[PCR-1000] PCR1000BUR1v2 Explanation?

[Roger Kolakowski]

Personally, this is one I would probably not touch without test equipment.
Typically a phrase such as that means how they "drew" the IF crystal onto
the exact frequency that makes all your stations be where they are supposed
to be on the dial. It's convenient to have the stations where they are
supposed to be  ;-)

BTW...crystals can vary widely from their designed frequency, so most
manufacturers have designed "padding" capacitors across them to put them on
the correct frequency during initial alignment. Any figure here could be way
out of average and still be correct.
