So I was flying a couple ILS approaches today and on the second one the GTX 650 would not transmit to ATC. The GMA245 audio panel mic switch light flashed as it was transmitting but no TX indication above the Freq on the GTN, had to switch to com 2 and that was working. I tried rebooting the GTN and the audio panel but still could not get GTN to transmit. It was receiving fine. I decided to fly back to home base and tried it again and the TX annunciated this time and was transmitting again. Radio has been flawless since July. Thought maybe a broken wire or pin issue but it failed and then 10 minutes later was working again and could not duplicate. Not sure if it?s the audio panel not keying the GTN or the GTN just not transmitting. Thinking if it does it again to power off audio panel so to force failsafe and see if the GTN transmits. Anyone have any ideas? Steve do you have any ideas?
Thanks,
Steve
