84-766: The Tsukuba Space Center ( TKSC ) also known by its radio callsign Tsukuba , is the operations facility and headquarters for the Japan Aerospace Exploration Agency (JAXA) located in Tsukuba Science City in Ibaraki Prefecture . The facility opened in 1972 and serves as the primary location for Japan's space operations and research programs. Japanese astronauts involved in the International Space Station are trained in part here in addition to

168-637: A general aviation flight would use the call sign November-niner-seven-eight-Charlie-Papa . However, in the United States a pilot of an aircraft would normally omit saying November , and instead use the name of the aircraft manufacturer or the specific model. At times, general aviation pilots might omit additional preceding numbers and use only the last three numbers and letters. This is especially true at uncontrolled fields (those without control towers) when reporting traffic pattern positions or at towered airports after establishing two-way communication with

252-591: A natural monopoly . The FCC controlled telephone rates and imposed other restrictions under Title II to limit the profits of AT&T and ensure nondiscriminatory pricing. In the 1960s, the FCC began allowing other long-distance companies, namely MCI, to offer specialized services. In the 1970s, the FCC allowed other companies to expand offerings to the public. A lawsuit in 1982 led by the Justice Department after AT&T underpriced other companies, resulted in

336-548: A Great Britain call sign prefix, 90 and MGY to commemorate the 90th anniversary of historic 1912 radio distress calls from MGY , the Marconi station aboard the famed White Star luxury liner RMS Titanic ). The late King Hussein of Jordan was issued a special amateur license number, JY1 , which would have been the shortest possible call sign issued by the Hashemite Kingdom of Jordan. When identifying

420-468: A call sign for broadcast stations; however, they are still required for broadcasters in many countries, including the United States. Mobile phone services do not use call signs on-air because the phones and their users are not licensed, instead the cell operator is the one holding the license. However, the U.S. still assigns a call sign to each mobile-phone spectrum license. In the United States, voluntary ships operating domestically are not required to have

504-425: A call sign or license to operate VHF radios , radar or an EPIRB . Voluntary ships (mostly pleasure and recreational) are not required to have a radio. However, ships which are required to have radio equipment (most large commercial vessels) are issued a call sign. A directory of radio station call signs is called a callbook. Callbooks were originally bound books that resembled a telephone directory and contained

588-690: A convention that aircraft radio stations (and, by extension, the aircraft itself) receive call signs consisting of five letters. For example, all British civil aircraft have a five-letter registration beginning with the letter G, which can also serve for a call sign. Canadian aircraft have a call sign beginning with C–F or C–G, such as C–FABC. wing-in-ground-effect vehicles and hovercraft in Canada are eligible to receive C–Hxxx call signs, and ultralight aircraft receive C-Ixxx call signs. In days gone by, even American aircraft used five-letter call signs, such as KH–ABC, but they were replaced prior to World War II by

672-594: A cost of $ 17.3 million per year in 1996 dollars. Prior to the Portals, the FCC had space in six buildings at and around 19th Street NW and M Street NW. The FCC first solicited bids for a new headquarters complex in 1989. In 1991 the GSA selected the Portals site. The FCC had wanted to move into a more expensive area along Pennsylvania Avenue . In 1934, Congress passed the Communications Act , which abolished

756-406: A few times a day, but this practice is becoming very rare. Argentinian broadcast call signs consist of two or three letters followed by multiple numbers, the second and third letters indicating region. In Brazil, radio and TV stations are identified by a ZY, a third letter and three numbers. ZYA and ZYB are allocated to television stations; ZYI , ZYJ , ZYL , and ZYK designate AM stations; ZYG

840-457: A geographical area, class of license, or identify a licensee as a visitor or temporary resident), and a 1-, 2-, or 3-letter suffix. In Australia, call signs are structured with a two letter prefix, a digit (which identifies geographical area), and a 2, 3 or 4 letter suffix. This suffix may be followed by a further suffix, or personal identifier, such as /P (portable), /M (mobile), /AM (aeronautical mobile) or /MM (maritime mobile). The number following

924-680: A government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations , there needed to be a way to address each one when sending a telegram . In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations on board ships at sea. These were not globally unique, so

1008-463: A one-letter company identifier (for instance, 'M' and two letters as a Marconi station ) was later added. By 1912, the need to quickly identify stations operated by multiple companies in multiple nations required an international standard ; an ITU prefix would be used to identify a country, and the rest of the call sign an individual station in that country. Merchant and naval vessels are assigned call signs by their national licensing authorities. In

