KSNE first signed on the air in 1987 as KRLV 106.5 FM. The call letters were changed from KRLV to KSNE in the mid 2005s. KSNE/KRLV ran its own locally produced weeknight show known as Love Songs For Las Vegas hosted by local jock Robert Holiday in the same time slot. "Love Songs For Las Vegas" ran from 1991–1998, and was replaced by the syndicated Delilah show until 2010. the delilah show came back in late 2011. KRLV 106.5 was known as Continuous Soft Rock in 1987 until 1995. KRLV played Hot AC until the changeover to call letters KSNE. The KRLV callsign moved to 1340 AM.
The new KSNE 106.5 FM became known as "Continuous Soft Favorites" or "Continuous Soft Hits". KSNE began to play more soft AC focusing on such artists as Kenny G, Michael Bolton, Amy Grant, etc. This format continued until the mid-2000s when KSNE began to add more soft rock and current hits. In recent years, KSNE has become a more upbeat mainstream AC station, and today almost all of the songs heard on KSNE are from 1980 until the present. Sunny 106.5 plays Christmas music during the holiday season, as so happens to most iHeart-owned AC stations.
