The idea here it to be able to construct a crystal radio with parts fabricated right at home. This can get complicated in some areas of the radio as it is difficult to get some items needed. Also some parts of the radio are very complicated and detailed. We will attempt to simplify the parts as much as possible so we can “homebrew” or make them at home (as much as possible).
