John, You apparently have a short in the KPA100, most likely on the 12CTRL line.
You can find this line on the schematic entering the KAT100 at J3 pin 8. Follow the line to determine what other points it connects to and check them all until you find the short. I do not know what the resistance to ground should really be on this line, but it certinly must be significantly higher than zero. 73, Don W3FPR > -----Original Message----- > > I am attempting to use the KAT100 for the first time and a new > homebrew G5RV. > > Just finished the cabling and went successfully thru calibration > steps.
