Brief History
Crystal radio sets were the earliest form of radio receiver and used particular crystals both to power the radio and to convert radio wave signals so that they could be listened to. As the sets didn’t need batteries to power them and were quite simple to make, they were able to be small, like this Marvel Vest Pocket Set. Crystal radios didn’t produce a loud sound, and the earpiece in this set that provides a convenient and personal listening experience was actually an essential part of most crystal radio sets.
