FM Transmitter

Image of FM Transmitter                         Circuit Diagram of FM Transmitter The circuit uses only single Transistor but good voice quality. This Circuit is very simple and uses few components. Main part of the circuit is RC ( Resistance Capacitor )circuit to produce RF at required Frequency band. At FM receiver side Radio waves(oscillating magnetic lines) produces current in Arial. Which is further amplified, Demodulated and feed to a Speaker. Part List : Capacitor : 10 Mfd, .01 Mfd, .001Mfd, 2.2pf, 4pf, 5pf, 27pf, 68pf Resistance : 3.3K, 2.7K, 3.9K, 220 Ohms Transistor=494B Mic = Condenser Mic 3V battery with Container, Switch Arial http://www.youtube.com/embed/aAcDM2ypBfE This Video explains how Radio waves are produced.
