1. 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
2. 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
3. Radio station – A radio station is a set of equipment necessary to carry on communication via radio waves. Generally, it is a receiver or transmitter, an antenna, Radio stations play a vital role in communication technology as they are heavily relied on to transfer data and information across the world. More broadly, the definition of a radio station includes the aforementioned equipment, such a station may include several radio stations defined above. This definition of a station is more often referred to as a transmitter site. Each station shall be classified by the service in which it operates permanently or temporarily», transmitter - Takes the electrical output of a microphone and then modulates a higher-frequency carrier signal and transmits it as radio waves. Receiver - The broadcast message is received by the receiver and decodes the radio sine waves, antenna - An antenna is required for transmission, it is also required to receive radio waves. The main use of an antenna is to radio signals. Aerial feeder - system of feeding HF-Energy in the antenna Transmission lines - Transmission lines are used to transfer the radio signals from one location to another. For example, a line was used in Luftwaffe, Germany during WW II to send information from camps back to their base. Connectors Interface panel remote control – This is used to various different types of the equipment used in a radio station. To input broadcast data into a transmitter an interface panel will need to be used, cable – A cable can be used to connect the various devices. Equipment Rack – To hold all equipment in a secure and logical manner, power protection equipment – For holding equipments in a stable, secure and logical manner. UPS – For uninterrupted power supply and these are the most used/important devices and items for most radio stations. A microphone is used to capture the input of sound created by people speaking into the device. The sounds are turned into electrical energy, this energy then flows along a metal antenna. As the electrons in the current move back and forth up the antenna. The waves travel at the speed of light, taking the program with them. A compound of both a transmitter and a receiver is called a transceiver, they are combined and share common circuitry or a single housing, when no circuitry is common between the transmit and receive functions, the device becomes a transmitter-receiver
4. San Diego – San Diego is a major city in California, United States. It is in San Diego County, on the coast of the Pacific Ocean in Southern California, approximately 120 miles south of Los Angeles and immediately adjacent to the border with Mexico. With an estimated population of 1,394,928 as of July 1,2015, San Diego is the eighth-largest city in the United States and second-largest in California. It is part of the San Diego–Tijuana conurbation, the second-largest transborder agglomeration between the US and a country after Detroit–Windsor, with a population of 4,922,723 people. San Diego has been called the birthplace of California, historically home to the Kumeyaay people, San Diego was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the area for Spain, the Presidio and Mission San Diego de Alcalá, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly independent Mexico, in 1850, California became part of the United States following the Mexican–American War and the admission of California to the union. The city is the seat of San Diego County and is the center of the region as well as the San Diego–Tijuana metropolitan area. San Diegos main economic engines are military and defense-related activities, tourism, international trade, the presence of the University of California, San Diego, with the affiliated UCSD Medical Center, has helped make the area a center of research in biotechnology. The original inhabitants of the region are now known as the San Dieguito, the area of San Diego has been inhabited by the Kumeyaay people. The first European to visit the region was Portuguese-born explorer Juan Rodríguez Cabrillo sailing under the flag of Castile, sailing his flagship San Salvador from Navidad, New Spain, Cabrillo claimed the bay for the Spanish Empire in 1542, and named the site San Miguel. In November 1602, Sebastián Vizcaíno was sent to map the California coast, in May 1769, Gaspar de Portolà established the Fort Presidio of San Diego on a hill near the San Diego River. It was the first settlement by Europeans in what is now the state of California, in July of the same year, Mission San Diego de Alcalá was founded by Franciscan friars under Junípero Serra. By 1797, the mission boasted the largest native population in Alta California, with over 1,400 neophytes living in, Mission San Diego was the southern anchor in California of the historic mission trail El Camino Real. Both the Presidio and the Mission are National Historic Landmarks, in 1821, Mexico won its independence from Spain, and San Diego became part of the Mexican territory of Alta California. In 1822, Mexico began attempting to extend its authority over the territory of Alta California. The fort on Presidio Hill was gradually abandoned, while the town of San Diego grew up on the land below Presidio Hill. The Mission was secularized by the Mexican government in 1833, the 432 residents of the town petitioned the governor to form a pueblo, and Juan María Osuna was elected the first alcalde, defeating Pío Pico in the vote
5. San Diego County, California – San Diego County is a county in the southwestern corner of the state of California, in the United States.

