Trying to find some mic wiring information on this 6 pin radio. I'm hoping it's the same as Magnum 6 pin but since one of the pins is hot I'm not plugging a Magnum or RCI mic in until after I know for sure. Does anyone also know which trimmer pot will adjust the AM carrier? I will open up the radio here when I get a day off work and see if the board is labeled, that would make it easy.
