Which shows how inaccurate English can be as a language - Rich means one
thing,
I mean another, and we are both correct within our meanings. But if we
talk about
amateur radio linears IN GENERAL on this reflector, then we also need to
consider
solid state wideband amplifiers in our discussions( anathema as they may
be to
some of us - me included!) , and then non-coherency etc (Rich's
definition) is applicable.
