Re: Interesting "source" of RF interference

Ken Sejkora

Hi Kriss,


Yes, the extension cord did increase RFI when plugged into the wall outlet that the power strip is plugged into, but probably about 5 or 6 dBm lower than when plugged directly into the power strip.  I plugged the extension cord into several other wall outlets in the room that are fed off the same breaker, and there was always a small amount of RFI introduced, but levels were lower the farther away the wall outlet was.  Tomorrow I might try a different extension cord, as O guess it is possible there is some type of strange fault in the cord introducing noise, but I don’t think that’s the case.


Thanks again for the question.

Power Strip have any hardware inside for filtering, surge, etc?
What's the extension cord do when plugged into the same outlet the power strip is plugged into?
