WORLD RADIO DAY 2020 | Know about History and Use of Radio

 

Every year on February 13, World Radio Day is celebrated depicting the radio as a way of educating people, providing information, and promoting freedom of expression worldwide across cultures and people. This year, on 13 Feb 2020, the United Nations Educational, Scientific and Cultural Organization (UNESCO) are celebrating the ninth edition of World Radio Day. These days, people around the world celebrate the radio and how they shape everyone’s lives.

According to UNESCO, “Radio is the perfect medium for spreading allegations of violence and conflict, especially in the majority of the region.” The word “broadcast” was originally used to describe radio broadcasts. Gesturing was a farming term that meant the spread of seeds. Radio is a powerful tool that informs, transforms, and connects you with people and communities of all backgrounds and encourages positive communication about change.

 

Let’s Start with – WHAT IS RADIO?

Radio is a method of transmitting electromagnetic signals over long distances to deliver information from one place to another. Machines that transmit radio signals are called transmitters, and machines that “pick up” the signal are called receivers. The machine that performs both jobs is a “transceiver.” When a radio signal is sent to many receivers at the same time, it is called a broadcast.

Televisions also use radio signals to transmit images and sound. The radio signal drives the engine so that the gate opens on its own from a distance. The car signal can be locked and unlocked from a distance using radio signals.

The sound can be transmitted on the radio, sometimes with the frequency modulation (FM) or amplitude modulation (AM).

Radio is based on human voice and is a uniquely personal medium that allows listeners to imagine the mental image around the broadcast sound. Radio can comfort listeners through speech, and background music much easier and more extensively than any other media. Radio has no boundaries between entertaining and entertaining sounds and musical effects. Since the birth of the media, private broadcasters and the government agencies have consciously used their unique qualities to create programs to attract and retain listeners.

HISTORY OF RADIO

Many people worked to make the radio viable. Heinrich Rudolph Hertz of Germany first showed there were radio waves after James Clerk Maxwell predicted. In Italy, Guglielmo Marconi made radio a practical tool for telegraphy, mainly used by sea ships. Later inventors learned to transmit sounds, which led to the transmission of news, music, information, and entertainment.

Historically, Marconi started broadcasting the radio in 1896 – the first wireless link was invented. Then it took the first 10 years, establishing radio broadcast performance, but difficult to identify words from the music. Another successful performance took place from the Eiffel Tower in Paris, New York stations broadcast the first radio breaking news in 1916 when the United States President is elected in 1927. It was started as an important information medium.

Indian radio broadcasting began as a private company in 1923 and 1924, there are three radio clubs in Bombay, Kolkata, and Madras (currently Chennai). Radio Club launched its first radio program in India in June 1923. The two- to three-hour broadcast each day consists mainly of music and conversation. These stations had to be closed in 1927, due to insufficient financial support. After that, we started broadcasting service experimental test broadcast in Bombay, India, in July 1927. A month later, according to an agreement between the Indian governments in Kolkata, Indian Broadcasting Company Limited faces a private company’s widespread anger. Acquired assets and established Indian Broadcasting Service Ministry of Labor. Since then, it has been broadcast in India

The government was under control. In 1936, a radio station was established in Delhi. In the same year, The Indian broadcast service has been renamed All India Radio (AIR). A signature song was added. Delhi’s station has become the center of broadcasting. At the national level, All India Radio has been a huge success since June 1936. Independently, the airline network had only six stations in Delhi, Bombay and Kolkata, Madras, Lucknow, and Tiruchirappalli, 6 transmitters-6 transmitters. These cities were restricted to urban elites with its emergence; radio broadcasting has become increasingly important.

During the Second World War, news and political commentary were introduced and published separately; the whole country was covered by shortwave services. By 1939, the structure of the program has changed in terms of wartime uncertainty.

After independence, the broadcasting scene has changed significantly198 broadcast stations, including 74 local radio stations 97.3% of the country’s population. We are a broadcasting program now many languages ​​all day. Operation of All India Radio in an unparalleled sense, this is probably just a press. The main broadcaster is a complete station with a network medium wave, short wave, FM transmission. In addition, external services aerial partitions are links to various parts of the world through in-programs About 72 hours, 24 languages ​​a day.

