There are some homebrewers who do not-completely-suppressed carrier
with synchronous detection. It's sort of SSB but not traditional ham
radio SSB. In traditional ham radio SSB you try to suppress as much of
the carrier as you can, and this won't help you synchronously
demodulate it.

I got the impression he was using an I-Q system to implment a hilbert
transform. The result is an image suppressing system that can
demodulate SSB with a baseband IF.

Essentually what a KK7B R2/miniR2/R2pro(RX) and the companion T2
(transmit) using aboth a 90degree I-Q RF path and an +45 and -45
degree audio processing path.
