Have you tried calibrating the inbound levels using the front panel value quality display and the true Sinad values? I've found the numerical value assigned to the input signal is not a linear relationship to the signal to noise ratio. You can set the input signal bench mark at user selected values for your choice of SN ratio. > That aside, I suspect that using the COR, as recommended, > helps facilitate the voter's operation.

The good part about the LDG voter is you can easily disable unwanted links in hardware and software. > As a suggestion, you can install PL boards on each > of the feeds and use their decode detect to signal > the voter.

I had not found the control access to be a problem.
