>> I don't think rebanding will happen till the race is over.
Maybe we're putting the cart before the horse ?
I see nothing in the FCC ULS database to indicate that Concord / Cabarrus County has a pending or finalized license showing the additional frequencies ( I would think both the old and the rebanded frequencies would appear on the license during the transition period).
Also, as a footnote, the "down 15" rule is not set in stone, since there may already be another local licensee - public safety or commercial - on the frequency in the 851-854 band.
