They have come a long way from the hand wound coil and a cats whisker

I built one of those things once but never did get it to work. A
germanium diode was just a whole lot better. The hand wound coil was
OK however. A few years later I added a one transistor audio amp and
that was a whole quantum jump in performance. It also looked kind of
cool beng built on a small piece of 2x4 lumber, using nails and screws
for junction points. The battery holder was made from tin strips cut
from a can. A friend of mine asked to borrow it and next thing I knew
he had won the science fair with it. Should have ratted him out but
I didn't.
