[Elecraft] KX1 power output question

I am in the final stages of testing and allignment of my KX1
With R4 fully clockwise
I plugged in an Elecraft Dummy Load and a DMM on the power tap
I plugged in a 4 Ahr battery
I selected TUNE
The loaded voltage of the battery is approx 12.45V
The draw is 350mA from the battery
The dummy load tap only indicates (after calculation) 2.24W on 20m and 2.02W on
40m
But the manual says I should get 3-4W
Every test up to this point has been within spec
I cheched ALL the voltages on the chart which were in spec
I checked ALL the toroid coils and the toroid transformer and all read 0.0ohms
from pad to pad
The only suspicions I have at this point are:
1) the battery is not running a full charge (13.8V), so I put it on charge
before I left for work and will try again when I get home
2) maybe I am not getting a good voltage reading at the voltage tap on the
dummy load, so I bought a BNC-UHF adapter to see what my RS watt meter says
tonight
Does anyone else have any ideas/suspicions/suggestions?
