If you listen to AM radio stations at night that are just impossible to pick up during the day, chances are you’re benefiting from sky-wave propagation. Propagation is just the technical word for how radio signals travel through the air. Sky-wave propagation is the specific name given to radio waves that travel through the sky. Sky-wave propagation takes place between sunset and sunrise. It’s the flip side to the ground wave propagation used to transmit during the day.
During the day, ground wave propagation is preferable because the radiation from the sun causes so much ionization that radio signals sent into the air are absorbed into the atmosphere. When atoms in the D region of the ionosphere are ionized, you end up with free electrons and ions floating around in the air. It’s kind of like trying to walk through a room filled with dancing couples…..
