    What version was you running before 3.18?

    power down the radio unplug DC power wait about 5-10 minutes  then power the radio up and see if it is still having issues, if it is then try a HARD RESET.
    This will do a Soft Reset by removing DC Power and then a Hard reset by holding the Power button until the button turns white I think.
    This will erase your profiles so you may want to export them before doing the Hard reset.

    Bill, not sure I believe it was 3.17... I am using Heil Pro6 head set as my default  and did the Hard Reset and put all the value's back (TX settings and Mic default). I even tried the hand mic but got the same result. Funny the TUNE works fine 10W low SWR, so it must be on a separate TX than the PTT.

    I still don't fully understand what is wrong? is it not transmitting? PTT does not work. How are you keying the radio? I use Vox for my headset. Are you using the correct cable for the Pro6 headset? to the flex?

    Bill, the only TX I can do is TUNE, it will transmit when I tune up with 10 Watts. After that I try to TX with 100W and get nothing. I switched mic's and nothing! I am using the same cables I have been using for the last 3 years.

    Did you check the Power slider?  I had a similar situation.  I then slid the Tune power slider up to 100 watts and it transmitted 100 watts on Tune.  Then noticed the Power slider was on Zero watts.   For some reason it had defaulted to zero.   I assume your PTT is lighting the Red LED on the radio.

    Have you tried clicking on the MOX button in SmartSDR?  If the MOX button still works, it could point to a problem with the PTT switch, cable or jack.  If not, then it would indicate a configuration problem of some sort.

    I had the same issue recently with my 6400M and the stock Flex hand mic. All of a sudden during a QSO the rig would not go into TX. The mico switch in the microphone for PTT broke, It is just a very cheap tiny plastic switch. I replaced it with one from a Motorola mic. It was not a exact fit but it does work for now.
