[Elecraft] KPA100 Problem

[Jim Stoneback]

Dealing with the last unresolved problem with my K2/100:

When using the K2/KPA100 on CW, regardless of power setting (above 11 watts, 
that is), the power output fluctuates above the set power level by about 
10%.  With the power setting at 90 watts, the output will alternate between 
about 98 and 88 watts, at about one cycle per 2 seconds.  At 30 watts, its 
+/- about 4 watts, etc. Using a dummy load.  It will do this indefinitely.

All other aspects of the KPA100 operation are normal.  With PA turned OFF in 
the menu, the barefoot K2 does not exhibit this power fluctuation.  Any 
suggestions on what to look at?
