XEDKR-AM
XEDKR-AM (700 AM, "Universal") is a Spanish-language radio station in Guadalajara. It relays programming from XHRED-FM 88.1 in Mexico City. 700 kHz is a United States clear-channel frequency. History The first concession for 700 AM in Zapopan was awarded on October 17, 1953, for XEAR-AM and awarded to J. de Jesús Franco Gómez. By the 1960s, the station was transferred to Asociación Radiofónica, S.A., and sometime between 1969 and 1974, the callsign was changed to the present XEDKR-AM as a result of its acquisition by Radio Grupo DK (the Guadalajara arm of Radio Programas de México). It was known as Radio Ambiente in the early 1970s and by the late 1980s had become a direct repeater of Radio Red. It was transferred in 1991 to XEDKR-AM, S.A. de C.V., and sold along with the rest of RPM to Grupo Radio Centro Grupo Radio Centro is a Mexico City-based owner and operator of radio stations.

XESTN-AM
XESTN-AM ( 1540 AM, "Universal") is a Spanish-language radio station in Monterrey, Nuevo León, Mexico. It relays programming from XHRED-FM 88.1 in Mexico City. 1540 AM is a United States clear-channel frequency. History The first concession for XESTN was awarded on November 29, 1988, to Jesús D. González González of Grupo Multimedios. The station was originally daytime-only and licensed to Santa Catarina. It was transferred in 2000 to Radio Red, S.A. de C.V., though Radio Red programs had been airing on XESTN since at least 1994. In 2009, the station increased its daytime power to 5,000 watts. On January 14, 2019, concurrent with a major reshuffling and the relaunch of XERC-FM Mexico City as talk station "Radio Centro 97.7", XESTN and XEDKR-AM Guadalajara began simulcasting that station instead of Radio Red. As part of the launch of Radio Centro's TV station, XHFAMX-TDT, on October 31, 2019, Universal moved to XERC-FM and all the talk programming moved back to XHR ...

Grupo Radio Centro
Grupo Radio Centro is a Mexico City-based owner and operator of radio stations. It owns 30 radio stations in Mexico and the United States, including 8 radio stations in Mexico City. History Radio Centro's origins date to 1946, when Francisco Aguirre Jiménez formed the Cadena Radio Continental to operate XEQR-AM 1030 and new station XERC-AM 790 in Mexico City. Organización Radio Centro was formed in 1952, and the current company was founded in 1971. In 1965, it founded OIR (Organización Impulsora de la Radio), which syndicates Radio Centro's formats to stations across Mexico. Its non-Mexico City business extended further in the 1980s, when Radio Centro began selling its formats outside the United States (in 1983) and created Cadena Radio Centro (in 1986) to manage this portion of its operations. Meanwhile, in Mexico City, it had expanded to five AM stations and three new FM outlets. Radio Centro was the second media company to place its FM towers on Cerro del Chiquihuite, to ...

Radio Programas De México
Radio Programas de México (RPM) was a radio company of Mexico, founded by Emilio Azcárraga Vidaurreta and Clemente Serna Martínez in 1941. It was a pioneer in the expansion of Mexican radio, particularly in the creation of radio networks. RPM, known in its final years as Radiodifusión Red, was sold to Grupo Radio Centro in 1994. History RPM began operations on May 31, 1941, a joint venture of Monterrey broadcaster Clemente Serna Martínez, and Azcárraga, who already owned two of Mexico's most popular radio stations: XEW and XEQ. It was the first company to specialize in selling radio programs recorded on vinyl and magnetic tape.Fernando Mejía BarqueraHistoria mínima de la radio en México/ref> The business model of RPM was incredibly lucrative; it sold the best XEW and XEQ radio programs to stations throughout interior Mexico, offering these small stations programs they could not produce themselves as well as access to national advertising accounts and the ability to char ...

Kilohertz
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 frequ ...

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 (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming se ...

Radio Station
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).

Clear-channel
A clear-channel station is an AM radio station in North America that has the highest protection from 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 stations in the United States, Canada and The Baham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
