Hi,
I watched rtl1090 all day long and noticed ADF995 TEST1234. I did some searching and found that there are several sites with the USA that have similar to but not quite ADF995 ICAO and several TEST12345. Same ICAO all day long. I thought I saw this yesterday. Beyond my knowledge what's going on with that. See Image. I have it labeled in yellow. Currently Airborne Military Aircraft – ADS-B Exchange
