Suddenly we're getting these hex codes in lower case, which either the database isn't recognising, or which are new things that aren't in or shouldn't be in the database.
Anyone know what's happening?
EDIT - they are all in the San Francisco area, and Airframes doesn't seem to know any of them, even in capitals. Just watched one landing at SFO, so probably not UAVs.
Could this be a dodgy RadarBox?
