PSA operated four stations in California, all with easy listening formats; KPSA was marketed primarily to women, complete with an in-house poet.

With a weekly audience of nearly two million people, KLVE is among the most listened-to Spanish-language radio stations in the U.S., usually second to WSKQ in New York City, according to Nielsen Audio.

KLVE is unrelated to K-Love, an English-language Christian radio network owned by the non-profit Educational Media Foundation (EMF) based in Rocklin, California.

[11][12] When the EMF acquired Los Angeles's KSWD as part of Entercom's merger with CBS Radio, the broadcaster was required to reach an agreement with Univision in order to use the "K-Love" brand within networked programming on the station; although details were not specified, the station is promoted locally under the name "Positive, Encouraging 100.3", with the positioning statement "the K-Love for Christian music".

[13][14] KLVE's morning show had been co-hosted by the husband-and-wife duo of Omar Velasco and Argelia Atilano (1993 graduate of Garfield High School in East Los Angeles) since 2003.
