[Elecraft] K2 - KSB2

Christophe,

Look on the other side of that crystal envelope.  You should find a 
number penned in by hand.  That is the number you need.
It is the nearest 100 Hz increment that the crystals were matched to.  
The crystals are actually matched closer than that (I recall matched to 
10 Hz), but that number is sufficient for setting the filter properly 
later in the alignment procedure.
