History
On July 3, 1970, KSLM-FM signed on the air. It was originally licensed to Salem, about 40 miles (64 km) south of Portland. It was owned by Oregon Radio, Inc. and was the FM counterpart of KSLM (now KZGD).
In 1973, it changed its call sign to KORI. In 1978, KORI changed call letters to KSKD and aired the automated "TM Stereo Rock" Top 40 music service as "Cascade 105". On March 7, 1986, KSKD changed call letters to KXYQ and aired a live and local Top 40 format as "Q105", switching to adult contemporary in 1991. On June 15, 1995, at 5 p.m., after a few hours of stunting, KXYQ changed its format to classic rock, branded as "Earth 105", with the call letters becoming KKRH on July 17, 1995. [6]
Entercom (now Audacy) acquired the station in 1998 for $605,000. [7] On June 5, 1998, at 5 p.m., KKRH began its current hot adult contemporary format as "Rosie 105." It changed its call letters to the current KRSK on August 28, 1998. In January 2000, the spelling changed to "Rosey 105" after a copyright lawsuit by Rosie O'Donnell. [8]
On April 14, 2003, KRSK rebranded as "105.1 The Buzz". [6] [9]
The station downgraded from a class C to a C1 to move the transmitter site into the population center of the Portland radio market in 2004. [7] The city of license was changed from Salem to Molalla, as the transmitter was moved to Portland's West Hills.
In 2011, KRSK began adding more contemporary pop currents, moving the station in an Adult Top 40 direction.
On March 1, 2024, at noon, KRSK relaunched as "Bella 105". [10] The first song on “Bella” was “Wrecking Ball” by Miley Cyrus.
In March 2025, as part of a company-wide series of layoffs at Audacy, station program director Jamie "Tanch" Tanchnyk left his position. On July 14 of that year, multiple radio news outlets began reporting that KRSK would imminently drop the "Bella" branding, and the Hot AC format entirely after 27 years, and begin simulcasting co-owned sports talk radio outlet KFXX as "105.1 The Fan"; one such outlet, RadioInsight, would inadvertently confirm the reports by revealing Audacy had registered the new website 1051thefan.com for the station in its report. The "Bella" format had completely stagnated in the market's Nielsen Audio ratings, with just a 2.6 in the May books. [11] It was eventually confirmed by Audacy, which announced the flip would take place on July 22 at 6:00 a.m.. [12] [13] The final song played on “Bella” was “I’m Not The Only One” by Sam Smith.
On July 24, 2025, Audacy filed to change KFXX's call sign to KRSK, with KRSK (FM) adding the -FM suffix to the existing call sign, effective August 14, 2025. [14]
