KXOK (630 AM) was a radio station in St. Louis, Missouri, which helped pioneer the Top 40 radio format in the early-1950s. But long before that, it was the subject of a prolonged legal battle in the mid-1930s, which nearly prevented it from going on the air at all.
In its heyday as a top-40 station, KXOK broadcast on the 630 kHz frequency with 5,000 watts of power and reached a substantial portion of eastern Missouri and southern Illinois during daytime hours. At night, the power was 5,000 watts as well, but with a more directional signal, sending a strong signal into the immediate St. Louis metro area, from KXOK's three tower site just outside Granite City, Illinois.
In 1935, Elzey Roberts, publisher of the St. Louis Star-Times, applied for a license to put a new radio station on the air. He already owned station KFRU in Columbia, MO, and wanted a station in the larger St. Louis market. But his license request was challenged by two other stations in the market, KSD and WIL; the legal battle dragged on until late 1937, when the court granted Roberts' request and the FCC assigned the KXOK call letters. WIL decided to appeal, but in late March 1938, they lost. KXOK was given permission to begin building the new station. New General Manager Ray V. Hamilton announced the station would be dedicated in mid-August 1938, but there were further delays in building it. KXOK finally made its debut on September 19, 1938. Allen Franklin was the first Program Director; he came from station WLW in Cincinnati. Among the air staff was Paul Aurandt, who came there from KOMA in Oklahoma City-- he would later become famous as Paul Harvey. KXOK began its life at 1250 kc and was affiliated with the Mutual Network. But on October 26, 1940, it moved to the 630 location on the AM dial, and became affiliated with NBC Blue (later called the Blue Network). Elzey Robert continued to own the station until 1954, when his son Elzey Roberts Jr. and an associate, Chester L. Thomas, took it over.
In early November 1960, the station changed hands, when Roberts and Thomas sold the station to Robert and Todd Storz, for the sum of $1.5 million. The station changed format not long after to a new Top 40 sound. Nicknamed "The Sound and the Spirit of St. Louis" and "The Fun Spot," KXOK was one of several stations owned by Todd Storz as part of the Storz family of stations (other stations in the group included WHB across the state in Kansas City, WQAM in Miami, WTIX in New Orleans, KOMA in Oklahoma City, and WDGY in Minneapolis-St. Paul). During the mid-60's KXOK was one of the two dominant radio stations in the St. Louis market, along with KMOX. KXOK was so successful during this period, that its Top 40 competitor, WIL (AM 1430) dropped pop music in 1967, and switched to country music. [1]
