On June 26, 2006, the station changed its call letters to WKTC (standing for "Television of Columbia," according to the station's co-owner). On June 28, the station began running advertisements in the "Columbia Free Times" newspaper featuring the cast of one of MyNetworkTV's original telenovelas "Desire", with the text "September 5 / It's a whole new ballgame," alongside a stylized "My 63" logo and the new call letters. In August 2007, WBHQ Columbia, LLC converted W67DP into the market's Telemundo affiliate, using the calls "WNXG". Later that month, WKTC began operating its full-power digital signal on channel 39. WBHQ Columbia, LLC also signed on a low-power MyNetworkTV-affiliated station in Wilmington, North Carolina, W47CK (branded as "WMYW"), and a low-power Telemundo-affiliated station in Savannah, Georgia, WHDS-LD.
