CHST-FM is a Canadian radio station, broadcasting at 102.3 FM in London, Ontario. The station uses the on-air brand and format Bob FM. BOB 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.

Approved by the CRTC in 1999,[2] 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 Bob FM in July 2003. Bob FM primarily plays adult hits from the 1980s and 1990s, but will occasionally play songs from before and after this time period (hence the "whatever" in the station's slogan).

In 2007, CHST and the other CHUM stations were sold to CTVglobemedia.

On June 21, 2010, CTVglobemedia announced it had entered into an agreement to sell the station to Rogers Broadcasting Ltd.[3] The sale was approved by the CRTC on December 22, 2010.[4]

On February 9, 2011, Rogers Broadcasting announced that the station would retain the adult hits format, but media analysts speculated that Rogers Media would re-brand the station under its national Jack FM network as "102.3 Jack FM" in the near future, since Rogers owns the Canadian rights. However, this never materialized as Rogers has retained the Bob FM brand. However, the station does have a logo strikingly similar to that of Jack FM's logo. They are one of only 2 Bob FM stations in the U.S. or Canada not to have their signature rectangular logo.

On September 12, 2012, Rogers received approval to change the technical parameters of CHST-FM by increasing the average effective radiated power (ERP) from 5,840 to 20,400 watts (directional antenna with a maximum ERP from 12,100 to 100,000 watts), and by changing its class from B1 to C1.[5]
