FASCINATING WORLD - AMATEUR RADIO - Amateur Radio scientific hobby Self training, technical investigation world wide Radio communication carried out duly authorised Persons without pecuniary interest. Amateur Radio International hobby. Amateur Radio operator called HAM or Radio Amateur. HAM stands first letter 3 pioneers field Radio communication viz., Hertz Armstrong Marconi. This is hobby that requires licence concerned authorities their respective Government. HAMs use transceivers communication (Transmitter and Receiver). not surprised know that, every minute day there hundred hundreds Amateur Radio operators operating their equipment around world. can make global friends, exchange views, ideas, explore the culture, lifestyles HAM friends. can utilise his/her free time creatively Amateur Radio. doesn't feel lonely even if nobody home, if he or she HAM, the world comes into confines their room anywhere anytime. After getting licence going `ON AIR' find people different walks life, people electronics, computers, space, medicine, farming, film industry, students, teachers, VIPs few name. Imagine HAMs playing chess sitting their rooms across continents !! There about 10,000 HAMs India, out which only few thousands active on air. scene different countries Japan, USA etc., which millions active Radio Amateurs. After getting licence Ministry Communications going on air privilege making friends all round globe. It's whole special way making friends. real thrill Amateur Radio while making contacts across oceans, across seas one's own home made equipment, even though one can get imported multi-band all-mode transceiver. can make or get assembled transceivers much less price than imported ones, yes but less features. can start hobby with ordinary broadcast receiver ( 2 or 3 band Transistor Radio) then after getting licence, he or she can on AIR low power SET-UP costing just around Rs. 1,500/= or else should member Amateur Radio Club. HAM Radio used self training investigation in field electronic communications carried out licensed persons. HAM Radio provides opportunity serve country, people above all HUMAN MANKIND. During natural calamities earth quakes, floods etc., service rendered HAMs recognised appreciated. HAM can serve society ways making available difficult-to-get life-saving drugs part world through HAM Radio time. During AMARNATH YATRA `96 disaster, HAMs all over country maintained emergency network linked Srinagar to relay messages relatives people trapped on way. lives been saved high seas, of sailors on board where HAMs. pilot (HAM ) saved lives people on a passenger airliner which lost Radio contact ATC (Air Traffic Control ) , HAM he gave distress call ( SOS ) on HAM Radio flight above Indian Ocean help HAM south India picked signal got touch ATC via Telephone, helped perfect landing aeroplane. TYPES LICENCES India, there five grades Amateur Wireless Telegraph Licence ( AW/T):- 1. Short Wave Listeners Licence. 2. Restricted Grade. 3. Grade II. 4. Grade I. 5. Advanced Grade. minimum age getting Licence 12 years age India. Licence fee Advanced Grade , Grade I, Grade II / Restricted/SWL Rs. 50/= , Rs.40/=, Rs.25/= respectively period two Years. Exams :- obtain AW/T licence appear ASOC examination (Amateur Station Operators Certificate) conducted Wireless Planning Co-ordination Wing Ministry Communications. exam conducted monthly big cities once two months places. ASOC exam two parts ; Part - I : a) Basic Electronics (Radio Theory Practice) b) Rules Regulations (Indian International Radio rules regulations ) Part - II: a) Morse code receiving b) Morse code sending Grade II exam 5 words per minute test 12 words per minute Grade I Advanced Grade. Restricted Grade there no Morse code test ( but can't enjoy full fruit HAM Radio), only point to point communication Licence. examination NOT DIFFICULT pass. Do know 7 year old USA got Amateur Wireless Licence. MORSE CODE : - Morse Code International Language. Since HAMs come every nook corner globe there may language barriers but Morse Code Builds bridges friendship. Morse Transmission considered efficient means communication adverse Band (radio frequency) conditions. Now other digital modes have come which efficient or even more than Morse transmission. On economical grounds most Indian HAMs cannot afford costly means equipment's enjoy full fruit Amateur Radio. Once learns Morse operate, just hearing music on air!!. can convey messages end much faster than talking. There special abbreviations Amateur Radio that helps sending messages quickly over radio known "Q"codes. example if sends following Morse code :- QRV? This means `are ready receive my signals ?' QRV This answer that `I am ready receive your signals' Notice speed which can communicate. is only practice gains speed. Books related Amateur Radio available leading book shops Viz., `ABC Amateur Radio India'. study Morse just takes a matter two weeks really interested person or takes time he or she wishes. After gets through exam he or she wait for decision Ministry grant AW/T licence, that takes matter few months. different modes used Amateur Radio operators are :- Morse, Voice, SSTV (SLOW SCAN TV),FSTV (Fast Scan TV), RTTY(Radio Teletype), Packet Radio, AMTOR ( Amateur Teleprinting Over Radio), PACTOR ( Packet Teleprinting Over Radio). There Amateur Satellites orbiting very thrilling experience have conversation sitting one's room Robot on board. All SPACE missions so far had atleast HAM Radio Operator (Astronaut) on board. Sitting your SHACK ( Radio Room) can contact Astronaut and talk SPACE. satellites have ( HAM ) Robots which respond the call reply back !! RADIO SYSTEM Basic requirement AW/T station transmitter / receiver . transmitter used send Radio Waves. Picks Voice and converts radio frequency using Antenna radiates signals. On the hand receiving end antenna traps signals reproduces signal into meaningful information ( Intelligence ). There various modes which signals