This question is rather vague, so let me answer this in a couple of ways...
a. If you're looking in our database, a large message with a warning about rebanding shows up
b. If you've lost access to your local system, and you can't hear that raucous racket from the control channel on any of the listed frequencies (and the system hasn't lost power, etc.), subtract 15 Mhz from all the freqs and see if they show up. I would then cross reference them on the FCC database and see if they are there...
