The method I've used to check my K3S, put the radio in CW mode, tune to
each WWV frequency and then press SPOT.   The automatic SPOT function
will bring the radio to the WWV frequency +/- 1 Hz. The SPOT function
matches the receiver sidetone offset of the WWV carrier and the audio of
WWV is not applicable.    If the display is other than the WWV
frequency, then adjust the REF CAL number to correct the error.   You do
need to check all of the WWV frequencies you can receive to assure the
accuracy holds on all bands.

Unfortunately we have come to believe that the digital readouts are
absolute, which indeed, they are not.  They depend on the internal
reference.  If the internal reference  is incorrect, then everything
else is likewise incorrect.
