Radio Broadcasting’s Vital Role in Emergencies

Radio has been started long back ago; it includes all the modern techniques of communication and technologies, which have already been explained in the radio magazine. Radio has always been an important source of information for all sort of work like emergencies, news, songs, etc. radio has also been a great source of entertainment too in day to day basis.

The most critical date in the history of radio is 1920, in which the basis of public network broadcasting and even early TV programming was launched. In 1925 the scientists were inventing TVs so as to show radio audio with the video. First off, all the radio was transmitted in an audio transmission that was also known as a.m. To overcome the interference in sound transmission, FM was launched in the year 1930s. In FM, the radio waves were transmitted through the air with the antennas. In the early 2000s, the Americans were introduced with digital radio and direct broadcasting by satellite, also known as DBS.

Radio used in emergencies

By the year 1930, radio and TVs were an integral part of American life. All the emergencies were first announced on the radio so as to keep the people safe. It was announced as a warning.

In those days, the radio used to transmit news, emergencies in a type of code that was known as Morse code, which was an on-off tone that introduced communication on telegraph lines, undersea cables, and radio circuits for emergency signals.

In a life-threatening situation like fire, explosion, sinking vessel, or aircraft, there were Morse codes announced thrice simultaneously, which were mayday, mayday, mayday. With this type of Morse code, people used to know that there is an emergency, and they used to be more cautious and careful than before.

 Ham radios were used with some set frequencies in which some channels were available, usually for commercial, police, and government use only.

By this means of communication, they could communicate one way or two-way communication by the year 1940s.  The ham radio as a means of communication, information of emergency is passed on to a broader range of people and so that it is a warning kind of thing. It was also used at the time of natural disasters like earthquakes, landslides, drought, tsunami, etc.

During the titanic was drowning, the people on the ship used ham radio to get some help from the other people so that they could be saved. The amateur distress was sent in the year 1912 in the month of April.

In the late 1950s, the method used for emergency broadcasting for the public was CONELRAD, also known as control of electromagnetic radiation, and later on, the method of emergency broadcasting for the public was changed by the emergency broadcasting system also known as EBS in the year 1960s. Then at the later stage, it was altered to an emergency alert system, which was also known as EAS in the year 1990s.

In today’s life, radio has been very informative due to its channels, and also it spreads awareness among the people so that the people are more careful as safety is everyone’s priority. In FM, the radio waves were transmitted through the air with the antennas. In the early 2000s, the Americans were introduced with digital radio and direct broadcasting by satellite, also known as DBS.

Radio has always been an important source of information for all sorts of work, like emergencies. Radio has been started long back ago; it includes all the modern techniques of communication and technologies.

It has always been a mass of communication with all the public present in a country as it gives information about severe weather and even threats related to wars. If there is a power cut and you can’t access anything, still radios will be accessible in the power cut too.

CONCLUSION

First off, all the radio was transmitted in the audio transmission that was also known as AM. To overcome the interference in audio communication, FM was launched in the year 1930s.  Radio has always been an essential source of information for all sort of work like emergencies, news, songs, etc. radio has also been a great source of entertainment too in day to day basis. The ham radio was basically a means of communication so that the information of emergency is passed on to a wider range of people and so that it is a warning kind of thing.
