Dear reader, as I've written above that I love writing but these days I'm too much busy preparing for A.S.O.C examination. Amateur Station Operators' Certificate examination is the first step towards become a HAM. Sometimes it is hard to see people around us know nothing about this hobby, for example one of my colleagues patted me on my back saying it will be nice to hear me as RJ on air, oops!
Ham radio is just a serious hobby and hams do not get a single penny out of it, if you want to listen to them you need to become a short wave listener or a ham. People interested in radio communication technology, electronics circuitry, DX-pedition, CW communication, helping people during emergency etc. take ham radio as their hobby, hams frequently check-into nets and discuss on various topics. I became interested in ham radio during my college days when I was a student of communication engineering.
EM and Antenna theory were two of my most favorite subjects as an UG student in B.I.E.T; my score card did not reflect that, though. Some people say antennas are very mysterious things that human ever built, antenna is our another eye to see a different world which is not visible through ordinary eyes, it is a tool to create disturbances in cosmic ocean and we use antenna to hear them too. At AT&T Bell Labs in New Jersey, a young radio engineer named Karl Jansky (Father of Radio Astronomy) discovered radio frequency emission from the center of our milky way galaxy on 1933, the signal is strongest in the constellation of Sagittarius. Now the science community has a map of such invisible (no visible light wave emission but radio waves) quasars and pulsars. Our own Sun is a rich source of radio and microwave (Screams from the Sun?). Radio astronomy and amateur radio have close relations between them since beginning.
I've seen hams who are just interested to communicate people far away with their home-brewed radio communication apparatus just to see how minimal power consumption could be possible to make such communications; they work on different types of antenna, use different modulation techniques, tactically use ionosphere or the moon as reflector, track satellites and make satellite communications etc.
Indian hams are always active in relief and disaster management activities, some of their recent relief works are reported below. If you are also interested in ham radio ham community is always there to help you. But don't be afraid of learning Morse Code, it is old but gold (winking).
The Telegraph: Radio hams to rescue.
The Times of India: HAM radio team tunes into relief work.
The Times of India: Relief workers bogged down by fatigue.
The Times of India: Radio stations turn watch towers.
The Hindu: Centre acknowledges HAM role in tsunami relief.
