Simple Voice Scrambler Disguiser Wiring diagram Schematic

Simple Voice Scrambler/Disguise Circuit Diagram uses two balanced modulators to produce a DSB signal and then reinsert the carrier, except the carrier now has a different frequency. This causes an input signal to be distorted. A voice signal will be recognizable with this schema, but the original speakers` voice will not be identifiable with correct adjustments.
