I found a 1997 ARRL article on a capacitor tuned crystal radio. I've tried many of these and none worked. I started with this design and modified it for both looks and function (new earphones require a change, different coil design). It works very well. You can tune in even very faint stations with little to no cross-talk. This is a link to the video I made about its construction. It includes the circuit diagram. https://www.youtube.com/watch?v=AaNpFYe5dSo |
