Interestingly, no one except Vic said anything about the antennae they're using. And he has a directional yagi that's well away from his locally generated rfi. So if you're using a dipole FM antenna in the same room as your digital gear, what do you expect?
That said, a lot of rfi can be dumped into your power lines by the PC on the digital equipment -- shielded PCs help keep it from broadcasting into the air but not from contaminating the house wiring itself. Using a conditioner or regenerator with digitally filtered outlets can keep this from becoming a problem -- and eliminates the necessity of plugging the digital gear into a separate circuit.
