KSL Newsradio is a pair of radio stations located in Salt Lake City, Utah, which includes the original AM station KSL ( 1160 kHz, licensed to Salt Lake City) and the FM station KSL-FM (102.7 MHz, licensed to Midvale). Both stations simulcast a format of All-News during key hours on weekdays and Talk programming the rest of the time. Owned by Bonneville International (a broadcasting subsidiary of The Church of Jesus Christ of Latter-day Saints), the stations share studios with sister television station KSL-TV in the Broadcast House building at the Triad Center in downtown Salt Lake City.
KSL AM broadcasts at 50,000 watts non-directional, day and night, the maximum power permitted by the Federal Communications Commission. The clear channel Class A station covers most of Northern Utah in the daytime and with a good radio can be heard in much of Western North America at night. The KSL AM transmitter is located west of Salt Lake City International Airport, while the KSL-FM transmitter is located on Farnsworth Peak in the Oquirrh Mountains, southwest of Salt Lake City.
Both KSL's AM and FM transmissions broadcast in HD Radio. KSL-FM carries the Mormon Channel over its HD2 subchannel.
