Ok guys, I'm stumped

I have 3 Shure mikes that I can't get to modulate on a 4 pin configuration.

Each has a white, red, green, and black, no shield wire. Two of them I managed to get transmit in three different ways, but the third squealed in tx, all 3 would not produce audio.

Before pulling the rest of my hair out, my thought was the black wire may be rx and there is no shield. Maybe I would have to go into the mike and switch the black over to ground.

Thx.

The following is from Ken Thouey's Yellow Book.



"If you have 4 wires: check between the shield and each unidentified wires to see which has continuity in recieve & which has continunity in transmit. (When you have 4 wires & find niether unidentified wires connect to ground; but the do connect to each other -- then you have a relay switching mic.)!

If there are 5 wires you have to experiment to see which wires connect tfor recieve and which wires connect together for transmit. The wire that connects to each other of the others (one in recieve & one in transmit) is "common,"the others are recieve and transmit."

I guess it didn't help.

    Seems to be dead on the radio lately. I don't know if the conditions are horrible, or more likely my weak antennas. I may head up in the mountains on Wednesday and see if reception / transmission is improved.
