We installed a new Micro Air in a sailplane. This is the 5th one we
have installed. All have worked great except this last one receives
perfectly, but when transmitting it sounds garbled. The boom mic is a
Micro Air. Anyone have an idea what this could be?

Thanks

One other possibility is a bad microphone. I bought an XCOM and the
boom mic which is the same microphone as Microair where the core of
the microphone was bad. No amount of adjusting the gain or any other
normal adjustments woud fix it. The XCOM engineers and Paul Remde at
Cumulus Soaring sorted it out and replaced it with a new one and the
problem was solved. They also grounded the shield of the microphone
cable right at the mount and at the radio end which helped with the
"noise" level in the line.
