Flightcom 403 problems
My Flightcom 403 just died on me. The intercom portion worked fine but when I pressed the PTT switch, the volume was full up in both headsets. I used the isolate switch and it worked normally. I called up the Flightcom tech and he verified that, when I used the isolate switch and everything worked normally, that it was indeed the intercom. A new Flightcom 403LS was $170 from Aircraft Spruce. Installed it and now everything works well, again.
