@imgemini
Are you able to take a picture of your noise generator´s output signal with an oscilloscope? This would help much.

ok i will take the picture of my noise 0gen signal and wil try this circuit also
but i want to know why its not shopwing anything on ths ouput pin when i give
13.5v dv noise signal
Vcc =10 output= anthing
i hope i conned right wire bcoz it not Coaxial Cable

hello...
....maybee our ne555 circuit deliver to less output....!!!
(damn ne555!!!)
try messure with and without connect to the VCO...
so you can see how much ne555 able to drive ...!!!
send some picures with voltage per division and time per division.
so i can read our circuit right.
Chris
p.s. better use my sawtooth circuit (8->) !!!

These pictures are not useable for anyone without descriptions like volt per division and time per division...
The 2nd picture: You have measured the POS1060 output?? What is your oscilloscope´s bandwith?
-------------------------- The sweep frequency to modulate the vco has to be "high". If the sweep frequency is too low the jammer won´t work, because the gsm error correction can handle short interferences.
To get a higher frequency, change R1,R2,C1. I have mentioned it above already.
@ Chris Everyone uses/knows the NE555. I don´t like it, too. I don´t know why
