I am hoping for some guidance regarding a capricious KT-76A transponder. It works normally for a while, and then the Mode C cuts out. I am using a Dynon D-100 for the altitude encoder, then Dynon's grey-code converter to send the signal to the transponder. All the physical connections are sound, and the Dynon components are pretty robust. Any suggestions on where I should start trouble-shooting before I call the avionics shop guys out to the plane?
Thanks

In my limited experience, the tray connector gives a lot of trouble. If it is an older unit especially, try removing and inserting it or just applying pressure to the face and see if it starts working. If so I’d suggest getting a new connector.

I'll 2nd Tim's view. I had a KT-76A that did the same thing and I found one of the fingers in the tray connector was slightly bent and was the cause. I replaced that particular spring finger in the tray connector and had no further problem with the transponder. Cost...less than a buck for a new spring finger from my avionics shop. This was one of those "pull your hair out" problems as it was really difficult to see the bend when you looked at the back of the tray with a flashlight but when I looked closely I could see that one spring finger didn't look quite right. Good luck.

It appears that you are subscribed to every forum
on the Matronics servers. I imagine that your
email load is pretty large. You goto this link
http://www.matronics.com/subscribe/
and enter your email address in the box,
hit 'uncheck all' and 'subscription' and
then 'execute'.
