Andy,
That trace cut was not to be done on a new K1 RF board. You will have
to remove the resistors and capacitor and repair the trace cut with a
jumper wire. Check page 7 - the "i in a triangle" informational item
near the bottom of the page - it says to skip the next 5 steps if your
board is new.
I believe 'undoing' those 5 steps will restore things to normal.
73,

In the troubleshooting, guidance is to verify the orientation of U2 and D3. I verified they are correct. I also checked that D3 was still functional. I have checked and double-checked the solder work on U2, D3, and adjacent components. All look to be okay with no obvious shorts.

R4 was already installed in the space indicated by the silkscreen on the bottom of the board. So, I cut the trace and removed the OLD RF-R4 and reinstalled it, bridging the trace I cut. Is this correct?
