CHUP-FM is a Canadian radio station broadcasting at 97.7 FM in Calgary, Alberta. The station airs an adult contemporary format branded as Soft Rock 97.7 and is owned by Rawlco Radio. CHUP's studios are located on Railway Street Southeast in Calgary, while its transmitter is located at 85 Street Southwest and Old Banff Coach Road in western Calgary.
As of the Fall 2014 Numeris Radio PPM Data, CHUP was the #15 radio station in Calgary.
The 97.5 FM frequency, adjacent to the new 97.7 FM, was originally occupied by CIRI-FM which moved to 106.5 FM in early 2008 to make room for the new 97.7 FM frequency.
After its approval in 2007, the station began on-air testing on February 19, 2008 as CIGY-FM and officially launched on March 6, 2008 at 10:00am MST. The first song played was Who Says You Can't Go Home by Jon Bon Jovi and Jennifer Nettles. The station's original music format was a hot adult contemporary/country mix. The station was originally branded 97-7 Calgary FM but changed its branding to The New 97-7 FM as of September 2008, then to Mix 97.7 in 2009 while maintaining the same format. In April 2010, the country music lean was dropped and CIGY-FM became a full-time Hot AC station while maintaining the Mix 97.7 branding making it the first time Calgary has had two Hot AC stations as it took on CKCE-FM, which plays more rhythmic-leaning contemporary tracks.
