being a former commo sgt myself,i know there are ways of jamming signals
but to incapacitate the whole ham band is practicly impossible
theres just so many different repeaters and transmiters
sure you can block a few of them at a time but never realy turn it off
i keep saying to myself one of these days ill go for the liscense
lord knows i have enough gear and know how-just need to get off my duff and do it
