Underground Radio
Pirate radio or a pirate radio station is a radio station that broadcasts without a valid license. In some cases, radio stations are considered legal where the signal is transmitted, but illegal where the signals are received—especially when the signals cross a national boundary. In other cases, a broadcast may be considered "pirate" due to the nature of its content, its transmission format (especially a failure to transmit a station identification according to regulations), or the transmit power (wattage) of the station, even if the transmission is not technically illegal (such as an amateur radio transmission). Pirate radio is sometimes called bootleg radio (a term especially associated with two-way radio), clandestine radio (associated with heavily politically motivated operations) or free radio. History Radio "piracy" began with the advent of regulations of the airwaves at the dawn of the age of radio. Initially, radio, or wireless as it was more commonly called at ...

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] |
Border Blaster
A border blaster is a broadcast station that, though not licensed as an external service, is, in practice, used to target another country. The term "border blaster" is of North American origin, and usually associated with Mexican AM stations whose broadcast areas cover large parts of the United States, and United States border AM stations covering large parts of Canada. Conceptually similar European broadcasting included some pre-World War II broadcasting towards the United Kingdom, " radio périphérique" around France and the U.S. government-funded station Radio Free Europe, targeting eastern Europe. With broadcasting signals far more powerful than those of U.S. stations, the Mexican border blasters could be heard over large areas of the U.S. from the 1940s to the 1970s, often to the great irritation of American radio stations, whose signals could be overpowered by their Mexican counterparts. These are also sometimes referred to as X stations for their call letters: Mexico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Radio Act Of 1927
The Radio Act of 1927 (United States Public Law 632, 69th Congress) was signed into law on February 23, 1927. It replaced the Radio Act of 1912, increasing the federal government's regulatory powers over radio communication, with oversight vested in a newly created body, the Federal Radio Commission. It also was the first legislation to mandate that stations had to show they were "in the public interest, convenience, or necessity" in order to receive a license. The Act was later replaced by the Communications Act of 1934. Previous regulation 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, which placed licensing authority under the Department of Commerce. However, a pair of successful legal cases challenging the federal government's powers under the 1912 Act led to its eventual replacement. In 1921 the Commerce Department had tried ...

WJAZ (Chicago)
WJAZ was the call sign used from 1922 to 1931 by a series of four separate, but closely related, broadcasting stations located in Chicago, Illinois and operated by the Chicago Radio Laboratory/Zenith Radio Corporations. The original WJAZ was first licensed in the summer of 1922, and the next year began broadcasting from the Edgewater Beach Hotel in Chicago. However, it was soon determined that a suburban transmitter location would be preferable, and Zenith began preparations to re-establish WJAZ's operations at a more suitable site. Following operation for a few weeks by the ''Chicago Tribune'' as WGN, the station license for the original WJAZ was sold to the hotel management, and the call letters changed to WEBH. In order to maintain control of the well-known WJAZ call sign until the new facility was ready, in 1924 Zenith briefly renamed a second Chicago station, WSAX, to WJAZ. Later that year, Zenith prepared a portable broadcasting station, mounted on a truck body, in order to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Station WJAZ, Chicago, 'wave Pirates' Publicity Photograph (1926)
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbert Hoover
Herbert Clark Hoover (August 10, 1874 – October 20, 1964) was an American politician who served as the 31st president of the United States from 1929 to 1933 and a member of the Republican Party, holding office during the onset of the Great Depression in the United States. A self-made man who became rich as a mining engineer, Hoover led the Commission for Relief in Belgium, served as the director of the U.S. Food Administration, and served as the U.S. Secretary of Commerce. Hoover was born to a Quaker family in West Branch, Iowa, but he grew up in Oregon. He was one of the first graduates of the new Stanford University in 1895. He took a position with a London-based mining company working in Australia and China. He rapidly became a wealthy mining engineer. In 1914 at the outbreak of World War I, he organized and headed the Commission for Relief in Belgium, an international relief organization that provided food to occupied Belgium. When the U.S. entered the war in 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secretary Of Commerce
The United States secretary of commerce (SecCom) is the head of the United States Department of Commerce. The secretary serves as the principal advisor to the president of the United States on all matters relating to commerce. The secretary reports directly to the president and is a statutory member of Cabinet of the United States. The secretary is appointed by the president, with the advice and consent of the United States Senate. The secretary of commerce is concerned with promoting American businesses and industries; the department states its mission to be "to foster, promote, and develop the foreign and domestic commerce". Until 1913, there was one secretary of commerce and labor, uniting this department with the United States Department of Labor, which is now headed by a separate United States secretary of labor. Secretary of Commerce is a Level I position in the Executive Schedule, thus earning a salary of US$221,400, as of January 2021. The current secretary of commer ...

Air Time (broadcasting)
Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as early as 1898. Over the air broadcasting is usually associated with radio and television, though more r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Telephone And Telegraph Company
AT&T Inc. is an American multinational telecommunications holding company headquartered at Whitacre Tower in Downtown Dallas, Texas. It is the world's largest telecommunications company by revenue and the third largest provider of mobile telephone services in the U.S. , AT&T was ranked 13th on the ''Fortune'' 500 rankings of the largest United States corporations, with revenues of $168.8 billion. During most of the 20th century, AT&T had a monopoly on phone service in the United States. The company began its history as the American District Telegraph Company, formed in St. Louis in 1878. After expanding services to Arkansas, Kansas, Oklahoma and Texas, through a series of mergers, it became Southwestern Bell Telephone Company in 1920, which was then a subsidiary of American Telephone and Telegraph Company. The latter was a successor of the original Bell Telephone Company founded by Alexander Graham Bell in 1877. The American Bell Telephone Company formed the American Tele ...
