After my last article‘s mission of discovery I set about trying to stop the rPi Official 7″ Touchscreen from interfering with my 2-way radio. It looked like the LCD ribbon cable was broadcasting spurs every ~1MHz or so right through the VHF range. I acquired some adhesive copper tape thinking I could shield the cable to prevent the noise from escaping.
The copper tape arrived, and despite wrapping the LCD ribbon cable and grounding the copper tape it failed to provide any shielding benefit. Nuts. So what else can I try?
