[RFI] Switching Power Supply test Video

>"1) there's no information about antennas in use, or how close they were to
the shack. 

And that's probably the most influential factor.  The proximity of the SMPS
to antennas, lines, and equipment mean everything.  We often hear/see
reports that "brand X" supply is quiet and produces no hash.   That
statement may only be true in that one installation.  We all have different
installations that can have a profound effect on the degree of SMPS
interference.   
Meaningful results require thorough EMC testing, using regulatory and
industry-standard testing methodology.
