My GTX-327 transponder does not seem to show the "R" reply symbol often (something like once every few minutes). I though I had a problem with my antenna/wiring, and double checked everything. Borrowed a friend's transponder, same thing.
Tonight I went out and asked ATC to give me a transponder check. He gave me my own VFR code, and flew for about a 1/2 hour. In that time, I caught a glimpse of the "R" reply symbol maybe only twice. ATC subsequently told me they tracked me all along.
My question is this: Is the "R" indication not equivalent to the interrogation/reply light on the tube transponders? Should I not be seeing this every few seconds, as the radar antenna sweeps me?
Given that a second unit behaves the same way in my setup, as well as in my friend's plane, do other people see this same behaviour as described above? Inquiring mind wants to know.
