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.

The reason why an amateur radio operator is
called a 'ham' is not known. Some relate these three letters
(HAM) to the names of three great radio
experimenters. 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)

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.
