How do you build a foxhole radio? I saw a few plans on the internet,
but I don't understand them. I have read that you can use a telephone
receiver instead of crystal earphones. Is this true? Also, is it
possible to make a version without the razor blade? Sorry if I sound
stupid here. I am not an expert with radio. Thanks in advance.
The 'Foxhole Radio' is a type of crystal radio that can be built out of
scraps that could be found almost anywhere and so it was sometimes built as
a radio for soldiers to use.
There are many forms of crystal radios, most of the recent ones use a
diode that can be purchased at radio shack, or any electronics parts store.
This diode replaces the razer blade that was originally used as a detector
diode.
Here is a website that shows how to build one.

This website has more technical information, although it shows a slightly
different assembly for a crystal radio.
