Al,
You will have to remove the ATU. Install the jumper in band board J8
between pins 1 and 8.
If your K1 does not have a "K1/ATU" switch next to the BNC jack, you
will have to re-install R36 on the bottom of the board - it should have
been left with one leg still soldered.
The lack of R36 connection is likely what is causing the difference
between the OUT parameter and the actual power out.
Be certain you connect a dummy load - do not use an antenna.

I want to realign the output of my K1, the radio has an internal antenna
tuner. The reason is because I check the radio is not coming out with the
proper power (test performed with dummy load and PWR-SWR meter Daiwa). "OUT"
is at 2.0W, and I can see, on the power meter, 1W.
I proceeded by removing the antenna tunner module, to be able to access L1,
... L6 (filter board for 40/20 mts band). However after this, when I try to
calibrate the RF filters, I can only get 0.1 W when I put the K1 in tune
mode. I check again the "OUT", and I stay 2W.
If I reinstall the internal antenna tuner, the radio returns to the initial
behavior (only 1W when "OUT" has been set to 2.0W).
Can someone guide me on how I should perform the power realignment process?.
