Tranquility Base, here. The Eagle has landed. The Voice of America had the world’s largest audience ever when it reported in 46 languages man landing on the Moon. It earned trust when it reported on Watergate and the anti-Vietnam protests. In 1968, Czechs battled Soviet tanks in the streets. When Soviet troops forced a Czech dissident broadcaster to sign off, he told his audience to listen to the VOA. Czech broadcasting was never trusted again.

The phrase Voice of America (VOA) has always stood for a strong, powerful American broadcasting entity.  The United States government intended the Voice of America to provide hope to people around the world and to counteract the propaganda espoused by America’s enemies in war conflicts. In the mid 1990s the federal government began closing or consolidating some large VOA broadcasting facilities. The federal government would like to close VOA site B in Greenville, NC. I hope they choose not to for several reasons.

Recently, I toured VOA Site B and observed first hand both the magnitude of the transmitting equipment and the value its broadcasting can add to the international community. The day I arrived at VOA-B, the hundreds of acres of tall expansive antennas made you feel you were entering another planet. The father of wireless, Guglielmo Marconi, would be proud to see such a place full of great engineering and information for the world. Many wire antennas meshed together to form a tall wide curtain were supported by tall 300 feet towers. Each tower is fed by elevated transmission line (1 inch conducting pipes) 15 feet off the ground. Once inside the transmitting facility, the same degree of largeness is apparent by several “truck size” transmitters.

VOA B operates in the so called shortwave frequency band where signals radiated by the antenna reflect off the earth’s ionosphere and reach their destination hundreds or thousands of miles away – cell phones do not come close to that range! The VOA may be old by some standards but it is new to those who cherish the iron clad tube technology and massive antennas as well as those who rely on shortwave for critical and sometimes life-saving information. Let us not forget, telephone, cell towers and the related internet infrastructure is vulnerable during emergencies and disasters and the VOA’s former cold war technology is always reliable. Like an old 57 Chevy or 66 Mustang, VOA and shortwave may be antiquated but to some it is new and a look back into passion and handcraft, a breath of fresh air for those who grew up on old time radio.  There are very few electrical engineers who understand how to operate and maintain a large shortwave station like the VOA and keeping the station active is part of the educational process.

Similar to the radio announcer inside a control room, were the many knobs and switches present that allow selection of the various transmitters to broadcast news and information to an estimated 125 million people. VOA broadcasts approximately 1,500 hours of news, information, educational, and cultural programming every week to a worldwide audience, the specific country receives the signal from a specific antenna, one of many at the facility.

Inside the compound, “RF,” or radio-frequency transmitters lined the walls making up a room the size of a basketball court. Two 1950’s vintage Continental 500 KW transmitters, four 250 kilowatt shortwave transmitters and lower power units of various ages and makes; plus a dozen or more directional shortwave antennas sent programming, ultimately in many languages, skipping off the ionosphere to overcome the earth’s curvature to precisely pinpointed target areas abroad. As we peered into several transmitter rooms, the phrase “real radios glow in the dark” was mindful of large vacuum tubes with glowing filaments.

Outside, at the end of the transmitter building the transmitters feed elevated rows of parallel conductors that seem to extend out into the hundreds of acres to the neverland of wires and poles.  Rest assured when a specific antenna is selected, there is an announcement to the facility and in the outside “switch matrix room”, and hydraulic shafts move conductors from one transmission line to another.

Arrays of “curtain antennas,” strung among gigantic steel support towers, were built at VOA site B sometime around 1960. These arrays are oriented at different angles facing South America and Europe and parts of Africa. Before, the automation of the switch matrix, crews had to hustle outside in all types of weather and flip a series of handles by hand in order to change the antenna. Switches would freeze so solidly in the dead of winter that engineers had to attach lit propane torches to poles, reach up and melt the ice in order to throw them. Sudden shifts in frequency came often, too, to outfox Soviet engineers who were adroit at jamming shortwave signals.

Shortwave radio remains by far the most effective means of reaching audiences around the world, particularly in the developing countries. It is far from an outdated technology, as is sometimes alleged. Case in point is earthquake-stricken Haiti, the poorest and most underdeveloped country in the Americas. When the Haiti earthquake struck, the VOA broadcast messages in French Creole from Greenville Site B allowing desperate people to hear words of encouragement. Many people had no other means of communications.

What the original engineers and planners did at VOA B was to use the inventions that evolved from Marconi and create state-of-the-art technology that enabled professional media people to tell the truth about this great country. It’s a story they believed in – still believe in – and one that resonates with the people. The Voice of America is alive and well today. We hope the VOA Site B will stay on air for many years to come.

And, a footnote to the story:

The original Greenville VOA complex consisted of Sites “A”, “B”, and “C” which formed a triangle around Greenville. The “Edward R. Murrow” receiver and administrative Site C was decommissioned some 10 years ago and is now utilized by East Carolina University for archeology and other programs.  Site A is a twin to Site B and remains intact, but little used, about 30 miles north of site B. All three sites were once connected by a major microwave link that extended to Washington, D.C. for programming and administrative traffic.

LBA Technology provides support to the Greenville VOA in the restoration of now unobtainable transmitter spare parts to keep the old systems transmitting. Read more about LBA Technology capabilities here.

  1. Nice article.
    I had a chance to visit the Ohio VOA facility before decommissioning several years ago, it was an incredible place. Referencing the pics [above] at Greenville NC, the venues appear to be similar.
    Glad the North Carolina location is still around! A real piece of history!

