On your radio, first make sure VOX is turned off.
RigPi uses CAT commands to control radio PTT if the radio supports it. It also provides hardware PTT through the audio connector. Try disconnecting the RJ45 cable from RigPi and restart the radio. Does PTT behave without the cable connected?
If it works, go to the CW Keyer settings page. Click Reset Defaults. Watch the red PTT light as RigPi sends ‘R R’ after the Keyer is reset. Does it light?
Depending on the outcome of these tests, we will go to the next step.
