It is well known to us who work in this field that the FCC noise limits for computing equipment are so loose that even if the equipment - with or without the wiring - meets the specs, there is still sufficient signal radiated to cause harmful interference. The law does require that the operator of the offending equipment cease operation if harmful interference is being caused, but this is a very delicate situation because in general the operator of the equipment does not have the technical savvy to understand why and how interference is being caused. If not handled correctly, the problem then escalates from a technical problem to a legal confrontation, which is never pleasant. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ARRL Volunteer Counsel -- Philip M.
