CBOF-FM

CBOF-FM (90.7 MHz) is a non-commercial Canadian radio station located in Ottawa, Ontario. It airs a French language news-talk radio format, much of which comes from the Ici Radio-Canada Première network. The studios and offices are located at the CBC Ottawa Broadcast Centre on Queen Street (across from the Confederation Line light rail station) in Downtown Ottawa.
Owned and operated by the Canadian Broadcasting Corporation (French: Société Radio-Canada), CBOF-FM has an effective radiated power (ERP) of 84,000 watts as a class C1 station, using an omnidirectional antenna located off Chemin Dunlop in Camp Fortune, Quebec.

History.
The station signed on in 1964 as CBOF. It was originally on the AM band at 1250 kHz, with 10,000 watts day and night. Before then, Radio-Canada relied on privately owned AM 970 CKCH in nearby Hull, Quebec, as well as the 50,000-watt signal of Montreal's AM 690 CBF, to serve Ottawa's francophones.
On January 15, 1975 the Canadian Radio-television and Telecommunications Commission (CRTC) approved the CBC's application to increase CBOF's signal from 10,000 watts to 50,000 watts day and night at 1250 kHz. In the 1980s, the CBC made the decision to begin moving many of its English and French-language AM stations to the FM dial.
The CRTC approved the CBC's application to convert CBOF from the AM band to the FM band, on November 9, 1989. CBOF moved to its current frequency on 90.7 MHz on January 7, 1991 as CBOF-FM. After a period of simulcasting on both AM and FM, the AM transmitter was shutdown. Its sister station on 102.5, on the Radio-Canada Musique network, which used the CBOF-FM call sign before that date, is now known as CBOX-FM.
CBOF-FM, like all Première network stations but unlike most FM stations, broadcasts in mono. While still on the AM dial, CBOF experimented with AM stereo broadcasts between 1984 and 1987, testing all four AM stereo systems (C-QUAM, Kahn-Hazeltine, Harris and Magnavox) proposed at the time.
