Garmin GTX327 and GDL82 glitch
I installed a GDL-82 with fail lamp and anonymous switch in an airplane 6 months ago. Paired to GTX-327 transponder. System checked out fine at the time of install.
Now, the owner reports that anytime he is instructed by ATC to "Ident", the GDL-82 fail light illuminates for about 1 minute. During that time, foreflight ownship verifies the GDL is not transmitting. GDL-82 has the latest firmware...
Anyone with similar setup out there that can report their system performance?
