i was gifted this radio without a mic plug. The person I got it from says the plug he put in there is good, but he took it apart a long time ago and said he couldn’t figure out how to get it wired back together and guess what, neither can I. After messing with this all morning I have gotten as far as discovering that the yellow wire and the blue wire must be grounded to get receive on the radio. It has great receive so long as both these wires are grounded. I have two more wires coming off the dynamike switch, a black and a white. All 4 wires total is in this picture. I have tried every different combination to try to get this thing going and I’m just giving up maybe one of you guys know which wire goes to which pin .
