XHRUV-FM
XHRUV-FM is the radio station of the Universidad Veracruzana in the state of Veracruz, Mexico. It broadcasts from the state capital of Xalapa on 90.5 MHz. It uses the identification "Radio UV" and broadcasts a mix of news, cultural shows and classical music from its transmitter in Acajete, Veracruz. The station is on the air from 5 a.m. to 1 a.m. XHRUV is the successor to XERUV-AM, which was a Class A clear-channel station on 1550 AM in Xalapa that is now silent. History Radio UV was established on 15 September 1944, just days after the university itself, and was broadcasting with 200 watts on 580 kHz as XEJJ by 1946. By 1955, it increased power to 500 watts and moved to 1400 kHz,Though the university website says that the move to 1400 was in 1955 and the callsign change to XEXB was in 1958, the station was already listed as XEXB with 500 watts daytime and 250 watts nighttime on 1400kHz in the 1953 version of and began transmitting from the Cerro de Macuiltà ...

AM Broadcasting
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have also greatly shrunk due to competition from FM (FM broadcasting, frequency modulation) radio, Digital audio broadcasting, Digital Audio Broadcasting (DAB), satellite radio, HD Radio, HD (digi ...

University Radio Stations In Mexico
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens ...

Radio Stations Established In 1944
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] |
Federal Telecommunications Institute
The Federal Telecommunications Institute ( Spanish: ''Instituto Federal de Telecomunicaciones''; abbreviated as IFT and incorrectly referred to as IFETEL) is an independent government agency of Mexico charged with the regulation of telecommunications and broadcasting services. It was formed on September 10, 2013, as part of larger reforms to Mexican telecom regulations, and replaced the Federal Telecommunications Commission (Cofetel). The current President of the IFT is Gabriel Oswaldo Contreras SaldÃvar. History On August 8, 1996, President Ernesto Zedillo created Cofetel, which originally was based in the tower of the Secretariat of Communications and Transportation. In 2013, President Enrique Peña Nieto created the IFT to replace Cofetel as part of the telecommunications reform package of the Pacto por México. The IFT is an autonomous federal agency that is responsible for the regulation of the use of spectrum, telecommunications and broadcasting networks and offerings, a ...

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 as 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-hour-a-day, seven-day-a-week broadcasting. However, some national broadc ...

Sister Station
In broadcasting, sister stations or sister channels are radio or television stations operated by the same company, either by direct ownership or through a management agreement. Radio sister stations will often have different formats, and sometimes one station is on the AM band while another is on the FM band. Conversely, several types of sister-station relationships exist in television; stations in the same city will usually be affiliated with different television networks (often one with a major network and the other with a secondary network), and may occasionally shift television programs between each other when local events require one station to interrupt its network feed. Sister stations in separate (but often nearby) cities owned by the same company may or may not share a network affiliation. For example, WNYW and WWOR-TV, in New York City and Secaucus, New Jersey, are both owned by Fox Corporation. WNYW is a Fox owned-and-operated station; WWOR-TV is a MyNetworkTV own ...

Foreign Broadcast Information Service
The Foreign Broadcast Information Service (FBIS) was an open source intelligence component of the Central Intelligence Agency's Directorate of Science and Technology. It monitored, translated, and disseminated within the U.S. government openly available news and information from media sources outside the United States. Its headquarters was in Rosslyn, later Reston, Virginia, and it maintained approximately 20 monitoring stations worldwide. In November 2005, it was announced that FBIS would become the newly formed Open Source Center, tasked with the collection and analysis of publicly available intelligence. History On 26 February 1941, President Roosevelt directed that $150,000 be allocated for creation of the Foreign Broadcast Monitoring Service (FBMS) under the authority of the Federal Communications Commission. The mandate of the FBMS was to record, translate, transcribe and analyze shortwave propaganda radio programs that were being beamed at the United States by the Axis ...

Dark (broadcasting)
In the broadcasting industry, a dark television station or silent radio station is one that has gone off the air for an indefinite period of time. Usually unlike dead air (broadcasting only silence), a station that is dark or silent does not even transmit a carrier signal. U.S. law Transmitter operations According to the U.S. Federal Communications Commission (FCC), a radio or television station is considered to have gone dark or silent if it is to be off the air for thirty days or longer. Prior to the Telecommunications Act of 1996, a "dark" station was required to surrender its broadcast license to the FCC, leaving it vulnerable to another party applying for it while its current owner was making efforts to get it back on the air. Following the 1996 landmark legislation, a licensee is no longer required to surrender the license while dark. Instead, the licensee may apply for a "Notification of Suspension of Operations/Request for Silent STA" (FCC Form 0386), stating the reas ...

Clear-channel Station
A clear-channel station is an AM broadcasting, AM radio station in North America that has the highest protection from Interference (communication), interference from other stations, particularly concerning night-time skywave propagation. The system 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 1982, 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 an effective radiated power of at least 10,000 watts to retain their status. Nearly all such station ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...
