At the risk of appearing "thick" (not the 1st time :-o), I finished putting together the KAT2 antenna tuner, but with a leftover component: R6. I know where it goes on the board, but I must have missed where in the instructions it said to install it. Have I missed a step or is R6 only installed with the use of certain additional options?
