Philip,
Thanks for noticing this. I switched the wires and confirmed that things are correct by tracing the circuit and comparing it to the original uBITX wireup doc. (Shows mid-vol going to wiper).
Question, on S-meter hookup.? I am using one of the KD8CEC "simple analog" meters and he shows the input to the op-amp (pin3? "In+") input from Vol Hi...
When you switched the two wires, did you also move the input wire for the sensor so that it was still with Vol high? Seems strange that the sensor is picking its input off of Vol Hi since that will vary with position of the pot. It would "seem" like the input should be the center wiper ("Mid Vol").
