FM radio transmitter
FM RADIO TRANSMITTER CIRCUIT How to make FM radio transmitter circuit at home on breadboard using one transistor .CIRCUIT DIAGRAM is in the link below. The circuit made by me can transmit audio at frequency 90.7 MHZ on a radio. This can be a small mini project for electronic students. Try it on your own and enjoy. Things required: *2N3904 transistor *10pF capacitors x 2 *10nF capacitor x 1 * 1nF capacitor *470 ohm resistor * Condenser mic *10k ohm resistor *Copper wire for inductor * 9v battery How to make inductor :- to make inductor take 10 to 15 cm of copper wire and wind it around a rod such that it looks like a helix. NOTE : 0.01H of inductor should have 5 turns of naked copper wire .
