Have you ever wondered why radio amateurs are Called "HAMS"?

Well, it goes like this: The word "HAM" as applied in 1908 was the station Call of the first amateur wireless station operated by some amateurs of the Harvard Radio Club. They were Albert S. Hyman, Bob Almy, and Poogie Murray.

At first they called their station "HYMAN-ALMY-MURRAY". Tapping out such a long name in code soon became tiresome and called for a revision. They changed it to "HY-AL-MU", using the first two letters of each of their names. Early in 1910 some confusion resulted between signals from the amateur wireless station "HYALMU" and the Mexican ship "HYALMO". They then decided to use only the first letter of each name, and the station CALL became "HAM".

In the early pioneer days of unregulated radio, amateur operators picked their own frequencies and CALL-Letters. Then, as now, some amateurs had better signals than commercial stations. The resulting interference came to the attention of congressional committees in Washington and Congress gave much time to proposed legislation designed to critically limit amateur radio activity. In 1911, Albert Hyman chose the controversial Wireless Regulation Bill as the topic of his Thesis at Harvard. His instructor insisted that a copy be sent to Senator David I. Walsh, a member of one of the committees hearing the Bill. The Senator was so impressed with the Thesis that he asked Mr. Hyman to appear before the committee. Albert Hyman took the stand and described how the little station was built and almost cried when he told the crowded committee room that if the Bill went through, they would have to close down the station because they could not afford the license fees and all the other requirements which the Bill imposed on amateur stations.

Congressional debate began on the Wireless Regulation Bill and the little station "HAM" became the symbol for all the other tiny amateur stations in the country crying to be saved from the menace and greed of the big commercial stations who didn't want them around. The Bill finally got to the floor of Congress and every speaker talked about the " ... poor little station HAM". That's how it all started. You can find the whole story in the Congressional Record.

Nation-wide publicity associated station "HAM" with amateur radio operators. Since that time to this day, and probably until the end of time, a radio amateur is referred to as a "HAM"
