Hi,

How about using the ground in a 3 prong electrical socket???? Better than
nothing??? Dangerous??? I'm in a high rise


In those circumstances, it's a crapshoot. Often connecting to a building
ground like that will add more noise than signal. If you do want to give it
a go, connect to the screw that holds the plate on, don't just stuff a wire
in the hole, as it can find it's way to the hot side.
