WYNN-FM (106.3 MHz) is a radio station broadcasting a mainstream urban format. The station is licensed by the Federal Communications Commission (FCC) to serve Florence, South Carolina, and broadcast with an effective radiated power (ERP) of 6 kW. WYNN-FM is owned by Cumulus Media.

WSTN-FM played beautiful music in the early 1980s. The station was acquired by WJMX AM 970 and switched to CHR in January 1985 as "106X". In 1988, format rival WPDZ 103.3 was acquired and the station transferred the format and call letters to the newly acquired frequency. In November 1988, the station was sold to WYNN AM 540, which migrated its urban format to FM.

WYNN once aired Doug Banks in the morning and now broadcasts DeDe McGuire.
