They moved to 101.7 when WMGL moved from 101.7 to 107.3 after the station on 107.5 moved to the Columbia market. To do that they needed WKZQ in Myrtle Beach to change frequencies so WKZQ downgraded its signal and took the 96.1 frequency. WWBD 95.9 moved into Charleston.
As for the Wave format I heard it was online somewhere, but the actual station that was The Wave decided to be Chuck and play "everything".