 

CURRENT SCENARIO OF RADIO:

Currently, radio and satellite services are used to broadcast programs nationwide. With the launch of the radio paging service, FM transmitters have become airborne milestones. Today, All India Radio is one of the world’s largest broadcast networks that meet the mass communication needs of Indian masses. The network gradually expanded to include new and programming technologies.

Three-layer broadcasting: All India Radio has launched a three-layer broadcasting system nationwide, regional, and local. The educational and recreational needs of people in different parts of the country, they spread throughout the length and breadth of the country. News, music, talks, and other programs are available nationwide in 24 and 146 languages. Local and sub-region stations in different states are the center of the broadcast. Local radio and community radio is relatively new concepts of Indian broadcasting. Each station serving a small area provides utility services and reaches the center of the community.

 

REACH OF RADIO

All Indian radios are now part of Psarar Bharati, an Indian autonomous broadcaster under the Parliament Act of 1990. The Prasar Bharati Commission took over the administration of All India Radio on November 23, 1997. Currently, All India Radio has more than 183 radio stations, 183 full stations, 9 relay centers, and 3 Vivid Bharati commercial centers. All radios have 310 transmitters, providing a wireless, coverage for 97.3% of the country’s 90% population. All India Radio’s External Services Division is an important link between India and the world, broadcast in 25 languages. Of these, 16 are foreigners and 9 are Indians. The national channel of All India Radio was aired on May 18, 1998. The channel operates as a night service from 6:50 pm. By 6:10 am every day, it covers 64% of the area and about 76% of the population.

USE OF RADIO

Radio was initially created as a way to send telegraphic messages between two people without wires, but soon two-way radios communicated with vocals such as transceivers and ultimately mobile phones.

One of the main uses today is to broadcast music, news, and entertainment such as “talk radio”. The radio program was used before the TV program appeared. In the 1930s, the President of the US began sending a weekly message to American people about the country. Companies that produce and transmit radio programs are called radio stations. These may be run by the government or private companies that send advertising and make money. Other radio stations are supported by the local community. These are called community radio stations. In the early days, construction companies were paying to broadcast the complete story on the radio. These were often plays or comedy-dramas. These were called “soap operas” because the soap companies often pay for them.

Radio waves are still used between peoples. Talking to someone who has a radio is different from “talk radio”. Citizens Band Radio and Amateur Raw Dio have special radios everywhere. They use wireless emergency communication systems (talk to each other) to communicate with police, firefighters, and other people in emergencies. It’s like a mobile phone (and uses radio signals), but the range should use the same type of radio.

The term “wireless” means only voice band transmission. Audio-band broadcasting uses lower frequencies and longer wavelengths than most television broadcasts. Microwave frequencies are even higher. They are used for other purposes, such as broadcasting, television and radio programs. Communication satellite microwave relays worldwide.

The radio receivers do not need to be transmitted directly to receive the program signal. Repeater stations are often used to improve signal quality, but low-frequency radio waves can be found around the hill.

Short-wave radio frequencies are reflected from the charged layer of the upper atmosphere, known as the ionosphere. Due to the curvature of the Earth’s surface, waves can reach nonlinear receivers between the ionospheres and the Earth. They can go a long way, sometimes all over the world.

Radio telescopes receive radio waves from the sky to study astronomy. Satellite navigation radio is used to determine location, and radar is used to track and track objects.

FUTURE OF RADIO

In developing countries such as us, the specific function of broadcasting should be the scope of development, its importance, benefits, and issues. It highlights people’s participation in development activities and important work done by voluntary institutions. The style and manner of news reporting must reinforce the basic principles of national policy. The main purpose of current affairs programs is to educate people on various aspects of political, economic, social, and cultural development. FM and radio privatization: In recent years, there have been two important developments in the field of Indian radio, and television broadcasting. With the advent of television, the importance of radio has gradually diminished.

This actually happened for a few years and significantly reduced radio ownership and radio listenership. But radio seems to become the back once again in the form of FM broadcasts. FM’s transmission stations are acting as local stations catering to the local needs of listeners. The partial privatization of FM broadcasting has also made radio an important medium of mass communication. Programs broadcast on FM are becoming very popular with urban youth as the programs specifically cater to them. In addition, FM broadcasts are also becoming popular in cars and other vehicles. They provide essential information to motorists about obstacles, traffic, and weather, etc. FM broadcasting has gained a lot of popularity over the years.
