So I'm trying to set up a cdm 1550 repeater. I've got one of the accessory port cables. I've done some research and everyone seems to have good luck with them. Duplex repeater Interface cable Motorola radio CDM750 M1225 CM300 GM300 CDM1550 | eBay
When I connected mine, I had to program pin 8 for the COS, which seems to be working. When either radio receives a signal it will key the other radio. My problem is that I have no audio between radios. From what I've researched, the audio pins are not programmable. Is there something in the setup that I don't have correct? Any other ideas would be greatly appreciated.