send, Voice, Morse, Digital Data ( Packets) etc., Amateur Radio various frequency bands allotted by International Telecommunications Union on 3.5 3.7 MHz, 7- 7.1 MHz, 14 - 14.350 MHz, 21- 21.450 MHz etc., Even using ordinary Broadcast receiver one's home good external antenna, can hear Amateur Radio Operators conversing on air. STATION IDENTIFICATION :- Amateur Radio Station identified its Call Sign case telephone telephone number. ISD dial code 91 represents India, VU represents India followed digit 2,3,4,7 etc., followed again 2 or 3 characters which identifies station. So typical Indian station have Call Sign VU2UKR or VU3CYL or VU2AWC etc., Call Signs Sri Lankan stations starts the prefix 4S7, Pakistan AP2, Russia RA6, Japan JA3, Germany DL4, USA KC4 etc., ESTABLISHING CONTACT First tune Transceiver , if happens hear some station wish contact, give "break in" call. Once station replies back call exchange signal report, chat goes on ...... . way tune clear frequency give a general call on air. When HAM hears, he/she replies back. way give directional call (a call stations particular Continent or Country). HAMs all equal, there no `SIR' or `Mr'. or `Mrs' even if person 7 years old or 70 years old , male referred `OLD MAN' similarly female `YOUNG LADY'. Amateurs forbidden transmit messages related Business, Religious, Political, or matters which can cause communal problems, or matters which can deprive Government its revenue etc., NET "NET" conducted around country, meaning National Emergency Traffic. NETs conducted daily on different bands fixed timings frequencies. during day during night. On NET, net controller (HAM) conducts NET day, he calls `check-ins' NET. Stations on NET frequency give their call signs wait there turn stay on frequency duration NET. After checking in, station stays back on frequency listening NET emergency or medical traffic. If HAM station requires medical help / emergency he contacts NET controller turn NET controller announces over the band, seeks help station on frequency meet emergency handled a very professional way. Life saving medicines time emergency or alert of distress, or weather forecast, band condition, or needs handled on NET. Usually on NET when `traffic or emergency communication' less then HAMs use NET typical telephone exchange getting HAMs connected allotting different frequencies group HAMs their round table discussion on air. Usually HAMs talk more about technical aspect of radio communications, interested making friends around globe, look their counterparts having same profession. HAMs contact HAMs (doctors) when they sick home, get their diagnostics done while lying there bed over radio ! QSLs This yet another Q Code meaning `can acknowledge receipt'. Once establish two way Radio contact another station, a special post card exchanged Viz. QSL card. This card Call Sign of Station worked, date, time, frequency, signal report, his or her equipment details station, country, place information's of interest. If happens collect 100 QSL Cards different countries listed AMERICAN RADIO RELAY LEAGUE get prestigious award called "The DXCC". DX means Distant or Unknown, CC the Centenary Club. station outside India DX country Indians. FIELD DAY Field Day word itself sound, day(s) field. actually exercise conducted group HAMs SWLs go place interest, say example high on Mountain terrain's, deep jungle Set-up Amateur Radio Station maintain Radio Network awareness program meeting emergency communication requirements during calamities. During Field Day areas study mainly Propagation Conditions, Sunspot Activity, Radio Astronomy, Sporadic Propagation, Location putting Antenna, choice type Antenna, Direction, Tuning RIG ( HAM equipment) last establishing contact. So Field Day, SWLs people have interest in Radio Communication learn lot Radio Amateurs, ways put a station, procedures establishing contacts on network etc., also serves opportunity HAMs SWLs meet their HAM friends person. Though great friends over Radio, a crazy occasion when meets him/her person, configuration mind does not resemble actual !! can study basic necessities setting an Amateur Radio Station case emergencies, adverse situations or difficult places unfavourable putting station get on new ideas. EXPEDITIONS:- Popularly known DX-pedition. So Field Day here group people venture out Sea island, places Viz. Antarctica, Arctic, Bering islands etc., venture out expedition SAMUNDRA IV Yatch expedition "BALI YATRA" Indonesia. Expeditions Lakshadeep and Andaman Islands Popular around world. Expedition Team gets world attention millions millions HAMs looking out DX-pedition Stations because usually have different CALL SIGN (special one) that, who contacts station island really thrilled have worked that part the world which usually rare. India VU7 prefix given DX-pedition Teams to Lakshadeep Andamans than usual VU2 VU3 prefix on main land. FOX HUNT really fun, hunting FOX !!! FOX Radio Transmitter hidden place the city or town or forest or where ever might be, sometimes can't imagine even if well. would transmit Radio Signals intervals time. The participants Fox Hunt locate hidden transmitter which may within range say 15 20 Kms. pair team, usually equipped transceiver (hand held), Beam Antenna connected it. mount on top their vehicles hold their arms while using two wheeler. So can find crazy people carrying Beam Antenna their hand while on road, referring maps, using direction finder locate hidden fox. team which finds fox rewarded. AMATEUR SATELLITES There Amateur Satellites or simply satellites carrying Amateur Radio on board. These Satellite Radio Amateur Stations Microprocessor controlled. Signals beamed orbiting satellite get the acknowledgement. Mostly communications short duration, exchange of signal reports, location etc., satellites used repeater station, station UPLINKS signal satellite signal retransmitted [ DOWNLINKS ] ground covering large area [ Foot Print ] on another frequency.

