XHIMR-FM
XHIMR-FM is a radio station in Mexico City. Broadcasting on 107.9 FM from a tower in Ajusco, XHIMR is owned by the Instituto Mexicano de la Radio and broadcasts a jazz music format under the brand name Horizonte 107.9. History XHIMR-FM received its permit late in 1999; with a three-month deadline to come on air, it signed on February 15, 2000 as "Horizonte 108" utilizing content from other IMER stations, particularly XHOF-FM. The station's original programming included New Age and electronic music, which was eliminated early on, as well as informative programs in the lead-up to the 2000 presidential election. This content was deemphasized as time went on, with the station focusing on jazz and world music in its programming. In 2005, XHIMR boosted its power to 30 kW from its original 10, while dropping the "108" moniker (which had confused listeners). In 2010, it increased its jazz focus. Format Horizonte 107.9 primarily broadcasts jazz music. HD Programming The station broa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Department had a hard time procuring the permit; one month after it was issued, the government was still evaluating the technical parameters. Additionally, the original callsign of XEDO-FM had to be changed (in April 1968) when it was discovered that a Michoacán radio station had been using those calls since 1961. In March 1969, the SCT informed the DDF that the latter still had not complied with the requirements for the construction of the station.

Greater Mexico City
Greater Mexico City refers to the conurbation around Mexico City, officially called Metropolitan Area of the Valley of Mexico ( es, Zona metropolitana del Valle de México). It encompasses Mexico City itself and 60 adjacent municipalities of the State of Mexico and Hidalgo. Mexico City's metropolitan area is the economic, political, and cultural hub of Mexico. In recent years it has reduced its relative importance in domestic manufacturing, but has kept its dominant role in the country’s economy thanks to an expansion of its tertiary activities. The area is also one of the powerhouse regions of Latin America, generating approximately $200 billion in GDP growth or 10 percent of the regional total. , 21,804,515 people lived in Greater Mexico City, making it the largest metropolitan area in North America.

Megahertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or Cycle per second, 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 Hertz, Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in metric prefix, 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 photon energy, energy of a photon, via the Planck relation ''E'' = ''hν'', ...

Ajusco
Ajusco is a lava dome volcano located just south of Mexico City, Mexico, in the Tlalpan borough of the city. It is the highest point in the city. Etymology Ajusco is a Náhuatl word variously translated as "source of waters" or "watered grove", and the Lerma River and Balsas River draw some of their source waters from this area. Also, the flow from all of the remaining strong springs in the area adjacent to the peak are captured to augment Mexico City's water supply. Geology Ajusco is a lava dome complex of Pliocene-Pleistocene age, surrounded by block and ash flow deposits. Ajusco is part of the mountain chain of volcanic origin known as Sierra de Ajusco-Chichinauhtzin, among which Xitle (), Tláloc (), Pelado (), Cuautzin () and Chichinautzin () stand out. This range is part of the Trans-Mexican Volcanic Belt which crosses central Mexico and contains the country's highest peaks. Ecology Parts of this range account for about half of the area of the Mexican Federal District, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD Radio
HD Radio (HDR) is a trademark for an in-band on-channel (IBOC) digital radio broadcast technology. It generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by AM and FM radio stations in the United States, Canada, and Mexico, with a few implementations outside North America. The term "on channel" is a misnomer because the system actually broadcasts on the ordinarily unused channels adjacent to an existing radio station's allocation. This leaves the original analog signal intact, allowing enabled receivers to switch between digital and analog as required. In most FM implementations, from 96 to 128 kbps of capacity is available. High-fidelity audio requires only 48 kbps so there is ample capacity for additional channels, which HD Radio refers to as "multicasting". HD Radio is licensed so that the simulcast of the main channel is royalty-free. The company makes its money ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jazz Radio Stations
Jazz is a music genre that originated in the African-American communities of New Orleans, Louisiana in the late 19th and early 20th centuries, with its roots in blues and ragtime. Since the 1920s Jazz Age, it has been recognized as a major form of musical expression in traditional and popular music. Jazz is characterized by swing and blue notes, complex chords, call and response vocals, polyrhythms and improvisation. Jazz has roots in European harmony and African rhythmic rituals. As jazz spread around the world, it drew on national, regional, and local musical cultures, which gave rise to different styles. New Orleans jazz began in the early 1910s, combining earlier brass band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. But jazz did not begin as a single musical tradition in New Orleans or elsewhere. In the 1930s, arranged dance-oriented swing big bands, Kansas City jazz (a hard-swinging, bluesy, improvisational style ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Stations Established In 2000
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
