Telamon,

Being Well Grounded is the Best Foundation for Every Radio Shack

The Third Wire in the AC Power Cord is by-design an "AC Power
Return Path" -not- and RF Signal Ground Path.

Current Three Wire 'design' is for the delivery of AC Power.

All three Wires are usually just 1/16" Multi-Stranded Copper Wire.

A better Three Wire 'design' is for the delivery of AC Power
to RF Signal Processing Equipment would be :
(H)(R) 1/8" Multi-Stranded Copper Wire
[===] Flat 1/4" Wide by 1/16" Thick Copper Webbing for RF Ground

=== 1/2" Wide by 1/32" Thick

B U T ! - Until then a Second Ground Wire that is by-design an
RF Signal Ground is recommended for most if not all equipment
in the Radio Shack - IHMO

The use of a Flat Webbed Cable or Copper Strap from the Radio
Shack's Ground to the Receiver is by-design specifically to create
an RF Signal Ground Path for that piece of equipment.

Ideally there is an RF Ground Window leading into the Radio Shack
and Everything is "TIED" into it to Create :

The Common RF Ground Radio Shack.
= The Zero Potential Radio Shack.
= The Noise Free Radio Shack.

NOTE - The RF Ground Window is 'tied' to a good earthen Ground Rod
that is Bonded to the House's own AC Power System.
