FM has a better sound. FM has fewer reception problems. Millions of people have Fm radios, some housholds have several including car radios. Only people and companies with vested interests will want to scrap FM. These redundant radios will probably end up in landfill . It is so uneccessary and definately not for the public good.
I have both Fm and Dab radio. The dab radio has electronics built in to give the output a more 'Mellow' sound. In fact to sound more like annalogue Fm radio. I can make a direct comparison by switching between the two, however I still by far prefer the FM output. Are we to go digital just because all things digital must be better?
