What is it with HAM? I don’t know where it came from or why some people use the expression HAM instead of ham or ham radio. HAM is obviously an acronym for something. Maybe Hairy American Magician? I have heard people say they “have been involved in ham” for three years. Not ham radio. But ham. Apparently they are not vegetarian. Did the English language leap through some sort of discontinuity or did I just miss the transition? I missed the one where “who” turned into “that” so maybe I missed another one. And where does “shack” come from? Does it not predate Radio Shack? Are we shacked up with our radio stuff? Or are our radio rooms descended from small rundown buildings? Or from wooden sheds housing spark gap transmitters?
