Re: [TSCM-L] {2504} Re: GPS Scramblers A cell phone has a mi= nimum sensitivity.  That number is calculated in signal density.  = ; 

If you wish to jam/block a signal,  you need to calculate the jamming = transmitters field density at the range required and transmit to that range= with something larger.  If you want 10 feet away,  then every ti= me you double the distance you have to square the power to make sure you ca= n overpower you need a little more.  This is if you are truly omni-dir= ectional.

Now if you have something, anything in the way, then you have to add more.<= BR> --

The signal strength required would be very small for such a device and= is unlikely to fall under any government scrutiny.

If the device  disrupts gsm service its reasonable to believe th= at  it would fall under the cell jammer catregory-  illegal
If the device jams a  gps receiver and its not fcc approved its = probably  illegal
Whats interesting is Ive spent hours searching for the same answer, u= sing  specific language gps transmitter,,and nothing is etched in ston= e regarding the  legalities of a " GPS Jammer"
Interesting topic  though

I am assuming that GPS scramblers  that are appearing in various blogs= are illegal just as any radio scrambler  is.  Can anyone verify = this?  Thanks
