The W3AFM series was interesting in its time, but pretty rudimentary by today's
standard. One of the commonplace things in those days was to equate DXing with
contesting. This notion of "layers" of stations is insupportable, when you
think about it - no way 1000 or 2000 QSOs in a contest could be sorted into
discrete layers by signal strength. I think it is inarguable, though, that any
increase in either the strength of your signal or your ability to hear other
stations will increase the number of stations you work in a contest period.
How large an increase before it makes 1 QSO's difference? I have no idea.
