Trig TT-21 is a game changer. You get Mode S/1090ES ADS-B out
capabilities for future possible use and more immediately, it is more
compact, easier to install and uses less power than other options.

Could you confirm that Trig will not work in A/C-only radar environment?

It is a Mode S transponder. It is compatible with Mode A/C SSR. Think
of Mode S as an enhancement to Mode A/C. It's not an alternate choice.
It really makes no sense to ask if these Mode S transponders support
mode A/C.

Paul's comparision table says it's just "Mode S", while Becker 6401 is
"Mode A, A+C, S". Technically it is possible to create a mode-S only
transponder. But I'm not sure if it's legal (certifiable).
If Trig supports A/C, that's good to know!

During my certification testing, the tech initially used a Mode A/C tester
as his Mode S test set was out being calibrated. The TRIG passed all Mode
A/C tests.
