FM Snooper Transmitter Circuit

FM Snooper Transmitter Circuit

The FM Snooper is an FM transmitter that radiates a continuous wave whose frequency is altered according to the sound waves striking the microphone. An ordinary FM broadcast recelver detects the transmitters output carrier. When 9-V battery, B1 is connected, a brief Surge of current flows from the collector to the emitter of Q1, causing an alternating current, shock oscillation in the resonant LC circuit to flow back and forth between L1 and C5. By varying the value of C5, you can tune the oscillations to the exact frequency desired. Credit for this circuit goes to: www.seekic.com. I have done all of the circuit board artwork, breadboarded circuit and stripboard circuits for you. Enjoy. John
