XEROK-AM
XEROK-AM (800 kHz) is a commercial radio station in Ciudad Juárez, Chihuahua, Mexico. It is licensed to operate with a power of 150,000 watts on a carrier frequency of 800 kHz, although its new transmitter outputs 50,000 watts. XEROK is the dominant Class A station on 800 AM, a Mexican clear channel frequency. The station had a colorful history as a border blaster, aiming its programming at listeners in the United States, when at night, its 150,000-watt signal could be easily heard in many parts of the Southwest. XEROK has been silent since April 4, 2022, due to the dismantling of its transmitter facility. History The licensing history for XEROK begins not in Ciudad Juárez but in Piedras Negras, Coahuila, away, with the authorization for XEPNA (more commonly XEPN) 660, made to the Compañia Radiodifusora de Piedras Negras (Piedras Negras Broadcasting Company). The callsign changed to XELO in 1936, authorized for 50 kW day from Piedras Negras but on 1110 k ... [...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 (broadcasting), 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 band, 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, "Peripheral radio, radio périphérique" around France and the U.S. government-funded station Radio Free Europe, targeting European countries behind the Iron Curtain. 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 counterpar ...

List Of 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] |
North American Regional Broadcasting Agreement
The North American Regional Broadcasting Agreement (NARBA, ; ) 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 station, 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 established by the NARBA agreement ...

Audio Transformer
Various types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts. Power transformer Laminated core This is the most common type of transformer, widely used in electric power transmission and appliances to convert mains voltage to low voltage to power electronic devices. They are available in power ratings ranging from mW to MW. The insulated laminations minimize eddy current losses in the iron core. Small appliance and electronic transformers may use a split bobbin, giving a high level of insulation between the windings. The rectangular cores are made up of stampings, often in E-I shape pairs, but other shapes are sometimes used. Shields between primary and secondary may be fitted to reduce EMI (electromagnetic interference), or a screen winding is occasionally used. Small appliance and electronics t ...

Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force, electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change Alternating current, AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voice-tracking
Voice-tracking, also called cyber jocking and referred to sometimes colloquially as a robojock, is a technique employed by some radio stations in radio broadcasting to produce the illusion of a live disc jockey or announcer sitting in the radio studios of the station when one is not actually present. It is one of the notable effects of radio homogenization. Background Voice-tracking refers to the process of a disc jockey prerecording their on-air "patter". It is then combined with songs, commercials, and other elements in order to produce a product sounding like a live air shift. Voice-tracking has become common on many music radio stations, particularly during evening, overnight, weekend, and holiday time periods. Most radio station owners consider it an economical alternative to employing live disc jockeys around the clock. The process goes back decades and was very common on FM stations in the 1970s. At that time, elements were recorded on reel-to-reel magnetic tapes and bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
