I knew adding the FA filter to my Cantenna would improve range, but didn’t know it would be this good!

Just kidding. Must have to do with the bogus “AAAAAA” Mode S code? I definitely don’t have 2100mi of range.
Yeah, that hexid was showing up in multiple places at about the same time and multilateration was tracking either one position or the other semi-randomly (it currently assumes that hexids really are unique and only maintains one track per hexid, so it was mostly luck which location won); you’re seeing results from the “other” solutions.
“N787BK” (hex AAAAAA) appears in the skies over East Anglia in the UK on frequent occasions. Lakenheath F-15E I think. So you might have got an even bigger range
