KJAC (105.5 FM), branded The Colorado Sound, is a noncommercial adult album alternative station operated by Community Radio for Northern Colorado. Its programming serves Fort Collins and the northern Front Range, with additional coverage through translators. The station provides a music service distinct from the organization’s news and public-affairs programming on KUNC.
History
The 105.5 facility began as a commercial station and has carried several formats, including Jack FM and ESPN sports programming. On February 29, 2016, Community Radio for Northern Colorado launched The Colorado Sound on KJAC. The station was later repositioned under the KJAC call sign and Colorado Sound identity. The service combines a curated adult album alternative music format with locally produced programs and regional arts coverage.

FROM THE TIMELINE
Moments in KJAC-FM History
KJAC 105.5 becomes an early U.S. Jack FM
In April 2004, 105.5 FM serving Northern Colorado adopted the KJAC calls and the Jack FM variety-hits format. The station was among the earliest U.S. outlets to use the Jack branding and became a notable bridge between the Fort Collins and Denver radio markets.
KJAC ends Jack FM and joins ESPN simulcast
In September 2012, KJAC 105.5 ended its Jack FM format. After briefly stunting as classic-country Bob FM, the Timnath/Fort Collins signal moved to a simulcast of Denver sports station KDSP/ESPN 102.3.
KJAC launches The Colorado Sound
Community Radio for Northern Colorado launched the noncommercial adult album alternative service The Colorado Sound on KJAC 105.5 FM on February 29, 2016. The change followed the organization’s agreement to acquire KJAC from Front Range Sports Networks, ending the station’s ESPN sports programming and creating a music-focused companion to KUNC.
