CJOB (680 AM) is a commercial radio station in Winnipeg, Manitoba, Canada. It is owned and operated by Corus Entertainment and airs a news/talk format with news and sports programs. CJOB and its sister stations, CFPG-FM, CJKR-FM, and CKND-DT, have studios and offices at 201 Portage in Winnipeg.
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 680 kHz is a clear channel frequency, CJOB must use a directional antenna at all times to avoid interfering with other stations. Even with this restriction, CJOB's low frequency, transmitter power, and Manitoba's mostly flat land (with near-perfect ground conductivity) allow it to reach almost all of Manitoba during the day.
