An Introduction to Amateur Radio
What is Amateur Radio
Amateur radio is a community of people that use radio transmitters and receivers to communicate
with other Amateur radio operators.
If you were to ask a dozen different amateurs what ham radio meant to them chances are you would get 12 different answers. Amateur radio
operators are often called ham radio operators or simply "hams" and frequently the public is more familiar with this term than with
the
legal term Radio Amateur. The source of this nickname is for all practical purposes lost from the beginning.
Amateur (HAM) Radio is truly a hobby but often one that makes a difference especially in emergency or
disaster situations. It is an activity of Self Learning, Inter-Communication & Technical Investigation carried on between Amateur Radio
Operators. Amateurs talk to local friends over the radio waves using a hand-held transceiver, communicating digitally with packet
radio to exchange personal messages or vital information in an emergency, talking to other hams anywhere in the world, or engaging
in contests with other Radio Amateurs over the airwaves there is something for everyone.
There are over Lakh people all over the world who pursue this activity in their free time

What Hams do with amateur radio
- QRP - Communicating with "very low power" is a challenge that many hams enjoy. QRP is usually practiced on the HF bands
- HF radio - Hams can talk to other hams in literally any part of the globe using HF radios
- VHF (2 meters) or UHF (70 cm.) transceivers hams enjoy extremely reliable communications within their local community.
You can extend your VHF range up to 50 miles or more by transmitting through a local repeater.
- DXing. DX means distance communication and with the right equipment worldwide communication on the HF bands
(10 through 160 meters) is a regular possibility.
- Emergency and other volunteer services - Floods, landslides, earthquakes, Cyclones, Accidents (Rail / Road / Air).
when ever `normal' communications go out, hams are ready to use their radios to provide emergency communication services to their
communities
- Technical experimenting. Hams come from all walks of life ranging from technicians to engineers, teachers to scientists, and
students to retirees.
For many of them the attraction to the hobby is to build their own equipment whether it is just a simple antenna, something as complex
as a transmitter,
or an interface between their radio and a computer.
- Contesting. Contesting is often called the "sport" of ham radio. Almost every all the time there is some form of amateur radio
contest.
Hams get on the air and compete to see who can make the most contacts in a limited period of time.
- Talk to an astronaut. Yes, it is really possible. Space stations do have ham radio equipment and licensed ham astronauts take the
time to make contacts with amateurs on earth. Hams also have satellites where you can bounce a signal to communicate with other hams on
earth.
- Use digital communication. Connect a computer to your radio and install some software and you can be communicating digitally over
the air. Some of these digital modes can be more effective in marginal transmission conditions and some even sport error free
transmission.
- Internet communication. Using some of the latest technologies hams can supplement a modest station with Internet connections.
Using features such as URL or IRLP on a local repeater a ham in Toronto can talk to one in Vancouver or even Australia using a simple
hand-held transceiver
- Amateur television - It's just like real television because it is real television.
- Slow Scan TV - Send pictures around the world for little or no cost.
- Contests - You can put your radio operating skills up against other hams and teams of hams.
- Satellite communications - Hams operate using their own satellites for world wide communication using Walkie-Talkies.... They are
easy to use too.

How to Become a Radio Amateur
Amateur Radio Operators have to qualify in an examination conducted by Ministry of Communications, Government of India and obtain
license for operating / possessing a Radio Station.
Any individual above the age of 12 is permitted to appear for Amateur Station Operator License Examination and No Educational
qualification is prescribed.
It takes just two months (say two hours a day training) to become eligible for the examination. One should qualify a simple test
conducted in three subjects namely I) Morse Code (Transmission & Reception) ii) Communication Procedure iii) Basic Electronics.
The Officer-In-Charge, Wireless Monitoring Station, Dept. of Telecommunication under Ministry of Communication, Govt. of India is the
authority for conducting these tests in their own town provided there are sufficient number of applicants. The licenses are issued by
Wireless Planning & Co-ordination Wing of DOT, Govt. of India after passing the test in any of the following grades:
- Restricted Grade II -Permitting use of VHF/UHF only (i.e Walkie-Talkies).
- Grade II - Permitting HF/VHF/UHF frequencies but with limited transmitting power.
- Grade I- Permitting all amateur frequencies with higher power including latest techniques.
- Advance Grade- Permitting higher power and advanced techniques including Satellite Communication.
The Morse Code of 5 words per minutes sending-receiving will make eligible to get grade-II and 12 words per minutes sending-receiving
will get grade-I. For advanced grade higher level of technical knowledge in electronics is essentially required.
Basic knowledge can be obtained by purchasing study manuals, books on Morse Code from any of the amateur clubs.
- Local clubs - For those that like a structured approach, many clubs organize meetings and classes to teach the basic skills of radio
operation and prepare people for their ham radio license test. At the end of the classes, a test is given.
If you pass, you're a ham!
- You can do it by yourself. Many books for beginners are available. Some of them are below, for learning Morse code many software are available on this website.
- ABC
of Amateur Radio and Citizen Band (Rajesh Verma EFY Publications).
Once you are prepared, you can write examination, see Where to take Ham Radio License Examinations

Who issues Amateur Radio License in India?
Every licensed Radio Amateur is given a call sign that is used to identify you and your location of license. Each country that has
Amateur Radio status is allocated a range of call signs by the International Telecommunications Union (ITU). Amateur Radio License in
India are licensed by the Wireless Planning & Coordination wing of Ministry of Communications, Govt. of India and enjoy a far more
privileges of radio operation than "CB" radio operators do.
In many countries special call sign allocations may be made to commemorate a special event. These special event call signs
usually have an unusual prefix so that the station using the call will be easily recognized. For example the calls M2000A and 7S2000M
were heard quite often commemorating the year 2000. CI3O was used in 1996 for the Charles Island DX pedition. Many of these special
events also have unique QSL cards that are well worth the effort to make the contact and to send for the card.
With these privileges come responsibilities and rules for the operation of an amateur radio station. Specifically, there are a
few things that hams are not allowed to do:
- Hams are not allowed to do anything with their radios that makes them money in way. Ham radio is a hobby.
- Ham radio operator cannot `broadcast' to the public. This means that ham radio transmissions are meant to be received by other ham
radio operators. While a short-wave radios will allow you to listen to the ham radio bands, what you will hear is hams talking to other
hams and not music or other radio programs of `general' interest.
Within these (and other) guidelines, however, hams are empowered to do just about everything that government and private radio stations
are allowed to do.

Building Your First Radio
Amateur Radio Transceivers can be made by enthusiasts with locally available components. Several Hams have come up with their
circuit design, PCBs and construction of low cost amateur Radio equipment. Assume that you have just passed the Restricted Grade-II
class "no code" license and are looking for a first radio. Most Amateurs purchase a handheld VHF or UHF (or a combined "dual-band"
VHF+UHF) radio. You can optionally connect an external antenna at your home for extended range. A mere handheld, running low power, is
sufficient to gain access to most local repeaters so this is plenty to get you started.
There are several International brands that sell their Amateur Radio equipment in India with network chain of Dealers and sub-dealers.
You could buy any equipment that fits in your budget across the shelf from these dealers. The price of which can be obtained from them