  2. Unfortunately Rick, the 28,000-acre Voice of America Site B facility in Greenville, NC is on the verge of being shut down. The Broadcasting Board of Governors, which oversees all government-funded, civilian international broadcasting organizations, proposed closing VOA Site B as part of the government spending cutbacks. The broadcasting board says it wants to focus on upgrading its satellite, digital and other broadcasting technologies, and closing the Greenville VOA site would save about $3.1 million.

    VOA Site B is THE LAST shortwave site operating in the United States.

  3. Broadcasting Board of Governors wants to spend its money (OUR money) on broadcasting to the Internet. There they compete with maybe 50,000 other “Internet radio” broadcasters. On shortwave, they were among the top 2 or 3 leaders, the Big Stations. Seems foolish.

    Losing the last shortwave facility in the U.S. puts all other broadcasts in the hands of foreign countries who can turn it all off.

    Another outrage: I have heard that they plan to give VOA and other United States broadcasting over to a BRITISH company for transmission. That’s like hiring Canadians and Mexicans to guard the White House! Again, foolish!

  4. Thank you so much for this informative article.

  5. Unfortunately apart from a few hobbyists, SW listening around the world continues to shrink. As with Medium Wave, it was only a matter of time before some of the original electronic media sources fall silent.

    Greenville has served its purpose well for many years. Time to move on and concentrate where the listeners actually are.

  6. VOA has always been broadcast by foreigners! I used to work for the BBC (like in England Ok ? ) in the 60’s on Short Wave TX. MOST of what we pumped out WAS VOA !!!

  7. I was one of the 13 Engineers in the late 80s to train in Greenville Site A before spreading around the world. Sorry to learn that everything is gone. Spent many, many hours training and would have finished my career in Greenville if I had been given the chance. What a waist of money to shut down all of those new high power transmittes purchased in the 80s. We just don’t seem to learn anything in this country.

  8. […] para que  Eric, Olivia y Ramon tuvieran la especial oportunidad de visitar las instalaciones de la Voz de America situadas en el area de Greenville donde el Ing. Macon Dail nos dio un tour de las instalaciones.  […]

  9. Shortwave is horse & buggy technology. Nobody listens to shortwave anymore. Streaming on the Internet means that local stations can take the feed and broadcast locally to their communities. This is what the BBC now does across America.

    Every major SW broadcaster: BBC, Radio Netherlands, Radio Canada, Radio Australia, RAI, Deutche Welle — all of them have either severely cut back or totally eliminated shortwave broadcasting. It’s just not economical in today’s world, especially when nobody is listening.

  10. My Name is Doug Swoboda. My dad Maximillian A Swoboda was 1 of the original 8 families that moved to Greenville in 1959 to build the VOA project. He passed away in 1991 but I have many articles and memorabilia on these projects. He worked at Site C and even-though I was only 7 thru 13 years old at the time I remember going to work with him in the summer and on weekends to oversee the progress on the construction and installation of equipment. Some of the original families were Fred Blackburn. Walter Gray.Ben Jones. The Kondrackies Dee & Marge Sencindivers and Carr Moore. This was as I remember about a 27 million dollar project at the time and was a state of the are facility. It is sad to see the phasing out of these 3 sites due to more modern technology and lack of Government funding. We left Greenville and were transferred to Washington D.C. where at the studios in the HEW building he oversaw and designed the equipment for the master control center affectionately called The Bubble.

    • Doug,
      I went to Greenville in jan. 1961. I was an engineer working for Alpha- Continental Corp., from Richardson, Texas. We did the layout surveying for the many antena and towers. It was great work.
      I remember your dad and Fred Blackburn. I was on the private side.

  11. @Bill Hoisington – Ben: Read my post on the VOA website below.Did you know my dad?

  12. No, I didn’t remember your Dad.
    When did your dad
    work forVOA? I spent most of my
    time at site A. Was shipped out
    to Belize and after 48 hours
    decided living out of the country
    was not for me.

  13. Doug,

    Some of the names I remember, some of the folks I knew. John Kondracki and Carr Moore were at Greenville when I got there in early 1979.

    I had had some communications with David Sencindiver, as he and Charlie Brown at the AP office in Raleigh knew each other. Blackburn, Jones and Gray, I did not know.

    I was TDY to Greenville, when C Site was shut down and one of the last things I did was to shut down the DC power supply for the large audio console in the pit at C Site. I spent many a shift running that console.

    • Sheldon: We were in Grenville from 1959-1965. During the initial set up and construction of the VOA project. I remember the downtown office across from the court house meeting with Tom Rivers for architectural design. Nello -Teer in Kinston doing much of the excavation and rigging of the curtain antennas. I was young then but the equipment was impressive. It appears there isn’t much left of what was such a grand project is there? I often think of driving back to see what it looks like now. David Sencindiver was Dee’s son. He also had 2 daughters Debbie & Margaret. Hid wife Marge was my kindergarten teacher at St Raphael s school. Is there some type of museum in Grenville to the VOA. Fred Blackburn was the director the Site C. I remember him as the big cheese there. I saw an obituary for Carr Moore about a year or so ago. I think he was 91 when he passed away. Ben Jones also passed away there in 1963 or so, It is funny you powered those consoles down. Max helped design a lot of that equipment and oversaw their installation in the early 1960s
