KULL aired an oldies music format branded as "Kool 92" until April 11, 2005. In 2005, it became Mix 92.5 with a hot adult contemporary format. Over the years, the format meandered between soft and hot adult contemporary but under GAP Broadcasting and Townsquare media the company classified the format at HOT AC. The call sign changed. The oldies format that had been on 92.5 resurfaced on KULL-FM at 100.7.
On January 9, 2023, the station flipped to a Texas and red dirt country format as "92.5 The Ranch", assuming the main signal in a simulcast with sister station KSLI.[2]