1092-484: A similar brand, and the name of a broadcast station for legal purposes is normally its internationally recognised ITU call sign. Some common conventions are followed in each country. Broadcast stations in North America generally use call signs in the international series. In the United States of America, they are used for all FCC-licensed transmitters. The first letter generally is K for stations located west of

1176-410: A situation he found "perplexing". These efforts later were documented in a 2015 Harvard Case Study. In 2017, Christine Calvosa replaced Bray as the acting CIO of FCC. On January 4, 2023, the FCC voted unanimously to create a newly formed Space Bureau and Office of International Affairs within the agency, replacing the existing International Bureau. FCC chairwoman Jessica Rosenworcel explained that

1260-521: A station by voice, the call sign may be given by simply stating the letters and numbers, or using a phonetic alphabet . Some countries mandate the use of the phonetic alphabet for identification. In wartime, monitoring an adversary's communications can be a valuable form of intelligence. Consistent call signs can aid in this monitoring, so in wartime, military units often employ tactical call signs and sometimes change them at regular intervals. In peacetime, some military stations will use fixed call signs in

1344-767: Is not issued to such stations due to their unlicensed nature. Also, wireless network routers or mobile devices and computers using Wi-Fi are unlicensed and do not have call signs. On some personal radio services, such as CB, it is considered a matter of etiquette to create one's own call sign, which is called a handle (or trail name). Some wireless networking protocols also allow SSIDs or MAC addresses to be set as identifiers, but with no guarantee that this label will remain unique. Many mobile telephony systems identify base transceiver stations by implementing cell ID and mobile stations (e.g., phones) by requiring them to authenticate using international mobile subscriber identity (IMSI). International regulations no longer require

1428-401: Is organized into seven bureaus, each headed by a "chief" that is appointed by the chair of the commission. Bureaus process applications for licenses and other filings, analyze complaints, conduct investigations, develop and implement regulations, and participate in hearings . The FCC has twelve staff offices. The FCC's offices provide support services to the bureaus. The FCC leases space in

1512-683: Is used for shortwave stations; ZYC , ZYD , ZYM , and ZYU are given to FM stations. In Australia, broadcast call signs are optional, but are allocated by the Australian Communications and Media Authority and are unique for each broadcast station. Most European and Asian countries do not use call signs to identify broadcast stations, but Japan, South Korea, Indonesia, the Philippines and Taiwan do have call sign systems. Spanish broadcasters used call signs consisting of E followed by two letters and up to three digits until

1596-711: The Broadcast Decency Enforcement Act of 2005 sponsored by then-Senator Sam Brownback , a former broadcaster himself, and endorsed by Congressman Fred Upton of Michigan who authored a similar bill in the United States House of Representatives . The new law stiffens the penalties for each violation of the Act. The Federal Communications Commission will be able to impose fines in the amount of $ 325,000 for each violation by each station that violates decency standards. The legislation raised

1680-532: The Columbia Broadcasting System (CBS). The report limited the amount of time during the day and at what times the networks may broadcast. Previously a network could demand any time it wanted from a Network affiliate . The second concerned artist bureaus. The networks served as both agents and employers of artists, which was a conflict of interest the report rectified. In assigning television stations to various cities after World War II ,

1764-526: The Communications Act of 1934 and amended by the Telecommunications Act of 1996 (amendment to 47 U.S.C. §151), is to "make available so far as possible, to all the people of the United States, without discrimination on the basis of race, color, religion, national origin, or sex, rapid, efficient, nationwide, and world-wide wire and radio communication services with adequate facilities at reasonable charges." The act furthermore provides that

1848-544: The Dominion of Newfoundland government retain their original VO calls. In Mexico, AM radio stations use XE call signs (such as XEW-AM ), while the majority of FM radio and television stations use XH . Broadcast call signs are normally four or five alpha characters in length, plus the -FM , -TV , or -TDT suffix where applicable. In South America call signs have been a traditional way of identifying radio and TV stations. Some stations still broadcast their call signs

1932-644: The Federal Radio Commission and transferred jurisdiction over radio licensing to a new Federal Communications Commission, including in it also the telecommunications jurisdiction previously handled by the Interstate Commerce Commission. Title II of the Communications Act focused on telecommunications using many concepts borrowed from railroad legislation and Title III contained provisions very similar to

