Oh, thanks, good to know. Now I feel more motivated. Because actually it’s not as easy as it looks from the text books. It’s like with drawing an owl. Yeah, pass the signal through a mixer and feed recovered carrier to its LO port and you’re done. Sure. Simple. Now just recover the carrier. So far I have built a PLL that locks to a clean signal but stops locking when the signal is modulated too much. Aargh.

I wish it was easier to buy a portable radio with one. Though admittedly I tend to use mostly vintage radios - as such I do most of my shortwave listening on a Zenith T-O which is pretty wonderful both in audio quality and capacity to pull in stations.
