 From my measurements, the IMD of both the K3 100W PA and the 10W amp 
improve by around 10 dB at 1/4 power. In my shack running the K3 at 20 ~ 
25 Watts works very well into an Acom 1000 linear for the UK power limit 
of 400 Watts.

--------------------------------
"Squeezing higher power out degrades the IMD."

SO... The "10 watt" amp feeds the 100 w PA? Does it get fed with 10 watts
or 12 watts? What does that mean to the IMD of the 100 w PA by the cause of
the degraded IMD being fed into the PA?
