CFHK-FM  CFHK-FM is a radio station licensed to St. Thomas, Ontario, serving the Greater London, Ontario area, that transmits at an effective radiated power of 22,000 watts (60,000 watts peak) on a -high transmitter at 103.1 FM. Owned by Corus Entertainment, the station broadcasts an adult contemporary format branded as "103.1 Fresh Radio". The station's studios and offices are located in London while its transmitter is located on the CFPL-DT tower in Southwest London. CFHK was originally CHLO, an AM station broadcasting on 680 kHz and with studios in St. Thomas, Ontario. In 1963, Rogers Radio Broadcasting Limited wanted to relocate the frequency of its Toronto station, CHFI, from 1540, which is a clear-channel frequency assigned to stations in the United States and the Bahamas, and as thus, CHFI was authorized to broadcast only during the daytime. Rogers selected 680 as the new frequency, which at that time was occupied by CHLO. In the late 1960s, an agreement was reached enabling CHFI to commence 24-hour broadcasting on 680, while sharing the frequency with CHLO; eventually, CHLO would relocate to 1570 in the 1970s. CHLO had a Top 40 music format during the 1960s into the 70s, and was a Music of Your Life station in the mid-1980s. After a number of years as a country station, CHLO moved to the FM band in 1994, changing its calls to CFHK-FM. CFHK, known on-air as "The Hawk", had a modern rock format, which later evolved into classic rock. The station continued to operate out of St. Thomas until the late 1990s. On January 12, 2000, CFHK joined the "Energy Radio" network, while The Hawk moved to co-owned CKDK in Woodstock. The Energy Radio network was unstable and station branding changed frequently. In 2002, the network was pulled. CFHK became local again as "Energy 103", serving only London and surrounding area. In August 2004, Energy Radio changed formats to its current adult top 40 format to go up against adult contemporary station CIQM-FM and adult hits station CHST-FM. The flip to hot AC was caused by previous hot AC station CHST-FM flipping to its current "Bob FM" format in July 2003. In August 2005, the Energy Radio brand was folded completely, and CFHK rebranded as "103-1 Fresh FM", due to the fact it could match the current CFHK calls.
