    Hi, I have an Icom IC-2820 which works fine with my hands free boom mic in the car. A simple up down button and PTT.However when I plug in the supplied fist mic with DTMF keys it lights up, the LEDs function but the radio does nothing. I've tried a replacement mic and cables with the same result. Question is has anyone else found this and what was the solution. Am I missing a simple menu setting. The book has nothing listed.

    Maybe a stupid question, but did you inadvertently lock the radio? If you have the lock key showing on the right side of screen you either need to press and hold the power button on the control head, or plug the HM-133 in and press and hold the VFO/Lock button til it unlocks.

    Otherwise I would suspect a bad cable or problem in the mic connector.

    Thanks for the reply. No it’s not locked. The mic connector works fine with the boom mic just not with either of the fist mics. Very strange.
