    Pentru cei pasionati si cu un pic de expertiza in radio-electronica care nu au la indemana filtrele ceramice necesare ingustarii benzii IF din aparate dar care doresc obtinerea de selectivitate crescuta in cazuri extreme, reamintesc solutia sugerata cu multi ani buni in urma dar care a trecut nebagata in seama de catre ageamii, din motive lesne de inteles.

    Transmisie DRM in US, 15110 KHZ, radio Kuwait, 250 KW. Se vede pe spectru forma specifica a semnalului DRM, diferentiat fata de semnalele AM. Din pacate, DRM-ul este un tip de transmisie care nu a prins deocamdata, poate doar in India, experimentele dureaza de multa vreme dar fara prea mult succes. RRI are transmisii digitale in SW, dar limitate la 30 de minute in engleza, franceza, spaniola, chineza și cu o putere de 90 KW
