The FCC has designated channel 14 as a proposed allotment for Tolleson AZ. Were KPPX to wish to vacate channel 51, they would be able to move there, but I believe they would have to do so without compensation, as no incentives have been approved by the FCC for channel 51 licensees who voluntarily move.
Given the fluid nature of incentive and repacking plans, I don't see why KPPX would want to move now instead of holding out in hopes of a financial incentive to relocate.