A new problem is the attempt by some companies to transmit the Internet over powerlines. Known as BPL, this technology can create significant radio static. While the U.S. Federal Communications Commission appears to be sympathetic to the industry, amateurs have been battling it. To date (2005) field trials by the industry have generally been unsuccessful in meeting radio pollution standards, and often discontinued after brief attempts to attract customers. The technology also been under severe criticism in Europe. Given other transmission modes, the future of BPL appears very questionable.
According to the Federal Communications Commission, the agency that regulates radio and telecommunications in the United States, amateur radio serves the following purposes:
Amateur radio and innovation in telecommunications technology
Amateur radio on the screen
Amateur radio represents a unique research and development (R&D) environment that cannot be duplicated in the labs or research parks of either industry or the government. Existing at the intersection of the social, economic, cultural and scientific spheres, amateur radio leverages this position to invent and innovate from a unique perspective. Many now-commonplace communication technologies have their genesis in amateur radio.
Amateur radio, commonly called "ham radio", is a hobby enjoyed by many people throughout the world (as of 2004 about 3 million worldwide, 70,000 in Germany, 5,000 in Norway, 57,000 in Canada, and 700,000 in the USA). A holder of Amateur Radio licence studied and passed required tests in his or her country and been issued a call sign by its government. This call sign is unique to the operator and is often a source of pride. The holder of a call sign uses it on the air to legally identify all voice and data communications. Amateur Radio should not be confused with CB radio, General Mobile Radio Service or Family Radio Service, which are limited to voice operation only, lower power limits, fewer frequency allocations, and are unlicensed in most countries.

