Hi Bruce,

A couple of questions. Did your test setup include exposed parallel wire 
cordage on the 120V line powering the bulbs that approximates wiring in 
a typical residence? Did your procedures include observation of 
radiation from that portable cordage? Did you look at spectrum below 30 
MHz?
