Mine had the same problem when first installed. There was too great a
voltage drop using the old wiring through the glider's master power
switch. Once I bypassed this switch, the unit worked very well. Of
course, I didn't discover this until I had rewired the unit a second
time, thinking I must have made some mistake on the first attempt.

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
