In this review, we look, however briefly, at some of the highlights in the nearly 70 years of amateur radio, from sparks and coherers to sophisticated solid-state transceivers. We believe that this record testifies to the worth of the amateur approach in almost every phase of the radio communications art. If we have coped with the rush of technology and kept our enthusiasm thus far hopefully, ham radio operators of the future will be able to carry on this tradition.
