Baofeng UV-3R: Work-around to UV-3R Will Not Stop Transmitting

Julian, G4ILO, is at it again with some good information for a problem that has cropped up on a couple of rigs.

After sending and releasing the PTT button, the radio continues to transmit. It happens on VHF, using the supplied microphone/ear piece, and the Menu Item 7 Power set to "High".

RF is leaking into the PTT circuit via the wire.

1. Switch Menu Item 7 Power to "Low" or
2. Wind a couple of turns of the microphone cable on to a split ferrite.

  1. Even winding the microphone wire up a few turns, on the connector side, will help.
