radio de onda curta

radio de onda curta

A radio player that is able to receive high frequency (HF) signals of the radio spectrum, between 3,000–30,000 kHz. Shortwave radio obtained its name because its radio wavelengths are shorter than those used for medium and low frequency bands originally used for radio communications. Shortwave radio is ideal for long-range communication as short waves travel much longer distance in the Earth's atmosphere.
