Talk to the world
By Abhishek Rathi
Gardening is a hobby for the patient, stamp collecting for the
adventurous, kayaking for the dare
devil; and then theres Amateur Radio for everyone.
Amateur radio operators are commonly called HAM radio operators
or just HAMs. The term HAM
came about after three amateur radio enthusiasts setup their own
amateur radio station at Harvard.
They were respectively Albert Hyman, Bob Almy and Peggie Murray.
When laws to regulate amateur
radio were being passed in the UK in 1911, Hyman spoke up to
make the laws more liberal else the
heavy taxes would have killed amateur radio due to heavy
commercialization. The first initials of the
last name of the three operators became popularized by other
amateur radio operators and the
initials HAM stuck on for all modern amateur radio
operators.
HAM radio offers a piece of its pie for everyone. It caters to
the hobbies of people who love to talk
& meet new people, play with electronics, invent new radios,
like to keep company while travelling,
communicate directly via satellite, to just learn and many more.
HAMs are a medium of free speech.
In 2001, HAM radio operators came to the rescue when the Gujarat
earthquake struck. In 2004,
when the Indian Ocean tsunami struck the Andaman and Nicobar
islands, HAM radio was the only
mode of communication. HAMs play a vital role in disaster
management when infrastructural
communication systems are down.
There are about six million licensed HAMs all over the world and
sixteen thousand in India. HAM
radio became popular in India in the 90s when the Indian
government lifted its heavy taxes on
imported electronic equipment.
Anyone above the age of 12 can apply for a HAM license from the
Ministry of Communication. There
are four grades that an enthusiast can apply for directly, from
Restricted Grade II, Grade II, Grade I to
Advanced Grade, each with a respective examination. Higher grade
licenses allow the HAM more
freedom in using his/her equipment. The Advanced Grade exam
tests the user in basic electronics;
rules, regulations & procedures and Morse code sending &
receiving skills (A walk in the park for an
engineering student!).
By law, HAM radios can be used for personal communication
purposes only. It cannot be used for
commerce or broadcasting to the public (HAM signals are to be
received by other HAMs only). Using
modified HAMs; text messages, Amateur Television and data such
as photos can be sent around the
world at little or no cost.
A HAM can legally make his/her own HAM radio and develop ways to
make their equipment more
efficient. Some radios are also capable of satellite
communication with over 60 satellites servicing
HAM communication (Advanced grade is a prerequisite). HAMSAT is
ISRO's first theme based Micro-
satellite meant for providing Satellite based Amateur Radio
Services to the National as well as
International Community of Amateur Radio Operators (HAMs).
Every HAM all over the world is assigned a unique call sign by
the Ministry of Communication. This
sign is determined by the country the user belongs to.

There are many local HAM radio clubs located all over India.
Most clubs offer classes and study
material to aspiring HAMs and regularly hold events such as Fox
Hunt, a type of Treasure hunt that
requires the participants to use their radio communication
skills and equipment provided to them to
locate the target radio (Fox). These HAMs together form a large
community and annually organize
HAMfests.
If you want to start out, you can purchase study material, join
a course or just get in touch with a
friend who is a HAM.
Now, you really dont want to be left out while your 12 year old
annoying neighbour flaunts his
HAM; do you? Come join the fun, the HAM community is waiting to
hear your voice.
