Pls help with mobile call interceptor circuit(spyware)

[x__heavenly__x]

I was just getting bored so cud someone pls come up with a link or information on how to make a mobile calls interceptor for frequencies upto 900~1200 Mhz??...and the circuit diagram if possible.

 

Help will be apreciated.

what are you trying to do exactly?

 

Hijack calls? block them? are you on about "Toothing"?

give us a bit more to go on plz

Like listening to call in a radial area. Like 5+ meters or so and blocking is interesting too.

well being able to pick up the digital signal is very easy, you`ll only need a scanner. the problem will occur when strying to decode this as the ESN and IMEI are needed as part of the decryption sequence. using s/ware and a brute force decoder/scanner it would be possible, but the call would be long over before you got a hit

blue tooth enabled fones or computers are quite easy tho`

jamming isn`t that hard either, you only need a mobile fone and bypass the filters and hardwire the transmition end, giving you a broadband carrier with which you may overlay any signal you wish (White noise is good), you can get that from any of the I.F stages

I can try to get the scanner but

1. Is it possible to jam a call using just a mobile phone and edit its circuitry

2. Pls if u have any links on this.

3. Your Personal site contains maloch link which has some servalence tips. (and the site is great )

1. yes, I mentioned how in my last post, although it DOES assume a certain level of competance in electronics, that part I can`t help you with, and if you`re not furnished with a circuit diag for that particular fone, a certain level of trial and error is involved.

 

2. nope sorry, I have no links, I made this device myself using the method I stated so I can`t really help you there

 

3. yeah it`s a link I deny having and thnx, it needs a good update tho!

hey yt2095..... i wanted to build a mobile phone jammer/ overrider. but i dont have a lot of knowledge on this........ i could be able to tackle it if you could give some initial guidelines........ maybe even a circuit..... would be greatfull.... by the way.... cool hair do.
