1 Mic for 2 Radios

[CSL126]

Hey guys, I have a quick question for you. I’m not sure if what I’m asking is possible, but I’m just trying to consolidate some equipment and free up some space.

I have a connect systems 800d DMR mobile and an ICOM 5100. Both mics use the RJ-45 type input. I almost exclusively use the mic for the PTT button. I control the radios from the controls on the radios themselves. If I’m only using one radio at a time, would an RJ-45 splitter enable me to utilize one mic for both radios? If not, does anyone have a suggestion? I’ve got a nice setup in my GMC, but it would be better if I could lose one of the mics.

Thanks in advance for your help!

No, you can’t use a splitter. IF both mics use the same pinout and type, you could use an A/B style switch box. But you would have to confirm that both radios can use one of microphone types (e.g. both are compatible with each other). Unlike ethernet in an RJ-45 plug, the wiring of these mics is up to each manufacturer.

The MFJ-1261 is a 1 mic to two radio switch. Look very carefully at the description and specifications to make sure it will work with both of your radios.

It may not work because those radios probably require different types of mic elements. I know I can't use the same mic on my Yaesu radios that I use on my iCom.
