Batboard

Hello,

My 1st post

I have a AARMN4025B Mic from a Motorola CDM750, that I would like to use on my Icom V8000 2 meter ham radio. The Icom Mic is rather fragile.

I'm looking for the pin out assignments to the Mic connector (RJ45).

Does anybody have it?

Thanks

The CDM MIC pin-outs are on batlabs.com in the model specific section.

The Motorola mobile mic's are way different than the ICOM mics. The Motorola mobile mics have a built-in preamp powered by a bias voltage provided by the mobile. Seems the CDM series are a little different, but still have the amplifier built-in and different output levels.

The ICOM radios do not have the bias, and use a lowlevel mic element, so are not compatable. ICOM would not provide a schematic or parts for the mic(s).

And yes, the ICOM mics are J U N K...
ICOM has a more rugged mic, HM150, that we ordered, but it is not here yet for evalulation.

pinouts for some other brands, limmited information on some of the pins:
