The reason that I ask is because I have a Bruhan's VLF converter that uses,
what he called, a ring mixer. The Burhan's converter has a MC4066 analog
switch where the control inputs of two fet switches are inverted and the
other two are non inverted. When I saw the schematic of the H mode mixer,
it reminded me of the Burhan's VLF converter. The difference is the
transformers that Burhans used. They were audio transformers that covered
the VLF range.
