FM Radio Receiver

The circuit schematic drawings FM Radio Receiver and its components and how to make it FM radio receiver circuit is composed of simple components are widely available in the market. However the output of a simple FM radio receiver circuit is quite satisfactory. The central component of this series just a FET transistor that is widely available in the market. IC LM386 in the circuit above is used as an amplifier output signal, while VC1 is a Varco (Variable condensator) that serves as the tuning frequency. If you do not want to use IC LM386 as an amplifier output, the FM receiver circuit is possible to use your own amplifier, you can make a separate amplifier by connecting the input with the output from the foot of C6.

The series is also equipped with speakers so you can immediately hear the broadcast that was captured. List of components to create a series of FM Radio Receiver A.
