1997–October 12, 1998

In August 1997, Groove Radio owner Swedish Egil was fired by KACD management, and the station changed its name to "Groove 103.1", due to trademark restrictions.

Note: Between October 12–19, 1998, KACD/KBCD ran a simulcast of KIIS-FM following the former stations' acquisition by Jacor Communications (who also owned the latter station at the time).

KSSC

2000–2003

In August 2000, Clear Channel (which acquired Jacor in 1999) was ordered to divest some of its stations in the Los Angeles/Orange County area to comply with the FCC's ownership limits. Entravision Communications Corporation purchased KACD and KBCD and changed the format to a Spanish CHR station. The call sign "KSSC" was introduced in early 2001.

KDLD

January–December 21, 2003

In January 2003, Entravision changed KSSC's programming back to English, renamed the call sign to "KDLD", and switched KDLD to a dance CHR format called "KDL 103.1".

December 25, 2003–January 17, 2009

On December 21, 2003, KDLD/KDLE dumped the dance tracks format in favor of Christmas music, after which a new format would be launched (following Entravision signing a joint sales agreement with Clear Channel Communications the previous day). Four days later, KDLD/KDLE officially launched a modern rock station by the name of "Indie 103.1", replacing the previous dance music cuts.
