This should be available Q1 2017 - it's already popping up on aircraftSpruce & the like, at a sub- $400 price. Quite interesting for those of us with Trig transponders.

In the US, all airspace is "outside of designated ADS-B out airspace" for gliders. Or motorgliders I presume.

What are the consequences of having a Trig 21 vs 22, in both the TABS regulations and pure functionality? I understand that a Trig 21 may not meet TABS regulations, if there ever comes to be some. But will it actually function, if wired to the Trig TN72 source?
