I was checking today's Mode-S / ADS-B logs and notice some rather strange callsigns from SkyWest Airlines. I have posted a few snippets from the log file below.
A20415 MATTSUXX N229SW E120 Skywest Airlines/... 2011/07/11 17:57:04
A2F71F BUTTSEXX N290SW E120 Skywest Airlines/... 2011/07/11 01:27:28
A2FE8D MATSUUXX N292SW E120 Skywest Airlines/... 2011/07/11 03:29:55
A31120 MATTSUXX N297SW E120 United Express (S... 2011/07/11 16:39:11
Searching previous records on these aircraft indicate this has been happening for some time. The call signs have also been changed on occasion and were mostly "x rated" in nature.
These were received on my Radarbox located in Moreno Valley, CA
