You might find that part of the waveband is 'bunched up' at one end or the other. Oddly enough I had an FB10 that had it's IF tuned to 465K but had also been heavily 'got at'. I attempted to return it to original and partially succeeded and retuned the IF's to 422 but I could never get it to track properly and sensitivity and selectivity was very poor. I even had the transformers apart to see if any dastardly deeds had been done inside them but couldn't find anything. In the end the FB10 in question was used as spares to fix a much better one which I now have.
