The KWID studios are located in the unincorporated community of Spring Valley in Clark County and its transmitter is on Black Mountain in Henderson.

KFMS simulcast KIIS-FM in Los Angeles, including Rick Dees' weekday morning program, while Buck Head from WFLZ-FM in Tampa hosted weeknights.

Over time, KFMS began adding more local disc jockeys, including Kate and Rick Kelly from KQOL-FM (93.1 FM).

After KYHT flipped to hot adult contemporary in 2001, KFMS discontinued its simulcast of KIIS-FM, adjusted its format to include more hip hop music, and added a local morning show hosted by Trejo and Nikki.

In January 2003, the station debuted a rhythmic contemporary format with the branding "Wild 102" and the slogan "Where Hip Hop Lives"; the call letters changed to KWID.
