History

KLYY signed on in 1959 under the call letters of KDUO, airing religious programming. The KDUO call letters were used as it is the acronym for the phrase, "D o U nto O thers...".

KDUO would later adopt an easy listening music format. However, the format was in decline in the 1980s and KDUO's ratings were in a steady decline. In the spring of 1992, KDUO dropped the easy listening music format in favor of oldies branded as "K-Hits 97.5". The KDUO call letters were changed to KHTX to match its new branding.

However, the ratings did not improve much which might be attributed to their marketing strategy. Instead of a direct challenge to KOLA, which was airing a similar format via satellite, it elected to target KRTH which was not successful likely because it did not cover the entire Greater Los Angeles area and competition was fierce as KCBS-FM aired an oldies music format at this time.
