ATR Transponder issues!

Cannot get it to work… All my other planes work fine…

can anyone please let me know the correct settings for ON - STBY - ALT OFF etc… I believe I have it set and enable but the signal is never received… If I’m on the ground, it does not work, however once airborne if I enter another code it seems top work?
Thanks…

This might help you.

Hi @CaptainCoop779 ,

We’ve moved your topic to the User Support Hub Aircraft & Systems that is more appropriate to get community support.

Wow… thanks all! I will dig thru this and get back later. Appreciate the input!

I found setting XPDR to Standby then over to ON, seems to make it work… thanks all
