I'm not for prohibiting ownership of as that would break a lot of companies test programs including the one I work for as we have a spirent in a cage to test LTE systems. And every avionics shop would be out of business
But if the FCC catches someone USING a jammer to access to GPS i dont have a problem with FCC throwing book at miscreant There is a big difference between unintentional interference and actively disrupting the only publically available precision navigation and time source Keep a jammer up long enough near a cell tower and you can bring tower down as well. Where do you think all those Tbolts come from. And because of GPS you no longer need a Cs reference in the CO for clock as you have all those flying clocks up there Sent from my iPhone On Jul 29, 2013, at 12:23 PM, "J.
