HAM RADIO

What is HAM Radio?
Ham radio operators are a group of people nurturing a special interest in wireless communication technology.  People from all the spheres of life are found among the ham radio operators. They operate their wireless transceivers (a combined unit of radio transmitter and receiver) during their pastime for the sheer joy, thrill and excitement involved in doing  worldwide radio communication. Unlike the broadcast radio stations (to whom we usually tune our radio receivers to listen to), ham radio is a two-way communication system. Ham radio operators can put their voice on-the-air to be listened into and at the same time replied back by their fellow radio operators around the world.      ..More...

They are- Hertz (who practically demonstrated the existence of electromagnetic waves in 1888), Armstrong (who developed a resonant oscillator circuit for radio frequency work) and Marconi (the 1909 Nobel laureate in Physics, who in the year 1901 established the first transatlantic radio contact)    ...More..           
Utility of HAM Radio
 A ham radio operator can carry on experiments with various communication equipment and systems going deeper into the science of electronics (Learning by Doing) and at the same time provide great service to the people in general worldwide by way of organizing on-the-air emergency medical traffic, establishing emergency communication network during natural calamities like flood, cyclone, storm, earthquake or any other disaster. Amateur Radio stations act as the 'SECOND LINE' of communication when existing public or government communication links fail to act. ..More..
