Description

This simple kit allows you to build a complete high-quality digital Stereo FM Receiver capable of receiving radio broadcasts in 76MHz up to 108MHz band. It is a perfect FM Receiver to any FM Transmitter. This is an FM receiver supplied using two AA battery cells. This Electronic kit is for electronic enthusiasts to assemble by themselves, and gives you electronics knowledge, experience, and hands-on soldering fun, enjoy the test of successful soldering Job.

the circuit includes a  search tuning circuit, the signal detection circuit, a mute circuit, and a compression frequency offset of the frequency-locked loop FLL circuit. IF the frequency of the circuit is designed to 70KHZ, peripheral circuits without intermediate frequency transformer, wherein the frequency is selected by an internal RC circuit IF filter to complete.
