Dear
Greetings fromVU2.
I am trying to change mic from Icom to Motorola PTT Mic with out DTMF. I need only PTT for my ICOM IC2200H
My PTT mic is no functional. I bought new a switch (not original) and replaced it. It worked for a while and failed. Spares are hard to get in vu land. So I got one used Motorola Mic with PTT switch. No DTMF. I need o to work with PTT only..
Please help me to pin point info to rewire the RJ 45 in Motorola.
Regards

You have to register only.

Hello!
If I were you, I would try to repair the original Icom microphone. I am attaching the Service Manual, the PTT button is a simple SMD microswitch, it is not a big deal to repair. I would need a model number for the Motorola microphone, based on that you can find a pinout, but in my opinion this would be the final solution.
