Happens on all bands. Relative to an external wattmeter the power the K2 shows is wrong and the power the KPA100 outputs in some cases is not ok. Max out on the lowbands is almost 150 watts and pulled current is above 20 amps. On 20m and above output is more normal, output is never above 100w. For example the K2 reads 80, but the external wattmeter reads 100w. On 15m output is below normal. The K2 will read 110 and the max out is 90w. Approachs normal at around 70w. On 10m ouptput tracks like 20m except max out is about 110w.
