hi Wayne, to make a long story short - all ok now!! explanation between the lines:

You need to do TUNE on each band, into a dummy load, at both 5 W > and 50 W. This should get you reasonably close at 100 W. no I did not - until now. In the manual I misunderstood the first sentence of this chapter: "is normally done at assembly time or by the factory." So I skiped this step :-( I did it now - and it seemed to help. > However, for best initial power-setting accuracy in SSB modes and in > DATA A and AFSK A, I'd recommend doing a quick TUNE.

I limited the tune power to 8 Watts - my automatic tuner does not need more to tune. When I set Tuner power to normal, the output power I see on the wattmeter corresponds very well with the K3 setting. Another observation: the ATU problem seems to be solved now. I don't know how this is linked, but it seems to work now, when I set the 2.7 filter frequency offset to its correct value of -.89 thank you vy much, 73! de Werner OE9FWV -- Veni, Vedi, WeeWee: I came.
