As the proud owner of a Hallicrafters HT-37, I have long had a fondness for phasing rigs. It took me a long time to figure out exactly how they manage to drop the carrier and one of the sidebands without the use of crystal filters. This was one of the technical understanding battles of my radio youth, and is detailed in SolderSmoke -- The Book. (See the upper part of the right column of this blog for details on how to get the book.)
I was reminded of all this by a link sent in by Jim, AB3CV. It is an EDN design note, and describes a simple modern SSB generator using two phasing networks, three IC's, and a handful of discrete components:
