The complainant even provided the fix (Toroid cores, often seen as those lumps on USB cables) for free, installed and everything. In response the emitting neighbor went and... "You apparently discarded the toroid devices, tossing them in Mr. (deleted) yard. The devices were simple and non-intrusive, and we can envision no reason whatsoever for you not to continue using them, other than a desire to be uncooperative." Dabbling in RTL-SDR for a bit quickly brought me up against the interference monster, and since the USB sticks are typically powered by bus if no direct power modifications are done one of those sources of interference was hooked right into the receiver. Toroid cores either clipped on or looped were indeed the answer for quieting the cable. This doesn't help much if the interfering device is emitting really badly off the board itself though so manufactures shielding their devices as a standard is rather welcome.