2016-1681: The Mississippi River and W for eastern stations. Historic exceptions in the east include KYW in Philadelphia and KDKA in Pittsburgh, while western exceptions include WJAG in Norfolk, Nebraska , and WOAI in San Antonio. All new call signs have been four-character for some decades, though there are historical three-character call letters still in use today, such as KSL in Salt Lake City; KOA in Denver; WHO in Des Moines; WWJ and WJR in Detroit; WJW-TV in Cleveland ; WBT in Charlotte; WBZ in Boston; WSM in Nashville; WGR in Buffalo; KFI ; KNX and KHJ in Los Angeles; and WGN , WLS and WLS-TV in Chicago. American radio stations announce their call signs (except for rare cases in which would interfere with

2100-566: The Radio Act of 1927 . The initial organization of the FCC was effected July 17, 1934, in three divisions, Broadcasting, Telegraph, and Telephone. Each division was led by two of the seven commissioners, with the FCC chairman being a member of each division. The organizing meeting directed the divisions to meet on July 18, July 19, and July 20, respectively. In 1940, the Federal Communications Commission issued

2184-494: The breakup of the Bell System from AT&T. Beginning in 1984, the FCC implemented a new goal that all long-distance companies had equal access to the local phone companies' customers. Effective January 1, 1984, the Bell System's many member-companies were variously merged into seven independent "Regional Holding Companies", also known as Regional Bell Operating Companies (RBOCs), or "Baby Bells". This divestiture reduced

2268-631: The "Report on Chain Broadcasting " which was led by new FCC chairman James Lawrence Fly (and Telford Taylor as general counsel). The major point in the report was the breakup of the National Broadcasting Company (NBC), which ultimately led to the creation of the American Broadcasting Company (ABC), but there were two other important points. One was network option time, the culprit here being

2352-457: The 1960s All-Channel Receiver Act ), to make UHF viable against entrenched VHF stations. In markets where there were no VHF stations and UHF was the only TV service available, UHF survived. In other markets, which were too small to financially support a television station, too close to VHF outlets in nearby cities, or where UHF was forced to compete with more than one well-established VHF station, UHF had little chance for success. Denver had been

2436-518: The 1960s when flight radio officers (FRO) were no longer required on international flights. The Russian Federation kept FROs for the Moscow-Havana run until around 2000. Currently, all signs in aviation are derived from several different policies, depending upon the type of flight operation and whether or not the caller is in an aircraft or at a ground facility. In most countries, unscheduled general aviation flights identify themselves using

2520-558: The 50 states, the District of Columbia , and the territories of the United States . The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries in North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budget of US $ 388 million. It has 1,482 federal employees as of July 2020. The FCC's mission, specified in Section One of

2604-762: The Cable Communications Policy Act of 1984, and made substantial modifications to Title VI in the Cable Television and Consumer Protection and Competition Act of 1992. Further modifications to promote cross-modal competition (telephone, video, etc.) were made in the Telecommunications Act of 1996, leading to the current regulatory structure. Broadcast television and radio stations are subject to FCC regulations including restrictions against indecency or obscenity. The Supreme Court has repeatedly held, beginning soon after

2688-522: The FCC a legal basis for imposing net neutrality rules (see below), after earlier attempts to impose such rules on an "information service" had been overturned in court. In 2005, the FCC formally established the following principles: To encourage broadband deployment and preserve and promote the open and interconnected nature of the public Internet, Consumers are entitled to access the lawful Internet content of their choice; Consumers are entitled to run applications and use services of their choice, subject to

2772-484: The FCC found that it placed many stations too close to each other, resulting in interference. At the same time, it became clear that the designated VHF channels, 2 through 13, were inadequate for nationwide television service. As a result, the FCC stopped giving out construction permits for new licenses in October 1948, under the direction of Chairman Rosel H. Hyde . Most expected this "Freeze" to last six months, but as

2856-587: The FCC in the newly created post of associate general counsel/chief diversity officer. Numerous controversies have surrounded the city of license concept as the internet has made it possible to broadcast a single signal to every owned station in the nation at once, particularly when Clear Channel, now IHeartMedia , became the largest FM broadcasting corporation in the US after the Telecommunications Act of 1996 became law - owning over 1,200 stations at its peak. As part of its license to buy more radio stations, Clear Channel

