Voice Scrambling Systems
From The RadioReference Wiki
This page describes some of the voice scrambling systems you may encounter. It's unlikely that anyone (apart from the intended recipient) will ever get anything useful out of these modes.
Waterfalls of these systems can be found at the Voice Scrambling Systems Waterfalls page for easy reference.
More information can be had from the HF Asia, Signal Identification Wiki and the Antonio I5-56578 Blog; links for all of these can be found in the HF Appendix.
