with the ground and antenna connections reversed. The diode is a piece
of galena.

Does "it works exactly the same"?

yes

I haven't read all the thread.


I always see the diode in series between the antenna and the headphones.

You will get a much louder audio signal if you connect a germanium diode

Electrons will move down through the earphones and up through the diode.
