Edited title and body to clarify the question

| Oct 11, 2014 at 21:01 | comment | added | Chris Cirefice | @pjc50 I've already read that question, but there is a primary difference between mine and theirs - I only pick up radio signals when I touch the device, specifically the volume knob. I know from that question that it's receiving radio waves arbitrarily, but why they feed back when I touch a specific knob is what I'm interested in. I edited the title and question body to make this more clear. | |
