Well, I have tried everything. I have grounded the dish to the grounding block outside (which grounds to the grounding rod within a few inches), ran the coax through the Furman line conditioner, and even took the HDMI straight to the TV, while using optical audio. The hum goes through the TV and then back to the pre-amp, causing hum. Basically, if I hook up the DTV receiver in any way, I get hum. Anybody got any info on this problem?
