to electrical noise and interference from computers and similar devices. Corus stated, with respect to the use of the FM spectrum, that it had evaluated the availability of low-power FM frequencies, and found that numerous channels of that type were available for use in Kingston. Conversion to FM and format changes As of 2007, CFFX was carrying an oldies format. In April 2007, CFFX applied to move to FM, and was given approval by the CRTC on August 28, 2007. In September, CFFX began testing at 104.3 FM playing a wide variety of different music formats. On October 15, 2007, CFFX moved from 960 AM to 104.3 FM, adopting an adult contemporary format as Lite 104.3. Because of CRTC regulations, oldies was not yet allowed on FM radio, necessitating a change of formats. At midnight on the evening of January 14, 2008, the AM frequency began a final test of their equipment using their 10,000 watt daytime directional antenna. At the top of each hour, on both AM and FM stations, a special announcement was broadcast, followed by special test material, including morse code and sweep tones. This lasted for several minutes before returning to regular programming. This test was repeated again at 1:00 AM and 2:00 AM. The 960 AM signal was turned off at 6:00 AM EST on January 15, 2008. On August 19, 2010, after the CRTC allowed oldies on FM radio, the station changed its format back to a classic hits format, as well as changing its call sign to CKWS-FM, regaining the CKWS calls it lost back in 1987 as an AM station. On February 24, 2014, the station flipped back to adult contemporary as Hits 104.3. On February 13, 2015, the station rebranded to 104.3 Fresh Radio and changed its format to hot adult contemporary. On April 1, 2016, Shaw Media was sold to Corus Entertainment. References External links 104.3 Fresh Radio Kws Kws Kws Radio stations established in 1942 1942 establishments in Ontario
