XETRA-AM
XEWW-AM (690 kHz) is a radio station licensed to the Rosarito/Tijuana area of Baja California, Mexico. XEWW airs a Spanish language talk format. Transmitter XEWW is a high-powered Class A station, with its 77,000-watt daytime signal sometimes reaching as far as the middle of the San Joaquin Valley. It covers nearly all of Southern California and most of Baja California. XEWW operates with 50,000 watts at night as is required by the "Rio Treaty". This same treaty would normally allow XEWW to operate with a daytime signal of 100,000 watts. However, 77,000 watts was apparently selected as this power sends the equivalent of the station's former 50,000-watt daytime signal (from its original Tijuana site, since demolished) towards Los Angeles without also increasing its prohibited overlap with KIRN (670 AM) in Simi Valley and KSPN (710 AM) in Los Angeles (from its present Rosarito site). At night it uses a five-tower array directional antenna, decreasing power to 50,000 watts t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Playas De Rosarito
is a coastal city in Playas de Rosarito Municipality, Baja California, on the Pacific Coast of Mexico. As of 2010, the city had a population of 65,278. Located south of the US–Mexico border, Rosarito is a part of the greater San Diego–Tijuana region and one of the westernmost cities in Mexico. Rosarito is a major tourist destination, known for its beaches, resorts, and events like Baja Beach Fest. History Evidence of the presence of Paleo-Indians in the region has been dated as early as 2,000 BC. By 1,000 BC, a group emerged that is recognizable as the Yuman ancestors of the Kumeyaay, who continued to inhabit the northern portion of the Baja California Peninsula at the time of European contact. The Kumeyaay referred to the area now known as Rosarito as ''Wa-cuatay'', which translates to "big houses" in the Kumeyaay language. Spanish era After conquering the Aztec Empire, Hernán Cortés sent expeditions to explore what he believed to be the Island of California. In 1533 ...

Regional Agreement For The Medium Frequency Broadcasting Service In Region 2
The Regional Agreement for the Medium Frequency Broadcasting Service in Region 2, commonly known as the Rio Agreement, is an international treaty defining standards for AM band (mediumwave) radio stations.

XETV-TDT
XETV-TDT (channels 6 and 16) is a television station located in Tijuana, Baja California, Mexico, broadcasting programs from Canal 5 and NU9VE. Its terrestrial signal also covers the San Diego area across the Mexico–United States border. The station is owned by Grupo Televisa, and its technical operations and transmitter facilities are located at Mount San Antonio in Tijuana. From its initial sign-on in 1953 until 2017, XETV broadcast English-language programming and operated business offices, and later a studio and newsroom, in San Diego. The station's American operations were managed by Bay City Television, a California-based corporation owned by Televisa. It was most recently an affiliate of The CW. XETV ceased its San Diego operations on May 31, 2017; The CW moved its San Diego affiliation from XETV's main channel to a subchannel of KFMB-TV (channel 8.2) the following day; XETV's cable channel 6 was transitioned to KFMB-DT2 on the same date.

NARBA
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 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 agreements. Background Orga ...

Jorge I
Jorge is the Spanish and Portuguese form of the given name George. While spelled alike, this name is pronounced very differently in each of the two languages: Spanish ; Portuguese . It is derived from the Greek name Γεώργιος (''Georgios'') via Latin ''Georgius''; the former is derived from (''georgos''), meaning "farmer" or "earth-worker". The Latin form ''Georgius'' had been rarely given in Western Christendom since at least the 6th century. The popularity of the name however develops from around the 12th century, in Occitan in the form '' Jordi'', and it becomes popular at European courts after the publication of the '' Golden Legend'' in the 1260s. The West Iberian form ''Jorge'' is on record in Portugal as the name of Jorge de Lencastre, Duke of Coimbra (1481–1550). List of people with the given name Jorge * Jorge (footballer, born 1939), Brazilian footballer * Jorge (footballer, born 1946), Brazilian footballer * Jorge (Brazilian singer), Brazilian musici ...

Agua Caliente, Tijuana
Agua Caliente is a historic entertainment center and present-day district of Tijuana, Baja California, Mexico, at the southeastern end of the ''Centro'' borough. The ''Agua Caliente Tourist Complex'' formed in the late 1920s along Agua Caliente Boulevard when a road was built that led from the historic Rio Zone to a natural hot springs two miles up the Tijuana River Valley. Paramount icons of Tijuana developed in Agua Caliente such as the Agua Caliente Casino and Hotel and the Agua Caliente Racetrack.

Directional Antenna
A directional antenna or beam antenna is an antenna that radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only. This can increase the power transmitted to receivers in that direction, or reduce interference from unwanted sources. This contrasts with omnidirectional antennas such as dipole antennas which radiate radio waves over a wide angle, or receive from a wide angle. The extent to which an antenna's angular distribution of radiated power, its radiation pattern, is concentrated in one direction is measured by a parameter called antenna gain. A high-gain antenna (HGA) is a directional antenna with a focused, narrow beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tower Array
A tower array is an arrangement of multiple radio towers which are mast radiators in a phased array. They were originally developed as ground-based tracking radars. Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a directional antenna of a mediumwave or longwave radio station. The number of towers in a tower array can vary. In many arrays all towers have the same height, but there are also arrays of towers of different height. The arrangement can vary. For directional antennas with fixed radiation pattern, linear arrangements are preferred, while for switchable directional patterns (usually for daytime groundwave versus nighttime skywave), square arrangements are chosen. Examples Tower arrays with guyed masts * Longwave transmitter Europe 1 * Transmitter Weisskirchen * Beidweiler Longwave Transmitter * Transmitter Wachenbrunn * Transmitter Ismaning (VoA-Station) Tower arrays with free-standing towers * Junglins ...
