Interfere with fm radio signal is fun, if you're bored or no work, you can do at home, where neighbors , at school , or even near the transmitter. With the circuit above you can interfere with the speech signal in condenser microphone , and the signal will be issued by the circuit will then be received by FM radio receiver and a voice that we remove it before going out mixed with the signals emitted by radio FM transmitter. Part List : R1  = 4K7 R2  = 2K2 C1  = 1n5 C2  = 47pF C3  = 33pF L1  = Nikelin wire coil with a diameter 0,8 mm and 5mm in diameter wound coil 10 x T1  = 2N3906 Mic= Condenser Microphone If the circuit does not work on the errors may occur : Installation of the opposite transistor , incorrect placement of components , less voltage, the voltage is too high , the microphone is broken, transistor is damaged , broken coil . Please note this circuit can work and receive FM radio reciver at distance of about 500 meters. And not to much use...
