[2] The upgrade was made in June 2013, and on August 27, 2013, K265CA had broken off from rebroadcasting KTEG and began airing its own format from KTEG-HD2 playing Christmas music, which began promoting itself as "Santa 100.9" on September 4, being the first station in broadcast radio to flip to Christmas music for the holidays, and setting a record for the earliest any station in the United States has ever flipped to Christmas music before the holiday itself and possibly the longest any terrestrial radio station has ever run that format.

[3] The Christmas music format had aired commercial free for four months, which also put it in direct competition with KMGA, an Adult Contemporary station which usually changes to the all Christmas music format at about mid-November.

On January 2, 2014, at Midnight, K265CA launched a Rhythmic Oldies format branded as "Hot 100.9" that features hip-hop, R&B and dance-pop from the 1980s, 1990s and early 2000s.

[6] On December 14, 2018, the urban format and the "Beat" branding were dropped and the station began stunting with Christmas music again as "Santa 100.9".

"[7][8] On January 22, 2021, at midnight, after playing "Endless Love" by Diana Ross and Lionel Richie, K265CA began stunting with a repeated 3-hour loop of various television theme songs.
