KOZK

KOZK's history can be traced to the founding of Springfield Community Television, a nonprofit group that was formed in 1974 to bring public television to the area. At the time, it was standard practice for PBS to offer its programming to commercial television outlets in markets without a PBS station of their own. For instance, NBC affiliate KYTV (channel 3) aired Sesame Street at 9:00 a.m. during the week. After securing a license from the Federal Communications Commission (FCC) and funding from various groups, Springfield Community Television was able to launch its first station. KOZK first signed on the air on January 20, 1975, broadcasting from a former Naval Reserve center located on the campus of Drury University. From there, the station originally broadcast five days a week with seven employees on its staff (augmented by a lot of student volunteerism), eventually expanding to a 24-hour operation with 25 employees. The station borrowed transmitter space from Springfield CBS affiliate KOLR (channel 10).

On June 1, 1986, KOZJ signed on from Joplin as KOZK's sister station. Its business offices are located in downtown Joplin, with its broadcasting equipment located at Missouri Southern State University. Prior to that station's sign-on, the Joplin–Pittsburg market had been one of the few markets in the United States that did not have a PBS member station of their own, although PBS programming could be received over the air via KOED-TV (in the southwestern portion of the market), KTWU-TV (in the northwestern portion), or via KOZK (in the eastern portion).

In 1990, the station moved its operations to the new Shewmaker Communications Center on the campus of Drury College. In 2001, the board agreed to sell the station to Southwest Missouri State University (now Missouri State University); later that year, the station's operations moved to Strong Hall on the MSU campus. Two years later, in 2003, KOZK moved its transmitter facilities to a 1,980-foot (600 m) broadcast tower located on Switchgrass Road in rural southwestern Webster County (north of Fordland), which was donated to the university by KYTV station management.

On April 19, 2018, at about 9:32 a.m., the KOZK transmission tower collapsed as maintenance was being done on the structure. The maintenance involved upgrades to the tower in preparation for the station's upcoming allocation shift under the spectrum repack. The six-person maintenance crew employed with Columbia, South Carolina-based Tower Consultants Inc., who were working replacing crossbeams at about the 105-foot (32 m) mark of the tower as they began to realize that the tower had likely become structurally unstable, were vacated the tower shortly before it collapsed. One worker, 56-year-old Stephen Lamay, died from injuries sustained when he became trapped under the tower debris. Three other workers were transported to area hospitals with non-life-threatening injuries and were subsequently released.[3]

While KOZK's signal was off the air, it continued to be available to Mediacom subscribers via a direct auxiliary feed transmitted by fiber optic to the cable provider; service was restored to AT&T U-verse and DirecTV customers by April 20, while it was unavailable on Dish Network (as of April 23, 2018). The tower was also used by local NOAA Weather Radio station WXL46, whose signal also went off-air.[4][5][6][7]

In March 2020, KOZK and KOZJ added World Channel to 21.4 and 26.4, respectively.
