![]() ![]() All panels and chassis holes are drilled using computer coordinates on a mill. All my sets are fully designed first on paper, then in a computerized drawing (CAD) program. I enjoy making these little radios and I usually spend several times as long in the design and layout stages as I do actually constructing the sets. This page is arranged with my latest Crystal Radios at the top, and working down through time to my first radios. More information about crystal sets appears at the bottom of this page. Since then, both in business and as a radio amateur, I have designed and built a multitude of receivers, transmitters, and other electronic equipment, but I never forgot my early fascination with the crystal set. It worked swell, but the filaments all fell out of the tubes after about 5 miles on that rough scooter. I even made a special five-tube radio designed to mount in the steering column of a 60 Series scooter.
