The station first signed on the air in 2008 with a regional mexican format with the KIMZ call letters. It flipped to a country format as "US 104" with the KUSQ call letters in 2009, which competed against Luverne-based KLQL "K101". After the station's parent company, Absolute Communications, purchased Three Eagles Communications stations in Worthington, the KUSQ format and call letters were moved to the 100,000 watt 95.1 FM signal. On January 5, 2012 KUSQ changed their format to Top 40 (CHR) branded as "104.3 The Party" with the KZTP call letters. Before the flip to CHR, the only other station with the format in the area was Marshall-based 99.7 KKCK. While KKCK uses a full 100,000 watts with a large coverage area, the tower is nearly 60 miles away, which makes it harder to receive than the local stations on portable radios. Sioux Falls-based KKLS-FM "Hot 104.7" can be heard in areas west of Worthington. Most of the station's programming comes from Dial Global's "Hits Now!" network.
