It seems that there is allot of RF pollution in the home environment as people move away from wired connections. Any audio device close to a transmitter can cause interference. I did had some issues with cables picking up RF signals cause a sort of overload that spilled into the audio range of the device. I use ferrite cokes on the cables and correct placement of wireless devices can do much to reduce interference. In the old tube TVs there were metal shields on some tubes to protect them from other tubes and the strong magnetic fields on the main picture tube that can generate interference with some tubes. Driver tubes or the pre-amp tubes are more likely to pick up interference than power tubes because of the gain factor.
