Micheal:
I had similar problems on 20 metres. The radio would go into a feedback
loop with the VOX on and be locked in transmit. I diagnosing the problem I
disconnected the antenna and installed a dummy load. The problem went away.
After some experimenting I discovered the PL-259 that connects to the rig
was installed incorrectly. Replace the PL-259 and no more problem!
Hope this helps.
Good luck
