Hello. I am A little puzzled. For the past month of flying I had few times when the tower said they weren't receiving my Mode C, it has happened on take off, it has happen inbound for landing. has been intermittent. My set up is Dynon D10A (has a built in encoder), GTX 327, Uvionix EchoUAT, IFD440. in the past I have cycled the transponder and tower was able to see my mode C, another times it didn't happen, another time I cycled the dynon and transponder it worked. today I took off in the morning it was fine, later in the day when I came back tower said i had no mode C, (he sees me, Ident is good, just no ALT) I tried cycling the transponder, Nothing. Tried the D10a, nothing. tried both at the same time Nothing. landed and still no mode C. i will try flying tomorrow to see if it is back alive.
Can anyone guide me how to troubleshoot this one? I was thinking of finding a 327 and swap out with mine to test it for few days. OR?
I am In KMOD for another week or so.
thanks
