FM RADIO JAMMER

1. This circuit can be used to jam FM radios.
2. The circuit is nothing but a classic signal transistor oscillator operating in the VHF region.
3. Working principle of this circuit is very simple and straight forward.
4. powerful VHF oscillations from the circuit will interface with the FM signals to nullify it.
5. This circuit is intended only for fun and i request you not to misuse it.
   
   NOTES:
6. For L1 make 6 turns of 16AWG enamelled copper wire on a 9mm plastic former.
7. The circuit can be powered using a 9V PP3 battery.
8. For extended range, use an antenna.
9. A 30cm long wire connected anywhere on the coil will do for the antenna.
10. For better performance, assemble the circuit on a good PCB.
