KKSU was a radio station in Manhattan, Kansas from 1924 to 2002. It broadcast on the AM dial at 580 kHz. The station owned by Kansas State University and operated by K-State Research and Extension, with studios and transmitter on KSU's campus in Manhattan. At the time it signed off for good, it was part of one of the last shared-time frequencies in the United States.
History
KKSU signed on for the first time on December 1, 1924 as KSAC. The call letters came from Kansas State's name at the time, Kansas State Agricultural College. It originally broadcast at 500 watts at 880 kHz. The station was one of the first of several AM stations signed on by Midwestern land-grant colleges in the early days of broadcasting, among them Iowa State's WOI, Iowa's WSUI, Michigan State's WKAR and North Dakota's KUND. The school's extension agents saw radio as a natural extension of the school's agricultural services. In 1927, KSAC moved to 900 kHz, and the next year, it was allocated 580 kHz. KSAC and WSUI shared time on 580 kHz in late 1928 and most of 1929. A year later, SenatorArthur Capper, publisher of Topeka's daily newspaper, the Topeka Daily Capital, asked Kansas State to share the 580 frequency with his new station, WIBW. Kansas State agreed, realizing that it could not afford to stay on the air for 24 hours a day. In 1948, KSAC boosted its broadcasting power to 5,000 watts, matching its commercial partner. Due to its location on the lower end of the AM dial, this gave it coverage of most of the state. The station was off the air at the end of 1950 and early 1951 after losing its transmitter to fire. KSAC wanted to change its call letters to KKSU in 1984, almost 30 years after gaining university status. However, a mothballed Merchant Marine ship owned those calls and wasn't willing to give them up. As a stopgap, the station changed its calls to its second choice, KEXT on July 26, but continued efforts to get its preferred calls; as the KEXT call letters were assigned, the KKSU call sign became available. Finally, it was able to get the KKSU call sign on July 30. The KSAC call letters were sold for $25,000 to a station in Sacramento, California. By the mid-1990s, KKSU was on the air from 12:30 pm to 5:30 pm Central Time every weekday, airing livestock reports, agricultural updates, and news programming. For several years, it also had a daily hour of recorded classical music called Music From the Masters.
Demise
WIBW tried several times over the years to buy full control of the 580 frequency, especially after 1957, when Oscar Stauffer bought the Daily Capital Despite tremendous political pressure, KSAC/KKSU stayed on the air. In December 2001, Kansas State decided to move its sports broadcasts to the Mid-America Ag Network after airing them on WIBW continuously since 1969 and off-and-on since the 1950s. WIBW countered by citing a 1969 amendment to the timeshare agreement. That amendment granted WIBW the right to broadcast Wildcat football in exchange for allowing KKSU to extend its operating hours an additional 15 minutes each weekday. After heated negotiations, WIBW's owner, Morris Communications agreed to ignore the agreement if KKSU would give it full control of the 580 frequency. On August 29, Morris agreed to buy KKSU's timeslot for $1.5 million. In return, it agreed to give exclusive rights to all Wildcat sporting events to MAAN. KKSU went off the air for the last time on November 27, 2002. For decades KKSU had mailed radio programs and features to stations across the nation. That service was called the "K-State Radio Network." After KKSU ceased broadcasting, the former KKSU staff continued to operate the network service while at the same time starting to build a satellite uplink by which to distribute its offerings to . The site was licensed in July, 2003, and a couple of months later the daily program "" began delivery to stations wishing to air it. The continues to produce and distribute agricultural news, family and public affairs programming to radio stations and networks across the Midwest.
