What is Ham Radio?

A housewife in North Carolina makes friends over the radio with another ham in Lithuania. An Ohio teenager uses his computer to upload a digital chess move to an orbiting space satellite, where it's retrieved by a fellow chess enthusiast in Japan. An aircraft engineer in Florida participating in a “DX contest” swaps his call sign and talks to hams in 100 different countries during a single weekend. In California, volunteers save lives as part of their involvement in an emergency response. And from his room in Chicago, a ham's pocket-sized hand-held radio allows him to talk to friends in the Carolinas.

Ham Radio, also known as Amateur Radio is a popular hobby and a service in which licensed participants operate communications equipment with a deep appreciation of the radio art.  The unique hobby of Amateur Radio is a mix of fun, public service, and convenience. Although hams get involved for many reasons, they all have in common a basic knowledge of radio technology and operating principles, and pass an examination for the FCC license to operate on radio frequencies known as the “Amateur Bands.” These bands are radio frequencies reserved by the Federal Communications Commission (FCC) for use by hams at intervals from just above the AM broadcast band all the way up into extremely high microwave frequencies.
