[TenTec] RFI Issues

[Pa1ap]

I really like the document as shared and reading through it. Would appreciate your advice on the following rfi experience:

recently I build an artificial ground to ensure rfi gets directed somewhere else. I wasn't sure it would fix the rfi issue but figured it was fun to build and never harms... after connecting the artificial ground to the rig there was little rf going through the artificial ground which suprised me a bit. I also noticed touching the chassis of rig, balanced tuner, power supply and other components changed the current. Then I decided to decouple all wires connecting to the rig using ferriet cores. Suddenly the rf current through artificial ground went up and touching chassis of previous mentioned devices had little to none influence on the current through artificial ground. 

Now the orion seems very isolated from eveything except the artificial ground tuner. Rf through tuner is stable and when I am working on 20m and up there is no issue anymore with rfi into the house nor my computer speakers.  It was fun to learn something so fundamental and to realize I forgot more than I realized ;-)  yes I have a compromised shack as it resides at second floor of the house and I am almost touching the apex of my dipole. 

The question I have: could I have done this easier through applying other techniques like described in the document? am I just fixing a sympthom instead of the root cause? I had two rfi issues; potential rfi into the mic and rfi into the audio equipment within the house. I am new in this area. 

Thanks and best regards, onno
