Mic PTT no longer works, among other strange things

The Flex supplied FHM-1 mic push to talk no longer works, it stopped working today. I tried different mic's and get the same result; no switch to TX when I press the mic PTT button.. Here is the strange thing, if I reboot the radio by removing and reconnecting power, and turn it on, and then restart SmartSDR, the radio comes up in xmit mode with the front panel led showing red. I see signals on the panadapter, and can talk into the mic and see that I am transmitting audio (without pressing the PTT button on the mic). MOX shows to be off. I can correct this by killing SmartSDR and powering down the radio using the front panel switch. Then restarting the radio using the panel PB and starting PowerSDR, all seems normal again, EXCEPT the mic PTT still doesn't work. Guess I'm stuck with VOX (which I don't like) and/or CW mode until this gets fixed. What is going on here? any ideas?

    I checked the back panel PTT, and it is working correctly, but not the mic PTT. I checked the mic PTT connection with my ohm meter to be certain it is making closure, and it is! This was working correctly until today. Now it is NOT.

    In this case only one thing i hope - unsoldered or mechanical defect in the front mic connector of the radio. I have no schematic diagram, but on logic base both circuits - on front and on rear in parrellel

    Verify its the mic first. If you disconnect the mic from the front panel does the problem still persist? Greg

    Greg, Click on "Community" in the upper left hand corner. Then click on "Zendesk" on the right hand column about half way down. That takes you to the HelpDesk. Then click on the "Submit a Request" That will lead you on your way.

    Well, today the mic PTT started working again. This worries me. I have not yet submitted a "Request". Should I? I think I'll wait until something else breaks!
