This 2x LO is exact the same as used in the great "QRP2001 Project"
by Jan Verduyn (G0BBL), Steve Farthing (G0XAR), John Law (G8BTR) and
Alan Rowe (M0PUB).

I just downloaded the a schematic of my Tayloe Detector. It
requires LO at 2 times the RF rather than 4
times. I just tested it yesterday using the Micro 908 VFO output as
the LO. Using the SDR program, I was
able to get close to 60dB opposite sideband supression.
The first 74XX86 converts the sinewave to a squarewave. The next
two, produce a 0 and 180 degree output.
The fourth gate provides an easy way in hardware to select the sideband.
