I don't get any errors w/r/t analog signals. I just tried checking all 4 inputs and still got nothing.
I'm wondering if it's somehow related to my settings on the SCT device itself. As I said, I can read the A/F from the handheld when I "start monitor" so I know it's getting signal. It's apparently problematic somewhere between the handheld and the laptop.
Who by worrying can add a single hour to his life?
