Is it pointless or a good idea to use ferrite cores on the earthing wires in the shack?

Thanks in advance.

Ferrite cores should always be used, but not on the ground lines. You need them on feedlines both near the antenna and near the radio. Power lines, both AC and DC.

I have ordered them in bulk (Mix 31 and Mix 43). It was after reading http://www.yccc.org/Articles/W1HIS/Co...
that made me a believer in RF Choking.

The quieter you are, the more you can hear.

It's actually counterproductive to put ferrites on the earthing wires as you want the RFto go to ground.
