Amateur radio is a
community of people that use radio transmitters and receivers to
communicate with other Amateur radio operators. The things that
amateur radio operators do with their radios are as
the people themselves.
operators are often called ham radio operators or simply "hams." (The
origin of this nickname is for all practical purposes lost. Although
some people still speculate about, few agree and even few care.
Amateur radio operators proudly call themselves hams and nobody knows
why.) There are about 15000 thousand hams in India.
Radio is both a Hobby activity and Service. It is an activity of Self
Learning, Inter-Communication & Technical Investigation carried on the
duly authorized persons (i.e. Amateur Radio Operators) for a personal
aim and without pecuniary interest. There are over 30 lakh people all
over the world who pursue this activity in their free time, in India
we have around 15000 amateur radio operators.
Operators have to qualify in an examination conducted by Ministry of
Communications, Government of India and obtain license for operating /
possessing a Radio Station.
operators in their free time use their radio stations and conduct
two-way communication and exchange cultural, personal, technical
information with other amateurs not only within India but all over the
world. The two-way communications using Radio Transmitters, receivers,
antennae can be either through Voice, Morse Code, Digital (Video &
Data) or through Satellites.
