Hey guys I'm looking for some help on an issue I've had since I got my Hopper system last year. I'm in the Cayman Islands and I'm looking at the eastern arc, 61.5, 72.7, and 77. Going to a DP44 switch, then to a Solo Node. I've switched all of my cables, but the 3rd tuner loses signal from 61.5, and 77. Has anyone else experienced this issue, or knows how to resolve it?
