I have Garmin SL40 and Flightcom 403 in my RV-12. When I bought the plane from the original builder the comm radio had a terrible squeal when transmitting. A kind sole on VAF suggested reducing the side tone and that solved the problem.
I have one last issue with the audio system and that is the squelch setting for the intercom. I find that I need two settings ? one for ground when the cabin is quiet and a higher squelch setting during takeoff and cruise flight when the engine is producing power and noise is generated from wind. I don?t know if this is common. The difference in squelch setting is about 90 degrees of knob rotation on the Flightcom 403. I can live with this but it would be so much better if I didn?t have to fiddle with the intercom during change in flight modes. Any help appreciated?
