Here you go, Skippy - thanks for station history. I learned something new today. Did not know there was a private shortwave broadcaster in NY in the 60's and that WNYW call sign had an earlier use. From Wiki:
The station adopted the slogan "Radio New York Worldwide" and used studios in New York City and an adult contemporary format, with ABC Radio or CBS Radio hourly and half-hour newscasts and from its sister station, WRFM. On-air staff from WRFM would also have separate shifts on WRUL. There were rumors that the station was being partially controlled by the Central Intelligence Agency to broadcast anti-communist propaganda.[citation needed]
On June 1, 1966, WRUL changed its call letters to WNYW, which stood for "Radio New York Worldwide". The station attempted to do some commercial programming, but there were few advertisers because it was difficult to estimate audience ratings for the wide geographical area that shortwave stations typically covered.
In 1970, Bonneville offered to sell the station to the U.S. government for a token payment of one dollar, for use by the Voice of America, but no sale materialized.[citation needed]
In 1974, Bonneville sold WNYW. The callsign would eventually be adopted by the Fox Broadcasting Company's flagship station, WNYW (formerly Metromedia station WNEW-TV and DuMont Television Network station WABD) in New York City, in 1986.
