Simple Crystal Radio Circuit Diagram. In order for current to flow a. The main components involved with this simple crystal radio set circuit are an ordinary antenna coil a detector diode an optional resistor and a crystal earphone.
Diagram of a simple crystal set showing the symbols used to represent the various parts ot the apparatus. The detector diode could be any regular germanium diode such as oa91 or 1n34a etc. The main components involved with this simple crystal radio set circuit are an ordinary antenna coil a detector diode an optional resistor and a crystal earphone.
The crystal radio schematic shown below is very simple and one can easily build it in few minutes if all parts are available.
Rf choke crystal radio 365 1 une spider wound on 3 inch form coil i d 314 inch o d. Diode d1 demodulates the signal which is fed straight to the earphones. The antenna of course captures the radio waves travelling through the air and converts them into alternating current. Building a crystal radio circuit is not very difficult and require a very little electronics or technical knowledge you can make it with 2 to 4 components in a very short time.
