Many years ago a fellow ham said, "You should be able to do that (some design function I cannot remember) because you are an engineer. I replied, " I would not be an engineer if I was not a ham!" I learned most of my real microwave design techniques as a ham in the 1950s and 1960s. I was able to use those techniques as an engineer in the 1960s, 70s, 80s and 90s. To me hamming and engineering were synonymous.
