Is it a 4 wire mic cord? I recently had one of those but I can't remember the wire colors. I assume it's wired for electronic & not relay. They came both ways & ea could easily be adapted. What about the element? Have you tried the mic on another 4 pin cobra type radio (dynamic not condenser)? The "3 black, 4 red" has me wondering at the moment. I thought black on a turner was always the rcv wire which would be pin 4. Maybe that's not the case with that mic? And red is normally the common on turners, but again, maybe not on that mic, esp since if it's a 4 wire (3 conductors + shield) cord it has no common. Usually blue is tx (pin 3) on a turner but again, maybe not on that old mic. Red just doesn't sound right for rcv but I'm prolly mistaken. Another possibility is incorrect internal wiring. That mic came 2 different ways, a J & a JM I believe & I think the difference was setup for E or R switching, but, either one could be easily converted inside for the ither so possibly someone converted it but got it partially wrong. I believe the wiring & schematic are readily available online. What happened to cbtricks? When did they take their site down? Any word I'd coming back? Where is a CD rom available from? I'll look for the wiring... But you need to test that mic on another radio to confirm the mic problem.
