[Elecraft] KAT 100 Resistance Checks

[Chuck Gehring]

I am building the KAT 100, the Resistance checks look fine except for U2 Pin
12 shows some resistance and then a short to ground.  I have gone back and
checked for solder bridges.  I have checked the reflector for previous
posts.   I don't have U1 installed and the schematic shows pin 12 connecting
to Pin 12 of U3, U4 and RYLoad.

Any recommendations
