Build a crystal radio receiver
using a point contact diode.
These are vintage point contact germanium diodes
made by ITT.
They work great in crystal radio receivers.
The point contact is clearly
visible through the glass
(use a microscope or magnifying glass to see).
These are high quality crystal diodes with a gold wire
making the contact.
They are rare - point contact
germanium
diodes by ITT have not been made in decades.
Newer
germanium diodes
are typically not made with a gold
wire point contact, and are made with less refined germanium.
Most standard diodes (including common silicon types)
do not
work well
as a crystal detector.
The best are point
contact
germanium with a low
forward
voltage.
These
diodes are
guaranteed to work as crystal
radio
detectors.
The part number on the diode is: ITT 1N270

These are 100% Guaranteed.
You will receive 4 Crystal Radio Detector Diodes
with Buy-It-Now.  While they last.
~ Recent Customer Feedback ~
"A heartfelt thank you for your divine rare ITT Point
Contact Diodes!"
"I ordered these and they put out twice the mA of the Soviet D311A
which to date I thought was the loudest diode (in my crystal radio)."

Or you can buy marginal diodes from overseas
(China)
and wait 3 months for delivery...I'm just sayin'
