I've got a situation where I have an X-10 Lamp module plugged in near my stereo. If the X-10 is in the ON or Dimmed state I cannot tune any AM radio stations - all I get is noise. Turn X-10 module off and it works fine. Other than removing the lamp to another area of the room or moving the X-10 module to a different circuit, neither of which are practical due to the physical setup of the room, is their any cure for this?
Are X-10 modules inherently noisy and known to interfere with broadcast radio reception?

I've tried different lamp modules with the same result. The module I'm using is the standard X-10 LM465.
