This project is one that
is easy and cheap to make/build. It has also been the base for
experiments with other circuits. The Fox Hole Radio is said to have
been borne of the trenches of ww1. The soldiers were in dire want of
news of the front, of news of home, particularly with the American
Expeditionary Force the baseball scores from home. Battery power
sets were not allowed as the German radio forces could RDF (Radio
Direction Finding) the LO (local Oscillator) in the battery powered
sets.
The Fox Hole Radio is
nothing more than a Crystal set, it will receive Am radio
transmissions, the crystal receiver was the 1st common
receiver available to the general public. It also requires no
outside or external power source. Which made it ideal for the people
of the time to listen to what was the internet of that time. Crystal
sets range from quite simple to very elaborate. It mainly depended
on the individuals resources and abilities to build.
The very basic components
of a Fox Hole / Crystal radio is the base, the tuning coil, the
detector, the cats whisker, and a set of Hi-Impedance headphones.
The rub here is that the headphones are not really available in
todays era, however there are ways around this problem. Which will
be covered in a bit.
The rest of this article will be on Amazon shortly
