Bug: Traffic alerts issued for my own aircraft! (Read 487 times)

I have the HDX with all Dynon components (GPS-2020, transponder, etc.) and ADS-B in and out. At least once every flight, and usually a few times, the map will issue a traffic alert for myself. It shows an aircraft on the map and approximately my location, sometimes offset a tiny bit or indicated +/- 100 feet from my altitude, but it is obviously my echo because there is never any other aircraft there, and the echo goes away in a few seconds typically.

Can you fix this? It's pretty annoying, I don't like getting false traffic alerts because it teaches me to ignore them.

It is a bug in the FAA's TIS software and has been has happening since TIS and the mode S transponders came into use back in the early 2000's.

Does TIS-A send aircraft registration numbers, or is there no way for the Skyview to know that the echo is of myself?

It would be nice if it would ignore TIS echoes that suddenly appear right near oneself since aircraft do not teleport and everybody will just assume it's a bug and ignore it anyway, especially when the directional vector matches the aircraft's own.

FAA TIS does not send N-numbers out. I think when Skyview drops back to TIS ONLY (mode S) thats when the FAA bug sometimes shows up as the echo or reflection of your aircraft.
