Edi,
Nothing is wrong. The K2 does not control power as tightly during a TUNE
operation as during normal keying.

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
