W4AN GA was fair copy to KS around 1700 UTC. I suspect the daytime 160M 
prop. is related to decreased D-layer ionization due to the lower solar 
angle in the winter.  WLW 700 Cinncy, OH, WBBM 780 and WLS 890 Chicago, IL 
have had good daytime signals the last 2 weeks. Probably notice the daytime 
prop. in the contest as high power big antenna amateur 160M stations operate 
in the daytime.
