Amateur radio has always been at the forefront of communication research, so the nickname for amateur radio honors three men who themselves were at the forefront: Heinrich Hertz, who studied electromagnetic waves and for whom the unit of frequency is named; Edwin Armstrong, who invented among other things the superheterodyne receiver and frequency modulation; and Guglielmo Marconi, the first to transmit information by radio wave.

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 service, recreation and self-training.[1] Amateur radio operators enjoy personal (and often worldwide) wireless communications with each other and are able to support their communities with emergency and disaster communications if necessary, while increasing their personal knowledge of electronics and radio theory.
