Thank you Ron. Unfortunately they're in Canada now (see my updates above) But I'll put your freqs into the scanner and try to catch them on their return trip.
Yesterday (June 23rd), I caught the MD A-10s on their return flight from the Bagotville airshow through Maine to their stopover at Hanscom AFB (KBED) in Massachusetts. They used 266.6 again for A-A chatter. Was able to listen to them for about 20 minutes. Thanks again everyone for the freqs. Very much appreciated!
