That is only part of it. I read somewhere (ON4UN's book?) that signals can
leak from darkness (night) into daylight (sunset) areas. However, getting
the angle right from the daylight area to ENTER darkness is a problem, as
well as the additional attenuation. Bottom line being - you can hear stuff
arriving from the dark, but will have a tough time sending signals back.
Maybe someone else has a better explanation / reference for this.
