City Of License
In U.S., 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, frequenci ...

Kilocycle
The cycle per second is a once-common English name for the unit of frequency now known as the ''hertz'' (Hz). Cycles per second may be denoted by c.p.s., c/s, or, ambiguously, just "cycles" (Cyc., Cy., C, or c). The term comes from repetitive phenomena such as sound waves having a frequency measurable as a number of oscillations, or cycles, per second. With the organization of the International System of Units in 1960, the cycle per second was officially replaced by the hertz, or reciprocal second, "sā1" or "1/s". Symbolically, "cycle per second" units are "cycle/second", while hertz is "Hz" or "sā1". For higher frequencies, ''kilocycles'' (kc), as an abbreviation of ''kilocycles per second'' were often used on components or devices. Other higher units like ''megacycle'' (Mc) and less commonly ''kilomegacycle'' (kMc) were used before 1960 and in some later documents. These have modern equivalents such as kilohertz (kHz), megahertz (MHz), and gigahertz (GHz). Following the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daytimer
A clear-channel station is a North American AM radio station that has the highest level of protection from interference from other stations, particularly from nighttime skywave signals. This classification exists to ensure the viability of cross-country or cross-continent radio service enforced through a series of treaties and statutory laws. Known as Class A stations since the 1983 adoption of the Regional Agreement for the Medium Frequency Broadcasting Service in Region 2 (Rio Agreement), they are occasionally still referred to by their former classifications of Class I-A (the highest classification), Class I-B (the next highest class), or Class I-N (for stations in Alaska too far away to cause interference to the primary clear-channel stations in the lower 48 states). The term "clear-channel" is used most often in the context of North America and the Caribbean, where the concept originated. Since 1941, these stations have been required to maintain a transmitter power output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Radio
Christian radio refers to Christian media radio formats that focus on Christian religious broadcasting or various forms of Christian music. Many such formats and programs include contemporary Christian music, gospel music, sermons, radio dramas, as well as news and talk shows covering popular culture, economics, and political topics from a Christian perspective. History American evangelicalism In the first part of the 20th century, American revivalists saw radio as a tool for spreading the gospel. Christian radio pioneers included Aimee Semple McPherson, D. L. Moody, Charles E. Fuller, Donald Barnhouse, Walter A. Maier, Paul Rader, Lightfoot Solomon Michaux, and Percy Crawford. In addition to preaching and sermons, other content such as news, children's programs, and gospel music were broadcast. Scholar Leah Payne states "In the 1920s, hristianbroadcasters featured gospel quartets and trios who upheld the traditional social order and contrasted with images of ' b ...

Sign-on
A sign-on (or start-up in Commonwealth countries except Canada) is the beginning of operations for a radio or television station, generally at the start of each day. It is the opposite of a sign-off (or closedown in Commonwealth countries except Canada), which is the sequence of operations involved when a radio or television station shuts down its transmitters and goes off the air for a predetermined period; generally, this occurs during the overnight hours although a broadcaster's digital specialty or sub-channels may sign-on and sign-off at significantly different times than its main channels. Like other television programming, sign-on and sign-off sequences can be initiated by a broadcast automation system, and automatic transmission systems can turn the carrier signal and transmitter on/off by remote control. Sign-on and sign-off sequences have become less common due to the increasing prevalence of 24/7 broadcasting. However, some national broadcasters continue the pra ...

Lafayette Hill, Pennsylvania
Lafayette Hill is an unincorporated community, which is situated primarily within Whitemarsh Township, Montgomery County, Pennsylvania. A small part of this community is also located in Springfield Township. Located just west of Philadelphia's Chestnut Hill neighborhood, and south of Plymouth Meeting, Lafayette Hill, which has also been known, historically, as "Barren Hill," draws its name from the French General Marquis de Lafayette, who encamped there with his soldiers during the American Revolution. History Before the general decampment from Valley Forge in the spring of 1778, George Washington dispatched an estimated 2,200 troops under the command of Marquis de Lafayette to act as a defensive screen and to conduct reconnaissance of the British army, which had garrisoned in Philadelphia for the winter. The two forces had a brief engagement at nearby Barren Hill. The community's post office name was officially changed from Barren Hill to Lafayette Hill in March 1883.

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna (radio), antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna Electromagnetic radiation, radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio (audio) and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tower Array
A tower array is an arrangement of multiple radio towers which are mast radiators in a phased array. They were originally developed as ground-based tracking radars. Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a directional antenna of a mediumwave or longwave radio station. The number of towers in a tower array can vary. In many arrays all towers have the same height, but there are also arrays of towers of different height. The arrangement can vary. For directional antennas with fixed radiation pattern, linear arrangements are preferred, while for switchable directional patterns (usually for daytime groundwave versus nighttime skywave), square arrangements are chosen. Examples Tower arrays with guyed masts * Longwave transmitter Europe 1 * Transmitter Weisskirchen * Beidweiler Longwave Transmitter * Transmitter Wachenbrunn * Transmitter Ismaning (VoA-Station) Tower arrays with free-standing towers * Junglins ...

Directional Antenna
A directional antenna or beam antenna is an antenna that radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only. This can increase the power transmitted to receivers in that direction, or reduce interference from unwanted sources. This contrasts with omnidirectional antennas such as dipole antennas which radiate radio waves over a wide angle, or receive from a wide angle. The extent to which an antenna's angular distribution of radiated power, its radiation pattern, is concentrated in one direction is measured by a parameter called antenna gain. A high-gain antenna (HGA) is a directional antenna with a focused, narrow beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
