[Elecraft] [K3] LPF DSP modification

[Don Wilhelm]

Just take the tip of a knife blade and cut a "V" notch through the PC 
board trace.  You do have to apply some pressure to the blade to get 
into the fiberglass material and through the solder mask.  Use whatever 
knife you are comfortable with, but it should be sharp.  I usually use a 
utility knife or my pocket knife.  Do make sure it is sharp, a dull 
knife can slip when pressure is applied, and we don't want any injuries.
