Thanks, everyone, for weighing in. I’m armed with $95 of ferrite snap ons and chokes and two MFJ heavy duty AC filters! Saturday I plan to carefully re-design all of the AC wiring in my office/shack which is, admittedly, a hodgepodge of extension cords and power strips with at least 5 wall warts. I suspect the offending switching PS runs the brand new LG display used with the K3S SVGA. It’s a small, light little thing. Runs very hot. Most likely will be replacing it with a linear wall wart or something cleaner. I found this article that explains the differences between linear and switching power supplies: http://www.clever4hire.com/special-articles/home/ac-dc-power-supplies---using-wall-warts
