This is the Super High Power Portable TV and FM Jammer Circuit Diagram. There are still neighbors that keep annoying you by having loud the
TV or the radio? Well I have you the solution. In fact all neighborhood
will face your jamming waves at their TVs and radios, so be careful.
This Jammer is the improved version of the old `TV and FM jammer
schematic` with the difference of much higher power. Many of you where
asking for a stronger and wider effect but to be as portable as can be.
Looking at the schematic you can see that, only the parts are changing
keeping the basic circuit intact.
Have in mind that this version needs heat sink and antenna to keep the
transistor alive.
Super High Power Portable TV and FM Jammer Circuit Diagram
The power source comes from three 9 volt batteries in series, so we use 27 volts at input, and we get a power full 2,5 Watts at output.
You are going to need 70cm to 2 meter simple wire antenna.
As for the transistor Q its the 2N3553. Its a RF Power Silicon NPN
Transistor in a TO39 type package designed to be used in amplifiers and
oscillator applications in military and industrial equipment.
Usually found as an output driver, or in predriver stages in VHF
equipment, but because here we don't care about the modulation of the
signal but just the power, that's why we use it as a first and final
output driver.
The transistor is specified at 175MHz and 28V to give: Output Power: 2.5W, Minimum Gain: 10dB and Efficiency: 50%.
The parts are: R1=10k, R2=2,2K, R3=100 C1=47uF/50V, C2=2.2nF, C3=10pF, SW=switch, B=Battery 9V.
The coil L should be closely wound 5 turns (start tunning with the
closely wound distance of turns and then play with it and the C4
capacitor, to find the desired frequency )of enameled copper wire 1.5mm
and internal coil diameter of 1cm (leads 2x20mm).
The variable capacitor C4 should be air trimmer capacitor rating 4 to 30 pf or the closest to this value.
Connect the batteries in series place the best heat sink for TO39 case
you can get and pack it all in a small plastic box. Enjoy ;)
