i am curious exactly what you mean by "image".
are there specific freqs or do you have to jump around looking for
loose ends.

Im a retired engineerbut I am retired due to strokes.

From what I remember, an artifact of a superhet receiver's oscillator
may fall within the band you're receving, like if it has a 455kh if
frequency, you may have an image of strong stations as if the
oscillator was running on 1365khz (3x455) and many other combinations.
Sometimes you can supress this enough for it not to be noticable.

They make say 25mhz to 1500mhz receivers nowadays and afaik they all
have the "image" / "birdie" problem somewhere on thier dial
