282.60 mhz NORAD Blue 17 channel - Hearing Bigfoot, Surf 11 & 12 with position reports & targeting info. Surf 11 advising they were leaving the area for 15 min, then RTB. Surf 11 then checked in with Joshua Control on 384.70 mhz. I have never heard this freq used before, even during the recent POTUS visits. Maybe it is now used instead of 271.00 Blue 15?

1938z heard Surf 12 calling Surf ops on 271.00 Blue 15, no joy. They finally contacted March command post on 349.40 mhz to have them landline Surf ops. They referred to 271.0 as "Blue 15" and 282.6 as "Blue 17", so the color coded channel designators must still be in use. I haven't heard them used until recently.
