Re: Thinking of selling FDM-S2 and getting DUO-R

I use self-adhesive copper tape stuck to the back of the monitor, with holes for ventilation, then I solder wires to the tape and connect that to ground. The power lead has eight turns through a toroid. The signal lead is wrapped with aluminium foil along with a drain wire, then that is taped to the lead and grounded. All grounds are taken to a single point. I also have lots of ferrite clamps, but they don't seem to help much. On the PC case, I have fitted additional bonding wires to ensure the PC case is solidly connected to the chassis. It is a newver-ending battle against noise.toggle quoted messageShow quoted text
The 2 inch copper tape I use is designed to repel slugs and snails to stop them climbing the sides of plant containers.
