[Elecraft] Hi Cur error on alignment part III, even at QRPp. 40m only. Rx is good.

Larry,

If it only happens on 40 meters you have some problem with the 40 meter 
Low Pass Filter.
Look at the schematic for RF Board sheet 3 toward the lower right and 
you will see the components associated with the 40/60 meter LPF - check 
them all for proper values, correct turns on toroids, good soldering, 
etc.  Include relay K12 as well.

73,

This happens if the output power is set to anything above 0.3 watts. This only happens on 40 meters. I was able to peak the output on all the other bands normally.  The Cal Cur is set to 2.5.
