For you Garmin experts out there.
Helping an RV-14 builder with a flying plane. He has a Garmin radio stack (GTN-650, GTR 200 and GMA 240 Audio Panel).
The panel was wired and tested by an avionics shop. The two comm antennas are mounted in per plans locations. The antennas and feed lines have been checked with an antenna analyzer.
Both radios work fine by themselves. When transmitting on the GTR 200 and monitoring another frequency on the GTN-650 all is fine. When transmitting on the GTN-650 and monitoring another frequency on the GTR 200, the GTR 200 squelch is broken and feeds noise into the audio panel.
After all the checks I'm convinced the problem is with the GTR 200.
Is this a known issue with the GTR 200? I assume I can just crank the squelch setting up a lot higher but hoping there is another fix.
