I've noticed a bit of the same thing on my K3S. Not an issue but I
view as a nice safety feature preventing overshoot and over drive of my
KPA500.

Hi Martin,
The power ramp up is normal behavior. The K2 uses requested power
control (Page 92, "Requested vs. Actual Power:" paragraph)
With a per band set value (Page 111, "Microcontroller" paragraph, "ALC,
which is used on CW to maintain the user-specified power level across
all bands.")
When changing bands, the output power is sampled by the microcontroller
resulting with a change in the transmitter ALC to increase power. The
ALC action requires a few dits or TUNE to complete.

After a band change the first dit, or two, is not at full power.
There seems to be an initial ramp up after which all is good and I don't
see any fluctuation in power. Supply is 13.5 volts when producing full
power, about 13.9 with just the receiver running. Full power current on
28Mhz is showing on the display as 2.66A. I can see the ramp up on the
bar graph, it shows one bar for the first 3-4 dots then ramps up to all
10 bars. I have confirmed the same with an external power meter.
Anything I can do about this?
