Local Marketing Agreement
In North American broadcasting, a local marketing agreement (LMA), or local management agreement, is a contract in which one corporation, company agrees to operate a radio station, radio or television station owned by another party. In essence, it is a sort of lease or time-buy. Under Federal Communications Commission (FCC) regulations, a local marketing agreement must give the company operating the station (the "senior" partner) under the agreement control over the entire facilities of the station, including the finances, personnel and programming of the station. Its original licensee (the "junior" partner) still remains legally responsible for the station and its operations, such as compliance with relevant regulations regarding content. Occasionally, a "local marketing agreement" may refer to the sharing or contracting of only certain functions, in particular advertising sales. This may also be referred to as a time brokerage agreement (TBA), local sales agreement (LSA), manage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flagship (broadcasting)
In broadcasting, a flagship (also known as a flagship station or key station) is the broadcast station which originates a television network, or a particular radio or television program that plays a key role in the branding of and consumer loyalty to a network or station. This includes both direct network feeds and broadcast syndication, but generally not backhauls. Not all networks or shows have a flagship station, as some originate from a dedicated radio or television studio. The term derives from the naval custom where the commanding officer of a group of naval ships would fly a distinguishing flag. In common parlance, "flagship" is now used to mean the most important or leading member of a group, hence its various uses in broadcasting. The term ''flagship station'' is primarily used in TV and radio in the United States, Canada, and the Philippines (though it is seldomly used), while the term is primarily used in TV in Japan (and formerly in the United States).

Little Calumet River
The Calumet River is a system of industrialized rivers and canals in the region between the South Side, Chicago, south side of Chicago, Illinois, and the city of Gary, Indiana. Historically, the Little Calumet River and the Grand Calumet River were one, the former flowing west from Indiana into Illinois, then turning back east to its mouth at Lake Michigan at Marquette Park (Gary), Marquette Park in Gary. Now the system is part of the Chicago Area Waterway System and through the use of locks flows away from Lake Michigan to the Cal-Sag Channel. Background The name "Calumet" is from the French colonial name for a particular type of Indigenous peoples in the United States, Native American ceremonial pipe that served as a universal sign of peace among the Illiniwek, and which was presented to Jacques Marquette, Pere Marquette in 1673. Before human alteration, water flowed westward from LaPorte County, Indiana, along the Little Calumet River, made a hairpin turn at Blue Island, Il ...

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] |
San Antonio
San Antonio ( ; Spanish for " Saint Anthony") is a city in the U.S. state of Texas and the most populous city in Greater San Antonio. San Antonio is the third-largest metropolitan area in Texas and the 24th-largest metropolitan area in the United States at 2.6 million people in the 2020 United States census. It is the most populous city in and the county seat of Bexar County. San Antonio is the seventh-most populous city in the United States, and the second-most populous in the Southern United States and Texas, after Houston. Founded as a Spanish mission and colonial outpost in 1718, the city in 1731 became the first chartered civil settlement in what is now present-day Texas. The area was then part of the Spanish Empire. From 1821 to 1836, it was part of the Mexican Republic. It is the oldest municipality in Texas, having celebrated its 300th anniversary on May 1, 2018.

List Of North American Broadcast Station Classes
This is a list of broadcast station classes applicable in much of North America under international agreements between the United States, Canada and Mexico. Effective radiated power (ERP) and height above average terrain (HAAT) are listed unless otherwise noted. All radio and television stations within of the US-Canada or US-Mexico border must get approval by both the domestic and foreign agency. These agencies are Industry Canada/ Canadian Radio-television and Telecommunications Commission (CRTC) in Canada, the Federal Communications Commission (FCC) in the US, and the Federal Telecommunications Institute (IFT) in Mexico. AM Station class descriptions All domestic (United States) AM stations are classified as A, B, C, or D. * A (formerly I) — clear-channel stations — 10 kW to 50 kW, 24 hours. **Class A stations are only protected within a radius of the transmitter site. **The old Class I was divided into three: Class I-A, I-B and I-N.

Clear Channel Station
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] |
