Web30 jul. 2002 · Radio signals from 1-50 MHz often bounce from earth to ionosphere and back, and often several times to get to your radio. That signal may be not propagating well via ground-wave to your current location, and the skywaves are effectively bouncing right over your head. Here are a few links to get you started: WebThe Ionosphere. Regions of the ionosphere, showing the D, E, and F layers. Earth's atmosphere contains a series of regions that have a relatively large number of electrically charged atoms and molecules. As a group, these regions are collectively called the ionosphere.

The deviation of the ionosphere from the quiet values (median) are considered as …

WebHF radio signals are propagated via ionospheric transmission, with transceiver devices emitting sky waves directly towards the atmosphere. These signals bounce off the layer of gases and back to Earth’s surface, to be picked up by a receiver. VHF ground waves, meanwhile, transmit data over line-of-sight between radio devices. Web4 sep. 2024 · And just as radio waves from Earth bounce back down, waves above Earth’s ionosphere bounce back out.
