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

when I transmit in SSB I am not able to get 100 % HF output.
peak power is around 40 Watts whatever I do, reading on the LP-100 peak
power meter. (using a Heil Proset with HC 5 Element) RF display is about
40 % max.
But! when I key the transceiver with the CW paddle in SSB (new feature,
very welcome!) I suddenly get full output also with normal speech.
If I twist the power a little up or down, I am back on 40 % output, with
one Dit in CW I can have the full power back.
Have you tried doing power calibration on all bands as described in the
manual? 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. This is more
accurate than setting the POWER control, which at present uses a lookup
table to determine the approximate drive value required.
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
