What is Amateur Radio?
Amateur Radio, or Ham Radio, is a hobby with activities involving communication via radio waves. Most enthusiasts are fascinated with operating radio transmitters, receivers and antennas or how radio waves are able to get from one corner of the earth to another.
How is Amateur Radio fun?
The fun comes from various activities:
DXing: This is making long Distance radio contacts via Morse Code, Voice or Digital Modulation with another ham radio station in a another country thousands of kilometers away with just your radio transmitter, an antenna, and radio waves. There are over 300 countries for you to 'work'. Some countries are extremely difficult to make contact with because there aren't any hams there. LISTEN to Nan 9V1AC in Singapore "working" with a ham in the Netherlands.
Satellite Communications: This is like DXiing except that dedicated Radio Amateur Satellites in a low space orbits are used to relay the signals. WATCH a ham in eastern Java, Indonesia work Siva 9V1SV in Singapore by using a handie-talkie and a homebuilt high-gain antenna
Collecting and Exchanging QSL cards: Just as there are Stamp and Coin Collectors, there are Hams who collect and exchange QSL cards. A QSL card is a personalized card which hams exchange to show legal proof that a radio contact did happen. When a ham has proof that he has 'worked' 100 different countries, he can apply for the prestigious DXCC award.
Rag Chewing: Just simply having chat through the radio with a Ham in Singapore, or with another Ham in Japan can be quite interesting. You may both be old acquaintances or more often, be meeting on the air for the first time. You can talk about anything decent under the sun, except business, politics and religion.
Projects: Many hams build electronic projects and write software (coding) for their devices. We experiment with building transmitters, receivers, RF amplifiers, antennas, decoders, test equipment and Software defined radios within the limits of our license priviledges. Quite often, radios are interfaced with the PC for Communication modes like PSK31, D-STAR and Packet Radio.
Contesting: There are various contests conducted regularly by the various ham organizations around the world. Each contest has a theme, for example, in the 'CQ Worldwide' contest, participants try to 'work' as many stations as possible in a 48 hour weekend period. Points are scored depending on the region worked.
DXpeditions: Imagine 6 hams from various countries, with 1850 kg of radio equipment, personal stuff and food, sailing on a ship for 2 weeks, to a remote island, with a difficult-to-pronounce-name in the South Atlantic Ocean, brazing sub-zero temperatures for 6 days, working in shifts to make radio contact with other hams around the world. This IS extreme fun! Watch the 1997 BS7H dxpedition
