O knihe
High Quality Content by WIKIPEDIA articles! Skywave is the propagation of electromagnetic waves bent (refracted) back to the Earth's surface by the ionosphere. As a result of skywave propagation, a broadcast signal from a distant AM broadcasting station at night, or from a shortwave radio station (or during sporadic E season, a low band TV station) can sometimes be heard as clearly as local stations. (This is distinct from 'groundwave' propagation, which is direct from transmitter to radio). Most long-distance HF radio communication (between 3 and 30 MHz) is a result of skywave propagation. Since the early 1920s amateur radio operators, limited to lower transmitter power than commercial radio, have taken advantage of skywave for long distance or DX communication.
