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.
