An example of an amateur radio station with four transceivers, amplifiers, and a computer for logging and for digital modes. On the wall are examples of various awards, certificates, and a reception report card (QSL card) from a foreign amateur station.
Amateur radio, often called ham radio, is both a hobby and a service in which participants, called "hams", use various types of radio communications equipment to communicate with other radio amateurs for public services, recreation and self-training.[1] Amateur radio operation is licensed by an appropriate government entity (for example, by the Federal Communications Commission in the United States[2]) as coordinated through the International Telecommunication Union.[3]
An estimated two million people throughout the world are regularly involved with amateur radio.[4]
The term "amateur" does not imply a lack of skill or quality, but rather that the amateur radio operator is not paid for his or her efforts.
Main articles: History of amateur radio and Etymology of ham radio
Although its origins can be traced to the late 19th century, amateur radio, as practiced today, did not begin until the early 20th century. The first listing of amateur radio stations is contained in the First Annual Official Wireless Blue Book of the Wireless Association of America in 1909.[5] This first radio callbook lists wireless telegraph stations in
[edit] Activities and practices
Specialized Interests and modes
While many hams simply enjoy talking to friends, others pursue a wide variety of specialized interests.
Amateur Radio Direction Finding, also known as "Fox hunting"
Amateur radio emergency communications
Communicating via amateur satellites
Contesting, earning awards, and collecting QSL cards
Designing new antennas
DX communication to far away countries
Hamfests, club meetings and swap meets
Hand building homebrew amateur radio gear
High speed multimedia and TCP/IP
Portable, fixed, mobile and handheld operation
Tracking tactical information using the Automatic Packet Reporting System (APRS), which may integrate with the GPS
Using the Internet Radio Linking Project (IRLP) to connect radio repeaters via the Internet
VHF, UHF and microwave operation on amateur radio high bands
Vintage amateur radios, such as those using vacuum tube technology
Wireless MAN construction
Amateur radio operators use various modes of transmission to communicate. Voice transmissions are most common, with some, such as frequency modulation (FM) offering high quality audio, and others, such as single sideband (SSB) offering more reliable communications, often over long distance, when signals are marginal and bandwidth is restricted, at the sacrifice of audio quality.
Radiotelegraphy using Morse code (also known as "CW" from "continuous wave") is an activity dating to the earliest days of radio. It is the wireless extension of land line (wire based) telegraphy developed by Samuel Morse and was the predominant real time long-distance communication method of the 19th century. Though 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 theHAM RADIO
