[Elecraft] K2 PLL reference oscillator problems (DAC side!)

[Don Wilhelm]

Ryan,

Those sub-par J310s should work in all other circuits in the K2.
The only other possible exception is Q18, but if you can successfully 
run CAL PLL, then all should be OK at Q18 as well.

The problem J310s at Elecraft was resolved early this year and the 
incidences of this problem should be diminishing soon.
