trc441/mic

[doctor]

I have a trc 441 and the mic has a control on it for volume on the radio, most say it is an amplified mic, although no battery in it. Anyhow when I turn it up it has a loud squeal feedback in the radio when I talk,, so how do I get rid of the feedback..a resistor on the audio?, all mic wiring's show white as the audio..this has 2 white wires...the mic is a realistic dynamic mic for the radio...any help let us know, appreciate it

Can you get the mic model number off the back of the mic and post it? That would be a big help in figuring out what's up with the color codes.
