I suspect what is missed here is that the Eimac recomendations in spec
sheets, etc are strictly a guide line for competent users; there is
nothing that says this or that MUST be used. They give you the maximum
operational parameters and then it is up to the user. Real users call and
consult if they have a question. Hams just assume they can run everything
at the max and then whine later.

Only one person has continuously attempted that stunt on this reflector.

Ian explained the process from the engineering grunt to the final draft
very well. Cheers Ian...an excellent post.

Fringe level experts are probably the most suspect, especially when they
provide no proof for their ideas.

Again...a statement that needed saying Ian....and should be repeated
regularly.
I wholly support skepticism in any facet of life, but what I see on this
reflector is a few individuals without credentials who expect everyone to
accept their credo.....while condeming others.  Sounds like a formula
used by  bomb builders IMO.

Any REAL engineers, Eimac particularly, please make yourselves heard.
