I have hundreds of hours with transponder and PF without a single false alarm. None of the 50 pilots or so that flying in our region with both PF and transponder are reporting this issue. So it is time for you to conclude this is likely a unique issue with your setup or send your PF to repair.

Ramy,
I have Trig 22 and unfortunately I don't have flawless operation. I hear beeps alerting me to my own transponder (from time to time not consistently with errors in a log file failed to detect own transponder or something like that). Are you suggesting that some of us have faulty units?

I am going to mount soon the PF in my other glider that also has a transponder (different make) and see if I still get false alerts.
