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
circuit, but the original speakers` voice will not be identifiable with
correct adjustments. Two LM324 op amps act as oscillators that are
tuneable from 2 to 3.5 kHz. The frequencies are set with R12 and R13.,
T2, and T3 are 600 CT/600 audio.
