As a teenager I recall the war news about a radio
which used a blue blade and a small pointed wire
for a detector.  An Anzio Radio, they called it.
I can understand the razor blades being made
available, but I can't figure where the headsets
came from.  Maybe a EE-8.  In about 1938 I
saw a crystal detector receiver made by taking
a pair of headsets and replacing one of the
headsets with a small detector in series.
I can't imagine where the little detector came
from.   Later, and a couple of years older, I tried
to make a detector from lead and sulfur, then
carborandum like they use for finishing concrete.
