Circuit Diagram of FM Transmitter:
The circuit use only single Transistor but good voice quality. This circuit is vary simple and uses few components. Main parts of the circuit is R & C (Resistance & Capacitor) circuit to produce RF at Required Frequency band.
At FM receiver side Radio waves (oscillating magnating lines) produces current in Arial. Which is further amplified, Demodulated and feed to a speaker.
Parts List:
Capacitor =10Mfd, 0.1Mfd, 0.001Mfd, 2.2pf, 4pf, 5pf, 27pf, 68pf.
Resistance =3.3K, 2.2K, 3.9K, 220Ohms.
Transistor =494B
Mic =Condenser Mic
3v Battery with Container, switch Arial
