List Of AM-band Radio Station Lists Issued By The United States Government
List of AM-band radio station lists issued by the United States government is a review of the official AM-band station lists prepared by U.S. regulators. Table information In the United States, radio station regulation has been the responsibility of the following agencies: * Department of Commerce (DOC) (1912–1927) * Federal Radio Commission (FRC) (1927–1934) * Federal Communications Commission (FCC) (1934+) In the list below, under the Listed by heading, "Zone" refers to the five regional zones established by the provisions of the Davis Amendment, which was in force from 1928 to 1936. Under the Source heading, "RSB" refers to the ''Radio Service Bulletin'', published until June 1932 by the Department of Commerce, from July 1932 until July 1934 by the Federal Radio Commission, and thereafter by the Federal Communications Commission. The annual issues of ''Commercial and Government Radio Stations of the United States'' were all published by the Department of Commerce. Referenc ...

Federal Radio Commission
The Federal Radio Commission (FRC) was a government agency that regulated United States radio communication from its creation in 1927 until 1934, when it was succeeded by the Federal Communications Commission (FCC). The FRC was established by the Radio Act of 1927, which replaced the Radio Act of 1912 after the earlier law was found to lack sufficient oversight provisions, especially for regulating broadcasting stations. In addition to increased regulatory powers, the FRC introduced the standard that, in order to receive a license, a radio station had to be shown to be "in the public interest, convenience, or necessity". Previous regulation Radio Act of 1912 Although radio communication (originally known as "wireless telegraphy") was developed in the late 1890s, it was largely unregulated in the United States until the passage of the Radio Act of 1912. This law set up procedures for the Department of Commerce to license radio transmitters, which initially consisted primarily of ...

Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across 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 Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers 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 of 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Davis Amendment
The Davis Amendment was a provision attached to the March 28, 1928 reauthorization of the Radio Act of 1927, which mandated an "equality of radio broadcasting service" within the United States. It specified an "equitable allocation" among five regional zones, in addition to assignments proportional to population among the states within each zone. Its implementation resulted in the development of a complicated quota system by the Federal Radio Commission, and although its provisions were carried over to the Federal Communications Commission by the Communications Act of 1934, it ultimately proved impractical, and was repealed on June 5, 1936. Adoption Radio regulation in the United States had to be suspended in the summer of 1926, when it was ruled that the Commerce Department, operating under the provisions of the Radio Act of 1912, did not have the authority to specify the operating frequencies and powers for broadcasting stations. A period of worsening interference followed, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Order 40
The Federal Radio Commission's (FRC) General Order 40, dated August 30, 1928, described the standards for a sweeping reorganization of radio broadcasting in the United States. This order grouped the AM radio band transmitting frequencies into three main categories, which became known as Clear Channel, Regional, and Local. It also included provisions for coordination with Canadian station assignments. The majority of the reassignments resulting from the plan's implementation went into effect on November 11, 1928. Background Radio transmissions in the United States were originally regulated by the Department of Commerce, as authorized by the Radio Act of 1912. The first formal regulations governing broadcasts intended for the general public were adopted effective December 1, 1921. This initially established just two transmitting wavelengths — 360 meters (833 kHz) for "entertainment" broadcasts, and 485 meters (619 kHz) for "market news and weather reports". The number of ...

North American Regional Broadcasting Agreement
The North American Regional Broadcasting Agreement (NARBA, es, Convenio Regional Norteamericano de Radiodifusión) refers to a series of international treaties that defined technical standards for AM band (mediumwave) radio stations. These agreements also addressed how frequency assignments were distributed among the signatories, with a special emphasis on high-powered clear channel allocations. The initial NARBA bandplan, also known as the "Havana Treaty", was signed by the United States, Canada, Mexico, Cuba, the Dominican Republic, and Haiti on December 13, 1937, and took effect March 29, 1941. A series of modifications and adjustments followed, also under the NARBA name. NARBA's provisions were largely supplanted in 1983, with the adoption of the Regional Agreement for the Medium Frequency Broadcasting Service in Region 2 (Rio Agreement), which covered the entire Western hemisphere. However, current AM band assignments in North America largely reflect the standards first est ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
