Dick,
It is easy to check your K3 or K3S (or any other radio). I suggest you
do so before concluding that your radio is off frequency.
Tune to WWV at the highest frequency you can receive in CW mode and zero
beat the carrier - you can use CWT if you are not good at zero-beating.
Make sure you are zero-beating the carrier and not one of the
transmitted tones. The tones come and go minute by minute, but the
carrier is always present.
Stations that cannot receive WWV can use of of the other standard
stations around the world.
If your K3 is off frequency, do the Reference Oscillator calibration and
check again.

I have a K3 kit that's been back to the factory for repair and alignment,
and a K3S that was factory made and aligned. Regardless which one I'm
using, most of the time when I get "spotted" by RBN, my frequency is listed as
being 100hz higher than listed on the K3's front panel digital readout.
This has often made me wonder if both of my K3's are slightly off frequency.
Could it be that many/most K3's are "slightly off frequency"?
