After several late-night test broadcasts, using the experimental call sign 6XG, radio station KGO signed on the air on January 8, 1924, from General Electric's Oakland transformer manufacturing plant. The original two-story brick building, constructed specifically for the station on East 14th Street, was demolished sometime in the 1980s.) KGO was part of a planned three-station network comprising WGY in Schenectady, New York, and KOA in Denver, Colorado. KGO was first known as the "Sunset Station" since it was General Electric's West Coast outlet. At that time it operated with a then-impressive 1000 watts.
