I put the passive coupler in my box with a pair of dedicated curcuit breakers and it was an immediate improvement. But the biggest was finding out another pair of computers were still the signal suckers I didn't suspect. I am up to 4 of the XPPF filters and that improved the system quite a bit more.
My biggest issue now is still RF reception to a sticky switch, and I need another pre-amp to my BX24-AHT and to stop procrastinating and run a line into the attic for the silly thing!
