Unless you have a 1-radio "station" and no lightning protection of any kind, this is a very bad choice. The dedicated power outlet for the COMPUTER is wired by the electrician so that both ground leads (white and green) are wired directly to the breaker panel. The power and ground is NOT looped to other outlets. It is a dedicated power (and ground) outlet for computer use only. It is typically an orange colored power outlet. This was not intended for radio use. It is simply suggested to keep radio equipment powered on a separate power circuit from the computer with the computer ground going directly to the breaker panel ground. That IS the single point ground for the house power wiring - at the breaker panel. Our discussion here is about radio, and that is not a helpful or cost effective modification to make. Neither does it provide separate power to the computer as you allege, it is merely a dedicated neutral and ground connection to the mains. If electrical planning or mods are being done, much better to provide the radio room with its own branch panel. Having a computer on the radio circuit is not a problem, having the whole house on the radio power loop can be. Your description of single point ground for the home wiring is correct, but not complete. The radio station has its own single point ground, and all AC equipment in a radio room must bond to that. Equipment bonding in the radio room would immediately negate the questionable benefit that a dedicated computer neutral/ground offered. One grounding electrode conductor from the station single point ground to the AC mains single point ground is required. This creates an unavoidable loop, which is why truly separate power to the radio room is desired, not a useless dedicated ground for a single piece of equipment. The one noisy dimmer switch I have in my dining room, no longer affects the radios since providing separate power to them. Jack TL & JP, I you're going to have an Electrician (or a DIY Job) do all this work of putting in a 'separate' Circuit for either the Computer Equipment or the Shack Equipment. - Have him (you) install a a Double Outlet Metal Box with two sets of Two Outlet Connectors. - Plug individual devises into the individual outlets and do not daisy-chain the electrical connections. - Use individual Clamp-On Ferrite Cores on each Electrical Power Cord 'near' the Devise-End of the Power Cord. TIP: Use enough Electrical Wire so he (you) can Install an Individual Ferrite Core on each of the Three Electrical Service Wires. Use a Toroidal and wrap 3-4 Turns looped through it. - The same can be done on the ends of the Wires that are inside of the Main Electrical Service Panel-Box. - The object is to keep any and all the household electrical wiring from becoming Noise RFI/EMF Radiators (Antennas). - The same can be done with Dimmer Switches. TIP: Have the Power Company 'do' an Inspection of the Electrical Service Entry to House. - Have them Verify that you have a Eight Foot or longer Ground Rod as your Primary Grounding Point for your household Electrical System. - If you do not have one; then have one Installed and properly connected to you Electrical System as your Service Entry Primary Grounding Point. - If you 'feel' that you need an extra/additional Ground for your "Shack". Then have one installed with a "OO" Copper Wire if less-than 20 Feet and "OOO" Wire Copper Wire if more-than 25 Feet distance between it and the Service Entry Ground to 'Bond-them-Together'.
