Don’t want to be tracked by the curious.Why do you want non mode-S?
Thanks Jesse. That is what I suspected but had to ask. The 327 is shorter and would require swapping out the tray.There us no drop-in replacement for the 330, but it wouldn’t be hard to convert to a 327.
PIA program (what a name!) is for 1090 equipment, not UATs since most UATs already have anonymous mode.There is the PIA program https://www.faa.gov/air_traffic/technology/equipadsb/privacy Can get a 3rd party callsign from Foreflight.... however I'm not sure if that program is only for 1090ES or would also be appropriate for 1090 + UAT.
