MW tuner

The Tuner MW parameter of a HiFi receiver indicates its ability to receive radio broadcasts on medium waves. The abbreviation MW comes from the English "Medium Wave", in Czech the designation SV is commonly used for this band. It is a waveband that uses amplitude modulation technology, known as AM, to transmit sound. This differs from the more common FM transmission, which is used on very short waves and offers higher sound quality. The sound quality on medium waves is generally below that of FM broadcasting. The sound is often monophonic, with a smaller frequency range and may be more prone to interference and noise. The main advantage of medium wave, however, is its ability to propagate over long distances, especially at night, allowing reception of stations from distant countries. Today, this band is mainly used for spoken word, news or specific music genres, rather than high fidelity broadcasting.
