Henry Ott is a highly respected EMC engineer, consultant to many of the 
largest US corporations, and author of THE most highly regarded text on 
EMC. Henry is also a ham. I don't remember his call.

I do NOT recommend buying a noisy product and adding a filter, no matter 
how good it is. Some noise is radiated by products, and no filter will 
reduce that component of noise. And depending on how good the filter is 
and how it is connected to the noisy box, it may not be effective.
