Do a sanity check by listening to WWV. That will tell you if your
various radios are telling frequency lies or not.
The thing to be aware of is that the reference oscillators in the
respective radios will drift. There is a method using WWV in the K3
manual to check and adjust the REF CAL error.

Note that in the two cases mentioned, you reported 47 +/-1 Hz difference.
That is not much and can easily be attributed to a difference in the
calibration of the radio or the audio frequency accuracy of the soundcards.

After working a friend on 10 meters with FT8 I phoned and asked him
why he always stayed up high at 2454 Hz. He said WSJT-X said he was
dead on 2500 Hz.
I asked him what it said my frequency was. He said it was 1048 Hz; my
WSJT-X said I was dead on 1000 Hz. We did more testing at other
frequencies and on other bands and found similar discrepancies.
