an M120 is an open collector thru a transistor to ground,
therefore you will not see any voltage change unless you supply a +5 or +12
voltage through a 10K or 100K to this pin. Then when the collector switches to
ground it will pull down the voltage on the end of the resistor to ground. The
collector is protected by a 27 volt zener.

Thanks. I placed a pull up resistor between pin 8 and V+. Do you know if the M120 or GM300 will go down to the 434/439 mhz split?
