A hamfest is a convention of amateur radio enthusiasts,[1] often combining a trade show, flea market, and various other activities of interest to amateur radio operators (hams).[2] In the United Kingdom the term rally is more commonly used for amateur radio conventions.[3] "Hamfests" were noted as early as 1924 in the U.S.[4]
