Just seen a reciever ( on the Open University here in the UK BBC2, 03:25
BST ) built from a variable capacitor, a coil, a wire antenna and a set of
headphones. Not a crystal in sight! It was briefly explained but not well
enough to put it together. Does anyone have a circuit diagram for such a
device? It would make a splendid wet afternoon project.
