Hi,
i love eletronics field and i've been working on few projects since 4 months. anyway, I've been looking around for a phone signal jammer for 800mhz or more , i tried few simple circuits but nothing works, some of the problems i have that i cant make a coil of 2nH or 20nH i fear that would be the problem they dont work, also how can i verify that these circuits actually work ? thanks
