Hey Everyone,
This one is stumping me. A couple flight hours ago the GNS530w in my RV8 started developing static on the com radio. Only when receiving a transmission (ie it's not constant, only when someone else is transmitting, I'm receiving ATIS, etc..). Apparently I'm having trouble transmitting also as when I tried to call the local TRACON 20 miles away they couldn't get me. I troubleshot the antenna, cables, audio panel, headset, etc.. and pretty much narrowed it down to the 530 itself. Garmin wants $2300 for a flat rate repair. Darn!
So I flew again tonight to double check something and now my TruTrak EFIS started acting up. Static on the screen, eventually so bad the screen was unreadable. Hmmm....
I'm starting to wonder if something in the plane is generating interference. One by one I pulled each breaker in the plane, but the problem persisted. I can duplicate the radio problem on the ground as well with the engine off. Voltage and amperage are good.
Am I missing something? I'm inclined to think the problems are coincidental, but I figured I'd throw it out there and see.
