Public license information: Profile

KNBN, virtual and UHF digital channel 21, is the NBC-affiliated television station in Rapid City, South Dakota, United States. It is owned by Jim Simpson's Rapid Broadcasting, and is also the sister station to KWBH-LP. KNBN's transmitter is located in Rapid City.

KNBN can also be seen on translators KKRA-LP on UHF channel 24 and K40GS-D on UHF channel 40; both stations are licensed in Rapid City, though K40GS-D mainly serves Lead and the Black Hills region.


The station signed on the air on May 14, 2000. Despite transmitting its signal on UHF channel 21, KNBN identifies as NewsCenter1 on-air, an artifact of when the main cable systems in the market carried the station on Channel 1, which today is usually used solely to provide a slot for video on demand services, barker channels or electronic program guide services. Currently, KNBN is carried on local cable systems on channel 10, though it retains the NewsCenter1 branding. KEVN was the first primary NBC station in the area, which switched to Fox in 1996 (it has since become an ABC station). After the switch (and before KNBN signed on), NBC was provided via cable from KUSA in Denver.

Digital television[edit]

Digital channels[edit]

The station's digital signal is multiplexed:

21.2 720p KNBN MY Simulcast of KWBH-LP / MyNetworkTV

Analog-to-digital conversion[edit]

KNBN shut down its analog signal, over UHF channel 21, on February 1, 2009, and "flash-cut" its digital signal into operation on channel 21.[4][5] The "flash-cut" was necessary as the station had its original construction permit granted after the FCC finalized the DTV allotment plan on April 27, 1997; as a result, the station did not have a companion channel for a digital signal.

News operation[edit]

KNBN presently broadcasts 13.5 hours of locally produced newscasts each week (with 2.5 hours on weekdays and a half-hour each on Saturdays and Sundays).
