Hi Kenny,
The Thai codes are unknown to me, possible military.
The others are all miscoding their former identity
A50B8B decodes to N424LX this is now HS-BRM,Beechjet 400A c/n RK-245
A580CD decodes to N45383 now HS-MVK, Bell 412EP, c/n 36333, HRH Crown Prince Maha Vajiralongkorn
A848A5 decodes to N6328L now HS-SYS Cessna T182T Skylane c/n T18208895
ADC9BE decodes to N988KA now HS-ATS, Beech B200 Super King Air, c/n BB-1988,
Aeronautical Radio of Thailand
Thanks again
