The resetting of power upon BAND change is a function of the ALC which
is NOT hardware-derived, but software-driven. When you change bands, and
the power level generally WILL change because each band has a little bit
different efficiency, hence different drive levels required for the same
requested power output, the ALC must measure the actual output against
the requested output and make a determination as the drive required.
This requires a number of RF cycles to accomplish, thus the need to hit
a few DITs.
I find myself switching to the dummy load after changing bands and
sending a string (not a couple) of dits. This is very annoying in a
contest or when calling a DX station, but as you say it is inherent in
the design of the K2 and it doesn't seem that there's anything that can
be done about it.
On the other hand, Wayne has worked apparent miracles before, so maybe
he can again!
