CJRQ-FM is a Canadian radio station, which broadcasts in Sudbury, Ontario. The station uses the on-air brand Q92, and airs at 92.7 MHz on the FM band. The station airs a mainstream/active rock format.
The station first aired as CJRQ in 1990. From 1935 to 1990, it was an AM station, airing under the call letters CKSO.
When the station began broadcasting in 1935, CKSO's original frequency was at 780 kHz, until it moved to 790 kHz in 1941. For much of its history, the station was an affiliate of the CBC's Trans-Canada Network.
In 1976, 790 CKSO received approval to increase their power from 10,000 watts day and 5,000 watts night to 50,000 watts, full-time. Since the power increase, the station's AM signal has been heard as far away as Europe and some areas of the United States during the nighttime hours.
CKSO and sister station CIGM were owned by Cambrian Broadcasting, who sold them to United Broadcasting in 1979. Cambrian was in a financial crisis due to the near-bankruptcy of its television station in the city, CICI, but the sale failed to resolve the crisis.
As CKSO, the station aired a contemporary hit radio format, distinguishing itself from competitor CHNO by targeting a more adult audience with adult contemporary and rock hits as opposed to CHNO's more youth-oriented Top 40 format. During this era, the station used brandings such as "Radio 79 CKSO", "Music Radio CKSO" and "Favourite Hits AM 790".
Conversion to CJRQ
On March 16, 1990, the CRTC approved Telemedia Communications Ontario Inc.'s application to amend the Promise of Performance for CIGM-FM Sudbury by changing the music format from Group III (Country and Country-Oriented) to Group IV (40% Pop and Rock-Softer; 60% Pop and Rock-Harder).  Two months later on May 18, 1990, CKSO and CIGM swapped frequencies. CIGM moved to CKSO's 790 slot on the AM band, and CKSO took on the new call letters CJRQ and CIGM's 92.7 MHz FM frequency.
While CKSO had been a perennial second in the radio ratings against CHNO, CJRQ quickly became the most-listened to radio station in Northern Ontario, and retained that status until the late 1990s, when CJMX's adult contemporary format overtook Q92 in the ratings. The station took its biggest ratings hit after CHNO converted to the FM band in 2000, dropping to 22.9 per cent of the radio audience in 2000 from 30.9 per cent in 1999.
In 1997, the station was censured by the Canadian Broadcast Standards Council over a 1995 broadcast. The station aired a daily programming feature in which it asked a daily poll question on an issue in the news, and subsequently broadcast a selection of listener comments; the CBSC complaint pertained to a question about whether the Ontario Health Insurance Plan should cover sex-reassignment surgery for transgender residents of the province, and one listener comment that was broadcast was singled out as especially homophobic and transphobic.
In 1999, Telemedia acquired CJMX from the Pelmorex Radio Network as well. In 2002, Telemedia was purchased by Standard Broadcasting. Shortly afterward, Standard sold CJRQ, CIGM and CJMX to Rogers Communications.
In 2009, CJRQ's longtime sister station AM 790 CIGM was sold to Newcap Broadcasting and moved to the FM dial in August that same year.
