Could it not be that sunrise enhancement also occurs every morning 
even at inland locations, but if the maximum signal is still below 
the ambient noise (splatter etc.), then it wouldn't be 
noticed?   More study is needed, but I'll bet that a Seattle DXer 
with a Perseus and a simple antenna could set up and record a 1 Hertz 
wide window on, say, 594kHz through a marker.log file, to see if 
there is blip near sunrise, even when the die hard DXers are saying 
that they should have stayed in bed.


best wishes,
