From the Arkansas Gazette (purchased by the Democrat) and the Arkansas Democrat, are two press accounts of KAAY's envolvement.
Now more of the the paper from Richard Robinson (see below):
That Monday night nine stations, including two commercial shortwave stations, WRUL in New York, New York, and KEGI in San Carlos, California participated in the broadcast efforts for the government (Sorensen, 1968. New York Times, 1962).
Seven commercial medium wave stations carried the president's speech that evening. They included stations WGBS, WMIE, and WCKR in Miami, Florida; WSB in Atlanta, Georgia; WCKY in Cincinnati, Ohio; WKWF in Key West, Florida; and WWL in New Orleans, Louisiana. An eighth station -- KAAY in Little Rock, Arkansas -- joined the network on Wednesday (October 25, 1962), and began broadcasting the Voice of America programs from 11 p.m. until dawn, the period when their signal reaches into Cuba. KAAY asked to join the network ("U.S. Blanket of Words...", Kansas City Star, October 26, 1962).
This was the first time in history that private radio stations in the United States had cooperated with the government to broadcast programs from its own propaganda agency to a foreign country (USIA, 1983).
