Batboard

I believe that Motorola makes a accessory that has a 2nd mic and speaker that connects to the back of the cdm series radio. I am looking for the part number for that. Thanks for the help.

any help would be appreciated

You can use just about any mic you want. bear in mind that like the front panel connection, the rear aux mic
connection will have the bias voltage there. If the mic your going to use does not require the bias voltage,
don't forget to cap couple the connection to the radio.

As for the speaker connection, just about any speaker will work. You don't have to buy the gold plated stuff from
Motorola. Just try to match the same impedance speaker. I believe they are 8 Ohms, but could be wrong.
