Simple Ham Radio Antennas--Portable Crystal Radio using Loop Antenna and Pizza Box. Post #501
If you have trouble viewing this video, please enter this URL into your search box: https://youtu.be/iunAvz9PbN0. An excellent tutorial on how to build a portable crystal radio using a loop antenna coil inside a pizza box. The coil that the tuning/variable capacitor resonates serves as the antenna by being a very large coil. According to the maker, "Rimstar.Org," radio stations are found by adjusting the tuning capacitor and pointing the face of the loop at a nearby radio station. This crystal radio uses a crystal earphone and a germanium diode (1N344, 1N60, 1N91, 1N270, 1N277, or a 1N283). Silicon diodes can be used, but the antenna may need more wire to pick up a station.
