Leaving the new Costco north of Cincinnati I had Google find the nearest Culver’s Burger. I was lead past the sprawling VOA Metropark, not only to a late lunch but down a rabbit hole spanning from the dawn of the Age of Radio to the Cold War to our post industrial present.
Next to the burger joint was a field populated by a 831 foot radio tower, which according to Wikipedia “WLW’s distinctive diamond-shaped antenna is featured on the official seal of the City of Mason. Designed and erected by the Blaw-Knox Tower company in 1934, it was the second of its type to be built, after WSM‘s in Nashville, Tennessee, and is one of eight still operational in the United States.”
I’d assumed it has something to do with the Voice of America, whose 600 acre broadcasting facility became the Voice of America Metropark after ceasing broadcast operations in 1994. The tower had it’s own history, however, as depicted on this historical marker:
BLAW-KNOX ANTENNA
In 1922, during the infancy of broadcast letters WLW were assigned to the station begun by. Cincinnatian Powell Crosley, Jr. The station moved its transmitting operations to Mason in 1928, and by April 17, 1934, WLW had permission to operate experimentally at 500.000 watts. Becoming the radio and only commercial station to broadcast at this superpower, WLW was formally opened at 500,000 watts by President Franklin D. Roosevelt on May 2, 1934. Using its 831-foot Blaw-Knox antenna to broadcast at ten times the power of any station, it earned the title “The Nation’s Station.” Locals reported hearing broadcasts on barbed wire fences, milking machines, rain spouts, water faucets, and radiators. The custom built transmitter, a joint venture between RCA, GE, and Westinghouse, remained in operation until March 1, 1939 when the Federal Communications Commission Communications Commission (FCC) ordered the station. to return to broadcasting at 50.000 watts
THE VOICE OF AMERICA BETHANY STATION
During the height of World War II, President Franklin Roosevelt turned to the innovative engineers of the Crosley Broadcasting Corporation to build powerful short wave radio transmitters capable of delivering broadcasts overseas. On farm fields near Crosley’s WLW facility, six 200 kilowatt transmitters and 24 directional reentrant rhombic antennas were built and on September 23, 1944, the Voice of America Bethany Station was dedicated. The first broadcast was directed at Nazi Germany and began with, “We shall speak to you about America and the war. The news may be good or it may be bad, but we will tell you the truth.” For more than fifty years, the Voice of America Bethany Station delivered “truthful news” to the people of Europe, Africa, South America, and parts of Asia… New technology and budget cuts resulted in the silencing of the Bethany Station in 1994.
As it turns out the two sites are connected in that they were created by the Crosley Broadcasting Corporation:
The company was founded by pioneer radio station operator Powel Crosley and was based in Cincinnati, Ohio. Its flagship station, WLW (AM), was first licensed in March 1922.[5] Most of its broadcast properties adopted call signs with “WLW” as the first three letters. In the 1930s, WLW had an effective power of 500,000 watts, and was the only commercial U.S. AM broadcasting station ever to be permitted to transmit regularly with more than 50,000 watts. The 500,000 watt transmissions were only allowed by the FCC in the “experimental” hours, midnight to 6:00 AM, and the signal was heard in many places, including Europe.[6]
By the 1950s, the company operated a small television network in Ohio and Indiana.[6]
During World War II, Crosley built the Bethany Relay Station in Butler County, Ohio‘s Union Township, one mile west of its transmitter for WLW, for the United States Office of War Information. It operated as many as five shortwave radio stations, using the call signs WLWK, WLWL, WLWO, WLWR, and WLWS. Many of these stations were later incorporated into the Voice of America. Crosley operated the facilities for the government until 1963…
The deserted ruins of the major Crosley manufacturing facility can still be seen on the west side of I-75, just north of the area where the Cincinnati Museum Center (previously the Union Terminal train station) is currently located and near where Crosley Field once stood.
