The International Broadcasting Bureau Greenville Transmitting Station is the transmitting station for Voice of America, in Greenville, North Carolina. It is also known as the Edward R. Murrow Transmitting Station or Voice of America Greenville Transmitting Station. Originally at three sites, only one, site B, is in current use. Greenville was chosen because of its remoteness from other communication services, proximity of large quantities of reliable electric power, type of terrain and suitability for construction, and availability of property [1] which ensured the best electronic propagation conditions. [2] The transmitting station provides shortwave broadcasts for U.S. government-funded, nonmilitary and international broadcasting. The main target areas for the station's shortwave broadcasts are Latin America, Cuba, the Caribbean, North Africa, and Africa.
In the early 1950s, VOA planned for the construction of a high-power shortwave complex on the East Coast of the United States to provide coverage to Europe, Africa, and South America. By 1954, the project was suspended, but the need continued to grow. The transmitters in Wayne, New Jersey, and Brentwood and Schenectady, New York continued to become more inadequate every year. Congress gave approval for a new transmission station in 1958. That same year site exploration found 38 potential locations. Final selection was made a year later, and the land was acquired. The site had to be south enough to avoid the northern auroral zone, but close enough to Washington D.C. to keep transmitting cost to a minimum. Because of the number of transmitters needed, it was decided to split the transmission site into two, site A and site B. The receiving facilities, program master control, communications center, and station main offices were located at site C. [3] Construction began on February 15, 1960 and was completed December 7, 1962, at a cost of $23–24 million. All three stations were dedicated by President John F. Kennedy and became operational on February 8, 1963. [2] [3] [4] The new facilities doubled the VOA's power and employed 100 people around the clock. [2] The cost was offset by the closure of the transmitters in Wayne, Brentwood, and Schenectady. From January 1988 until mid-1997, the station was the network training facility for new Foreign Service Officers, who spent six months in training at the stations prior to being sent overseas. [5] The Greenville facilities became the most powerful international broadcaster in the world, in both physical size and radio frequency energy. [3] Each of the sites housed nine transmitters – three of 500,000 watts, three of 250,000 watts, and three of 50,000 watts. [6]
President John F. Kennedy's remarks at the dedication ceremony for the United States Information Agency Transmitter Complex in Greenville, North Carolina
- It gives me great pleasure to open this dedication of a new transmitter complex of the United States Information Agency. Today is the beginning. More peoples in many new lands will now hear the sound of the voice of this country, the Voice of America.
- The radio arm of the United States Information Agency helps to tell America's story abroad. The Voice of America is young in years, but it is experienced in deeds. These powerful new transmitters at Greenville symbolize an advance into a new dimension of responsibility.
- The years ahead hold the promise of our telling America's story to people unable to hear it now. Today the voice is strong where once it was weak. Today the Voice of America can better reach those whose masters seek to drown it out with jamming and interference. It is the truth of ideas that this new facility will communicate to an eager world.
- A man may die, nations may rise and fall, but an idea lives on. Ideas have endurance without death. In this dawn of the Space Age, Telestar and Relay share the future with these transmitters. Telestar and Relay cannot broadcast directly into a home, but these shortwave transmitters do.
- Both they and the satellites will tomorrow help tell our story to the world. To the United States Information Agency I say congratulations to the new Greenville facility. Your burden in the years ahead is one of truth and challenge. I am confident it will be well discharged and free men everywhere will listen to the sound of your words of truth that seek out men and women of the world that wish to listen to the voice of freedom, to the Voice of America

Site C originally had 633 acres (256 ha) near Falkland, North Carolina. This site is the only receiving station in the area. In 1968, this station was rededicated as Edward R. Murrow Transmitting Station, in honor of Edward R. Murrow, former director of the United States Information Agency. In 1971, a private agribusiness, with the help of a local congressman, buried toxic waste from a fire at a chemical storage warehouse. Personnel stopped using the site in 1985. In 1987, the site became a gateway Earth station for the Global Satellite Interconnect System. In 1994, the General Services Administration sold the site, minus 55 acres (22 ha) that contained the toxic waste, to the State of North Carolina and local governments. The site closed on March 31, 1995, due to budget reductions and changes in technology. In 1998, satellite dishes were placed on the Cohen Building in Washington, D.C. Greenville then became a receive-only station and acted as a backup to the headquarters site. [5] It was decommissioned in 1999 and sold to East Carolina University in 2001. [2] Today the land is used by the Department of Biology for research and ROTC for training. [14] There are seven buildings with 33,000 square feet (3,100 m2) of space. [15] Also, the main office of the North Carolina Agromedicine Institute, and a facility for the Office of State Archaeology. Blackbeard's flagship, Queen Anne's Revenge artifacts are being restored there. [2]
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz ; above the medium frequency band (MF), to the bottom of the VHF band.
Voice of America is the state-owned news network and international radio broadcaster of the United States of America. It is the largest and oldest of the U.S.-funded international broadcasters. VOA produces digital, TV, and radio content in 48 languages, which it distributes to affiliate stations around the world. Its targeted and primary audience is non-American.
International broadcasting, in a limited extent, began during World War I, when German and British stations broadcast press communiqués using Morse code. With the severing of Germany's undersea cables, the wireless telegraph station in Nauen was the country's sole means of long-distance communication.

Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz. Listeners range from casual users seeking international news and entertainment programming, to hobbyists immersed in the technical aspects of radio reception and collecting official confirmations that document their reception of distant broadcasts (DXing). In some developing countries, shortwave listening enables remote communities to obtain regional programming traditionally provided by local medium wave AM broadcasters. In 2002, the number of households that were capable of shortwave listening was estimated to be in the hundreds of millions.
Shortwave broadcasting in the United States allows private ownership of commercial and non-commercial shortwave stations that are not relays of existing AM/MW or FM radio stations, as are common in Africa, Europe, Asia, Oceania except Australia and Latin America. In addition to private broadcasters, the United States also has government broadcasters and relay stations for international public broadcasters. Most privately owned shortwave stations have been religious broadcasters, either wholly owned and programmed by Roman Catholic and evangelical Protestant charities or offering brokered programming consisting primarily of religious broadcasters. To better reach other continents of the world, several stations are located in far-flung US territories. Shortwave stations in the USA are not permitted to operate exclusively for a domestic audience; they are subject to antenna and power requirements to reach an international audience.
The Voice of America's Bethany Relay Station was located in Butler County, Ohio's Union Township about 25 miles (40 km) 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.
Radio jamming is the deliberate jamming, blocking or interference with wireless communications. In some cases, jammers work by the transmission of radio signals that disrupt communications by decreasing the signal-to-noise ratio.
HCJB, "The Voice of the Andes", was the first radio station with daily programming in Ecuador and the first Christian missionary radio station in the world. The station was founded in 1931 by Clarence W. Jones, Reuben Larson, and D. Stuart Clark. HCJB now focuses on Ecuador with unified programming on FM at 89.3 MHz in Pichincha, at 92.5 MHz in Manabí, at 96.1 MHz in Tungurahua and Cotopaxi, at 98.3 MHz in Esmeraldas and with separate programming on AM at 690 kHz. Broadcasts in Spanish and indigenous languages on 6.05 MHz (1 kW), continue on an intermittent basis with a new solid state transmitter which in 2017 replaced an older (5 kW) transmitter. These broadcasts were not listed on the HCJB English website as of February 2016.

A radiogram is a formal written message transmitted by radio. Also known as a radio telegram or radio telegraphic message, radiograms use a standardized message format, form and radiotelephone and/or radiotelegraph transmission procedures. These procedures typically provide a means of transmitting the content of the messages without including the names of the various headers and message sections, so as to minimize the time needed to transmit messages over limited and/or congested radio channels. Various formats have been used historically by maritime radio services, military organizations, and Amateur Radio organizations.
Radio jamming in China is a form of censorship in the People's Republic of China that involves deliberate attempts by state or Communist Party organs to interfere with radio broadcasts. In most instances, radio jamming targets foreign broadcasters, including Voice of America (VOA), Radio Free Asia, the BBC World Service, Sound of Hope (SOH) and stations based in Taiwan.
Curtain arrays are a class of large multielement directional radio transmitting wire antennas, used in the shortwave radio bands. They are a type of reflective array antenna, consisting of multiple wire dipole antennas, suspended in a vertical plane, often in front of a "curtain" reflector made of a flat vertical screen of many long parallel wires. These are suspended by support wires strung between pairs of tall steel towers, up to 90 m high. They are used for long-distance skywave transmission; they transmit a beam of radio waves at a shallow angle into the sky just above the horizon, which is reflected by the ionosphere back to Earth beyond the horizon. Curtain antennas are mostly used by international short wave radio stations to broadcast to large areas at transcontinental distances.
