This simple fm radio receiver circuit consists of a regenerative rf stage, TR1, followed by a two of three-stage audio amplifier, TR2 to TR4. In some areas 3 stages of audio amplification may not be necessary, in which case TR3 and its associated components can be omitted and the free end of capacitor C5 connected to the collector of TR2.
This is a fm radio receiver circuit which can be used with PC.
PC radio REGULATIONS
A) With the P1 we regulate the intensity of sound.
B) With the P2 we regulate the frequency of reception.
C) Optionally: If you want to check the frequency with your PC it will be supposed you make the following energies:
