Glossary of Common Ham Radio Terms Amateur Radio. HamRadioTerms-2011. Etymology of ham radio. Ham radio is a popular term for amateur radio, derived from "ham" as an informal name for an amateur radio operator.

Etymology of ham radio

The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A. Morton reported overhearing an amateur radio transmission which included the comment: "Say, do you know the fellow who is putting up a new station out your way? I think he is a ham. "[1] However, the term did not gain widespread usage in the United States until around 1920, after which it slowly spread to other English-speaking countries. The term amateur in amateur radio is used to distinguish it from commercial pursuits, as radio amateurs are prohibited by law from accepting monetary or material compensation of any kind for any activities they perform as radio operators.

Etymology[edit] The term "ham operator" was commonly applied by 19th century landline telegraphers to an operator with poor or "ham fisted" skills.[2][3][4][5]