2940-437: The FCC indicated that the public largely believed that the severe consolidation of media ownership had resulted in harm to diversity, localism, and competition in media, and was harmful to the public interest. David A. Bray joined the commission in 2013 as chief information officer and quickly announced goals of modernizing the FCC's legacy information technology (IT) systems, citing 200 different systems for only 1750 people

3024-403: The FCC said that nearly 55 million Americans did not have access to broadband capable of delivering high-quality voice, data, graphics and video offerings. On February 26, 2015, the FCC reclassified broadband Internet access as a telecommunications service, thus subjecting it to Title II regulation, although several exemptions were also created. The reclassification was done in order to give

3108-534: The FCC was created "for the purpose of the national defense" and "for the purpose of promoting safety of life and property through the use of wire and radio communications." Consistent with the objectives of the act as well as the 1999 Government Performance and Results Act (GPRA), the FCC has identified four goals in its 2018–22 Strategic Plan. They are: Closing the Digital Divide, Promoting Innovation, Protecting Consumers & Public Safety, and Reforming

3192-563: The FCC's Processes. The FCC is directed by five commissioners appointed by the president of the United States and confirmed by the United States Senate for five-year terms, except when filling an unexpired term. The U.S. president designates one of the commissioners to serve as chairman. No more than three commissioners may be members of the same political party . None of them may have a financial interest in any FCC-related business. Commissioners may continue serving until

3276-514: The FCC, which regulated AT&T's long-line charges, but the commission took no action. The result was that financially marginal DuMont was spending as much in long-line charge as CBS or NBC while using only about 10 to 15 percent of the time and mileage of either larger network. The FCC's "Sixth Report & Order" ended the Freeze. It took five years for the US to grow from 108 stations to more than 550. New stations came on line slowly, only five by

3360-522: The International Space Station. 36°3′56.8″N 140°7′47.3″E  /  36.065778°N 140.129806°E  / 36.065778; 140.129806 Call sign In broadcasting and radio communications , a call sign (also known as a call name or call letters —and historically as a call signal —or abbreviated as a call ) is a unique identifier for a transmitter station . A call sign can be formally assigned by

3528-404: The Internet, cable services and wireless services has raised questions whether new legislative initiatives are needed as to competition in what has come to be called 'broadband' services. Congress has monitored developments but as of 2009 has not undertaken a major revision of applicable regulation. The Local Community Radio Act in the 111th Congress has gotten out of committee and will go before

3612-641: The Sentinel Square III building in northeast Washington, D.C. Prior to moving to its new headquarters in October 2020, the FCC leased space in the Portals building in southwest Washington, D.C. Construction of the Portals building was scheduled to begin on March 1, 1996. In January 1996, the General Services Administration signed a lease with the building's owners, agreeing to let the FCC lease 450,000 sq ft (42,000 m ) of space in Portals for 20 years, at

3696-492: The United States accelerated an already ongoing shift in the FCC towards a decidedly more market-oriented stance. A number of regulations felt to be outdated were removed, most controversially the Fairness Doctrine in 1987. In terms of indecency fines, there was no action taken by the FCC on the case FCC v. Pacifica until 1987, about ten years after the landmark United States Supreme Court decision that defined

3780-553: The United States. The FCC maintains jurisdiction over the areas of broadband access , fair competition , radio frequency use, media responsibility, public safety, and homeland security . The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the previous Federal Radio Commission . The FCC took over wire communication regulation from the Interstate Commerce Commission . The FCC's mandated jurisdiction covers

3864-591: The allocation of channels to the emerging UHF technology and the eagerly awaited possibilities of color television were debated, the FCC's re-allocation map of stations did not come until April 1952, with July 1, 1952, as the official beginning of licensing new stations. Other FCC actions hurt the fledgling DuMont and ABC networks. American Telephone and Telegraph (AT&T) forced television coaxial cable users to rent additional radio long lines , discriminating against DuMont, which had no radio network operation. DuMont and ABC protested AT&T's television policies to

3948-673: The amateur radio service as a citizen of their country has been assigned there. The first amateur radio call sign assigned to the International Space Station was NA1SS by the United States. OR4ISS (Belgium), DP0ISS (Germany), and RS0ISS (Russia) are examples of others, but are not all-inclusive of others also issued. Broadcasters are allocated call signs in many countries. While broadcast radio stations will often brand themselves with plain-text names, identities such as " Cool FM ", " Rock 105" or "the ABC network" are not globally unique. Another station in another city or country may (and often will) have

