KMOS-TV

KMOS-TV signed on July 8, 1954, as KDRO-TV, owned by Milt Hinlein along with KDRO radio. The calls came from the Drolich brothers, the radio station's original owners. The station was originally an independent.{{cite news|url=https://www.newspapers.com/clip/69231391/kdro-tv-makes-debut-thursday-night-in/|accessdate=February 10, 2021|page=1|work=Sedalia Democrat|date=July 9, 1954|title=KDRO-TV Makes Debut Thursday Night In Big Opening Program}}

KDRO-TV went through several partial changes in ownership in the late 1950s. In July 1955, Deare Publications, publisher of the Sedalia Democrat newspaper, purchased 50% of KDRO-AM-TV from Hinlein.{{cite news|url=https://www.newspapers.com/clip/69231561/half-interest-in-radio-tv-bought-here/|accessdate=February 10, 2021|page=1|title=Half Interest In Radio-TV Bought Here|date=February 24, 1955|work=Sedalia Democrat}} In July 1957, Jimmy Glenn and Herb Brandes purchased a two-thirds interest in KDRO radio; Hinlein became the sole owner of KDRO-TV as Deare Publications became the owner of the KDRO studio properties.

In November 1957, Hinlein sold one-half interest in KDRO-TV to several station employees, who took over the operation of the station. On July 20, 1958, KDRO-TV became an ABC affiliate. ABC refused to give it a network feed to protect the rights of Kansas City's main ABC affiliate, KMBC-TV (channel 9). Station engineers switched to and from KMBC-TV's signal whenever ABC network programming was on the air. Cook Paint and Varnish Company, owner of KMBC-TV, then bought KDRO-TV on January 28, 1959, and changed the call letters to the current KMOS-TV.{{cite news|url=https://www.newspapers.com/clip/69231253/call-letters-of-channel-6-change-today/|accessdate=February 11, 2021|title=Call Letters Of Channel 6 Change Today|date=February 6, 1959|work=Sedalia Democrat|page=1}} The station used the slogan "For the very MOST in entertainment!", with the KMOS-TV call letters being used to emphasize the word. It then became a full-time satellite of KMBC-TV. The station had always found the going difficult due to a limited viewer base, and becoming a full satellite of KMBC-TV ensured its survival.

In December 1960, Cook Paint sold KMBC-TV to Metropolitan Broadcasting (later called Metromedia). Metropolitan Broadcasting did not want KMOS, so it sold channel 6 to the Jefferson City News Tribune, owner of Mid-Missouri's CBS affiliate, KRCG (channel 13).{{cite news|url=https://www.newspapers.com/clip/69230803/sale-of-kmos-tv-is-announced-here/|title=Sale of KMOS-TV Is Announced Here|date=December 23, 1960|work=Sedalia Democrat|page=1|accessdate=February 11, 2021}} KMOS then became a semi-satellite of KRCG. It simulcast KRCG for most of the day but maintained the studio in Sedalia and would break away from KRCG for its own newscasts at 6 and 10 p.m.{{cite news|url=https://www.newspapers.com/clip/69244713/new-owners-of-kmos-tv-take-charge/|accessdate=February 11, 2021|title=New Owners Of KMOS-TV Take Charge|page=1, [https://www.newspapers.com/clip/69244727/new-owners/ 2]|work=Sedalia Democrat|date=August 29, 1961}} In July 1966, KMOS and KRCG were sold to Kansas City Southern Industries, the parent company of the Kansas City Southern Railroad.

By the mid-1960s, Mid-Missouri was just barely large enough for three full network affiliates. However, KRCG and NBC affiliate KOMU-TV (channel 8) in Columbia were the only VHF network affiliates in the Columbia/Jefferson City market, and wanted to keep it that way. With this in mind, KRCG operated KMOS at a fairly low power level and turned down all offers to sell it to another commercial owner, not wanting to chance on the new owner making KMOS a full-power ABC affiliate. The area did not have a full-time ABC affiliate until Columbia's KCBJ-TV (now KMIZ) signed-on in 1971.

In 1978, Kansas City Southern Industries donated KMOS to Central Missouri State University (now the University of Central Missouri), who converted the station into a stand-alone PBS station; some local interests had expressed dismay at the loss of Sedalia's commercial television station.{{cite news|url=https://www.newspapers.com/clip/69230715/cmsu-gets-grant-to-buy-kmos/|pages=1, [https://www.newspapers.com/clip/69230744/cmsu-kmos/ 4]|work=Sedalia Democrat|title=CMSU gets grant to buy KMOS|date=January 6, 1978}} Previously, Columbia/Jefferson City had been one of the few areas of Missouri without its own PBS member station. Most cable systems in the market piped in KETC, while the western part of the market could also get a grade B signal from KCPT. Central took control of KMOS on August 15, 1978, and took it off the air for 16 months to give it a significant technical overhaul. It returned to the air on December 22, 1979, from new studios in Warrensburg. After relinquishing KMOS, KRCG started a translator station in Sedalia, K11OJ.

The KMOS transmitter had an effective radiated power of 100 kW for its channel 6 analog frequency, but has 322 kW for its digital channel (corresponding to the bandwidth of channel 15), with similar height above average terrain for both transmitters (about {{convert|602|to|603|m|ft|0|disp=sqbr|sp=us}} above sea level).

The station's digital signal is multiplexed:

KMOS-TV shut down its analog signal, over VHF channel 6, on April 2, 2009. The station's digital signal remained on its pre-transition UHF channel 15, using virtual channel 6.{{cite web|url=http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf |title=DTV Tentative Channel Designations for the First and the Second Rounds |access-date=March 24, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20130829004251/http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf |archive-date=August 29, 2013 }}

In April 2003, opening ceremonies were conducted for the station's new digital broadcasting and transmitter facility in Syracuse, Missouri, located about {{convert|50|mi|km}} from Warrensburg, and includes a {{convert|2000|ft|m|0|adj=on}} guyed mast, the KMOS TV Tower (also called a Rohn tower). It was built 2001–2002 and was inaugurated on April 24, 2003. The tower is the tallest structure in Missouri and one of the tallest structures in the world—more than three times the height of the Gateway Arch. The tower is {{convert|0.2|m|ft}} higher than the previous record holder KYTV (TV) in Springfield, Missouri.[http://skyscraperpage.com/diagrams/?searchID=45979436&offset=0 Skyscraper.com - Retrieved February 15, 2010]
