I was just thinking about posting the same link. Jim Brown offers quite a bit of expertise on the subject of interference, with this and other publications. He may get a bit "technical" for some people's tastes, but I've never seen him include any smoke, mirrors, or snake oil (cryogenic or not) in his work.
As for the speaker leads, leave them connected, but turn the amp's power off, and see if you hear a "peep" out of the speakers. If not, try connecting one cable at a time, and see where you start to hear the interference. You may have a loop of some kind that is resonant to the station's frequency, or maybe (not unheard of) a bad solder joint in a connector.
