WKNO-FM began operations in 1972, as a single station broadcasting at 40,000 watts. The studios were first located on the main campus of Memphis State University. In 1979, the WKNO-FM and TV studios were relocated a few blocks to the south, to the southern annex of MSU on Getwell Road. That facility served the television and radio stations for 30 years until November 2009, when they moved into custom-designed all-digital studios, located in the Memphis suburb of Cordova. As with many public radio outlets started during that era, programming in the early years consisted almost entirely of classical music. NPR news broadcasts did not become a significant portion of the daily schedule until well into the 1980s. The station increased its power during that period to a full 100,000 watts, thereby increasing its listenership with a stronger, clearer signal. As the popularity of public radio developed, the MSPCF decided to aggressively construct and acquire transmitters throughout the region, much of which had never been served by public radio before. It started by purchasing the broadcasting equipment of WNJC-FM, the defunct campus radio station of Northwest Mississippi Community College in Senatobia, about 40 miles south of Memphis, in 1989. MSPCF kept that station's original call sign for a few years, before rechristening it to WKNA-FM, making it conform to the mother station's pattern. That station broadcast at 88.9 MHz. Next, the board set its sights on Tennessee's largest city without any public radio service, Jackson, and in 1990 started a repeater, WKNP. Finally, in 1993, WKNO-FM solidified its coverage of West Tennessee with a repeater serving northwestern Tennessee and southeastern Missouri, WKNQ. Situated in the town of Dyersburg, that station broadcast at 90.7 MHz. For a few years, the stations broadcast identical programs, except for daytime coverage of Memphis city council meetings, which were heard only on the mother station. In some portions of the listening area, particularly that of WKNA-FM, competing stations such as Mississippi Public Broadcasting duplicated some network offerings as well. Eventually, however, with the great expansion of public radio news and talk programming in the late 1990s, MSPCF decided to take advantage of it by splitting the network into two. With that, the Memphis and Jackson stations programmed classical music during the middle of the day and at night, news and information during rush hour, and weekly feature programs on the weekends. Meanwhile, the Dyersburg and Senatobia frequencies carried news, talk, and information shows from various public radio packagers and the BBC. On occasion, the four stations aired the same programming.
2007 translator sale
In early 2007, WKNO/MSPCF sold the Senatobia and Dyersburg stations, WKNA and WKNQ, to Christian broadcasters, with the American Family Association buying WKNA for the American Family Radio talk network, and the Educational Media Foundation buying WKNQ for its K-LoveCCM network. MSPCF president Michael LaBonia said that WKNO's hopes to expand the coverage areas of the two stations were unsuccessful. He stated that WKNA's signal was barely listenable in northern Mississippi outside of a small radius, not even getting into metro Memphis, which led to the sale of the frequencies. The sale left the northwestern corner of Tennessee as one of the few areas in the U.S. without a clear signal from an NPR station, the closest signal being Murray, Kentucky's WKMS. According to the Memphis Flyer, MSPCF netted some $2.8 million from the transaction with the religious networks. The coverage areas of WKNA and WKNQ also held a much smaller base of listener support than the core area WKNO/WKNP served due to their more rural coverage areas.
Current schedule
After the sale, WKNO/WKNP reconfigured its schedule to match most public radio stations, while still providing significant hours of classical music. The new lineup features NPR newscasts throughout the day; NPR news magazines, such as All Things Considered and Morning Edition in morning and afternoon drive time slots; Marketplace from American Public Media in the late afternoons; Fresh Air in the early evening; with local programming during the daytime on weekends, as well as the Metropolitan Opera broadcasts, and several lighthearted shows from NPR, APM, and PRI. Classical music is heard at other times.
HD Radio services
In late 2007, WKNO/WKNP began broadcasting digitally, so listeners with an HD radio are able to receive three streams. The first stream is a simulcast of the analog signal. A second stream alternates between NPR and American Public Media shows when classical music is broadcast on the first stream, and classical music when the first stream broadcasts NPR, PRI and APM spoken-word programming. The third stream offers 24/7 news from the BBC World Service, something previously available on WKNA and WKNQ.
