Followup to KVM RFI: Possible solution fell off?Posted: October 6, 2010
I will probably find out otherwise when I make this post, but I may have resolved my KVM RFI problem. In a previous post, I performed a teardown of my KVM and noted that the top of the unit was blank. Normally there is a name plate on the unit:
I found this plate nearby—it had fallen off the KVM. I stuck it back on. (I wanted to re-glue it, but it would not come off the unit for me.) The “IOGEAR” logo looks almost metallic. I immediately wondered whether it had a shielding function. The plate appears to be plexiglass with perhaps a metallic layer in-between where the logo is etched.
I have had both machines hooked up to the KVM for a day now and have not seen the interference that has driven me nuts for nearly three months. I hope this is it. Really.
