Right at this minute, about 20 minutes after local sunset in
January, skywave is very subdued and WXKS is audible 25 miles
north of Wellington Circle.  A few weeks ago, due to a solar hiccup, there
was little difference between day and night (one person posted to
the New York city radio board that he could pick up Stamford's 
outlet at 1400 in the City!) and during that period, I could listen
to WXKS-AM easily in my home; even WJIB-am at 5 watts was
at least as audible as it would be during the day if the station's
switcher failed to boost to 250 watts at sunrise.  So it 
appears that WXKS-AM is legally putting out the equivalent of 
several hundred watts, or even a kilo due north,  NW and NNE...
yet it is still clobbered by WENE.  In the morning, when I'm on
route 128 north of Boston, I can pick up the two Marks AND
Imus on WENE simultaneously!  It's amazing that even Everett 
gets sufficient quieting!
