Tijuana
–
Tijuana is the largest city in Baja California and on the Baja California Peninsula and center of the Tijuana metropolitan area, part of the international San Diego–Tijuana metropolitan area. As an industrial and financial center of Mexico, Tijuana exerts an influence on economics, education, culture, art. As the city has become a center in the country, so has the surrounding metropolitan area. Currently one of the fastest growing areas in Mexico, Tijuana maintains global city status. As of 2015, the city of Tijuana had a population of 1,696,923, Tijuana is located on the Gold Coast of Baja California, and is the municipal seat and cultural and commercial center of Tijuana Municipality. Tijuana covers 70% of the municipality but contains over 80% of its population, a dominant manufacturing center of the North American continent, the city maintains facilities of many multinational conglomerate companies. In the early 21st century, Tijuana became the medical-device manufacturing capital of North America, Tijuana is also a growing cultural center and has been recognized as an important new cultural mecca. The city is the most visited city in the globe. More than fifty million people cross the border between two cities every year. This metropolitan crossing makes the San Ysidro Port of Entry the busiest land-border crossing in the world and it is estimated that the two border crossing stations between the cities proper of San Diego and Tijuana account for 300,000 daily border crossings alone. Tijuana is the 40th largest city in the Americas and is the westernmost city in Mexico, Tijuana traces its modern history to the arrival of Spanish explorers in the 16th century who were mapping the coast of the Californias. As the American conquest of northern Mexico ended with the Treaty of Guadalupe Hidalgo, Tijuanas new international position on the border gave rise to a new economic, the city was founded in July 11,1889 as urban development began. Often known by its initials, T. J. and nicknamed Gateway to Mexico, Tijuana derives from the Kumeyaay word Tiwan, meaning by-the-sea. Common in regional folklore, a myth exists purporting that the name is a conjunction of Tia Juana, Tia Juana would provide food and a resting place to travelers on their journeys. The story has become a myth with residents of the city and has particular resonance among those who like to imagine the city as a place of hospitality. In Spanish, the name is pronounced /tiˈxwana/ – with three syllables, and a fricative as represented by the sound written as j. In California, and particularly in Southern California, it is referred to as T. J. Baja Californians have adopted this pronunciation as Tiyei, in Spanish the demonym for someone from Tijuana is Tijuanense, while in English the demonym is Tijuanan

Baja California
–
Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northernmost and westernmost of the 32 Federal Entities of Mexico, before becoming a state in 1952, the area was known as the North Territory of Baja California. It has an area of 70,113 km2, or 3. 57% of the mass of Mexico and comprises the northern half of the Baja California Peninsula, north of the 28th parallel. The mainland portion of the state is bordered on the west by the Pacific Ocean, on the east by Sonora, the U. S. State of Arizona, and the Gulf of California and its northern limit is the U. S. state of California. The state has an population of 3,165,776 much more than the sparsely populated Baja California Sur to the south. Over 75% of the lives in the capital city, Mexicali, in Ensenada. Other important cities include San Felipe, Rosarito and Tecate, additionally, there is a large immigrant population from the United States due to its proximity to San Diego and the cheaper cost of living compared to San Diego. There is also a significant population from Central America, many immigrants moved to Baja California for a better quality of life and the number of higher paying jobs in comparison to the rest of Mexico and Latin America. Baja California is the twelfth largest state by area in Mexico and its geography ranges from beaches to forests and deserts. The backbone of the state is the Sierra de Baja California, where the Picacho del Diablo and this mountain range effectively divides the weather patterns in the state. In the northwest, the weather is semi-dry and mediterranean, in the narrow center, the weather changes to be more humid due to altitude. It is in area where a few valleys can be found, such as the Valle de Guadalupe. To the east of the range, the Sonoran Desert dominates the landscape. In the south, the weather becomes drier and gives way to the Vizcaino Desert, the state is also home to numerous islands off both of its shores. In fact, the westernmost point in Mexico, the Guadalupe Island, is part of Baja California, the Coronado, Todos Santos and Cedros Islands are also on the Pacific Shore. On the Gulf of California, the biggest island is the Angel de la Guarda, separated from the peninsula by the deep, the first people came to the peninsula at least 11,000 years ago. At that time two main groups are thought to have been present on the peninsula. In the south were the Cochimí, in the north were several groups belonging to the Yuman language family, including the Kiliwa, Paipai, Kumeyaay, Cocopa, and Quechan

