I suggest you use the K3 Utility and a known good 50 ohm load and
perform the complete TX Gain Calibration. Connect the radio to the 50
ohm load with a short, single jumper of known good quality. There
should be no switches, amps, power meters or such in the line between
the radio and the load.
Also when powering down the station, be sure to turn the radio off first
before turning off the power supply. There is a power down imminent
circuit that saves data and then shuts down the radio. If you kill the
supply first, well that circuit won't do its job.

Does it happen on more than one band?

I am experiencing the Power Creep issue on my K3S.?? This radio was just
returned from Elecraft repair in June of 2020.? At that time I had the issue
with distorted audio above ~12 watts.
I have read prior info regarding the power creep issue.? It is not related to
audio level as Don mentioned.? I did not do a new calibration as it was done
at Elecraft just 6 months ago.
The only way to get the full power at any setting (20, 50, 100 and so on) is
to put the radio in RTTY FSK and key up about 5 to 10 times.?? If I turn the
radio off.?? The issue comes back.
Is there any new information on the cause of this issue?
It is very frustrating to have a radio that cannot drive my amp or put out
proper power without all of these steps to manipulate the power.
