 |
|
I have an XCom radio in my RV-7A and I am having some problems transmitting. I seem to receive just fine. When I push the PTT button on the pilot control stick I get a static in my headset. If I push the PTT button on the passenger control stick I get the same static (in the pilot headset) with the same intensity. When I switch headsets to my backup headset I don't hear the static when I push the PTT. HOWEVER, the problem is much worse in flight (possibly due to a louder environment); on the ground with the engine shut down the static is minimal. I have not tried the backup headset in flight. I will fly tonight with the other headset to see if this eliminates the problem, but I don't think it will. Since it only happens when transmitting I am starting to think there is a problem with the PTT wiring?? Any ideas to start me out? I will report back with the results of using a different headset. Could this be a gain adjustment needed (I can adjust the gain)?

If you speak into the mic while transmitting, do you hear your voice (from
the sidetone) through the headphones? Are other stations able to hear
your transmission? With good quality? In addition to adjusting the gain,
you might be able to adjust the sidetone volume if everything else appears
to be working properly.
