Guys, I'm stumped. I'm getting a spanish radio station blasting through my stereo on every input and in every speaker. There's a radio tower (AM, I think) that's about 500 yards from my house. I think narrowed it down to the speakers or speaker wire, but don't know what to do next.\n\nGear: Denon receiver, Polk Surrounds & Center, Canton Fronts\n\nSpeaker Wire I'm using\n\nSteps I've taken:\n\n\nEnsure the outlet I'm using is grounded\nTested with headphones. As I'm listening on my headphones, as soon as I start to unplug each speaker, the radio signal gets quieter and disappears when I unplug the last speaker cable.\nFerrite Rings on ever speaker cable and power cable. Didn't have any effect.\nShielding wire for the full length of a speaker cable. Didn't have any effect.\nCalled Denon. They just told me to reset the receiver and if that didn't work, then I need to send it in for servicing. Reset didn't do anything.\nWhen I turn on the "Eco" function on the receiver, the sound goes away (but that essentially just turns off the surround speakers).\nPlugged in the radio receiver that came with the Denon. No effect.\n\nAre there any experts out there that can help me before I throw everything away and buy a soundbar?
