schema jammer fm

There you go gents, all you need to do is ti get a Nokia 6310i, then patch a new signal into the AF of the PA amplifier with the power set to full.

Re: GSM JAMMER

Cell phones use many different frequencies (in most countries) so it is difficult to jam all of them at the same time.

Cell phones are used in emergencies to call police, an ambulance or the fire department so it is illegal to jam them (in most countries).

Re: jameergsm circuits

i have some information

L1 L2 L3 L4 = I assume that a ferrite core inductor could work .... recommended site www.coilcraft.com

aaand this is the information about IC's in the jammer

947T= VCO sirenza microdevices

RF2104= medium power amplifier RF microdevices

MAR7= monolithic amplifiers------ mini-circuits

i hope this help you.....see ya

Re: GSM JAMMER

Dear schafaque,

please read something related to VCO and jammer before posting...

anyway to cover the whole spectrum of a gsm downlink you need to drive linearly a VCO with a triangular voltage wave so that the frequency goes from 925 MHz to 960 MHz
