[RFI] How far does RFI travel?

While extreme, the last example should be adequate proof that there is no
predicting how far RFI CAN or will travel.
I categorize this question in the same manner I categorize questions about
what a source might be by the recorded sound of the source. That is,
speculation about the nature of a source may be entertaining but it serves
no other useful purpose.

Each case is unique just like every other case. Time is best spent choosing
the best method for locating the source followed by actually locating the
source. Whether the source is 100 feet or 100 miles away, once it is found
all questions will be answered.

For the billionth time: RFI is not pinpointed with eyes or ears alone. Good
equipment ("tools") coupled with proper interpretation of the data provided
by the equipment will lead the investigator to the source. Guessing what a
source might be or how far away it might be is a fruitless waste of time.

It is my opinion that the primary message here should be: *Find it first.*
The answers will then be apparent.
