Hi all,
Thought I would describe an intermittent issue I've been having, see if any one else has experienced it or has ideas of what I could check next. I have dual GRT HXr EFIS with Trig TY91 comm and TT22 transponder. I will get a messages on the screen, usually "TT22 Not Responding". Sometimes "Trig Transponder Warning", or "Trig XPDR TX Restart". Sometimes it will IDENT all by itself, I'm sure ATC loves me when that happens! I've checked and rechecked wiring, actually rewired it using a new connector. I've changed antenna cable, checked ground connections, tried a different transponder, a different GRT controller. Also tried wiring it to the other EFIS. Sometimes it will act up while still on the ground, other times I might fly 45 minutes or so before it will act up. I've tried ferrite filters on various wires. About the only thing I haven't tried yet is a different antenna. I keep wondering if I'm missing something basic, but I can't think of anything. Any one experience anything similar to this? Thanks.
