Hello there, I am trying to wire a Turner desk mic (with a Midland label), to a Teaberry Big T. The mic is essentially a Turner Plus 3, but what I believe is different is that it is not switchable between relay/electronic switching. I have tried what I thought is the right wire/pin configuration and it will key down and "squawk" (terrible), but no receive audio. Radio is 4 pin, and does work with the stock hand mic. Desk mic is 4 wire with the typical black, white, red, shield. It is like new, and I don't see any reason that it doesn't work, but may not be compatible with this radio?? Any thoughts would be greatly appreciated
