I don't pretend to be a RF guru, but your problem sounds to me to be caused by
either a shorted antenna cable or a bad connection at the radio end of the RF
cable. I suggest you check the RF power output with a Watt-meter and/or having
the cable checked wit a SWR-meter. Borrow both instruments from the local radio
amateur league or the avionics shop.

Examine your schematics. Replace any or all switches in the microphone
circuit. If you have a push to talk relay, clean the contacts, if that works
replace the relay as the trouble will come back soon. This is the easy end
of troubleshooting.

Finn,
Thank you very much for the Gray code translations table. Now I can
check my encoder to ensure it has been calibrated.
Have a good day,
Bill
