Tom,

The information you have provided to the ham radio community has made you a legend.  Your web page is filled with good solid technical data.  You participate on this and other forums, contributing your specialized technical training and experience -- all gratus.  I thank you.  There are several other "greats" on this and other reflectors that contribute regularily on various topics related to their expertise.  I thank them too for their careful and respectful responses.

Several people responded to me privately after Jim's onerous and belittling post.  They responded direct to me (privately) because they are unwilling to expose themselves to the ridicule that often comes in response to publicly failing to use technical terms in an exacting way, failing to understand notions that can take a specialist years to grasp and master.  The fact that I do not understand surge impedances on random lines, the vagaries of various ferrite mixes, and the subtle nuances of EMI/RFI does not make me an idiot.  Ignorant maybe, but not an idiot.

If there is a solution to this COP problem, and I can figure it out on my own, in a vacuum, I will announce my findings so that others can attempt to replicate my results.

Thanks for the help.  I owe ya...
