A well-tuned jammer-------check by USRP
HI
just pick up some powerful 4 bands (30dBm/ant, done by two CLY4 GaAs FET) handheld jammer from a nearby city, nice stuff, do all cn cell chn eg. 2G,3G,4G date band and the most alsom---wifi
buc purchasing these stuff cost about 400rmb each, with a huge batt, bout 25Wh........and a fan inside

cuz i dont own these stuff, i wont post pic around, n DO NOT ASK ME ABOUT THE DEVICE ITSELF!!!!!!


==================================================
anyway, just got my b210 from ettus directly, i thought we should check the spec with it:

and........ it bang on!!!!(dk how to put the markers on it....)
with not much harmonic knocking around, im quite satisfied with it......
tech guy must hav put some effort tuning it, at least i wont get it that right, who care...
