The station launched in 1983 as a country station branded as "C-107" with the KCID-FM call sign. In 1997, the station flipped to a Modern AC format and was rebranded as "107.1 CID". On May 4, 1999, the station flipped to Adult Contemporary and was rebranded as "Star 107.1". In 2002, KCID-FM changed its call sign to KTHI and flipped to a classic hits format and rebranded as "107.1 K-Hits".
On May 2, 2024, as part of a series of layoffs at Lotus' Boise stations, midday host Barry Lewis and afternoon host Bridget Bonde left the station. On May 6 at 9 a.m. after playing "It's the End of the World as We Know It (And I Feel Fine)" by R.E.M., KTHI dropped the classic hits format after 22 years and began stunting, looping a playlist of songs themed around change in some fashion and declaring it was "time for a change" for the station. At 10 a.m., KTHI flipped to classic country as "107.1 Hank FM", joining a series of stations nationwide launching the format that year; the first song on "Hank" was "It's Five O'Clock Somewhere" by Alan Jackson and Jimmy Buffett. It joins a crowded country field in the market with three other stations - KIZN, KQBL, and KAWO.[2]
Ownership Changes
Journal Communications (KTHI's former owner) and the E. W. Scripps Company announced on July 30, 2014, that the two companies would merge to create a new broadcast company under the E.W. Scripps Company name that will own the two companies' broadcast properties, including KTHI. The transaction is slated to be completed in 2015, pending shareholder and regulatory approvals.[3]
In January 2018, Scripps announced that it would sell all of its radio stations.[4] In August 2018, Lotus Communications announced that it would acquire Scripps' Boise & Tucson clusters for $8 million.[5] The sale was completed on December 12.[6]
