Lou,

The Eton E1 also has a very good synchronous detector which differs from 
those on other receivers in that you can select upper, lower, or both 
sidebands.  I've also heard that the Lowe HF-150, a British receiver from 
the 1980s, has an excellent sync detector, but I've never actually tried 
one.

Steve