4032-438: The appointment of their replacements. However, they may not serve beyond the end of the next session of Congress following term expiration. In practice, this means that commissioners may serve up to 1 + 1 ⁄ 2 years beyond the official term expiration listed above if no replacement is appointed. This would end on the date that Congress adjourns its annual session, generally no later than noon on January 3. The FCC

4116-572: The book value of AT&T by approximately 70%. The FCC initially exempted "information services" such as broadband Internet access from regulation under Title II. The FCC held that information services were distinct from telecommunications services that are subject to common carrier regulation. However, Section 706 of the Telecommunications Act of 1996 required the FCC to help accelerate deployment of "advanced telecommunications capability" which included high-quality voice, data, graphics, and video, and to regularly assess its availability. In August 2015,

4200-539: The broadcast of very long works of classical or opera music) at or near the top of each hour, as well as sign-on and sign-off for stations that do not broadcast 24 hours. Beginning in the early 2000s, digital subchannels were assigned a -DT# suffix, where # is the subchannel (starting with the number 2). In Canada, the publicly owned Canadian Broadcasting Corporation uses the prefix CB ; privately owned commercial broadcast stations use primarily CF and CH through CK prefixes; and four stations licensed to St. John's by

4284-551: The call sign corresponding to the aircraft's registration number (also called N-number in the U.S., or tail number ). In this case, the call sign is spoken using the International Civil Aviation Organization (ICAO) phonetic alphabet . Aircraft registration numbers internationally follow the pattern of a country prefix, followed by a unique identifier made up of letters and numbers. For example, an aircraft registered as N978CP conducting

4368-1074: The case of states such as Liberia or Panama , which are flags of convenience for ship registration, call signs for larger vessels consist of the national prefix plus three letters (for example, 3LXY, and sometimes followed by a number, e.g. 3LXY2). United States merchant vessels are given call signs beginning with the letters "W" or "K" while US naval ships are assigned call signs beginning with "N". Originally, both ships and broadcast stations were assigned call signs in this series consisting of three or four letters. Ships equipped with Morse code radiotelegraphy, or life boat radio sets, aviation ground stations, broadcast stations were given four-letter call signs. Maritime coast stations on high frequency (both radiotelegraphy and radiotelephony) were assigned three-letter call signs. As demand for both marine radio and broadcast call signs grew, gradually American-flagged vessels with radiotelephony only were given longer call signs with mixed letters and numbers. Leisure craft with VHF radios may not be assigned call signs, in which case

4452-444: The commission in 1934 comprised the following seven members: The complete list of commissioners is available on the FCC website. Frieda B. Hennock (D-NY) was the first female commissioner of the FCC in 1948. The FCC regulates broadcast stations, repeater stations as well as commercial broadcasting operators who operate and repair certain radiotelephone , radio and television stations. Broadcast licenses are to be renewed if

4536-414: The conversion, Congress established a federally sponsored DTV Converter Box Coupon Program for two free converters per household. The FCC regulates telecommunications services under Title II of the Communications Act of 1934. Title II imposes common carrier regulation under which carriers offering their services to the general public must provide services to all customers and may not discriminate based on

4620-517: The country/territory identifier is, instead, appended to the call sign; e.g., W1AW/VE4, or VE3XYZ/W1. Special call signs are issued in the amateur radio service either for special purposes, VIPs, or for temporary use to commemorate special events. Examples include VO1S ( VO1 as a Dominion of Newfoundland call sign prefix, S to commemorate Marconi 's first trans-Atlantic message, a single-character Morse code S sent from Cornwall , England to Signal Hill, St. John's in 1901) and GB90MGY ( GB as

4704-515: The current American system of civilian aircraft call signs (see below). One exception to the parallelism between registration and call sign is ultralight airplanes in France, who are not obliged to carry a radio and indeed often don't. Radio call signs used for communication in crewed spaceflight are not formalized or regulated to the same degree as for aircraft. The three nations currently launching crewed space missions use different methods to identify

4788-743: The designated call sign, so F13C would be the Charlie fire team . Unused suffixes can be used for other call signs that do not fall into the standard call sign matrix, for example the unused 33A call sign is used to refer to the company sergeant major . No call signs are issued to transmitters of the long-range navigation systems ( Decca , Alpha , Omega ), or transmitters on frequencies below 10 kHz , because frequencies below 10 kHz are not subject to international regulations. In addition, in some countries lawful unlicensed low-power personal and broadcast radio signals ( Citizen's Band (CB), Part 15 or ISM bands ) are permitted; an international call sign

