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.

Hi folks. I'm finishing a new K2 for a friend. When I tried to perform the 40m Tx alignment, I instantly get "HI Cur" and the power drops to zero. 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.
I've got the little RF probe built. could someone point me in the right direction as to where to look for the problem?
Thank you verrrrrry much!
