Ok I guess I misunderstood the objective and the rules. I'll try to explain:
Compliance with the 2020 requirement, which is for ADS-B out only, can be achieved:
via a Mode S transponder coupled to a Waas GPS,
or
by a Mode C transponder/ UAT combination (limiting your Taylorcraft to 18000ft lol)
Not exactly sure why there would be such strict data integrity requirements on transponders and not UAT, but perhaps that's yet to come.
Don't need either if you're not interested in Class C airspace (or if you're Marty hehe)
Anyway my KT76A was working perfectly but was over 20 years old, so I suppose replacing it is not too much of a heartache.
The Uavionix is $1850 which seems reasonable for those without a WAAS data source. Perhaps prices will get better as there seems to be some competition in this space.
But I already have a WAAS GPS so for another $177 the TT31 gets me compliance, and installation was easy. I also don't need to remember to turn my transponder on and off any more... one less thing.
I have a TT21 in my Taylorcraft powered by a lithium battery, but no nav lights. What I'll need is a WAAS data source if and when I decide to install ADS-B out.
These Trig transponders have very low power requirements which is why I chose the TT21, along with knowledgeable support from Trig.
I have no skin in this game, just sharing information.
By the way if anyone is looking for an excellent KT76A, no rack, perfect bezel send me a pm.
