radio propagation model
Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere.
As a form of electromagnetic radiation, like light waves, radio waves are affected ...

. SPLAT! can use the
Longley-Rice path loss and coverage prediction using the
Irregular Terrain Model to predict the behaviour and reliability of radio links, and to predict
path loss
Path loss, or path attenuation, is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system. ...

History
Development started in 1997 by John A. Magliacane, KD2BD. The latest version 1.4.2 was published in 2014. In 2020 several authors started the development of a completely reworked version which was not published yet.
The authors introduce multithreading, georeferenced outputs (
