![]() ![]() RF Jammer Coil Specificationsįor making the RF jammer compatible with other frequencies, the coil L1 and L2 must be shortened in terms of their number of turns and/or also the diameter.this will need some experimentation until the right frequency is determined. Your peak resonance for the circuit is set now, and you can expect maximum efficiency from it. So go back to the left side 22p trimmer and fine tune it again to set the desired frequency back into place.This might disturb the initial frequency of the system that you might have set for the jamming purpose.Adjust the right side 22p trimmer such that the meter reads around a maximum of 3V on the meter.Connect a 0 - 10V DC voltmeter across the point "test" and the ground line.This can be done with the following points: The performance of the RF jammer could be highly improved by adjusting the presets to produce peak resonance. A simple flexible wire measuring about a meter would also do but would reduce the transmission strength by about 60 % making the unit much inefficient as far as the transmission range is concerned. This could be any ordinary aluminum dipole yagi antenna. However in order to implement an optimal transmission of the signals, 50 OHM impedance antenna must be used with the output of the circuit. ![]() The above feature is perfectly complemented by the T2 stage which accepts the oscillations from the T1 stage and amplifies and transforms the signals with much higher current so that the signals are able to travel across larger radial distances in the air. The circuit is highly stable and doesn't falter with varying input supply voltages due to the presence of the 78L05 voltage regulator at the base of T1 which clamps the base of T1 with a constant biasing current making sure that the oscillations created by the T1 stage stays very stable and consistent. The above strong RF carrier signals transmitted by T2 may be appropriately modulated with any external frequency such as an audio or speech by feeding the signal across the terminal indicated "Test". ![]() The one comprising T1 and the associated parts form the RF oscillator stage while the other stage consisting of T2 and the complementing parts for amplifying and transmitting the low voltage oscillations from T1 into the air. The circuity of the proposed RF signal jammer is basically made of two distinct stages: RF Circuit Stages The present design can be used for jamming FM radio stations situated in the within 40 meters radial distance or even higher. The frequency that could be jammed using this circuit could be well in the range of 50 MHz to 1Ghz, however making it compatible with frequencies above 500 MHz could get much complex and parameters much critical owing to the fact that higher frequencies require shorter interconnections and may involve other stability issues. Please advise regarding your interest to help, and your financial requirements. I am self taught and can follow a schematic and complete a project, and am slowly gaining understanding of the underlying theory. I am not overly skilled in electronics, and only come to it in self defense. Up until now, most of the interest has been placed on projects of invasion and abuse, such as those contained on many different website As for electronics, some circuits to control the misuse of flux & solder are long overdue in the marketplace. We all experience an invasion of our personal lives/finances and private conversations, and are sometimes physically stalked and attacked.ĭue to the nature of electronic harassment, it will take time for justice and protection to catch up and solve the problem. There is a growing community of victims of electronic harassment. Jamming range limited to around a 25' x 25' area. I am only looking to jam (1.) remotely controlled harassment devices and (2.) spyware within the confines of my property. I realize jammers are illegal when they disrupt cellphone communication and commercial enterprise. I am in need of a circuit which will jam RFsignals. I am not a large business interest, but am in need of a circuit which would not only help me, but eventually be welcomed by just about everyone now alive.
