My point is this: Jim wants people to stop using isolation circuits and
his "carrot" to them is simply to tell them to do it the "right way" and
the right way is to go study 66+ pages of technical material and to sort
it all out for yourself.
I really can't understand Jim's expectations when the alternative for
hams without an EE is to simply spend some money for the gizmo that
provides some kind of solution. It's not very helpful or understanding
of those hams who are not EEs to just throw a link at them. Being right
doesn't necessarily mean anyone is going to listen to you.
And, please, don't tell me that passing any multiple choice exam where
the entire question/answer pool is public is equivalent in any way to
real electronics knowledge.
