Before you enter:
This item is illegal in certain locations. It is only demonstrating how these items work and what only a few dollars at a electronic store can build.
This also Not a Cell phone jammer. Jamming a Cell phone is similar on its principle, but totally a different build, you need a range from 800MHz to 900MHz. You need an OP amp and a few other parts and formulas
F = 1/(4*R1*C)*(R2/R3)
R3/R2 (noticed it flipped) is the frequency range
850MHz = 1/(4*R1*C)*(1/50MHzS)
You must know the fact that they are illegal in certain areas and MUST NOT rant about it and say they are illegal.
Step 1: Precausion
I am not Liable for any offenses.
Why This Works:
The Radio Jammer sends out a EM wave at a frequency. The wave is then broadcast throughout an area. Radios will receive this wave (when tuned to that frequency) and It will block the other wave that is broadcast from a station.
So far in my building, I have only been able to block 1 station using one OSCILLATOR.
Have tried adding 1.5v onto a 9v battery. This unexplainably let me listen to another channel on the channel I was blocking.
