XHAB-FM
XHAB-FM is a radio station in Santa Ana, Sonora, Mexico. History XEAB-AM 1400 hit the air on December 12, 1947, known as "Las Cuatro Iniciales de Oro de Santa Ana". The 250- watt station was owned by Alfredo Marín Castro and had received its concession the previous August. By the 1980s, XEAB was broadcasting with 500 watts (later reduced to 250 again). In November 1989, XEAB was transferred to 15 members of the Marín family: Guadalupe and Luis Alfredo Marín Méndez; Leticia, Rubén, Griselda, and Jackeline Marín Yescas; Yolanda, Gilberto and Eduardo Marín González; Elisa Marín Martínez de Gutiérrez; Aurora Yescas; Micaela Méndez Alvarez; Eloisa Martínez Arvizu; and Adolfo and Leopoldo Marín Martínez. In 2006, the Marín successors were cleared to sell XEAB to Radio S.A. In 2011, Radio S.A. was approved to migrate XEAB from the AM band to the FM band as XHAB-FM 98.7. However, XEAB has been mired in the same labor problems affecting Radio S.A. in Hermosillo, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Ana, Sonora
Santa Ana is a small city and municipal seat of Santa Ana Municipality in the Mexican state of Sonora. It is located north of the state capital Hermosillo and south of Nogales on the United States border. The town had a 2005 census population of 10,593 inhabitants History This settlement originated when the Pimas (indigenous people in northwest Mexico) settled in the area now called Santa Ana Viejo attracted by the mission established by the Jesuits. The present town of Santa Ana was founded by Diego A. Moreno in the year 1883, when the Sonoran Railroad was being built in this area of the state. Santa Ana achieved the status of a municipality in 1935. The movie The Fast and The Furious was filmed throughout the months of June and July, 2008, in Santa Ana as well as Magdalena de Kino, Sonora.

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). Television broadcasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Secretariat Of Communications And Transportation (Mexico)
The Secretariat of Infrastructure, Communications and Transportation (''Secretaría de Infraestructura, Comunicaciones y Transportes'', SICT) of Mexico is the national federal entity that regulates commercial road traffic and broadcasting. Its headquarters are in the Torre Libertad on Reforma in Mexico City but some aspects of the department still function at the old headquarters located at the intersection of Eje Central and Eje 4 Sur (Xola). The building is decorated with murals created by arranging small colored stones on the building's outer walls. Historical nomenclature The forerunner of the modern-day SCT was created in 1891 under President of Mexico, President Porfirio Díaz and was known as the Secretariat of Communications ''(Secretaría de Comunicaciones)''; its first incumbent as secretary was Manuel González Cosío. In 1920 it was renamed to the Secretariat of Communications and Public Works ''(Secretaría de Comunicaciones y Obras Públicas;'' "SCOP"). In 1959, i ...

Medium Wave
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet. MW was the main radio ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FM Broadcast Band
The FM broadcast band is a range of radio frequencies used for FM broadcasting by radio stations. The range of frequencies used differs between different parts of the world. In Europe and Africa (defined as International Telecommunication Union (ITU) region 1) and in Australia and New Zealand, it spans from 87.5 to 108 megahertz (MHz) - also known as VHF Band II - while in the Americas (ITU region 2) it ranges from 88 to 108 MHz. The FM broadcast band in Japan uses 76 to 95 MHz, and in Brazil, 76 to 108 MHz. The International Radio and Television Organisation (OIRT) band in Eastern Europe is from 65.9 to 74.0 MHz, although these countries now primarily use the 87.5 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 87.5 to 108 MHz band. Frequency modulation radio originated in the United States during the 1930s; the system was developed by the American electrical engineer ...

Amplitude Modulation
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in which either the frequency of the carrier wave is varied, as in frequency modulation, or its phase, as in phase modulation. AM was the earliest modulation method used for transmitting audio in radio broadcasting. It was developed during the first quarter of the 20th century beginning with Roberto Landell de Moura and Reginald Fessenden's radiotelephone experiments in 1900. This original form of AM is sometimes called double-sideband amplitude modulation (DSBAM), because the standard method produces sidebands on either side of the carrier frequency. Single-sideband modulation uses bandpass filters to eliminate one of the sidebands and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency Modulation
Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and Run-length limited#FM: .280.2C1.29 RLL, computing. In Analog signal, analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the instantaneous frequency deviation, i.e. the difference between the frequency of the carrier and its center frequency, has a functional relation to the modulating signal amplitude. Digital data can be encoded and transmitted with a type of frequency modulation known as frequency-shift keying (FSK), in which the instantaneous frequency of the carrier is shifted among a set of frequencies. The frequencies may represent digits, such as '0' and '1'. FSK is widely used in computer modems, such as fax modems, telephone caller ID systems, garage door openers, and other low-frequency transmissions. R ...

Radio Stations In Sonora
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] |
