I'm curious as to why there is so much emphasis on electronics theory on the tests above the technician class? Is it just an artifact of the original testing process? I can't find a good corollary between my knowing more about electronics and being able to transmit on more frequencies. I have to believe that a great percentage of new HAMs will never open the case on their shiny, new, expensive radios and are more interested in the social aspect of the hobby than the electromechanical side. What do you think?
