One thing I might note, on using a uAvionics beacon for ADS-B Out, is that it requires a transponder for altitude.
That looks pretty slick. I'm confused about how you'd change transponder codes with the AV-20-E though.Not any more! uAvionix now has the tailBeaconX which has a built-in transponder. Used with their AV-20 (or AV30) 2 1/4" (or 3 1/8") panel displays. $2999.00
Thanks for that. That's probably going to work for most folks, but with my fat fingers it may be a problem. It would certainly take me longer to change squawk codes than just hitting five buttons on my GTX 327.
