Found this on PFM on a RFI thread that will probable end up following the usual track. Brief read it seems interesting I thought especially for Nigel and John. I would love to have an understanding of grounding/design of electronic circuits but that will have to wait until I am reborn. Two guys on the PFM thread seem to work in that industry I am hoping they explore this.