Call sign
–
In broadcasting and radio communications, a call sign is a unique designation for a transmitter station. In North America, they are used for all FCC licensed transmitters, a call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a stations identity. The use of signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one line linking all railroad stations. In order to time, two-letter identifiers were adopted for this purpose. This pattern continued in operation, radio companies initially assigned two-letter identifiers to coastal stations and stations aboard ships at sea. These were not globally unique, so a company identifier was later added. Merchant and naval vessels are assigned call signs by their national licensing authorities, in the case of states such as Liberia or Panama, which are flags of convenience for ship registration, call signs for larger vessels consist of the national prefix plus three letters. United States merchant vessels are given call signs beginning with the letters W or K while US naval ships are assigned callsigns beginning with N, leisure craft with VHF radios may not be assigned call signs, in which case the name of the vessel is used instead. Ships in the US wishing to have a radio licence anyway are under F. C. C, class SA, Ship recreational or voluntarily equipped. Those calls follow the land mobile format of the initial letter K or W followed by 1 or 2 letters followed by 3 or 4 numbers. U. S. Coast Guard small boats have a number that is shown on both bows in which the first two digits indicate the length of the boat in feet. For example, Coast Guard 47021 refers to the 21st in the series of 47 foot motor lifeboats, the call sign might be abbreviated to the final two or three numbers during operations, for example, Coast Guard zero two one. Call signs in aviation are derived from several different policies, depending upon the type of flight operation, in most countries, unscheduled general aviation flights identify themselves using the call sign corresponding to the aircrafts registration number. In this case, the sign is spoken using the International Civil Aviation Organization phonetic alphabet. Aircraft registration numbers internationally follow the pattern of a country prefix, for example, an aircraft registered as N978CP conducting a general aviation flight would use the call sign November-niner-seven-eight-Charlie-Papa. However, in the United States a pilot of an aircraft would normally omit saying November, at times, general aviation pilots might omit additional preceding numbers and use only the last three numbers and letters. This is especially true at uncontrolled fields when reporting traffic pattern positions, for example, Skyhawk eight-Charlie-Papa, left base

Mexicali
–
Mexicali is the capital city of the Mexican state of Baja California and seat of the Municipality of Mexicali. The city maintains a highly educated and skilled population, as it has modernized, mexicalis economy has been historically based on agricultural products, and to this day it remains a large sector of the economy. As time has progressed, however, its economy has gone from being agricultural to include industry. Mexicali became the center for the aerospace industry in Mexico when Rockwell Collins established an operation there in 1966. Rockwell Collins is the oldest company under the program nationwide. The Spaniards arrived in the area crossing the Sonoran Deserts Camino del Diablo or Devils Road. This led to the evangelization of the area by Catholic missionaries, nowadays, indigenous Cocopah people still inhabit a small government-protected corner of the Colorado River delta near the junction of the Hardy and the Colorado. The Cocopah mostly work on agricultural ejidos or fishing, the early European presence in this area was limited to Anzas and subsequent Spanish expeditions across the Colorado Desert and subsequent travelers on the Sonora Road opened by them. Also the presence of the Jesuits who attempted to establish a mission in what is now Fort Yuma and they left after a revolt by the Yuma in 1781. After this, the Spanish had little to do with the corner of the Baja California Peninsula, perceiving it as an untamable. Later in the 1820s, the Mexican authorities reopened the Sonoran Road, the Sonoran Road provided a route for American fur trappers, and later American troops of Kearny and Cooke passing through the area during the Mexican–American War. Herds of cattle and sheep were driven into California across this desert trail also and this route became a U. S. This mail route remained in use until 1877 when the Southern Pacific Railroad came to Yuma making it obsolete and these sediments extended far to the west of the river itself, accumulating in a shallow basin below the Sierra de Cucapá. However, from time period until the 1880s, the area was almost completely unpopulated. However, around 1900, the area with any real population, aside from the Cocopah, were concentrated in Los Algodones. In 1900, the U. S. -based California Development Company received permission from the government of Díaz to cut a canal through the deltas Arroyo Alamo, to attract farmers to the area, the developers named it the Imperial Valley. In 1903, the first 500 farmers arrived, by late 1904,405 km² of valley were irrigated, with 10,000 people settled on the land harvesting cotton, fruits, and vegetables. The concentration of housing units that straddled the border was called Calexico on the U. S. side

