[Elecraft] Are matched XTALS needed for new K-2, KSB2

[Don Wilhelm]

Brian,

The crystal sets included with the base K2 and the KSB2 option are matched
sets already, so you should use them.  There is no need to have the crystal
sets for the two different filters exactly matched (the 2nd crystal filter
in the base K2 is broad) - you will actually have two sets of 7 matched
crystals rather than 14 matched crystals - just don't intermix them.

The reason you changed the crystals in your older K2 was because Elecraft
tightened the specs on the crystals that they were buying, and the newer
crystals were much better than the older ones - that is just history now and
all crystals should be coming in conforming to the improved motional
inductance spec.