Contesting is another activity that garnered interest in the ham community. During a period of time (normally 24 to 48 hours) a ham tries to successfully communicate with as many other hams as possible. In the U.S., one such event is Field Day, held in the fourth full weekend in June. The contesting amateur may concentrate on just DX stations, or only on stations powered by emergency generation equipment or running on batteries, which is meant to simulate hurricane or other emergency disaster conditions. Some contests may or may not be limited in allowable modes of transmission, such as voice or Morse.
Despite all these exciting specialties, many hams enjoy the informal contacts, long discussions or "rag-chews", or round table "nets", whether by voice transmission (SSB, AM, or FM), CW (morse telegraphy), or one of the digital modes (RTTY, PSK31, and others).
Even with the advent of the Internet (offering email, music, broadcast audio, video, voice over IP (VoIP)) ham radio is not diminishing in countries with advanced communications infrastructure. Amateur radio remains strong even today, as figures from the American Radio Relay League will prove. This may be partly because Hams enjoy communicating using the most minimalist simple hardware possible as well as finding the most technically advanced way, advancing the art of radio communication at both ends, frequently beyond what professionals are willing to try and risk.

Many of these rely on the "simplex" mode, that is direct, radio-to-radio, avoiding the problems associated with networks that might fail. In Ham Radio simplex communications would allow skilled radio operators to talk across town on VHF or UHF frequencies, or across the world on the HF (shortwave) bands of frequencies. Hams also have another powerful tool available, repeaters. Repeaters are radio relay devices usually located on the top of a mountain or tall building. A repeater allows the licensed Ham to have radio coverage for hundreds of miles from just a small handheld or mobile two-way radio.

Hollywood movies have also used Amateur Radio as a convenient and often fanciful part of their plot:
However, the amateur radio service, or more specifically, the portion of the electromagnetic spectrum allocated to the activity, is under extreme pressure from the telecommunications industry. Recent exponential growth in commercial wireless communication systems taxed existing commercial spectrum allocations, and industry is eager for expansion. Amateur radio spectrum is threatened. Ironically, many of the communication technologies used by these firms were initially developed within the field of amateur radio.
In times of crisis and natural disasters, ham radio may be the only surviving means of communication. It been found all too often that both wire and cellular telephone systems either fail or are overloaded in times of crisis and radios dedicated to emergency services fare little better. In the United States, two organizations of amateur radio operators exist nationally for disaster communications. They are the Amateur Radio Emergency Service (ARES) and the Radio Amateur Civil Emergency Service (RACES). Typically a local radio club will have information on joining either or both. In areas where known disaster problems exist, amateur radio a long-standing tradition of cooperation with local emergency services.

