yes, interestingly, there was an article in 73 magazine IIRC some years

Sounds like a worthy article, and a VERY worthy project. Is there somewhere I
could find this article online (or a similar project for retro-fitting IF
shifting to older receivers)?

Assuming the same issue had an article about adding an FM detector to
old shortwave receivers, I don't think the "IF shift" article is
worth tracking down.

Unless the description was horrible, the thing made no sense. My recollection
is that he put a varicap across an IF transformer, and called that IF shift.
Tha author showed no understanding of what IF shift was.
