CM200D Transmit Audio Output

[b18c_ej8]

Any easy way to tap Tx/Microphone audio to feed to a recorder on a CM200D?

I tried to connect pin 5 on the accessory connector, but no dice. Also tried Pin 2 as on previous generation radios was parallel to the front mic jack but that doesn't work either.

Really trying to avoid going inside the radio, but it's looking like that's my only option to get this thing to record transmit audio.

I’ve been told they should be the same as the Waris (CDM) series radios. Also look up “Cable 62” by eBay user mre1032. That is an easy way to accomplish what you are trying too.

It is not the same as the 16 pin (ie CM200) radios even though I’ve seen Motorola supply the same accessory cables for both families of radios.

I misunderstood. You want to get the audio you are transmitting? You would have to add a tap into the Mic. There are some companies that make a box that will do it for like interfacing with an intercom system. I’ll see if I can find a part.

Yes, Rx audio is easy, using the discriminator audio pin on the accessory connector. Need to also feed the mic audio into the recorder as well.

So the ASTRO 25 or later mobiles in a dual head setup you can have the transmit audio of one head feed through the speaker of another. I think Sigtronics used to have the adapter you are looking for since it sits inline of the microphone.

This will at least give you a terminal block to pull audio from:

That's actually the way I'm heading. I have a similar setup on the bench right now. Thanks!

Just a quick update for future reference:

I ended up building my own splitter with two 8 pin surface mount phone blocks and a short 8 wire satin line cord.

Line cord plugged into the mic jack of the radio, then into block 1.

8 pin blocks were wired pin-to-pin via a piece of cat5.

Microphone was plugged into 2nd block.

Grabbed microphone/Tx audio out of one of the blocks and fed into the recorder's radio interface. Will need to adjust vox sensitivity in the recorder settings due to mic audio always being present, which results in recording room audio intermittently, but customer is back up & running for now.
