Hey John:
I had a similar problem with my KX1. It ended up being a bad solder
joint on a resistor pack. I cannot remember which one, but if you look
at the schematic
you will be able to locate it. After applying a little heat to the joint
all was OK. Hope this helps in some way.

I recently finished my KX-1 and installed the ATU board only to find that my
ouput is only about 0.9 watts on 40 and 0.2 on 20. When I finished the basic
KX-1, I put it on an uncalibrated QRP wattmeter and it read about 2 watts, so I
thought I was in the ballpark. Now, assuming that my original 2 watt reading is
really 0.9, I find that the output is the same both with and without the ATU,
so the problem must be in the transmitter and not the ATU.
The KX-1 checked out fine through stages 1 and 2 and the resistance readings
for stage 3 were all OK. I just checked the voltages on Q4, Q5 and Q6 and they
are within 10% of the table. I've checked the continuity for all the toroids
and T1, as well and recounting the turns and lead placement. The output
control is fully clockwise and the output is being fed into a 50 ohm dummy load.
All control functions appear to be working correctly and the receiver seems to be normal on all the bands.
I'm at a loss and could use a healthy does of "elecraft mojo"
Thanks,
John
