I suspect it is because that is the condition for which research has been
documented. NTIA identified
skywave propagation as an issue and said that a serious study of it was needed
during the next phase of
their work.
ARRL has focused on the scientific approach -- i.e., that which can be
documented and which cannot be
construed as "claims." Skywave interference studies are more computationally
intensive, as well as more
difficult to set up with actual systems. Further, small scale tests of skywave
would not be meaningful anyway
-- it is the accumulated noise of MANY sources that will cause major problems
at distant locations, and large
scale tests have not (AFAIK) been done. NTIA's work is solid science, and to
the extent that it covers it,
tends to back up ARRL's earlier comments.
