[Elecraft] K2 PLL Ref. Osc. Range Too Narrow

Mike and all,

There is a note in the "What's New" section of the Elecraft Builder's
Resource webpage that says a PLL Range of 8.8 to 18 kHz range is OK.  It
seems that information has not made it into the Errata pages yet, butr I
expcet it soon.

As I understand things, a narrow PLL range is better than a wide one - the
PLL reference will be more stable.
