880 Mic rewire help

[psionx]

Good mornings/afternoon all.
I have a Astatic Red Devil 104E mic that I'm trying to rewire to a Uniden Bearcat 880.

The Astatic I have is 4 pin 6 wires.
White Audio
Shield Ground
Blue Common (switching)
Red TX
Black RX
Yellow Receive ground

The bearcat is a 6 pin but only 4 wired on mic
Yellow Audio hot
Black RX
Red TX
Shield

from searches this is what I have found and im not even sure it's correct

Could anyone help me figure this out please I would greatly appreciate so much.... I have no more hair left to pull out and wiring is do not my strong point

Thanks

There is a 4 to 6 pin adapter you can get for that radio.

On the Uniden Ground is Common - Looks like on the astatic that there are 3 grounds. They could all be tied together.
microphone shield and Rx ground should be common

Uniden needs TX RX and MIcrophone and the others are grounds- you can ohm them out and see if they are seperate
or tied together.

Sorry for the late replies. I did have a that 4 to six pin adapter around but couldn't find it and locally to me there was non in stock😔

I wired it up and figured it out from KEWB-N1EXA post and with some extra digging around I had it work. I did come across a terrible RF squeal after and had to have the mic gain down next to nothing. Grabbing the mic cord eliminates the squeal.

After some research I decided to do the battery eliminate mod on the mic and use the radios built in power for the RD104E mic. I can say this thing works flawlessly and zero mic Squeal and excellent audio. Thanks for the feedback guys👍🏻

Your not the first Guy to find putting a power mic on the 980 SSB Is a challenge. Its been posted here before that it gives a
squeal or feedback due to the gain. Looks like you found a Good Workaround for the Power Mic.
