I've seen the regeneration in the Kiwa loop demonstrated, and it's
certainly an *interesting* feature. I'm not really convinced it's all
that important if the attached receiver has adequate selectivity.

(on the other hand, if you're thinking about selling the antenna
stand-alone to people who want to use it with someone else's receiver,
the regeneration may be worth doing)

don't want it to suffer the R75 curse! I have been revisiting the Analog
Devices AD607 chip; this would make Sync AM possible, but this chip doesn't
have envelope detection. Analog Devices only has an application note for a

Speaking just for myself, I think if there's a decent synchronous
detector, there's no need for an envelope detector.
