But if you REALLY want to do it right, you wind your own coil on a
shellacked oatmeal box.....or, a shellacked salt box.
All of mine used a germanium diode and a prewound coil, so there.
I'll shut up now.

"A computer without a Microsoft operating system is like a dog without a bunch of

I read somewhere that a piece of coke (the fuel,
not the drug, OK
:-)) was used by POWs in the second world war as a detector. Using
much the same cats whisker arangement as with the galena crystal.
Might be worth
a
try.
I will work but you want to find a peice that has really been fired
and has a bit of rainbow color to it. IT's the contaminating oxides
and all that makes it work though germainium is better.
I would recomend getting the set working with a
germanium diode
first. Then, when you know the coil, tuning capacitor, headphones,
aerial, earth, etc are OK, try the home-made detector.
Good way to go.
