Many times the band peaks far off sunrise or sunset, and goes 
downhill. Never wait or depend on the sunrise/sunset peak!

For example, there are many days when the path to VK peaks 
neither at their sunset or my sunrise. The same is true for JA's and 
everywhere else where the path is over a few thousand km.

I've never experienced "one-way propagation" on 160 without noise, 
QRM, or the radiated power on one end of the path easily 
explaining it. 

"One way propagation" is especially likely to occur in contests 
because of QRM and the fact operators are listening in multiple 
directions and may miss calls. It is tough enough to tune the 
receiver up and down a bit in frequency and check all directions 
and antennas on normal days, let alone during a contest!
