It should be fine. They aren't moving the tower or transmitter, just the frequency.
As for the Spartanburg county area, with 97.7 Chuck-FM doing so well, Hot doing poorly, and to try to fend off Earth FM, I think they should add 94.1 to Chuck FM. I think it has more potential with the ChuckFM/70s/80s/90s format than the Rhythmic format.
