Since Monday morning I lost one of my OTA channels (RF22). It used to be the strongest one. All the other channels I still receive with the same strength. I have a CM3020 with a CM7775 amp connected to a ViP622. My old voom receiver has the same issues. The voom shows about 60% signal, and needs at least 80 to lock. The ViP622 shows no signal at all. Is my amp broke or would all channels be bad then? Or is it the station having trouble? I am 75+ miles from the towers and all stations are about 2 degrees apart.
