rövidhullámú
Rövidhullámú, meaning shortwave in Hungarian, refers to radio waves with wavelengths ranging from 10 to 100 meters, corresponding to frequencies between 3 and 30 megahertz (MHz). These frequencies fall within the shortwave radio spectrum. Shortwave radio is known for its ability to propagate over long distances, often spanning continents, due to its interaction with the Earth's ionosphere.
The ionosphere, a region of the upper atmosphere containing ionized particles, reflects shortwave radio signals. This
While advancements in satellite communication and the internet have reduced its dominance in some areas, shortwave
