[Boatanchors] SSB and carrier insertion?

[SBJohnston at aol.com]

Synchronous AM detection is an example of a detector that uses both upper and 
lower sidebands... two outputs are available - all stuff in-phase with the 
carrier and all things 90-degrees out of phase.  Matrix those signals with an 
appropriate phase shift network and you get selectable upper or lower sideband 
audio.  See my materials at   http://www.qsl.net/wd8das/    specifically 
http://www.qsl.net/wd8das/sync.html

Can be used with full carrier DSB (AM) or reduced carrier DSB or SSB.  Best 
readily available example of this technology is the Sony ICF-2010 receiver 
(ICF-2001D in some areas of the world).
