Corona causes RF noise for sure. But RF noise also occurs in
the complete absence of corona. RF noise in the complete absence
of corona is what we have been discussing. *Nobody* is arguing that
corona doesn't cause RF noise. We are arguing that RF noise can be
caused by something other than corona.

Cecil,

How do you know there is no corona discharge? Is there some special test
that tells one if corona discharge is present or not?
