Warbley police in the 20th century

The article contains no discussion at all of the common types of basic analog secure voice techniques (such as voice-frequency-inversion, precoded multiplexing,... all non-digital methods of obscuring and/or encrypting voice channels). These were used rather common in the 80's and 90's among police services for example (10+ years ago my scanner would catch 137-140MHz 'warbley' voice conversations that were clearly local and federal police agencies). By now they have been replaced of course in most implementations by digital encryption and processing methods.

Food for thought... Then again Wikipedia tends to not contain any information on non-popular (yet accurate) content anyway.

Well, yes, being comprehensive is not what an encyclopedia is about, especially with small, quaint oddities. Perhaps we should include a link to a Web page that thoroughly covers these unpopular, antiquated methods. Are there any? Jim.henderson (talk) 15:33, 6 April 2009 (UTC)[reply]

SIGSALY misrepresented

The article currently misrepresents SIGSALY, which was a fully digital system and way ahead of its time. See SIGSALY and its refs. — Preceding unsigned comment added by Rqb (talk • contribs) 10:53, 25 June 2012 (UTC)[reply]

Ciphony

I plan to rename this article to ciphony, which is the correct scientific name. scope_creep (talk) 10:32, 30 January 2018 (UTC)[reply]
