I have a question, that I can't seem to find the answer to anywhere.
I am using the Kinetics SBS-3 and I have picked up over 2200 ModeS numbers, beginning with SA, from SA0001 to SA0FFB. The "SA" series ModeS are not "valid", yet I have received quite a few
In all cases, each of these ModeS's are tracked, sometimes the numbers are used more than 2, or 3, or even more times.
Every time I see it is when there appears to be a slow down in live ModeS and ADS-B traffic. For now, I've labelled it as FAA Practice Tracking and have taken a few videos using the Base Station software and have a few screen captures too.
I'm making an assumption that possibly the FAA guys are taking advantage of the downtime to practice / train, maybe ? The tracks, usually depart/arrive from KTUS, KDMA, KRYN and some of the smaller airports. Other times, it is clearly of tracks that are orbiting. Sometimes, I get the feeling it might be a live transposition of the ModeS data with a radar track and then for a very short time displayed via ADS-B.
I am including a couple of screen shots. Hopefully, someone can advise on this please ?
Thanks for any help or suggestions.
