March 17 In Radio History



In 1935...KSO-AM in Des Moines Iowa call sign is given to KWCR.


Starting in 1925, KSO was authorized to operate from Clarinda, Iowa, on October 7, 1925.  The owner of the station was the A.A. Berry Seed Company. KSO was assigned the frequency of 241.8 meters (1240 kc) with a power of 500 watts. A used 500 watt Western Electric Transmitter was acquired from WHO, Des Moines. The first KSO broadcast was on November 2, 1925. The station used the slogan, "Keep Serving Others".

In 1927 KSO was moved to 1320 kc. Then, in the great revision of frequency assignments which occurred on November 11, 1928, KSO moved to 1380 with 1,000 watts power, but it had to share the frequency with WKBH, LaCrosse, Wisconsin. On January 18, 1929, KSO was ordered to reduce power to 500 watts; then, the share time order ended on February 28, 1931.

Iowa Broadcasting Co. entered into KSO's history in 1931 when it purchased the station from the Barry Seed Co. Iowa Broadcasting had been formed by Gardner and Mike Cowles, the newspaper publishing brothers who owned the Des Moines Register and Tribune, Minneapolis Star, and Look magazine. The sale from Barry Seed Co. to Iowa Broadcasting occurred on June 26, 1931.

For about a year KSO remained in Clarinda under Iowa Broadcasting ownership. One June 4, 1932, authority was received to suspend operations until October 1, 1932. The FRC granted permission in September 1932 for Iowa Broadcasting to move KSO to Des Moines. KSO returned to the air with studios and transmitter at the Register and Tribune building in downtown Des Moines on November 5.1932, but with a reduced power. KSO was now authorized to use 100 watts.

Note: On-Air Signs for KRNT and KSO
Major changes on March 17, 1935: KSO gained a sister station in Des Moines, KRNT, on March 17, 1935. To accommodate the new station, KSO moved to 1460 kc, a frequency previously used by KWCR, Cedar Rapids. KWCR was also owned by Iowa Broadcasting.

On September 11, 1989, the KSO call letters were retired.

Today, 1460 is owned by iHeartMedia. In early 2001, the call letters were changed to KXNO, and 1460 became an all sports station, featuring the Fox Sports Network.




In 1978…The fictionalized account of the early days of disc jockey Alan Freed, "American Hot Wax," widely considered to be one of the best rock 'n' roll movies of all time, opened in North American theaters, featuring appearances and performances by Jerry Lee Lewis, Chuck Berry, and Screamin' Jay Hawkins. Tim McIntire played Freed. Fran Drescher, Jay Leno, Laraine Newman, and Jeff Altman were also in the cast.


In 1989...WABC 770 AM moved to 2 Penn Plaza in NYC.
