I know that this is an old thread but I was looking for some help, I set up this repeater and everything works like I want, other than the ID-O_Matic, I plugged it into the radios and I can hear the Morse id and the beep but once I plug it in, there is no audio for a user being transmitted. Once I unplug the ID-O-Matic, I can hear the other person just fine. I would appreciate any help. TIA!
