I recall reading somewhere that the KWZ-30 had a unique method of
handling AM signal fading. It wasn't synchronous detection but
something else. Does anyone remember what it was?

See page 13 here where it mentions the AM demodulator, that may be it:

Yes, that's it. Thanks!

The KWZ-30's audio quality is the best I've encountered on any HF
receiver. And I've had a few. And their Auto Notch function is second
to none - totally transparent when selected, and with practically no
effect on recovered audio quality.

Are they still in business? The last time I tried to visit their
website, it was gone!
