What is "kmsb"

KMSB is a Fox-affiliated television station that is licensed to Tucson, Arizona. Owned by Tegna, Inc. and operated by Raycom Media through a shared services agreement with CBS affiliate KOLD-TV, it is a sister to MyNetworkTV affiliate KTTU through a joint sales agreement with Tucker Operating Company. It broadcasts an ATSC digital signal on UHF channel 25 (remapped to virtual channel 11.1 via PSIP) from a transmitter located atop Mount Bigelow; as a result of the transmitter's location, residents in the northern part of Tucson, Oro Valley and Marana cannot receive adequate reception of the station. Its studios are located with KOLD-TV on North Business Park Drive on the northwest side of Tucson, near the Casas Adobes neighborhood.
