Thanks to everyone who answered this both private and public. To recap, 
I'm using the internal 2m transverter K144XV and trying to reduce the 
output on 2m below 1W whilst keeping the max of 10W.  I conclude:

    * the 2m internal tvtr cannot be adjusted to produce both 10W out
      max and 1W out min
    * this is a generic issue, not specific to my K3, and not due to
      oscillation or other fault
    * it would be preferable to integrate the 2m tvtr and control it by
      measuring the power out as per other bands but this probably
      requires a hardware change
    * the issue has been around for a couple of years without resolution
    * users will have to find work-arounds, probably in external circuitry
