[Boatanchors] double-sideband suppressed-carrier

[Howard Holden]

The Navy used ISB from at least the early 60s. Most of the later synthesized 
TMC transmitters have ISB capability (with the proper modulator). As Bob 
said, voice on one side, data, 16 channels or more, on the other. An R-1051 
works well, or, with a really good Rx operator who can distinguish the 
necessary tones, the R-390A with converters and audio filters will do. Their 
signals sounded like a bunch of McCulloch chainsaws run amok.

That's something entirely different from what Costas proposed.
