yes, interestingly, there was an article in 73 magazine IIRC some years
back which described how to retroactively add IF shift to some older radio
receiver(s) using only a handful of parts, basically just add ability to
tune or shift the IF oscillator up or down in frequency so as to move it
w.r.t. the IF chain etc. I had envisioned a far more complex circuit,
based on its relative rarity, but it turned out to be a lot easier circuit
than I expected...
