The traditional foxhole radio is made out of scavenged parts by some soldiers during World War II. This page documents that radio as well as improvements to help it work better. The construction of the radio is not very difficult and most people age 6 and up should be able to make one. This is not only fun project, but one that can dramatically increase your ability to get information when you need it most. This radio also takes no batteries for the basic model, instead it is powered entirely by the radio transmitter.
