CBO-FM

CBO's Ottawa-area transmitter is located in Camp Fortune, Quebec, while its studios are located in the CBC Ottawa Broadcast Centre on Queen Street (across from the Confederation Line light rail station) in Downtown Ottawa.

[2] The station was the first to broadcast the time signal from the Dominion Observatory in Ottawa, doing so daily at 9 p.m.[3] It operated on 690 AM and later switched to 600.

[1] The call sign of the existing CBO-FM facility (103.3, part of the CBC Stereo network) was then changed to CBOQ-FM.

On November 9, 1989, CHEZ-FM Inc. was denied a license to add a new FM transmitter at Carleton Place on 92.3 MHz to rebroadcast the programming of the CBC's English-language AM network CBO.

[6] On July 5, 2010, the CBC applied to change Brockville's CBOB-FM frequency from 106.5 to 91.9 MHz which received CRTC approval on November 10, 2010.

[14] The CRTC approved the CBC's applications to move both CBOF-1 and CBOM Maniwaki to the FM band on June 1, 2022.