FM broadcasting
–
FM broadcasting is a method of radio broadcasting using frequency modulation technology. Invented in 1933 by American engineer Edwin Armstrong, it is used worldwide to provide high-fidelity sound over broadcast radio, FM broadcasting is capable of better sound quality than AM broadcasting, the chief competing radio broadcasting technology, so it is used for most music broadcasts. FM radio stations use the VHF frequencies, the term FM band describes the frequency band in a given country which is dedicated to FM broadcasting. Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions, In the former Soviet republics, and some former Eastern Bloc countries, assigned frequencies are at intervals of 30 kHz. This band, sometimes referred to as the OIRT band, is slowly being phased out in many countries, in those countries the 87. 5–108.0 MHz band is referred to as the CCIR band. In Japan, the band 76–95 MHz is used, the frequency of an FM broadcast station is usually an exact multiple of 100 kHz. In most of South Korea, the Americas, the Philippines, in some parts of Europe, Greenland and Africa, only even multiples are used. In the UK odd or even are used, in Italy, multiples of 50 kHz are used. There are other unusual and obsolete FM broadcasting standards in countries, including 1,10,30,74,500. Random noise has a triangular spectral distribution in an FM system and this can be offset, to a limited extent, by boosting the high frequencies before transmission and reducing them by a corresponding amount in the receiver. Reducing the high frequencies in the receiver also reduces the high-frequency noise. These processes of boosting and then reducing certain frequencies are known as pre-emphasis and de-emphasis, the amount of pre-emphasis and de-emphasis used is defined by the time constant of a simple RC filter circuit. In most of the world a 50 µs time constant is used, in the Americas and South Korea,75 µs is used. This applies to both mono and stereo transmissions, for stereo, pre-emphasis is applied to the left and right channels before multiplexing. They cannot be pre-emphasized as much because it would cause excessive deviation of the FM carrier, systems more modern than FM broadcasting tend to use either programme-dependent variable pre-emphasis, e. g. dbx in the BTSC TV sound system, or none at all. Long before FM stereo transmission was considered, FM multiplexing of other types of audio level information was experimented with. Edwin Armstrong who invented FM was the first to experiment with multiplexing and these original FM multiplex subcarriers were amplitude modulated

AM broadcasting
–
AM broadcasting is the process of radio broadcasting using amplitude modulation. AM was the first method of impressing sound on a signal and is still widely used today. Commercial and public AM broadcasting is authorized in the wave band worldwide. Commercial AM broadcasting developed from amateur broadcasts around 1920, and was the commercially important form of radio broadcasting until FM broadcasting began after World War II. This period is known as the Golden Age of Radio, today, AM competes with FM, as well as with various digital radio broadcasting services distributed from terrestrial and satellite transmitters. AM broadcasting was the first broadcasting technology invented, the technology of amplitude modulation radio transmission was developed between 1900 and 1920. This was used for private communication and message traffic, such as telegrams. The entrepreneurs who developed AM radiotelephone transmission did not anticipate broadcasting voice, the term broadcasting, borrowed from agriculture, was applied to this new activity around 1920. Prior to 1920 there was no concept of broadcasting, or that radio listeners could be a market for entertainment. Although there were a number of broadcasts during this period. True radio broadcasting didnt begin until around 1920, when it sprang up spontaneously among amateur stations, AM remained the dominant method of broadcasting for the next 30 years, a period called the Golden Age of Radio, until FM broadcasting started to become widespread in the 1950s. AM remains a popular, profitable entertainment medium today and the dominant form of broadcasting in some such as Australia. The first AM voice transmission was made by Canadian researcher Reginald Fessenden on 23 December 1900, Fessenden is a significant figure in the development of AM radio. He helped develop one of the first – the Alexanderson alternator, the first practical continuous wave AM transmitters were based on versions of the Poulsen arc transmitter invented in 1903, and the huge, expensive Alexanderson alternator, developed 1906–1910. The modifications necessary to transmit AM were clumsy and resulted in low audio quality. Modulation was usually accomplished by a carbon microphone inserted directly in the antenna wire, the limited power handling ability of the microphone severely limited the power of the first radiotelephones, in powerful transmitters water-cooled microphones had to be used. At the receiving end, the crystal radio receivers then in use could not drive loudspeakers, only earphones. The discovery in 1912 of the ability of the Audion vacuum tube, invented in 1906 by Lee De Forest

