88MHz to 108 MHz simple FM radio receiver circuit
This extremely simple FM radio receiver circuit is made possible by the
special purpose TDA7000 IC. It integrates nearly all the functions
necessary to build an FM receiver needing only a few external capacitors
and a tuning circuit. Using a simple active RC filter made of only a
single inductor, a few resistors and a varicap, this FM receiver will
pick up broadcast radio between about 88 and 108 MHz. The mono output
signal can then be used to drive a set of high impedance headphones,
