One might add also that skywave propagation favors longer paths during 
periods of minimal sunspot activity such as we're having now.

At least that's my experience here in Quincy when listening to the Chicago 
Class A stations well after dark.  From 225 miles, nighttime WBBM normally 
is noise-free on an indoor radio here, when sunspot activity is high.  Right 
now they can have fairly long periods of co-channel interference from a 
Spanish-language station.

It might be that these periods of several years of low sunspot activity are 
the reason why people can think the performance of Class A stations is "not 
what it used to be," even though their ERP has not changed,
