Educational broadcasting in South Dakota began in 1919 with experimental broadcasts at USD's College of Engineering. USD was granted a full license in 1922, and went on the air that May 29 as WEAJ. It became KUSD in 1925. By 1952, the station settled at 690 AM at 1,000 watts, operating only during daylight hours to protect CBFinMontreal. In 1967, it acquired an FM sister station, KUSD-FM at 89.7. Also in 1967, South Dakota State UniversityinBrookings signed on KESD-FM. The three stations merged in 1982 as South Dakota Public Radio.
On July 5, 1961, KUSD-TV signed on the air as the state's first educational television station. Seven more stations signed on from 1967 to 1975, extending its reach to parts of Minnesota and Iowa.
South Dakota Public Radio merged with South Dakota Public Television, which operated the television network, and ownership of the licenses was transferred from the individual universities to the State Board of Directors for Educational Telecommunications (ET Board), in 1985 to form South Dakota Public Broadcasting. As a part of state government SDPB operates within the Bureau of Information and Telecommunication. Between 1985 and 1991, five other stations joined the radio network. One of them was KCSD, which signed on in 1985 as part of a partnership between Sioux Falls College (now the University of Sioux Falls) and the ET Board in to improve the network's reception in South Dakota's largest city. Until 2013, KCSD's license was held by the University of Sioux Falls and operated by the state network under a management agreement.[1] The network bought KCSD outright in 2013.
In 1992, a Chevrolet Suburban was taken on a joyride through the Vermillion Golf Course, where KUSD (AM)'s towers were located. The Suburban crashed into one of the AM station's towers and knocked it down.[2] While a judge ordered the suspect to pay $48,000,[3] the insurance settlement was not large enough to restore full operations, and KUSD (AM) went off the air for good in 1994.
KUSD-TV's signal had long been spotty in parts of Sioux Falls, even though the channel 2 analog signal traveled a very long distance under normal conditions. Some parts of the area didn't get a clear signal from KUSD-TV until cable gained more penetration in the 1980s. To solve this problem, KCSD-TV signed on in 1995, significantly improving coverage in the state's largest city.[4]
As of February 2017, SDPR now broadcasts the main network over the fifth digital subchannel of the SDPB Television stations, and classical music (which airs on the radio stations' second HD channel) on the television stations' sixth digital subchannel.
During 2009, in the lead-up to the analog-to-digital television transition that would ultimately occur on June 12, SDPB shut down the analog transmitters of its stations on a staggered basis. Listed below are the dates each analog transmitter ceased operations as well as their post-transition channel allocations:[7]
KUSD-TV shut down its analog signal, over VHF channel 2, on February 17, 2009, the original date on which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 34, using virtual channel 2.
KBHE-TV shut down its analog signal, over VHF channel 9, on February 17, 2009. The station's digital signal remained on its pre-transition UHF channel 26, using virtual channel 9.
KCSD-TV shut down its analog signal, over UHF channel 23, on February 17, 2009. The station's digital signal remained on its pre-transition UHF channel 24, using virtual channel 23.
KDSD-TV shut down its analog signal, over UHF channel 16, on February 17, 2009. The station's digital signal remained on its pre-transition UHF channel 17, using virtual channel 16.
KESD-TV shut down its analog signal, over VHF channel 8, on February 17, 2009. The station's digital signal relocated from its pre-transition UHF channel 18 to VHF channel 8 for post-transition operations.
KPSD-TV shut down its analog signal, over VHF channel 13, on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 25 to VHF channel 13 for post-transition operations.
KQSD-TV shut down its analog signal, over VHF channel 11, on February 17, 2009. The station's digital signal relocated from its pre-transition UHF channel 15 to VHF channel 11 for post-transition operations.
KTSD-TV shut down its analog signal, over VHF channel 10, on February 17, 2009. The station's digital signal relocated from its pre-transition UHF channel 21 to VHF channel 10 for post-transition operations.
KZSD-TV shut down its analog signal, over VHF channel 8, on February 17, 2009. The station's digital signal relocated from its pre-transition UHF channel 23 to VHF channel 8 for post-transition operations.
