Bob,
Are you driving the audio level sufficiently? Inadequate audio drive is
a common cause of such 'power hunting'.
You can do this off the air - turn the power to zero or connect a dummy
load.
Then turn compression to zero.
Talk normally into the microphone and adjust the MIC GAIN to produce 5
to 7 bars on the ALC meter.
Now you can increase the compression to the desired level. 3 to 6 dB is
often suggested, but it is your choice.
After a band change, the initial power should be low, but should quickly
increase to the requested level after a few syllables.

I have a new KX3 with the up to date firmware, this radio is a replacement

When you go to 15Mtrs on USB from a different band the output power is very
low on the output meter on the radio, if you change to CW mode and send a
single ditt then go back to USB you get full output. The dealer thinks it is
a firmware problem just wondering if anyone else has the same thing
happening on there KX3
