Scramblers

Scramblers are electronic devices which, hence its name, scramble your voice over the air. Scramblers use voice inversion or sophisticated digital encoding/decoding of your speech. This prevents other radio operators using normal modes in standard form from being able to understand you.

Scramblers can be installed inside the radio or can be connected in series with the microphone or in place of the microphone.

Spread Spectrum

Spread spectrum could also be considered as a type of scrambling. Spread Spectrum is used mostly by the military because it has good security and antijamming capabilities. It also incorporates psuedo-random coding into it so it's difficult to follow the signal around. Spread spectrum communication is more complicated than normal RF communication. Spread spectrum is far more secure than an encrypted RF signal could ever be.
