February 8, at 6 a.m., the simulcasting switched to AC-formatted KIOI San Francisco. On February 9, from 6 a.m. to 6 p.m., the simulcast switched to modern rock-leaning top 40 WXKS-FM Boston. At 6 p.m., the simulcasting of sister stations ended. WKTU (1996–present) At 6 p.m. on February 9, 1996, WYNY switched its stunting to a heartbeat sound effect, promoting the launch of a new format coming the following day at Noon. At that time, WKTU was relaunched on 103.5 FM with a dance-based CHR format; WKTU's first song was "Gonna Make You Sweat" by C+C Music Factory. The station went to number one in the Arbitron ratings. Drag performer RuPaul co-hosted mornings with Michelle Visage, Lisa Taylor and Freddie Colon around this period, further helping their ratings. Sean "Hollywood" Hamilton and Goumba Johnny made their debut at night, and after much success, were moved to mornings in January 1998. By 2002, the moderate amount of rap played on the station was gone and the station evolved into more of a Rhythmic Hot AC. On May 31, 2006, WKTU announced that actress/comedian Whoopi Goldberg would become the station's new morning host, and that the station would serve as the flagship station for her syndicated morning show. Her show, which aired mostly on AC and Rhythmic outlets in the United States, especially those owned by WKTU's now-parent company Clear Channel Communications, began on July 31, 2006.

WKTU management insisted that there were no plans to flip formats, even with Goldberg in mornings. Another surprise move was the reunion of former KTU morning hosts Sean "Hollywood" Hamilton and Goumba Johnny, who hosted afternoons on the station beginning September 5, 2006. Hamilton continues to host the syndicated shows the Weekend Top 30 and the Remix Top 30 heard in cites across America and around the world. However, on September 9, 2006, after many format flips by Clear Channel of other radio stations throughout the country, WKTU took on the upbeat Rhythmic AC direction by playing only popular current rhythmic material, as well as increasing the airplay of older
