The transmitter tower array is located off Floodway Road near Saint Adolphe. CJOB operates at 50,000 watts, the highest power permitted for Canadian AM stations. But because AM 680 is a clear channel frequency, CJOB must use a directional antenna at all times to avoid interfering with other stations. KNBR San Francisco and KBRW Barrow, Alaska, share Class A status on 680 kHz.
CJOB airs local talk shows during the day, with news-intensive segments during AM and PM drive time. Evenings, CJOB has a sports talk show, and at night, CJOB carries two national shows, "Charles Adler Tonight" and "The Shift with Drex." Weekends feature shows on health, travel, food, technology and cars.
- CJOB first signed on at 8 a.m. Monday, March 11, 1946. CJOB was a 250-watt station at 1340 kHz owned by John Oliver Blick (the "JOB" in the call sign).
- The station moved to 680 kHz and increased its power to 5,000 watts on October 8, 1957. At the same time it installed a new antenna 90 metres (294 ft) high in Fort Whyte, Manitoba, 5 kilometres (3 mi) west of Hwy. 75.
- In 1959 CJOB applied to the Board of Broadcast Governors (BBG), under the name Perimeter Television Broadcasters Ltd., to build Winnipeg's first private television station, but were unsuccessful. The licence was issued to Moffat Broadcasting, which put CJAY-TV on the air in November 1960.
- CJOB was sold to OB Limited in 1964.
- The station moved in 1964 to 930 Portage Avenue.
- In 1978 CJOB's broadcast power increased to 50,000 watts during the daytime, making it the province's second-most powerful station, after 990 CBW, powered at 50,000 watts day and night.

- In 2007 CJOB asked the Canadian Radio-television and Telecommunications Commission (CRTC) for a nested FM frequency at 106.3 transmitter at Starbuck to rebroadcast CJOB (AM) (mono). On September 7, the CRTC denied Corus's application to simulcast the AM radio signal at 106.3 MHz.
- In April 2010, Corus Radio Winnipeg announced the future relocation of its radio broadcast facility to 1440 Rapelje Avenue (since renamed Jack Blick Avenue), as part of a lease agreement between Corus Entertainment and Cadillac Fairview. The relocation to Polo Park was originally slated for January 2011. CJOB 680, CJGV-FM 99.1 (Groove FM) and CJKR-FM 97.5 (Power 97) would become the anchor tenants. Corus Radio Winnipeg planned to occupy the second floor of the three story building, upsizing its radio, production and business operations to 17,500 square feet (1,630 m2). At the time, general manager Garth Buchko said the stations had outgrown their 930 Portage Avenue facility. With the move, Corus Radio Winnipeg would also upgrade to state-of-the-art, fully digital on-air systems.
