It works, you need to rotate the crystal around to find a good contact, and it's a bit easier than fiddling with a cat's whisker in some ways. I managed to get some good results in testing but it does have a couple of drawbacks. Firstly it's pretty dangerous! Seco...")

• 07:15, 20 June 2026 Cornish semiconductor talk contribs created page Historical cat's whisker designs (Created page with "right Crystal radios from the 1920s are possible to get hold of, but can be quite expensive. This is a collection of photographs and diagrams of crystal/cat's whiskers setups that I've managed to find. The materials used correspond with what was available at the time, glass, metal but also the first plastics, ebonite and bakelite - which would have felt very futuristic in these years. On the right is a diagram of a vertical set up. This...")