Its county seat is San Diego, the eighth-most populous city in the United States and it is the south-westernmost county in the 48 contiguous United States. San Diego County comprises the San Diego-Carlsbad Metropolitan Statistical Area, San Diego is also part of the San Diego–Tijuana metropolitan area, the largest metropolitan area shared between the United States and Mexico. Greater San Diego ranks as the 38th largest metropolitan area in the Americas, San Diego County has 70 miles of coastline. Most of the county has a mild Mediterranean climate to climate, though there are mountains that receive frost. There are also 16 naval and military installations of the U. S. Navy, U. S. Marine Corps, and these include the Naval Base San Diego, Marine Corps Base Camp Pendleton, Marine Corps Air Station Miramar, and Naval Air Station North Island. From north to south, San Diego County extends from the borders of Orange County and Riverside County to the Mexico–United States border. From west to east, San Diego County stretches from the Pacific Ocean to its boundary with Imperial County, the area which is now San Diego County has been inhabited for more than 10,000 years by Kumeyaay, Luiseño, Cupeño and Cahuilla Indians. In 1542, the Portuguese-born explorer Juan Rodríguez Cabrillo, sailing for Spain, claimed San Diego Bay for the Spanish Empire, and he named the site San Miguel. In November 1602, Sebastián Vizcaíno surveyed the harbor and what are now Mission Bay and Point Loma and named the area for Saint Didacus, a Spaniard more commonly known as San Diego. European settlement in what is now San Diego County began with the founding of the San Diego Presidio and Mission San Diego de Alcalá by Spanish soldiers and this county was part of Alta California under the Viceroyalty of New Spain until the Mexican declaration of independence. From 1821 through 1848 this area was part of Mexico, San Diego County became part of the United States as a result of the Treaty of Guadalupe Hidalgo in 1848, ending the U. S. -Mexican War. San Diego County was one of the counties of California. At the time of its establishment in 1850, San Diego County was relatively large, as such it included areas of what are now Inyo County and San Bernardino County, as well as all of what is now Riverside County and Imperial County. During the later part of the 19th century, there were changes in the boundaries of San Diego County. The most recent changes were the establishments of Riverside County in 1893, according to the U. S. Census Bureau, the county has an area of 4,526 square miles, of which 4,207 square miles is land and 319 square miles is water. The county is larger in area than the states of Rhode Island
6. California – California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565
7. KBRT – KBRT is a Southern Californian Christian radio station. It airs Christian talk radio programming from Costa Mesa, California to Los Angeles, Orange County, the Inland Empire, San Diego, the station broadcast at 10,000 Watts sunrise to sunset at 740 kHz.

The studio and business offices remain located in Costa Mesa, KBRT is a Class D station broadcasting on the Canadian clear-channel frequency of 740 AM. CFZM in Toronto, Ontario, Canada is the dominant North-American station on 740 AM, KBRT is licensed by the U. S. Federal Communications Commission to broadcast in the HD format. The station went on air in 1952 and it was founded by entrepreneur John H. Poole as KBIG. Poole had worked at KEZY Anaheim, California, and was founder of channel 22 KBIC-TV in Los Angeles, studios were located at the transmitter site on Avalon, later on the mainland coast. From the beginning there were disagreements with co-channel KCBS San Francisco over interference between the stations. Much of the path between stations wavefronts was over highly conductive seawater, according to Billboard Magazine, Bonneville Communications owned KBRT prior to the sale to Crawford Broadcasting. Bonneville, owned by the Church of Jesus Christ of Latter-day Saints, has dabbled on, Bonneville owns KSWD, The Sound at 100.3 FM. Just prior to the switch, KBRT played Contemporary Christian Music from sunrise to sunset, the daily sign-on began with a recording of a mans voice, Good morning. This is K-B-R-T Avalon, and we now begin another day of broadcasting over Southern California, K-B-R-T radio broadcasts on an assigned frequency of 740 kilohertz with a power output of 10,000 watts by authority of the Federal Communications Commission. K-B-R-Ts transmitter was, at the time, located on Santa Catalina Island, air personalities have included Clark Race, Johnny Magnus, Paul McGuire, Rich Buhler, Dave Sebastian Williams and Program Director, Mike Trout. Magnus featured his trademark Weather With a Beat, where he would list U. S. a typical background music track for Weather With a Beat was Count Basies version of Neal Heftis tune, Cute, featuring Frank Wess on flute. Previously, KBRT was known as KBIG, airing Easy Listening music, contractors cutting a steel antenna cable with a gas-powered circular saw caused the wildfire that began on May 10,2007. KBRT had to shut down the transmitter, which was not damaged, until the transmitter was repaired, the station aired only on KBRT740. com. Housholder exited The Bottom Line in April 2013, the Bottom Line reaches most AM radios in California, since it is syndicated on KCBC770 AM in the Sacramento/Bay Area region

9. KCBQ – KCBQ is a commercial AM radio station in San Diego, California. It is owned by Salem Communications and airs a radio format. Studios and offices are on Towne Center Drive in San Diego, the transmitter is off Moreno Avenue in Lakeside, California. By day, KCBQ operates at 50,000 watts, the power for American AM stations. It uses an antenna at all times. Some hours on weekdays and weekends are paid brokered programming, weekends feature shows on money, health, food, law and cars. Some hours are paid brokered programming, KCBQ had been a Top 40 powerhouse in the 1950s, 1960s and 1970s, later airing Country music and Oldies formats in the 1980s and 1990s, before switching to talk. 1170 first signed on the air in 1946 and its original call sign was KSDJ. The station began broadcasting from its first studio at 5th and Ash, in 1949, KSDJ was sold to Charles Elliot Salek and became San Diegos second CBS network affiliate. To coincide with the new affiliation, the KSDJ call letters were changed to KCBQ. The call letters KCBS were sought, but the CBS network wanted them for its network-owned San Francisco affiliate, an agreement was reached and Salek settled for K-Columbia-Broadcasting-Quality. In 1951, KCBQ moved its studios to the Imig Manor Hotel on El Cajon Blvd, KCBQs transmitter site was next to the Campus Drive-In at El Cajon Boulevard and College Ave. The drive-in was demolished in the late 1970s and is now the Campus Shopping Center, KCBQs power until 1958 was 5,000 watts non-directional day and 1,000 watts non-directional night. The station used an RCA BTA-5F5,000 watt transmitter at the College site, KFSD used the same model transmitter. Bartell Family Radio bought KCBQ in 1955 and dropped the CBS affiliation as network radio was losing its luster in the face of competition from television and those studios are dedicated in 1957 with a live broadcast from an outdoor stage featuring the music of Bill Greens Big Band. The new studios had a picture window studio that looked out over the street so that fans could watch their favorite disc jockeys on the air. There was even a mirror mounted over the console so that from the street you could watch the DJs every move at the controls, the studios were featured in Life Magazine in 1958.
