My radio transmits on-off-..-on constantly once I'm a good ways down the runway and while in the air. If I remain on the ground, this behavior doesn't show up.
This failure appeared slowly; when I first noticed it, I could fly for about an hour and the onset would be slowly at first until it became constant. That delay has disappeared entirely. Now it's as soon as I'm airborne.
The behavior does not appear during a run-up to 4000 rpm. I would think that if it was vibration related, that might do it. Nope.
I had thought it was a failed PTT. Replacing one didn't seem to help. I had both sets of audio-jacks tightened too.
I didn't build this RV12, so I have that handicap.
Some suggestions I've had so far is that it might be airflow-related movement interfering with a ground.
Has anyone seen something like this? Any suggestions on where to start? This makes my radio effectively useless.
