[Elecraft] K2 output @2W

[Steve Hostetler]

I am trying to use my K2 to drive a little HFPacker amp I built.  The 
amp needs 2-2.5W input, but I am having trouble setting the K2 output.  
For requested levels around 2W, I get 1.5-1.7W as measured by both 
internal and external wattmeters and a simple RF voltage probe.  This is 
into both a good dummy load and the packer using key down and CALP.  My 
K1 is spot on with output into the amp.  When I increase the requested 
power to 2.2-2.5 W, power out jumps to 3-3.6W, so I am unable to get 2 
to 2.5W.  Above and below this range, the requested vs actual output is 
fine.  I've read most of the archives about requested vs actual power, 
but I didn't find anything about too much output at low requested 
levels.  So before digging into this, I thought someone might have some 
ideas about the problem, if it actually is a problem.

Thanks,
