In which direction is the downward tilt at sunrise -- east or west? 
Logic tells me that the downward tilt would be to the east (the direction
of the sun), meaning the first hop distance would be greater for a
high-angle signal, but with little (if any) effect for a low-angle
signal, yet I normally see enhancement of received signals west of my
longitude at sunrise with my vertical antenna.   Or am I all wet?
