I think that the point he was trying to make is that when the source of the RFI
is found, we kind of know what it is.
While I think that an experienced troubleshooter might get some advantage in
hearing a noise, then having some good idea to look for it, an inexperienced
person might accidentally create a red herring, a false lead. That might take
up more time and effort than simply DF'ing the noise, and then knowing for sure
what it was.
Coming up - and not directed toward anyone in particular - just an observation
on troubleshooting.
Troubleshooting skilz are an interesting thing. The idea is to find and fix the
problem. That sounds obvious, of course. But I've found that many people at
some level want to be "right". This gets in the way of fixing the problem,
because the person thinks what they think the problem might be, then goes about
trying to prove that what they thought the problem was, was the problem. I
don't care, I want to fix the problem. Clear the mind, and try to fit the
symptoms to the problem, not fit the problem to the symptoms. There is a subtle
and critical difference. I've walked into many rooms where people tell me what
they think the problem is. A few occasions I've had to ask them to shush a
moment, because if what they thought the problem was indeed the problem, they
would have had it fixed by then.
