Has anyone had problems with a uAvionix Tail Beacon on a Skymaster?

I've had no issues with mine other than the fact that when it was first installed, the wrong tail number was programmed into it. It was one letter off. Funny thing is I flew it this way for months and never heard a peep from ATC about it, and my IFR and flight-following flight tracks still showed up on FlightAware.

I only discovered it when I downloaded the app that connects to it via bluetooth. It was an easy fix.

The other issue (if you care) is you can only legally take it up to FL180. You need a 1090-type ADS-B to go above that altitude. Nor can you go international with it. Again, not sure ATC would even care about the altitude restriction, but that's what the regs say.

Final point - A 978 ADS-B like the TailBeacon can be legally switched off during flight, as long as the airspace does not require it. A 1090-type cannot.