Frequency
–
Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as frequency, which emphasizes the contrast to spatial frequency. The period is the duration of time of one cycle in a repeating event, for example, if a newborn babys heart beats at a frequency of 120 times a minute, its period—the time interval between beats—is half a second. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as vibrations, audio signals, radio waves. For cyclical processes, such as rotation, oscillations, or waves, in physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter ν or ν. For a simple motion, the relation between the frequency and the period T is given by f =1 T. The SI unit of frequency is the hertz, named after the German physicist Heinrich Hertz, a previous name for this unit was cycles per second. The SI unit for period is the second, a traditional unit of measure used with rotating mechanical devices is revolutions per minute, abbreviated r/min or rpm. As a matter of convenience, longer and slower waves, such as ocean surface waves, short and fast waves, like audio and radio, are usually described by their frequency instead of period. Spatial frequency is analogous to temporal frequency, but the axis is replaced by one or more spatial displacement axes. Y = sin = sin d θ d x = k Wavenumber, in the case of more than one spatial dimension, wavenumber is a vector quantity. For periodic waves in nondispersive media, frequency has a relationship to the wavelength. Even in dispersive media, the frequency f of a wave is equal to the phase velocity v of the wave divided by the wavelength λ of the wave. In the special case of electromagnetic waves moving through a vacuum, then v = c, where c is the speed of light in a vacuum, and this expression becomes, f = c λ. When waves from a monochrome source travel from one medium to another, their remains the same—only their wavelength. For example, if 71 events occur within 15 seconds the frequency is, the latter method introduces a random error into the count of between zero and one count, so on average half a count. This is called gating error and causes an error in the calculated frequency of Δf = 1/, or a fractional error of Δf / f = 1/ where Tm is the timing interval. This error decreases with frequency, so it is a problem at low frequencies where the number of counts N is small, an older method of measuring the frequency of rotating or vibrating objects is to use a stroboscope

XESPN-AM, known on-air as Cadena 800, is a Spanish language news/talk station that serves the Tijuana-San Diego area. The station came on air in April 1965 as XEMMM-AM, named for its owner, the station initially broadcast during the daytime only. XEMMM joined ESPN Radio in late 2002, replacing XETRA, which had changed from radio to adult standards some months earlier. In 2003, the sign changed to XESPN. In 2009, ESPN Radio moved to sister FM station XHMORE while XESPN joined ESPN Deportes Radio, on October 6,2010, CBC ceased sports programming on XESPN and adopted a news/talk format programmed by Grupo Imagen. ESPN Deportes Radio is now available in the San Diego-Tijuana border region on XESDD-AM1030

XERCN or RCN1470 AM is a Spanish News/Talk radio station in Tijuana. It is owned and operated by Uniradio, an operator of primarily Mexican radio stations with offices in San Diego, xEAU-AM1470 received its first concession in 1943. It soon after affiliated to the Radio Cadena Nacional network, based at 1110 AM in Mexico City, Radio Cadena Nacional was owned by Rafael Cutberto Navarro, and thus the callsign both represented the network and his own name. Many of these radionovelas are still being heard throughout the world to this day, among the most famous were its productions of Las aventuras de Kaliman and the Porfirio Cadena saga. It was also one of the few stations in Mexico that transmitted old episodes of the Cuban radio comedy La tremenda corte, Uniradio Information Query the FCCs AM station database for XERCN Radio-Locator Information on XERCN

Slogan
–
The Oxford Dictionary of English defines a slogan as a short and striking or memorable phrase used in advertising. A slogan usually has the attributes of being memorable, very concise and these attributes are necessary in a slogan, as it is only a short phrase. Therefore, it is necessary for slogans to be memorable, as well as concise in what the organisation or brand is trying to say, the word slogan is derived from slogorn which was an Anglicisation of the Scottish Gaelic and Irish sluagh-ghairm. Slogans vary from the written and the visual to the chanted and their simple rhetorical nature usually leaves little room for detail and a chanted slogan may serve more as social expression of unified purpose than as communication to an intended audience. George E. Shankels research states that, English-speaking people began using the term by 1704, the term at that time meant the distinctive note, phrase or cry of any person or body of persons. Slogans were common throughout the European continent during the Middle Ages, crimmins research suggests that brands are an extremely valuable corporate asset, and can make up a lot of a businesss total value. With this in mind, if we take into consideration Kellers research and these include, name, logo and slogan. Brands names and logos both can be changed by the way the receiver interprets them, therefore, the slogan has a large job in portraying the brand. Therefore, the slogan should create a sense of likability in order for the name to be likable. Dass, Kumar, Kohli, & Thomas research suggests there are certain factors that make up the likability of a slogan. The clarity of the message the brand is trying to encode within the slogan, the slogan emphasizes the benefit of the product or service it is portraying. The creativity of a slogan is another factor that had an effect on the likability of a slogan. Lastly, leaving the name out of the slogan will have a positive effect on the likability of the brand itself. The original usage refers to the usage as a clan motto among Highland clans, marketing slogans are often called taglines in the United States or straplines in the United Kingdom. Europeans use the terms baselines, signatures, claims or pay-offs, sloganeering is a mostly derogatory term for activity which degrades discourse to the level of slogans. Slogans are used to convey a message about the product, service or cause that it is representing and it can have a musical tone to it or written as a song. Slogans are often used to capture the attention of the audience it is trying to reach, if the slogan is used for commercial purposes, often it is written to be memorable/catchy in order for a consumer to associate the slogan with the product it is representing. A slogan is part of the aspect that helps create an image for the product
