Samcon Fm Radio Circuit Diagram. Remove the mandrel and stretch to the 06-inch length. The first transistor works as an RF amplifier.
IC1 is the micro power audio amplifier that works between 45 to 12 volts DC. This circuit is capable of producing the loud sound which is better than commercial radios. For L1 and L2 wind 5 turns of 06 mm enameled Copper wire on a 4 mm dia plastic former.
FM Radio Circuit Design.
FM Radio Circuit Diagram with Parts List. 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. For antenna use a 50mm long insulated copper wire. Just connect the components as mentioned in the text below.
