Bret,
This is a condition we call "Power Hunting", and it usually indicates
that you do not have the audio level set correctly for Elecraft
transceivers.
Are you driving the audio to illuminate 4 bars on the K3S ALC meter with
the 5th bar flashing? You must operate Elecraft gear differently than
other transceivers because of the closed loop system used for power
control is different than the simplistic "control the drive level"
system that other transceivers use.
Ignore the internet (and WSJT-X) advice which tells you to adjust the
power with the audio level and set the power to maximum.
With Elecraft gear, set the audio as instructed in the manual and adjust
the power with the POWER knob.

Adjusting power still has me stymied. Oddly, once set and TXing WSJT-X FT8
15sec cycles, it creeps up from 180-200W on the KPA500 readout towards 270W.
The P3TXMON reads lower but creeps up over 200W on successive TX cycles as
well.
