KOOL FM Countdown Commercial 2003

Launched in 1947 as CFRA-FM, simulcasting the programming of its AM sister station. In 1959, the station began airing some separate programming.  Two years later, in 1961, the station's programming became fully independent of CFRA's, and the station adopted the callsign CFMO. CFRA and CFMO were subsequently acquired by CHUM Limited in 1968.

The station's MOR/Beautiful Music format included an unwavering diet of traditional artists such as Bing Crosby, Mantovani, Peggy Lee, Ronnie Aldrich, the Somerset Strings, Frank Sinatra, Barbra Streisand, The Carpenters and others of the same genre.

As the 1990s began, CFMO begins moving toward soft adult contemporary, playing more contemporary music and fewer instrumentals. CHUM dropped the longtime easy listening format on August 28, 1992, adopting the CKKL-FM calls and the brand name Kool FM for its new Hot AC format. The first song was Time, Love & Tenderness by Michael Bolton. The CFMO calls and format were picked up by CHEZ-FM Inc., and adopted on what is now CKBY. During their Hot AC days, they aired mostly contemporary hits during the evening hours (in large part due to CRTC regulations banning FM stations for having more than 50% of hit material on their playlists to protect AM stations and French-language stations), as well as the dance music show "Pirate Radio" with Chris Sheppard on Saturday nights. During the 1990s, CKKL competed against Top 40 stations CKTF-FM (which airs in French) and AM station Energy 1200 (which aired in English). Station liners during this time promoted "Hit Music on FM", directly targeting Energy 1200 listeners. After "Energy" flipped to alternative rock in 1997, CKKL was considered the default English-language hit music station in Ottawa. By February 2003, when CIHT-FM (now a CHR station) launched with its rhythmic contemporary format, CKKL completely shifted to CHR.

On May 31, 2003, at 9:39 AM, CKKL-FM dropped its CHR/Top 40 format, and began stunting with the audio from the movie What About Bob?. After the movie aired, snippets of music played, with "Bob FM" launching at Noon that day, adopting the adult hits format. The first song on "Bob" was I Want A New Drug by Huey Lewis and The News.

In 2007, CTVglobemedia bought CKKL-FM along with the other CHUM Limited properties. In 2011, Bell Canada acquired CTVglobemedia, renaming the company as Bell Media.

On November 10, 2014, Bell Media announced that the "Bob FM" format would be discontinued, citing changing "market conditions" and the need to "pursue a new opportunity". All of the station's on-air talent, including Cub Carson, were laid off, and the station began airing blocks of music punctuated by promos announcing an impending relaunch. Its website referred Bob FM listeners to the online stream of sister station CJPT-FM. On November 12, 2014 CKKL flipped to country as New Country 94, launching with a marathon of 10,000 songs played commercial-free.

On May 28, 2019, the station was renamed Pure Country 94 as part of a nationwide rebranding.
