Bernie,
First be certain you have adjusted R4 for full clockwise rotation - and
if you still have low power, yes, make the 2 resistor changes for the
KX1 power mod.

The only problem is that the power out with a 13.4V supply, as measured with
the DL1 dummy load, varies from 2.6W on 30m to 1.9W on 20m, so it is clearly
below specs. These values are within less than 10% of values from an analog
Daiwa power meter, so I think they are close to correct. So the question is,
should I change the two resistors? Is the extra watt on external or 1/2W on
internal power worth the risk of overdriving the output transistor?
