[TCML] RF Ground and Brass

[Lau, Gary]

Perhaps it's not really rocket science to gauge the peak magnitude of mains hash.  I'll also try employing a simple R-C high-pass filter between my mains wires and a large counterpoise reference ground plate (sheet of Al foil) on my concrete basement floor, and seeing at what input level my scope triggers at, with the various secondary grounding schemes.
