KDLT-TV, virtual channel 46 (UHF digital channel 21), is an NBC-affiliated television station licensed to Sioux Falls, South Dakota, United States, serving eastern South Dakota and southwestern Minnesota. The station is owned by Red River Broadcasting. KDLT's studios are located on South Westport Avenue in Sioux Falls, and its transmitter is located southeast of the city near Rowena.

KDLT operates a full-powered satellite station: KDLV-TV (virtual channel 5, UHF digital channel 26) in Mitchell, with transmitter near Plankinton.


On June 12, 1960, KDLT started broadcasting from Mitchell, South Dakota as KORN-TV on channel 5, an NBC affiliate with a secondary ABC affiliation. The station's original call letters were intended to honor the famous Mitchell Corn Palace. It was owned by Mitchell Broadcasting Associates. Only a month later, KSOO-TV (now KSFY-TV) signed on. From then until 1969, KSOO-TV and KORN-TV operated as a regional network, although separately owned. KSOO-TV served the eastern portion of the market, while KORN-TV served the western portion. But in April 1969, the Federal Communications Commission ruled against this combination, suggesting that they operate as competitors in the Sioux Falls–Mitchell market. So on May 12 of that year, Channel 5 affiliated with ABC and moved its tower closer to Sioux Falls, although KCAU-TV in Sioux City was well received in Sioux Falls and identified at that time as Siouxland ABC.

Mitchell Broadcasting sold the station to Buford Television of Tyler, Texas in 1972. The new owners changed the calls to KXON-TV. Buford sold the station to Gillett Broadcasting in 1978. In 1982, KXON changed its call letters to KDLT when it was purchased by Dakotaland Broadcasting. The next year, KDLT and KSFY switched affiliations, with KSFY getting ABC and KDLT returning to NBC. At the time of the switch, ABC was the highest-rated network in the nation with NBC in third. KSFY had three full-power transmitters to KDLT's one, making it logical for the more popular network to align with a station with better coverage. The next year, NBC and ABC's ratings flip-flopped, leaving KDLT once again affiliated with the more popular network. Dakotaland Broadcasting eventually sold KDLT to Heritage Broadcasting in 1985. Heritage Broadcasting became Heritage Media in 1987 when it merged with Rollins Telecasting. The station eventually moved its main studio to Sioux Falls in the mid to late 1980s.

Heritage Media sold KDLT to current owner Red River Broadcasting in 1994. On September 8, 1998, KDLT moved its city of license to Sioux Falls and began broadcasting on channel 46 from a new tower in Rowena, where most of the other Sioux Falls stations have their towers. This was largely because the channel 5 tower was too far away from Sioux Falls to adequately cover it with a digital signal. FCC rules required a station's digital signal to cover at least 80 percent of its analog footprint. Channel 5 in Mitchell survives as a full-power satellite, KDLV.

Due to the way the changeover was structured legally, KDLV operates under KDLT's old license on channel 5.[1] KDLT's current facility, on channel 46 in Sioux Falls, is officially a new license; its construction permit was issued on April 1, 1997 under the call letters KDLV; the two stations swapped callsigns on September 8, 1998.[2]

On May 1, 2018, Gray Television announced its purchase of KDLT-TV for $32.5 million. The deal would create a duopoly with KSFY-TV.[3] The combined operation will presumably be based at KSFY's studios on Courthouse Square in Sioux Falls; in its announcement of the KDLT purchase, Gray noted that the KSFY studio has enough space to house a second station's news and sales department.[4] Gray will need to obtain a waiver in order to complete the deal, since the FCC normally does not allow one person to own two of the four highest-rated stations in a market. However, in its filing requesting such a waiver, Gray argued that KDLT would be in a stronger position to compete in the market if its resources were combined with those of KSFY. Gray contended that a KSFY/KDLT duopoly would fulfill "a dire need for an effective competitor" in the Sioux Falls market, where KELO-TV has been the far-and-away leader for as long as records have been kept.[5]

Digital television[edit]

Digital channels[edit]

The station's digital signal is multiplexed:

Channel Video Aspect PSIP Short Name Programming[6][7]
1080i 16:9 KDLT-DT
Main programming / NBC
480i 4:3[8] KDLT-SD
Antenna TV [9]

Analog-to-digital conversion[edit]

Both stations shut down their analog signals respectively on February 1, 2009:[10]

  • KDLT-TV shut down its analog signal, over UHF channel 46; the station's digital signal remained on its pre-transition UHF channel 47. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 46.
  • KDLV-TV shut down its analog signal, over VHF channel 5; the station's digital signal remained on its pre-transition UHF channel 26. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 5.

News operation[edit]

KDLT presently broadcasts 19½ hours of locally produced newscasts each week (with 17½ hours on weekdays and 1 hour each on Saturdays and Sundays).


Besides KDLV, the programming of KDLT is also rebroadcast on the following translator stations:
