The crystal receiver was one of the first radio receivers and is actually a simple version of a radio. The receiver consists of a coil, capacitor, crystal diode, and headphones. To receive signals an antenna is also required and it must be earthed. The receiver can only receive amplitude modulated signals that are not too far away; it cannot receive FM signals.
