ham radio
Licensed frequency hobby
Ham radio is amateur radio—two-way radio communication as a hobby rather than a profession or commercial service.
Ham operators obtain licenses, build or modify their own equipment, and communicate with others worldwide.
The term appears as both noun and adjective: a ham radio operator, talking on ham radio.
The origin of "ham" in this sense is unclear.
