> I clearly remember the prof saying "oh, you're one of those hobbyists" I have a very different, and more pleasant, memory of walking into a 3rd-year Electromagnetic Fields class that had some stuff on the board leftover from a senior-year "Microwaves and Radar" class. Prof said, "half a point on the midterm to anyone who knows what that diagram is." I glanced up, said, "Smith chart" and went back to getting my assignment out. He stared at me in surprise and said "Oh, we have a ham in the room!" Don't remember if I ever got my 0.5 point increase though. I do remember barely passing that class!
