PTT via front panel microphone connector is not working.
I normally use a footswitch connected to the rear panel jack for PTT. However, while getting ready to take my FLEX-6700 to a hamfest for a demo, I connected the FHM-1 hand mic that came with the radio & found that PTT would not work. An ohmmeter check of the microphone showed that it was okay. I did a reset to factory defaults & that did not help.
Radio: FLEX-6700, s/n 1713-3011-6700-4673
HW Version: v126.96.36.199
