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. 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." 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.

The term "ham operator" was commonly applied by 19th century landline telegraphers to an operator with poor or "ham fisted" skills.

Early radio (initially known as wireless telegraphy) included many former wire telegraph operators, and within the new service "ham" was employed as a pejorative term by professional radiotelegraph operators to suggest that amateur enthusiasts were unskilled. In "Floods and Wireless" by Hanby Carver, from the August 1915 Technical World Magazine, the author noted "Then someone thought of the 'hams'. This is the name that the commercial wireless service has given to amateur operators..."

This pejorative usage continued into at least 1940, as evidenced in the January 1940 issue of The APCO Bulletin, where it was written "Rumors of citations by the FCC for violation of the superfluous traffic regulation on the part of certain of our radiotelegraph stations have resulted in a sudden decrease in 'hamming' on the police frequencies...".

Even among amateur radio operators, the term was used pejoratively at first by serious experimenters. For example, in December 1916 QST magazine, an amateur operator working on long distance message passing describes one way to avoid interference was to send messages "...on Thursday nights, when the children and spark coil 'hams' are tucked up in bed" (a spark coil was an unsophisticated radio transmitter, made from an automobile ignition coil, that produced noisy interference).

But only a few months later, in an indication of the changing use of the term among amateurs, a QST writer uses it in a clearly complimentary manner, saying that a particular 16-year-old amateur operator "...is the equal of a ham gaining five years of experience by hard luck."
