Gr300 M120 How to convert to Repeater Mode

Post by mirage »

I Have a GR300 that someone here programmed the M120's as a standard radio. How do I get it to work back in the repeater mode. Right now it says it has to be a 16ch radio only.
Thanks for any help Doug

By default in m120 you find COR in Pin 8, on acc connector, need no special programming, if you dont have the pinouts
make one
TX RX
pin 2 pin 11 Audio
pin 3 pin 8 COR
pin 7 pin7 GRND
if you dont have RICK you can add from pin 8 to pin 7 one 15v 33uF, or 47 uF, depennding how much hang time need,

Ok maybe I was not the clearest the radio will not program using the GR300 software as a repeater radio so I do not have to use a rick the program prompts me to have a 16 channel radio.
