[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 7.1 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.

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
