help with cobra mic wireing

[itsonlysir]

i have looked and looked for this answer on the net ,,, haven't found it yet , figured id ask here ..

i have a cobra mic that was given to me ,, its alot thinner then the antistatic i have , but anyways the only thing it says on the back of the mic is

dynamic microphone
1mp. 500ohm
made in korea

the wires in side are red , purple , black , and a bare wire . i have seen meny posts that say this

1- shield
2-audio
3-transmit
4-receive

im guessing shield is the bare wire , but the rest i dont know what they are to put them where they go . it is going to be hooked to a 4 pic jack for a cobra radio..

thanks for any help..

cobra mic


red is audio.
black is ground
the purple should be transmit (or pin 3 on a cobra 4 pin)

let me know if that works.

Didn't see any schematic that shows a purple wire.
Here is the link to CBTricks and the Cobra mic:
