THEORY 4
Another theory attributes the term "HAM" to: Hugo Gernsback, publisher of a magazine called "Home Amateur Mechanic" which was very, very popular back in the early days of radio. It was so well know, it was a household word, just as the magazines "People", or "Reader’s Digest" are today. Although it was primarily more mechanical in content, it did contain fairly regularly, Amateur Radio construction projects. Thus, when asked what sort of radio a person had, the reply, more often than not, was he: "had one of those "H.A.M." (using just the initials of the well known magazine name.) This theory becomes a bit more believable when you consider the Amateur Radio practice of using just initials or letters for many commonly understood words in order to shorten transmissions and ease sending of messages, especially when using Morse Code. "Home Amateur Mechanic" was simply shortened to H.A.M.
Theory 5
Some speculate the term "HAM" stands for "Help All Mankind" as reflected in the radio amateur’s long history of service towards people in distress during natural calamities, disasters and civil emergencies. In fine S.O.S. tradition, this gives us H.A.M.
Theory 6
Others believe the term "HAM" derives it’s origin from the British. From late in the nineteenth century forward, British sports writers used the "AM" to describe rank AMateurs in sports. It first came into the "electronics arena" from the "wire telegraphers" used by these sports writers. The telegraph operators originally applied it to the younger and inexperienced "cub" reporters. These young sports writers often provided illegibly written or poorly worded copy for the telegrapher to transmit. The professional news telegraphers had beginners in their own line of work, and they picked up the 'AM terminology from the sportswriters, and applied it to their own field. Often the inexperienced new telegraph operators were called "AMs", for the amateurish way they sent messages.
Theory 7
This theory holds that the term "HAM" actually derives from what the seasoned commercial (professional) telegraph operators called the (hobby) amateur radio operators. When the inexperienced hobby radio enthusiasts began to venture on air with crude spark-gap transmitters, based on vehicle ignition coils, their code transmissions must have been pretty poor compared to the commercial telegraphs of the day. The commercial operators referred to the amateurs by using a modification of the old telegrapher's insult (from above) by saying the operator was "ham fisted", meaning that they weren't of professional skill. "Ham Fisted" referred to their style and proficiency of sending telegraph code which could have been done just as well by using a ham (the cut of pork) on the telegraph key to pound out their rudimentary code.
Theory 8
Along those same lines of thought, came this theory linked to the stage and theater, where the term "HAM" is used to denote an actor of indifferent ability, or one who shows off his skill (or lack thereof), by performing in spite of and mostly oblivious to his own ineptitude.
Theory 9
This following theory seems to combine the "ham fisted" and the "un-professional operator" theories from above, but also adds a bit more insight as to why amateur radio operators might be called "HAMS": Definition of HAM: "A poor performer. [in this case:] "An operator of poor performance and courtesy". Even before wireless radio, that's the gist of a definition of the word "Ham" given in the G. M. Dodge book: "The Telegraph Instructor." The definition never changed throughout wire telegraphy history. The first WIRELESS operators were, of course, originally land based (wire) telegraphers, who left their offices to go to sea or to man the coastal stations. They brought with them to their now jobs their old habits, both good and bad. Along with them came also slang terms, operating practices, and much of the tradition of their older profession.
