In Europe, radio frequency jamming equipment is limited, and in the United States, it is prohibited. Bonus Tips & Knowledge About Radio Frequency Jamming System It is possible to employ this design to jam radio stations that broadcast on FM within a radial distance of 40 meters or even more. The frequency that this circuit could jam is anywhere from 50 MHz to 1 GHz, but adapting it to different frequencies higher than 500 MHz could become much more complicated, with parameters becoming much more critical because higher frequencies necessitate shorter links and could cause various difficulties with stability. Generally speaking, a simple circuit for an RF signal jammer is made to jam all types of RF signals within a 5 to 10-meter range.īy simply utilizing alternative sets of L1/L2 and modifying the 22pF trimmers, the circuit may be made appropriate for jamming any chosen frequency.
Your circuit’s peak resonance is now set, and you may expect it to perform at its best.
Ensure the flyback & the driver are connected attach the antenna to the spark gap Many directions for making homemade flyback secondary coils may be found online. To get a higher voltage, connect two or three coils in series. The coil must be no more than 1 mm thick! In this case, instead of paraffin wax, use epoxy! Paraffin is easily melted. (It can be stretched to 20mm during operation.)īecause high secondary voltage can easily ruin the original coil, a homemade thin secondary is advised if you want to pump more watts into the flyback. The flyback requires a 20W power supply to operate and produces 8-9 mm sparks. Paraffin wax is used to impregnate the coil. The internal arc between the windings is avoided. The coil thickness is 1 mm, and the magnet wire is 0.1 mm (38 AWG). This way, the ultrasonic vibration is reduced. While setting up the flyback, remember to position the ferrite cores while ensuring the plastic plates are between them. After that, put in place the secondary and the new primary along with the feedback. Make a little hard paper cylinder and stick the primary and secondary coils to it by using glue. Take out the original main coil of the flyback.
You’ll need an antique black-and-white TV flyback transformer. The flyback primary and secondary are not soldered to the driver circuit instead, screws are used to secure them so that different flybacks can be mounted later. The driver is a prototype with a small heatsink, and the transistor heats up quickly. To protect the transistor from voltage spikes, a fast diode is advised. Wind the primary and feedback coils in the same direction. If you want to assemble a homemade RF signal jammer’s circuit, check out the 3 steps as demonstrated below: 1.
