Better yet, just bond each piece of equipment to the station power supply ground terminal. Don't bother with big flexible ground straps or a copper buss bar across the back of the desk. Make some nice flexible bonding jumpers using #10 AWG auto primary wire with suitable ring connectors attached. One per piece of equipment connected to the station power supply ground terminal.
As to an outside driven ground, yes it MUST be bonded outside of the structure to the AC mains ground. If this is not done, you have a very dangerous system, highly prone to damage in the event of even a nearby lightning strike.
Depending on your antenna system, a station ground is not needed, except for lightning protection equipment which should be outside of the house. That's the way and why the driven ground is used.
If you have a Common Mode Current issue, it is RF being picked up by the feedline acting as an antenna. Common Mode Chokes at the antenna feed point and at the station end of the coax will most likely resolve the issue.
It is much better to find, identify and correct the issue than to throw ferrite at everything, acting like a band-aid.
As to grounding, Bob Heil needs to study the work of Jim Brown, K9YC. He would find out just how incorrect his recommendations are. PLEASE do not follow Bob Heil's recommendations. It is dangerous.
