It
is an undeniable maxim that when a field of study is adopted by hobbyists, the rate of progress accelerates significantly.
Not many examples are as obvious as with amateur radio (Ham) enthusiasts. I have had the honor of working with many
top-notch engineers and technicians in my nearly 30 years in electronics, and without a doubt, a lot of the very best
were Hams. That is not to say there are not any top-notch electrical engineers that do not indulge in the hobby, there
are. The difference is that the Ham radio guys typically exhibit an enthusiasm that is not so overtly apparent in
the non-Hams. Where the Amateur radio folks typically shine is when they are in positions that do not normally require
a talent for RF knowledge. Whether that be as a project manager, a mechanical engineer, or software guy, one more
than one occasion I have seen one of them throw out an idea during a brainstorming session that saved the moment.
My hat is off to them.