Licensed Amateur Radio operators enjoy personal two-way communications with friends, family members, and complete strangers, all of whom must also be licensed. They support the larger public community with emergency and disaster communications. Increasing a person's knowledge of electronics and radio theory as well as radio contesting are also popular aspects of this radio service. A good way to get started in Ham Radio is to find a club in your area to answer your questions and provide information on getting licensed and then getting on the air!
Licensed amateurs often take portable equipment with them when travelling, whether in their luggage or fitted into their cruising yachts, caravans, or other vehicles. On long-distance expeditions and adventures such equipment allows them to stay in touch with other amateurs, reporting progress, arrival and sometimes exchanging safety messages along the way. Many static-based hams are very pleased to hear directly from such travellers. From in a yacht in mid-ocean or a 4x4 inside the Arctic Circle, a friendly voice and the chance of a kind fellow-enthusiast sending e-mail home is very well received.
Major clubs, societies, and associations
Many countries have their own national (non-government) Amateur Radio society that coordinates with the communications regulation authority for the benefit of all Amateurs. The oldest of these societies is the Wireless Institute of Australia (WIA), formed in 1910; other notable early societies are the Radio Society of Great Britain founded in 1913 the American Radio Relay League created in 1914 and Radio Amateurs of Canada. National societies also cooperate through the International Amateur Radio Union (IARU).
Many other awards are also available. Some, such as working 100 islands, including at least one from every continent, or contacting the 40 radio "zones" that the world is unofficially divided into, are fairly difficult. While working every U.S. state can be done in a few months of casual operation, confirming every county can take a decade or more. Others awards, such as contacting all 10 U.S. radio districts, are quite easy. In addition, every year there are many special event stations on the air. Set up to commemorate special occurrences, they often issue distinctive QSLs or certificates. Some use unusual prefixes, such as the call signs with "96" that Georgians could use during the 1996 Atlanta Olympics. (Collecting prefixes is another aspect of the hobby.) Many amateurs decorate their radio "shacks" with these certificates. Not surprisingly, they are called "wallpaper."

More recently, on September 2, 2004, ham radio was used to inform weather forcasters with information on hurricane Frances live from the Bahamas. On December 26, 2004 a great tsunami across the Indian Ocean wiped out all communications with the Andaman Islands, except for a DXpedition that provided a critical link with the outside world to coordinate relief efforts.

On March 18, 1909, Einar Dessau used a short-wave radio transmitter which made him the first to broadcast as a ham radio operator.
One of the many exciting activities of ham radio is the DX-pedition. Radio amateurs collect QSL cards from other stations, indicating the continents and regions which they have contacted. Certain zones of the world have very few radio amateurs. As a result, when a station with a rare ID comes on the air, radio amateurs flock to communicate with it. To take advantage of this phenomenon, groups of hams transport radio equipment into a remote country or island (such as normally uninhabited Bouvet Island, which the rare callsign prefix 3Y). These expeditions can help hams quickly achieve a communication award such as a DXCC. To obtain the DXCC award a ham needs confirming QSL cards from hams in 100 countries around the world.

Some hams use VHF or UHF frequencies to bounce their signals off the moon. The return signal is heard by many other hams who also do EME (earth-moon-earth). The antenna arrays are massive so a lot of real estate is needed. Other hams transmit with very low power. Signals on the order of 5 watts or less are heard all over the world by these QRP (low power) operators.
The International Telecommunication Union (ITU) governs the allocation of communications frequencies world-wide, with participation by each nation by representation from their communications regulation authority. IARU member nations may choose to further limit specific frequency allocations within IARU guidelines.
Through ITU agreement bandwidth been set aside for amateur transmissions. Amateurs use a variety of transmission modes, including Morse code, radio teletype, data, and voice. Specific frequency allocations are a matter of record and vary from country to country and region to region, but the frequency allocations in the USA are:
Throughout its history, amateur radio made significant contributions to science, industry, and the social services. The economic and social benefit derived from amateur radio research founded new industries, built economies, empowered nations, and saved lives.
To justify their quest for additional spectrum, industry lobbyists portray amateur radio as anachronism, and characterize amateur bands, particularly in the UHF and microwave region, as underutilized. On the contrary, innovative communications research within the hobby is alive and well, and many of these new amateur projects utilize the higher-frequency bands sought after by industry. There is commercial interest in some of the new technologies currently under development within amateur radio, and amateur radio continues to contribute to the state of the radio art.
Tony Hancock's 1960 BBC TV episode "The Radio Ham", in which he plays incompetent ham radio operator, remained popular in the U.K. and played a small part in keeping the memory of ham radio's heyday alive.

Use and available activities
utilizes VoIP to tie repeaters together directly by user command. This nascent use is finding applications in emergency services as well, as alternative to expensive (and sometime fallible) trunking systems.
Voice over IP (VoIP) is also finding its way into Amateur Radio. Programs like Echolink tie hams with computers into ham radio repeaters across the globe. The Internet Radio Linking Project (IRLP) HAM Amateur Radio
