Left and Right refer to the bottom left and right pins of the pots V1 - V6.

It appears that V1, V3 and V5 set frequency and V2, V4 and V6 gain.

V1 and V2 look to control 3G as tweaking it affected an AT&T 3G phone.

V3 and V6 look to control DCS which affected my T-Mobile phone.

V5 and V4 look to control GSM which also affected my T-Mobile phone.

You can find misc info at Deal Extreme on the jammer’s page and Instructables.

Contact me at bile at landofbile dot com if you have better values more more accurate information. Ideally we’d like to maximize range. Is there a way to increase broadcasting power?

Contains a HEF4066BT and a NE556. I’m unable to find data sheets for IC 1 (KC DDC1748F), IC3 (9P3-1880 D017), and IC4 (9PD-1880 D133).
