[Elecraft] K2 freq set - why is WWV off-freq?

[Ron D'Eau Claire]

That is certainly true for CAL FIL, but the process that calibrates the =
dial
is CAL PLL, not CAL FIL. CAL-PLL does not require making any changes to
write new data to memory. .

You are absolutely right about getting the best possible frequency =
accuracy
being one of the "never ending" threads. It seems to me that's because =
it is
a never-ending question.=20

In the recent (and seemingly never-ending) discussion about setting the =
K2
Control board 4MHz oscillator, there is something may have been =
overlooked,
namely that when you THINK you have re- performed a CAL-FIL, it may be =
that
NOTHING has been accomplished!

This may explain why your K2 shows a frequency error (e.g. a reported =
80Hz
or more) when SPOTting on WWV instead of the +/-20Hz to be expected =
after
careful 4MHz alignment.
