hello all. just completed myKx1. Power output is only 3w on 40, 2w on 20 @
13.7v. Any suggestions on any additional output power? Is there an
adjustment for the output indicator in the Kx1. thanks..

First make sure trimmer pot R4 is fully CLOCKwise now.
Check the two inductors wound on yellow cores: L1 and L2. L1 should have 13
turns and L2 14 turns. It's easy to get them reversed!
Finally, while transmitting into a dummy load adjust the position of the
turns on L1 and L2 for best balance between 20 and 14 meter output. They
should be within 1/2 watt of each other, and can usually be closer. That
will often improve the overall output.
I am not aware of any adjustment for the output monitor in the KX1. The
KXAT1 ATU, which displays the power out in watts, is adjustable.
