Radio Receiver Circuit Diagram. Remember the circuit also acts a like an effective transmitter circuit therefore keeping the antenna size bigger would mean transmitting noise across the ether and disturbing your neighbors radio. Marian 01122010.
The antenna in the proposed single transistor fm radio receiver circuit is not crucial and in fact should be kept as small as possible a 10cm wire would be just enough. Schematics and circuits index index radio receivers regenerative. Which gets the signals through the antenna which acts as a receiving wire.
