channel reciever
No, I am not certain. I had someone program the
radios for ham freq.
That is kind of what I was wondering. The manual
shows the 8 channel
pin 8 is COR and the 16 channel pin 8
of dragons...

Sorry to bring this back up the pull up resistor did not start the
COR. Looking at the schematic the MMBT3904 NPN is connected to pin 8
from this a 10k resistor takes it to the MC68xxx processor. Best guess
? programming? or NPN transistor.
Thanks,
Henry

OK! thanks Russ, that makes perfect sense. I will try that this evening.

Hello Henry.
I believe the COS on the GM300 is active LO. Open collector.. Try using
something like a 10K pull up resistor
