And it is almost the same here in Europe at 35-55N.
In general we start to hear stations to the East at least 1 hour befor
sunset, but it is hard to get throw.
Same from Balkans to EuRus and AsRus.
>From Cyprus to AsRus.
And from EuRus to AsRus and further to Deep Asia and Pacific.
Much is contributed by the fact that not to many people switches their RX
Antennas to the West, which is still in daylight ...
My guess is that this mistake first and much stronger noise level propagated
in the areas which is in darkness, makes such a QSO difficult.
