How to Buy the Best Radio? A Detailed Beginners Guide

Radio – we everyone knows about it. The kids of ’70s and 80’s love it as much big, wherein those who have a radio at home receive super welcome.

What does Radio Mean?

Radio is a technological device, which carries information as sound waves (radio waves). Scientifically, it modulates the properties of electromagnetic energy through amplitude, frequency, &phase width. (1)

In fact, the term ‘radio’ comes from the Latin word ‘radius’, which means ‘spoke of the wheel or a beam of light/ray’. The French scientist Ernest Mercadier used it in communications in the year of 1881. Wherein, Alexander Graham Bell adopted the term ‘radio phone’ – meaning ‘radiated sound’ as another term for his transmission system ‘photo-phone optical’. However, not all those inventions were adopted widely. (2)

What is the Science Behind it?

An actual radio communication system requires a transmitter and a receiver wherein the radio waves strike the electrical conductor; hence, an oscillating field induces an alternate current in the conductor. It happens through each antenna with a suitable terminal device say for the microphone. The loudspeaker at the receiver end translates the information in terms of sound. Hence the radio works.

Radio devices in communication usage have a certain set of elements, which you will never come to know about it. With more than decades of development, each phase has a broad range of methods, experiments, implementations, and different levels of communication purposes.

The ‘Father of Radio’ is Guglielmo Marconi who sent the first radio transmission in 1896. The first transatlantic experimental radio communication happened in 1901 & 1902 by Marconi. However, in 1900, Reginald Fessenden made a weak transmitted voice over the airwaves. In 1903, Marconi helped the then US President Roosevelt in sending a radio message to Edward VII. Marconi won Nobel Prize for his dedicated contributions for the development of wireless telegraphy in 1909. (3)
