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.
