KDLT-TV is the NBC-affiliated television station in Sioux Falls, South Dakota, serving Eastern South Dakota and Southwestern Minnesota. The station broadcasts its digital signal on UHF channel 47, which remaps to analog channel 46 via PSIP. It also operates a full-powered satellite station: KDLV-TV in Mitchell, South Dakota (digital channel 26, virtual channel 5). KDLT's 2,000 feet (610 m) transmitter tower is located near Rowena.


In 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. 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.

In 1972, the station changed its calls to KXON-TV. 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 once again getting NBC. At the time of the switch KSFY had three full-power transmitters to KDLT's one and ABC was the #1 network with NBC in third, making it logical for the more popular network to align with a station with better coverage. The next year NBC and ABC ratings flip-flopped leaving KDLT once again affiliated with the more popular network. akotaland Broadcasting eventually sold KDLT to Heritage Broadcasting in 1985. Heritage Broadcasting became Heritage Media in 1987 when it acquired Rollins Telecasting. The station eventually moved its main studio to Sioux Falls in the mid to late 1980s.

Heritage Media sold KDLT to its 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]

Analog-to-digital conversion[edit]

KDLT-TV & KDLV-TV shut down their analog signals, respectively over UHF & VHF channels 46 & 5, on February 1, 2009. Both stations' digital signals remained on their pre-transition UHF channels 47 & 26.[8] Through the use of PSIP, digital television receivers display both stations' virtual channels as their former UHF & VHF analog channels 46 & 5.


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