"Trig" TT22 (I hate autocorrect!)
That indicates to me that it is not currently approved.Plan to meet FAA 2020 ADS-B OUT requirement once TSO-C154c certification has been completed
L3 NGT-1000 doesn't look like it will work with your KT-76A, so if you're in set on keeping that transponder I'd be looking at the RANGR Lite FDL-978-TXL if I had to buy something now. Just my opinion though, based on reading the manufacturer's web sites and FAA Equip ADS-B page. I have zero hands on experience with any of them.A bit more info.....
Currently have/use a KT 76A (with 2 spares), so don't want to change transponders.
Only WAAS source is the GDL 39 in
I display WX/traffic on the 696 (panel mounted) OR on an I pad on a kneeboard .....use with Garmin Pilot app.
Would like to stay with my current equip. and only purchase a small WAAS unit with antenna for 2020 compliance which I'll mount remote in baggage area.
I'm going to Sun N Fun for 2 days only....don't want to spend/waste a bunch of time sourcing the cheapest APPROVED product. Ideally would like names of product to look at/purchase while I'm there, as they usually have show specials/discounts during these fly ins.
Thx in advance for all help......Marvin
The KT-76A's are loosing their value very quickly. If you get a new transponder to support ADS-B out you won't likely need 2 spares. On the other hand, you can get KT-76A spares cheap.
Food for thought. There are transponders that will mount in the same space as the KT-76A, then there is no new box to mount, just the new antenna. That saves on cost.
