FM TRANSMITTER CIRCUIT
FM receiver circuit works on small microphone to capture the sound and some transistors to generate radio waves.
WORKING
FM Transmitter circuit consisting of microphone and some resistors to get it working.capacitor and the first transistor. The transistor amplifies the weak signal to strong for enough strength. The last part, there is a transistor, a coil and some capacitors.This part generates the radio waves and combines them with the sound from the mic to transmit it thru the antenna.The coil is made with about 9 turns of wire, use a pencil to get the
right diameter for the coil. The capacitor with the arrow is called a
trimmer capacitor, it has a small screw to adjust the value, we'll use
it to tune a certain frequency or station to transmit on.
