Cesar+-+Radio

 Hello there boys and girls! i am here to talk to you about something amazing and that had big change in life and society. I am here to talk to you about radio, the thing that plays music in your car or in your little boombox. Radio wasnt just for listening to usic. It was also used for communications, picture messaging. Radio made life easier with their communications, and entertaining with music. The radio was first installed in the Fessenden station at Brant Rock, Mass. Christmas Eve of 1906. It was enabled that station to transmit a radio broadcast which included a voice and violin solo. Henrich Hertz proved the Physical existence of radio waves that Maxwell has shown but in a mathematical way. Federal Radio Commission's action was most significant development in broadcasting regulation in December, which authorized the Widening of the broadcasting band of wave lengths to embrace the range from 1500 to 1600 kilocycles. Some wave lengths are called micro-waves because they normally travel in straight lines of sight. (source1 )

Before this great idea came up; communication was only dots and dashes transmitted by inefficient crashing spark machines. After 2 years of experimenting, Alexander finally invented a 2-kilowatt, 100,000-cycle machine. Eventually the broadcasting went from 100 watts to 1.5w, its coverage increased greatly. Henrich Hertz’s transmitter consisted of a simple spark gap across an induction coil with a loop of wire to act as an antenna. The receiver consisted of a smaller gap in a loop the same size as the transmitter. Some wave lengths are called micro-waves because they normally travel in straight lines of sight, like searchlight beams (source 5)

Edwin Armstrong, 11 years old when he heard about Marconi’s trans-Atlantic transmission occurring. This quickly fired up Armstrong’s imagination; he soon became a creator of homemade wireless equipment. During his teenage years his parents allowed him to build a 125 foot antenna in the yard so he could get more info about his studies on radio. When he was 16 when Deforest announced his Audion tube and one these fagile, expensive tubes was added to his "study equipment". In January 1933 Marconi has announced his successful experiments. He was able to send voice and code along directed paths in the ether, using wave lengths as short as fifty-seven centimeters, stimulated world-wide interest in the potentialities residing in such extremely short waves. (source 5) May 1922 the Marconi Company was allowed to set up a broadcast station in London. Later that year the British broadcasting company was formed and took over the station and called 2LO. Eventually the broadcasting went from 100 watts to 1.5w, its coverage increased greatly. Westinghouse Company set up a short broadcasting station called KDKA in eastern Pittsburgh which transmitted a length of 62.7 meters. An amateur station called 2NM run by Gerald Marcuse started broadcasting in 1927. Theses 2 stations gained alot of fame during the time and shortly after the station BBC started from an experimental station. It took until 1932 before empire service BBC was officially opened, broadcasting from Daventry in the Midlands. According to the Radio Manufactures Association, there are a few more than fifty licensed manufacturers of radio equipment-companies holding patent licenses from all sorts of patent-controlling concerns to install them to produce modern receiving apparatus. In 1933 the number of employees in the radio manufacturing industry were around 50,000 to 60,000. There are many more small unlicensed radio-set producers. (Source 5) October 4th 1957, the USSR launched their first satellite into orbit. The satellite was slow and low alltitude, it took 96 minutes to circle around the earth. It only transmitted a bleep, but it was successful and sufficient and proved that satellites could be put into orbit successfully.(source 5)

The broadcasting started in February 1920. Although only two programs were broadcasted daily, it still made a huge impact. The famous international singer Dame Nellie Melba took part in the one on June 20, 1920. This was a major blow to thousands of "amateur or "ham" radio operators that were just starting out. Many of these men, like Armstrong, joined the army, Navy, or Merchant Marine so they can put the grateful talents to work for the U.S. Stations who are using those wave lengths must not only induce the radio manufacturers to bring out standard sets that will take in those waves. They allowed R.C.A. a "picture message" system of sending written and printed matter between 2 cities by radio in predicated upon the use odd wave lengths between 86,000 and 400,000 meters.

archlight beams.1917 the U.S went to war (WWI). The Federal government shut down all private radio operations in the United States, the Titanic disaster had a role in this (Radio Act of 1912). This shutdown wouldn’t be as a big deal as it is today since commercial broadcastings weren’t cancelled; commercial broadcasting didn’t start till 1920.

James Clerk Maxwell; proved his invention mathematically and published his research in papers. His earliest work(s) was performed while he still in Kings College London. His work was later shortened it down into a book called "Treatise on Electricity and Magnetism." Maxwell move to Cambridge in 1871, and then became the first director of the Cavendish Research Laboratory.

Without radio we wouldn’t be able to communicate with others, we wouldn’t be able to enjoy entertainment. Radio made a huge impact on society, mostly with communications mostly after that act of 1912 when a ship only had one radio for communication and it was turned off. Radio also led into other things like the IPod with is a big thing today, or cellphones and cellphones have made a huge impact on our society too! And communication device like the phone or to IPods all connect back to radios. Where would we be without music? I think the world would be a mistake without music.
