k3 and power out on wattmeter

haircutter@verizon.net
Here I am using the K3 with the KPA500 and P3. Everything works great. But I have notice that when I am using the 2.7 filter and cw, and the  power set on the K3 is 80 watts, the watt meter on the Kpa shows 60 watts. If use the 500hz filter (on the K3) the kpa watt meter shows 80 watts. Also notice that if I have the cw pitch set above 400hz the correct watts show on the watt meter. But if I set the pitch to about 350 where Ilike it, it shows a drop in power output on the meter. (60 w)
 Did the "ref cal" with wwv and calibrated the watt meter through the menu. Can anyone tell me why this is happaning?
