Problems with my Garmin GMA 240 audio panel
I was doing some pattern work in my RV-10 today, and I was hearing a noise like someone was keying their mic. I would sometimes hear this at night when someone was trying to light up the runway lights, but this was in broad daylight with only one other plane in the pattern. I finally deduced that I was the only one hearing this, and that's when I noticed all the lights on the GMA 240 panel would flash in unison when I heard this noise.
Obviously there's something screwy with the audio panel. I have no idea what it could be or how to fix it. Any ideas?
