MW (taajuusalue)
MW-taajuusalue[1] (engl. Medium wave, MW, suom. keskipitkäaaltoalue, keskipitkät aallot tai keskipitkät) on Euroopassa 526,5 kHz– 1606,5 kHz[1] radiotaajuusalue, jota käytetään yleisradiotoiminnassa amplitudimoduloiduissa (AM) lähetyksissä.[2] Aaltoalue on porrastettu 9 kHz:n välein. Yhdysvalloissa keskiaaltoalue on porrastettu 10 kHz:n välein, mikä tarkoittaa, etteivät aaltoalueet osu kohdakkain kuin tasakymmenluvuilla, minkä vuoksi radiovastaanottimessa tulee olla valinta kummallekin jaolle, mikäli vastaanotinta halutaan kuunnella kummankin taajuusjaon olosuhteissa.
