Just found this information at the link below. Looks like they are part of some of the relocation that they are doing in the 800 MHz band. According to the link it looks like they will be moving everything down 15 MHz. If I find out anything else I'll post it.

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.
