I hope you're correct on that. After posting my comment, I looked on the uAvionix page, and the tech specs mentioned not supporting FIS-B. Am I looking at the correct page?

Don, is this what you bought? Is there any difference compared to the discontinued pingEFB that others are mentioning here? My plane partner and I each use a Stratus and Stratux respectively, and this looked like a good way to consolidate down to one ADS-B receiver...
I'm using a Amazon Fire 8 plus to run iFly, and it runs surprisingly well. You do have to sideload it, as Google Play isn't installed, but I've been able to use it with relatively few issues.
