One of the ones I always wondered about came in the sixties and I'm
pretty sure was still in the catalog in 1971 when I would have seen
my first Heath catalog. It was a general coverage receiver, and looked
a lot like the average low end receiver. But it used an IF in the 1600KHz
range, using a two-crystal lattice filter. I've always been curious
about it because of that high IF which obviously would make an improvement
for the highest band in terms of image rejection compared to the usual
cheap SW receiver. But I've never really seen anything about how the
receiver was generally. A higher IF suggests something better, but
it might have just been as bad as the usual low end SW receiver.

I believe my old HR-10 used an IF of 1680 kc with a simple
2-pole lattice filter. Of course that was ham coverage only..

Yes it did. I was even going to say that the shortwave receiver I
was talking about might have been a variant of that ham band only
receiver.
