'''CHST-FM''' (102.3 [[Hertz|MHz]]) is a Canadian [[radio station]] in [[London, Ontario]]. The station uses the on-air brand and format ''[[Jack FM|Jack]] 102.3''. CHST broadcasts from the [[CFPL-DT|CFPL-TV]] tower in Southwest London. Due to CHST's low [[Effective radiated power|ERP]] relative to some London area radio stations, its broadcast signal covers only [[Middlesex County, Ontario|Middlesex]], [[Elgin County|Elgin]], and [[Oxford County, Ontario|Oxford]] counties. The station's coverage to the west is impeded by co-channel [[WGRT]] in [[Port Huron, Michigan]].

==History==
Approved by the [[Canadian Radio-television and Telecommunications Commission|CRTC]] in 1999,<ref>[http://www.crtc.gc.ca/eng/archive/1999/DB99-482.HTM Decision CRTC 99-482]</ref> 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. The station was bought out by [[Glassbox Television]] in April 2005.

On June 21, 2010, CTVglobemedia and Glassbox announced it had entered into an agreement to sell the station to [[Rogers Media]].{{cn|date=May 2023}} The sale was approved by the [[Canadian Radio-television and Telecommunications Commission|CRTC]] on December 22, 2010.<ref>[http://www.crtc.gc.ca/eng/archive/2010/2010-953.htm Broadcasting Decision CRTC 2010-953]</ref>

On September 12, 2012, Rogers received approval to increase the station's [[effective radiated power]] from 5,840 to 20,400 [[watt]]s ([[directional antenna]] with a maximum ERP from 12,100 to 100,000 watts), and change its class from B1 to C1.<ref>[http://www.crtc.gc.ca/eng/archive/2012/2012-490.htm Broadcasting Decision CRTC 2012-490], CHST-FM London – Technical change, CRTC, September 12, 2012</ref>

Following the acquisition, the station continued to use the "[[Bob FM|Bob]]" name (which was associated with [[Bell Media]] stations) until August 28, 2014, when it adopted the ''[[Jack FM]]'' brand (as with other Rogers-owned [[adult hits]] stations).<ref name=ri-jacklondon>{{cite web|title=Bob Gives Way To Jack in London, ON|url=http://radioinsight.com/blog/headlines/89910/bob-gives-way-to-jack-in-london-on/|website=RadioInsight|date=28 August 2014 |access-date=28 August 2014}}</ref>
