The statement "I thought the per-band settings might go back to their
presets ..."
The misconception is that there are presets and there are NOT, the K3s
stores the last set power for that band/Amp Mode. The "presets" are the
last power setting the operator made either manually or via
software/macro based on the amplifier mode (OPER/STBY). IF you adjust
the K3s power then you changed the "preset" for the amplifier mode/Band .
Below is the response I got from Elecraft support on this issue, just
substitute operator for macro, I have edited to make the point.
de Dave K5MWR
Power Set/Per Band is activated at the time of a band change. If your
macro/*OPERATOR PWR ADJUST* runs after the band change, the
macro*/OPERATOR* dominates--and vice versa. (The last one rules, in
other words). Similarly, if the amplifier changes from STBY to OPER
after the macro*/OPERATOR* runs, the power will change to the stored
OPER power level.
Note that it is likely that if your macro*/OPERATOR* sets a power level,
that level will become the new default power for either the K3's STBY or
OPER transmit level, depending upon which mode the K3/amplifier is at
the time the macro*/OPERATOR* runs. To use even more words (hi), if the
amp is in OPER on 20m and you run a macro*/OPERATOR* setting TX power to
75W, that will be the stored power level--whether you transmit or not.
The next time the K3 is on 20m and the amplifier is switched to OPER
mode, the K3 will return to that last-used AMP = OPER mode power level
of 75 W. (And the amp will throw an overdrive fault when you transmit).

All:
I purchased the AUX cable for the K3S / KPA500 to use the per-band
power option so the drive levels would stay put when the amp was in
operation.
After setting the proper drive level for each band, I noticed that the
settings I chose were lost if I turned the power up on the K3S.
I thought the per-band settings might go back to their presets if I
cycled the KPA500 from operate to standby and back, but that didn't work.
If the per-band drive levels are easily bypassed, it defeats the whole
purpose of having this option.
Am I missing something?
