KTSB (AM)

KTSB (1170 kHz) is a commercial AM radio station in Tulsa, Oklahoma. It is owned by Griffin Communications and airs a sports radio format. The station is the Tulsa affiliate for Fox Sports Radio, and also carries local shows. KTSB studios and offices are located across from Guthrie Green in Downtown Tulsa, and it transmits from a three-tower facility located along East 11th Street (Route 66) in an undeveloped area of East Tulsa.

KTSB is a clear channel Class A station broadcasting at 50,000 watts, the maximum power for American AM stations. The station uses a non-directional antenna by day, heard over much of Eastern Oklahoma and parts of Kansas, Arkansas and Missouri. It provides secondary coverage as far north as Wichita, as far east as Fayetteville and Fort Smith, Arkansas, and as far west as the fringes of the Oklahoma City area. Under the right conditions, it can be heard across nearly all of Oklahoma's densely populated area, as well as Springfield, the outer suburbs of Kansas City, and slivers of Texas. At night, power is fed to all three towers in a directional pattern to protect the other Class A station on 1170 AM, WWVA in Wheeling, West Virginia. Even with this restriction, KTSB's nighttime signal can be heard over much of the Central United States and well into the Rocky Mountains with a good radio.
