I tried an experiment with a very small
loop I have. (I have used this loop for
lots of things including CC coupling attempts.)
This loop is about 15 or 20 inches on a side. It
has multople turns of wire and is tuned with a
365 pF variable cap.
I hooked the loop up to my crystal set without
an antenna and without a ground. I was able
to hear our local 50 kW flamethrower. It was
there with very low audio in the headphones,
but it was there. So – I guess – that small
loop and the RF section of the crystal
set were able to turn on the 1N34 diode
in the crystal receiver. What does that
take? 0.3 volts? That’s not too bad to
a small loop like that.