4872-421: The end of November 1952. The Sixth Report and Order required some existing television stations to change channels, but only a few existing VHF stations were required to move to UHF, and a handful of VHF channels were deleted altogether in smaller media markets like Peoria , Fresno , Bakersfield and Fort Wayne, Indiana to create markets which were UHF "islands." The report also set aside a number of channels for

4956-489: The end of the digital television transition. After delaying the original deadlines of 2006, 2008, and eventually February 17, 2009, on concerns about elderly and rural folk, on June 12, 2009, all full-power analog terrestrial TV licenses in the U.S. were terminated as part of the DTV transition , leaving terrestrial television available only from digital channels and a few low-power LPTV stations. To help U.S. consumers through

5040-423: The fine ten times over the previous maximum of $ 32,500 per violation. The FCC has established rules limiting the national share of media ownership of broadcast radio or television stations. It has also established cross-ownership rules limiting ownership of a newspaper and broadcast station in the same market, in order to ensure a diversity of viewpoints in each market and serve the needs of each local market. In

5124-598: The first post-Freeze construction permits. KFEL (now KWGN-TV )'s first regular telecast was on July 21, 1952. In 1996, Congress enacted the Telecommunications Act of 1996 , in the wake of the breakup of AT&T resulting from the U.S. Department of Justice's antitrust suit against AT&T. The legislation attempted to create more competition in local telephone service by requiring Incumbent Local Exchange Carriers to provide access to their facilities for Competitive Local Exchange Carriers . This policy has thus far had limited success and much criticism. The development of

5208-563: The first two digits indicate the nominal length of the boat in feet. For example, Coast Guard 47021 refers to the 21st in the series of 47-foot motor lifeboats. The call sign might be abbreviated to the final two or three numbers during operations, for example: Coast Guard zero two one . Originally aviation mobile stations (aircraft) equipped with radiotelegraphy were assigned five-letter call signs (e.g. KHAAQ). Land stations in aviation were assigned four-letter call signs (e.g. WEAL – Eastern Air Lines, NYC.) These call signs were phased out in

5292-434: The ground and space radio stations; the United States uses either the names given to the space vehicles, or else the project name and mission number. Russia traditionally assigns code names as call signs to individual cosmonauts , more in the manner of aviator call signs , rather than to the spacecraft. The only continuity in call signs for spacecraft have been the issuance of "ISS"-suffixed call signs by various countries in

5376-435: The house floor with bi-partisan support, and unanimous support of the FCC. By passing the Telecommunications Act of 1996, Congress also eliminated the cap on the number of radio stations any one entity could own nationwide and also substantially loosened local radio station ownership restrictions. Substantial radio consolidation followed. Restrictions on ownership of television stations were also loosened. Public comments to

5460-446: The identity of the customer or the content of the communication. This is similar to and adapted from the regulation of transportation providers (railroad, airline, shipping, etc.) and some public utilities. Wireless carriers providing telecommunications services are also generally subject to Title II regulation except as exempted by the FCC. The FCC regulates interstate telephone services under Title II. The Telecommunications Act of 1996

5544-509: The international series. The United States Army uses fixed station call signs which begin with W , such as WAR, used by U.S. Army Headquarters. Fixed call signs for the United States Air Force stations begin with A , such as AIR, used by USAF Headquarters. The United States Navy , United States Marine Corps , and United States Coast Guard use a mixture of tactical call signs and international call signs beginning with

5628-465: The jurisdiction of a foreign government, an identifying station pre-pends the call sign with the country prefix and number of the country/territory from which the operation is occurring. For example, W4/G3ABC would denote a licensed amateur from the United Kingdom who is operating in the fourth district of the United States. There are exceptions; in the case of U.S./Canadian reciprocal operations,

5712-527: The largest U.S. city without a TV station by 1952. Senator Edwin Johnson (D-Colorado), chair of the Senate's Interstate and Foreign Commerce Committee , had made it his personal mission to make Denver the first post-Freeze station. The senator had pressured the FCC, and proved ultimately successful as the first new station (a VHF station) came on-line a remarkable ten days after the commission formally announced
