CHST-FM is a Canadian radio station, broadcasting at 102.3 FM in London, Ontario. The station uses the on-air brand and format Jack FM. Jack FM broadcasts with an average effective radiated power of 5.84 kW from the CFPL-TV tower in Southwest London. Due to CHST-FM's low ERP relative to some London area radio stations, its broadcast signal covers only Middlesex, Elgin, and Oxford counties. The station's coverage to the west is impeded by co-channel WGRT in Port Huron, Michigan.
Approved by the CRTC in 1999, CHST was launched by CHUM Limited in 2000. It originally used the brand Star 102.3 with a hot adult contemporary format, but was rebranded as the adult hits format Bob FM in July 2003.
On June 21, 2010, CTVglobemedia announced it had entered into an agreement to sell the station to Rogers Communications. The sale was approved by the CRTC on December 22, 2010. Under Rogers ownership, the station retained its variety hits format and the Bob FM branding, despite Rogers holding Canadian rights to the Jack FM brand. However, it did adopt elements of the Jack FM brand, such as a similar logo and the "Playing whatever! Whenever!" slogan.
On September 12, 2012, Rogers received approval to increase the station's effective radiated power from 5,840 to 20,400 watts (directional antenna with a maximum ERP from 12,100 to 100,000 watts), and change its class from B1 to C1.
On August 28, 2014, CHST-FM finally adopted the Jack FM brand, with no change in format.
