Hello Mike,

If you Google on "Synchronous AM Detector" and "Exalted Carrier Reception"
you'll find lots of info

This is good place to start....

Thanks Graeme,
I'm thinking about building the mixer that was in QST Feb., 1993, an
article by
Jacob Makhinson. Titled, "A High-Dynamic-Range MF/HF Receiver Front End"
The mixer uses a quad FET IC, (Si8901 from Calolgic corp.)
The only online reference that I can find is here; See pdf pages 26 (text)
27 (schematic)
http://files.bluecrow.net/Amateur%20...ok_2007/11.pdf
The front end is designed in three modules, preamp, mixer, and post amp.
Anyway I'm thinking about building the mixer and playing with it in the
AMBCB.
Even thoughts about building an I/Q receiver.
Mike
(Note; I do more thinking than building ;-)
