Voice of America MetroPark

The Voice of America's Bethany Relay Station was located in Butler County, Ohio's Union Township about 25 miles north of Cincinnati, adjacent to the transmitter site of WLW. Starting in 1944 during World War II it transmitted American radio programming abroad on shortwave frequencies, using 200,000-watt transmitters built by Crosley engineers under the direction of R.J. Rockwell. The site was developed to provide 'fallback' transmission facilities inland and away from the East Coast, where transmitters were located in Massachusetts, on Long Island in New York, and in New Jersey, all close to the ocean, subject to attack from German submarines or other invading forces.

Programming originated from studios in New York until 1954, when VOA headquarters moved to Washington.
