City Of License
In American, Canadian, and Mexican broadcasting, a city of license or community of license is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator. In North American broadcast law, the concept of ''community of license'' dates to the early days of AM radio broadcasting. The requirement that a broadcasting station operate a ''main studio'' within a prescribed distance of the community which the station is licensed to serve appears in U.S. law as early as 1939. Various specific obligations have been applied to broadcasters by governments to fulfill public policy objectives of broadcast localism, both in radio and later also in television, based on the legislative presumption that a broadcaster fills a similar role to that held by community newspaper publishers. United States In the United States, the Communications Act of 1934 requires that "the Commission shall make such distribution of licenses, ...

North American Call Sign
Call signs are frequently still used by North American broadcasting, broadcast stations, in addition to amateur radio and other international radio stations that continue to identify by call signs around the world. Each country has a different set of patterns for its own call signs. Call signs are allocated to amateur radio, ham radio stations in Barbados, Canada, Mexico and across the United States. Many countries have specific conventions for classifying call signs by transmitter characteristics and location. The call sign format for radio call sign, radio and television call signs follows a number of conventions. All call signs begin with a prefix assigned by the International Telecommunication Union. For example, the United States has been assigned the following prefixes: AAA–ALZ, K, N, W. For a complete list, see ITU prefix, international call sign allocations. Bermuda, Bahamas, and the Caribbean Pertaining to their status as former or current colonies, all of the British W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anniston, Alabama
Anniston is the county seat of Calhoun County in Alabama and is one of two urban centers/principal cities of and included in the Anniston-Oxford Metropolitan Statistical Area.

Grady for its careful planning in the late 19th century, the city is situated on the slope of Blue Mountain. History Civil War Though the surrounding area was settled much earlier, the mineral resources in the area of Anniston were not exploited until the Civil War. The Confederate States of America then operated an iron furnace near present-day downtown Anniston, until it was finally destroyed by raiding Union cavalry in early 1865. Later, cast iron for sewer systems became the focus of Anniston's industrial output. Cast iron pipe, also called soil pipe, was popular until the advent of plastic pipe in the 1960 ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications ...

Community Radio
Community radio is a radio service offering a third model of radio broadcasting in addition to commercial and public broadcasting. Community stations serve geographic communities and communities of interest. They broadcast content that is popular and relevant to a local, specific audience but is often overlooked by commercial (or) mass-media broadcasters. Community radio stations are operated, owned, and influenced by the communities they serve. They are generally nonprofit and provide a mechanism for enabling individuals, groups, and communities to tell their own stories, to share experiences and, in a media-rich world, to become creators and contributors of media. In many parts of the world, community radio acts as a vehicle for the community and voluntary sector, civil society, agencies, NGOs and citizens to work in partnership to further community development aims, in addition to broadcasting. There is legally defined community radio (as a distinct broadcasting sector) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Translator
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater (two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. It expands the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. However, depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Broadcast translators In its simplest for ...

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 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 onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Service (radio Format)
{{Unreferenced, date=October 2008 Full service (also known as hometown radio) is a type of radio format; the format is characterized by a mix of music programming (usually drawing from formats such as adult contemporary, country, or oldies) and a large amount of locally-produced and hyperlocal programming, such as news and discussion focusing on local issues, sports coverage, and other forms of paid religious and brokered content. It is found mainly on small-market AM radio stations in the United States and Canada, particularly on locally-owned stations in rural areas, although it was once the norm even in larger cities prior to about the 1970s and could be found in some large markets as late as the 1980s. The format differs from community radio in that full-service radio is almost always a commercial enterprise and is not as often ideologically-driven (especially liberal) as some of the more prominent community radio operators are. Nonprofit community radio stations often run for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Automation
Broadcast automation incorporates the use of broadcast programming technology to automate broadcasting operations. Used either at a broadcast network, radio station or a television station, it can run a facility in the absence of a human operator. They can also run in a ''live assist'' mode when there are on-air personnel present at the master control, television studio or control room. The radio transmitter end of the airchain is handled by a separate automatic transmission system (ATS). History Originally, in the US, many (if not most) broadcast licensing authorities required a licensed board operator to run every station at all times, meaning that every DJ had to pass an exam to obtain a license to be on-air, if their duties also required them to ensure proper operation of the transmitter. This was often the case on overnight and weekend shifts when there was no broadcast engineer present, and all of the time for small stations with only a contract engineer on ...

Centralcasting
In terrestrial radio and television broadcasting, centralcasting refers to the use of systems automation by which customised signals for broadcast by multiple individual stations may be created at one central facility. Definition Centralcasting is a form of broadcast automation which operates on the presumption that large quantities of content are similar and are handled in a consistent or repetitive manner across multiple stations in a broadcast station group. While each individual station has its own digital on-screen graphic logo, call sign and identity, much of the content on a typical affiliate station consists of a common television network or syndicated programming with a small number of local broadcast programming time blocks employed for television news and sports television coverage, public affairs programming or local television commercials. Traditionally, many operations at an individual broadcast station were handled manually by broadcast engineering technici ...
