Radio Propagation Forecast

 

Radio Waves reflect and/or refract through the upper layers of the earth’s atmosphere, more specifically the ionosphere. That’s why you can hear radio stations from far over the horizon. The science is called Radio Propagation involving many variables such as time of day, frequency and sun spots just to name a few. This widget is great info at a glance for anyone interested in Amateur Radio or Shortwave Listening.
