I have upgraded the avionic of my RV-7.
For the communications, I have installed a GTN 650 and a SL40 connected to a GMA 240.
I got some bugs, 3 with the COM.
First, when I transmit on COM #1 (GTN 650), I don?t understand my voice in my headset. ATC understand me clearly and I understand clearly it answer. Nothing wrong with the COMM 2. I double check the wiring between GTN and the GMA, all seems OK.
Second, I have a message in the GTN saying: Audio panel is inoperative or connection to GTN is lost.
Third, when I synthonyse a VOR frequency, I hear the morse signal that sound like a tok totok tok instead of a usual VOR morse code sound.
Any idea?
