As with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. Amateur radio enthusiasts have significantly contributed to science , engineering , industry , and social services.

Research by amateur operators has founded new industries, [4] built economies, [5] empowered nations, [6] and saved lives in times of emergency. The use of "ham" meaning "amateurish or unskilled" survives today in other disciplines "ham actor". The amateur radio community subsequently began to reclaim the word as a label of pride, [14] and by the midth century it had lost its pejorative meaning. Although not an acronym, it is often mistakenly written as "HAM" in capital letters.

Activities and practices[ edit ] The many facets of amateur radio attract practitioners with a wide range of interests.

Many amateurs begin with a fascination of radio communication and then combine other personal interests to make pursuit of the hobby rewarding. Some of the focal areas amateurs pursue include radio contesting , radio propagation study, public service communication , technical experimentation , and computer networking.

Amateur radio operators use various modes of transmission to communicate. The two most common modes for voice transmissions are frequency modulation FM and single sideband SSB.

FM offers high quality audio signals, while SSB is better at long distance communication when bandwidth is restricted. Although computer-based digital modes and methods have largely replaced CW for commercial and military applications, many amateur radio operators still enjoy using the CW mode—particularly on the shortwave bands and for experimental work, such as earth-moon-earth communication , because of its inherent signal-to-noise ratio advantages.

Morse, using internationally agreed message encodings such as the Q code , enables communication between amateurs who speak different languages.

It is also popular with homebrewers and in particular with "QRP" or very-low-power enthusiasts, as CW-only transmitters are simpler to construct, and the human ear-brain signal processing system can pull weak CW signals out of the noise where voice signals would be totally inaudible.

A similar "legacy" mode popular with home constructors is amplitude modulation AM , pursued by many vintage amateur radio enthusiasts and aficionados of vacuum tube technology.

Following changes in international regulations in , countries are no longer required to demand proficiency. Specialized digital modes such as PSK31 allow real-time, low-power communications on the shortwave bands.

EchoLink using Voice over IP technology has enabled amateurs to communicate through local Internet-connected repeaters and radio nodes, [20] while IRLP has allowed the linking of repeaters to provide greater coverage area.

Automatic link establishment ALE has enabled continuous amateur radio networks to operate on the high frequency bands with global coverage. Other modes, such as FSK using software such as WSJT , are used for weak signal modes including meteor scatter and moonbounce communications.

Fast scan amateur television has gained popularity as hobbyists adapt inexpensive consumer video electronics like camcorders and video cards in PCs. Linked repeater systems, however, can allow transmissions of VHF and higher frequencies across hundreds of miles.

Repeaters can also be linked together by using other amateur radio bands , landline , or the Internet. NASA astronaut Col. Amateur radio satellites can be accessed, some using a hand-held transceiver HT , even, at times, using the factory "rubber duck" antenna. Some join in regularly scheduled on-air meetings with other amateur radio operators, called " nets " as in "networks" , which are moderated by a station referred to as "Net Control".

Amateur radio operators, using battery- or generator-powered equipment, often provide essential communications services when regular channels are unavailable due to natural disaster or other disruptive events.

Related Interests

Many amateur radio operators participate in radio contests, during which an individual or team of operators typically seek to contact and exchange information with as many other amateur radio stations as possible in a given period of time.However, the "Save radials" option, although present, may be greyed out and cannot be selected.
