[Elecraft] KX1 power question

[Don Wilhelm]

Bernie,

First, check all the capacitor values in the Low Pass Filter area.  Then 
  count your turns on both L1 and L2 - count the number of turns that 
pass through the center of the core, counting on the outside may result 
in an error of 1 turn.

You can adjust the spacing of both L1 and L2 to achieve the proper power 
output relationship, but do check the capacitors and re-check your 
soldering in the LPF area.
