When you start your HamSphere transceiver you will have the look, feel and sound of a real Amateur Radio transceiver. The ionization due to the radiations from the sun based on Sunspot Numbers (SSN) and the Solar Flux Index (SFI) determine the behavior of the Ionosphere and follow the 11 year solar cycle. It also models hundreds of kilometers of atmosphere above the earth's surface, the ionization of gases in the upper atmosphere to realistically produce ionospheric layers. The HamSphere propagation model takes in to account the physics of planet Earth, its surface topography like the continents, land masses, water bodies, oceans, eHam's Product Reviews are intended to provide an opportunity to share an opinion, positive or negative, of a commercially available ham radio-related product or service. We are talking about the propagation conditions. Products to be reviewed typically should be tangible ham radio related items such as radios, antennas, towers, test equipment, feedlines, etc. how well we can reach distant places by radio worldwide. Because it is also the main cause for what can be achieved on shortwave and other bands, i.e. HamSphere is a unique platform, the only one of its kind in the world providing the experience of a realistic HF radio.įor radio amateurs, the sun has a very special meaning.
