Hello friends. Well, my first article on Radio World’s website is Radio History in the world. Why radio ??? Because radio plays a very urgent role in the growth of the sophisticated world Let’s check it out !!
Radio history in question is the history of technology that produces radio equipment that uses radio waves. Heinrich Rudolf Hertz shows Maxwell’s theory between 1886 and 1888, through experiments. And he successfully proved that radio wave radiation has wave properties (now called Hertzian waves), and pursues that electromagnetic equations can be formulated into wave equations.
After Hertz’s public works, the familiar Guglemo Marconi as the inventor of the wireless telegraph, began using the science for practical destinations. Marconi was 20 years old when in 1984 listening to Experiment Hertz in Italian magazine. A year later he was able to receive a wireless hunch within a mile of the source, and in 1896 it was 8 miles. William Abig in his book “Modern Public Opinion” states that in 1901 the methods of expedition wire markings by Marconi can be carried out across the Atlantic Ocean. Initially signals on radio broadcasts are transmitted across continuous data waves either by amplitude modulation (AM), as well as frequency modulation (FM). This method of expediting a signal is called analog. Furthermore, as the growth of technology found the internet, and digital signals that then change the radio signal transmission techniques.
The average early radio user is the maritime, who uses radio to deliver telegraph messages using morse code between ships and ships. One of the earliest users including the Japanese Navy spied on the Russian fleet during the Tsushima War in 1901. One of the most memorable uses was during the sinking of the RMS Titanic in 1912, categorized as communication between operators on ships buried by nearby ships and communications to ground station. Radio is used to stream commands and communications between the Army and
Navy on both sides in World War II; Germany uses radio communications for diplomatic messages when its submarine cable is shaved by Britain.
The United States pronounced President Woodrow Wilson’s 14th Point Program for Germany over the radio during the war. The broadcast began in the 1920s, with the popularity of radio planes, particularly in Europe and the United States. In addition to broadcast, point-to-point broadcasts were classified as telephone and re-broadcast radio programs, becoming popular in the 1920s and 1930s . The use of radio in the prewar period is to develop the detection and allocation of aircraft and ships with the use of radar. Now, the radio is not the least of its kind, belonging to wireless networks, mobile communications of all kinds, and radio broadcasting. Before the famous television, commercial radio broadcasts were classified as drama, comedy, show variety, and not a bit of other entertainment; not just news and music only. It’s funny to think if Texas Hold’em Poker was built, how would they will do the marketing back then? when they want to promote play poker or main poker from Radio, maybe the will broadcast the sound of the play and the bluff.
The history of broadcast media can be broken down into two parts: the history of broadcast media as the invention of technology and the history of broadcast media as an industry. The history of broadcast media as a technological invention stems from the discovery of radio by experienced engineers in Europe and America. The history of broadcast media as an industry opened in America. Want to know about more? don’t forget to join our upcoming event, register yours now.
The radio broadcasting industry was started by David Sarnoff who established the AM radio system aircraft company that has the name RCA or Radio Corporation of America. Coverage of election work in the year 1920 by Radio KDKA (USA) perceived as broadcast news broadcasting widely and regularly for the community. KDKA Radio is a commercially licensed radio broadcasting station founded by Frank Conrad
The development of the FM radio broadcasting industry opened in mid-1933, Edwin Howard Armstrong of Columbia University successfully discovered the modulation frequency (FM), a much higher frequency of radio broadcasting AM (ie from 88 to 108 MHz). Armstrong then demonstrated his discovery to David Sarnoff. But RCA was more interested in developing television. Armstrong then sold it to a number of other companies. The development of FM radio was delayed because of the outbreak of World War 2 and the industry more interested in developing television.
The FM advantage of AM is:
May eliminate “interference” caused by weather, sunspots or electrical devices.
Can broadcast sound as well as possible
