That's not correct. A full power station can file for non-commercial status in the commercial band. The former WPFB-FM, Middletown, OH and WPAY-FM, Portsmouth, Ohio are both former commercial stations now owned by Northern Kentucky University but maintaining the same facilities they always had.
Would there have even been the possibility of the license going to a "community group", given that non-profit full power stations are restricted to the area between 87.9 and 91.9 on the dial? A low-power non-profit could go on 107.9 for the time being but would probably have to give that up once the full-power license was taken over by another company.
