What is Amateur Radio


Amateur radio is a form of two-way radio communication for recreation and
community service. Amateur radio operators are commonly known as hams.
“hams” in India must be licensed by the WPC, department of communication,
government of India. Amateur radio operators can make contacts worldwide, and
even with astronauts in space! Their extra effort is well – rewarded! It is an exciting
way to discover new friends and disseminate knowledge.
The amateur radio service (amateur service and amateur-satellite service) is
established by the International Telecommunication Union (ITU) through the Radio
Regulations. National governments regulate technical and operational
characteristics of transmissions and issue individual stations licenses with an
identifying call sign. Prospective amateur operators are tested for their
understanding of key concepts in electronics and the host government’s radio

Radio amateurs use a variety of voice, text, image, and data communications
modes and have access to frequency allocations throughout the RF spectrum. This
enables communication across a city, region, country, continent, the world, or
even into space. In many countries, amateur radio operators may also send,
receive, or relay radio communications between computers or transceivers
connected to secure virtual private networks on the Internet.

Amateur radio is officially represented and coordinated by the International
Amateur Radio Union (IARU), which is organized in three regions and has as its
members the national amateur radio societies which exist in most countries.
According to an estimate made in 2011 by the American Radio Relay League, two
million people throughout the world are regularly involved with amateur radio.[2]
About 830,000 amateur radio stations are located in IARU Region 2 (the Americas)
followed by IARU Region 3 (South and East Asia and the Pacific Ocean) with about
750,000 stations. A significantly smaller number, about 400,000, are located in IARU
Region 1 (Europe, Middle East, CIS and Africa).

Amateurs use a variety of voice, text, image, and data communications modes
over radio. Generally new modes can be tested in the amateur radio service,
although national regulations may require disclosure of a new mode to permit radio
licensing authorities to monitor the transmissions. Encryption, for example, is not
generally permitted in the Amateur Radio service except for the special purpose of
satellite vehicle control uplinks. The following is a partial list of the modes of
communication used, where the mode includes both modulation types and
operating protocols.

  • Will inculcate the communication and leadership skills.

   The world is not a very safe place to live in these days as disaster and terrorism can
strike at any moment. Communication is the only relief as times of disaster and
hence the need for an efficient disaster management system becomes imperative
in public places and even in business establishments and important commercial
joints where people move around in large numbers. Disaster might strike in the form
of natural calamities, terrorist’s attacks and accidents. Thus an efficient disaster
management system which will work in adverse conditions is needed. In times of
natural calamity like floods, storms or fire the usual mode of communication like
phone, mobile etc. might not work or might be lost in the calamity.

   Whatever be the situation, one cannot rely transporting fuel to keep the power up
for vital facilities since the power lines could be snapped (often seen in
photographs) with uprooted trees and power lines and towers twisted and broken
completely, or simply there is no road to the generators – either due to floods, or
due to various obstacles like trees, or damaged roads or bridges.
   Disasters are extreme events which result in widespread social disruption, trauma,
property damage and loss of life. A number of natural hazards have resulted in
disasters. India has been traditionally vulnerable to natural disasters on account of
its unique geo-climatic conditions. Floods, droughts, cyclones, earthquakes and
landslides have been a recurrent phenomenon. About 60% of the landmass is
prone to earthquakes of various intensities; over 40 million hectares is prone to
floods; about 8% of the total area is prone to cyclones and 68% of the area is
susceptible to drought. The super cyclone in Orissa in October, 1999 and the Bhuj
earthquake, Gujarat in January, 2001, Tsunami in 2005 underscored the need to
adopt a multi-dimensional endeavour involving diverse scientific, engineering,
financial processes; the need to adopt multi-disciplinary and multi sectoral
approach incorporation of risk reduction in the developmental plans and
