[Elecraft] K2 40-Meter Transmitter Alignment

[edwin.ebert]

Hello
My K2 is in the phase of alignment and Test, Part III.
In the transmitter alignment with 2, 5 or 10 watts I have the voltage and
current similar to the manual (10 watts 11.5v and 1.98 amp).
Test Setup: 100w dummy and WM-2 Wattmeter from oak hills
Everything seems OK. Power and current remain stable during the tuning time
(5-10 sec).
But then I have realized that I have differences in the reading of the power
level before and after I push the TUNE Button.
E.g.: Power Set: 5 Watt then TUNE and the Display shows 6.3 Watt! 
Problem: If I repeat this procedure 10 times I read different, but stable
values between 4.8 and 7.1 Watt. The Wattmeter shows the same values as the
display.
If the Power Setup is 10 watts the display can go to 13/14 Watt with a
current that is higher as 2A (but not excessive),  that means CAL CUR (2.5A)
occur.

I think there is something wrong, but I didn't found this behavior in the
troubleshooting section.

Can you help me?

Many thanks
Edi, HB9BQJ
