I am a shortwave radio listener and I use an external radio module that 
plugs into the laptop via USB port.  However, these switching supplies are 
making horrendous noise and harmonics all across most shortwave radio bands. 
I can reduce the noise a little bit by moving the supply to a different spot 
or winding the incoming/ outgoing power cords through chokes, but this still 
isn't enough.  The only alternative I could see was switching to a linear 
supply if one is still made for laptops.
