In shortwave radio and broadcast AM radio, part of the signal travels thru Planet Earth. So a stake in the garden acts as part of the antenna. When a path to Planet Earth is not accessible, a 'counterpoise' is sometimes used. It would be an arrangement of wires or metal objects to act like Earth.
Preliminary DIY Grounding Box Result
I live in a big, downtown high rise building. Our grounding is crap. I just took a 12 awg sliver stranded wire and stripped both ends. One end went straight into the center of a 3 pound bag of magnetite, and the other stripped end was wrapped around a spare coax rca input (outside negative) on my DAC.
Result: Highly noticeable "analogue-ing" of the sound, along with more dramatically more pronounced soundstaging. Space between the instruments seems like it tripled. Smoother, detailed highs and warmer, dynamic vocals.
I have some quartz coming and will mix it in. Plus I’ll run to other components and report back. Just wanted to try this for a quick test.

A stake in your garden isn’t going to improve your AM radio reception. A radio station ground plane is part of its antenna system, but the signal doesn’t travel through "Planet Earth" on its way to you. And oddly, a radio station ground plane isn’t even necessarily connected to ground itself. |
