The only problem I have is on a very old, Gen 1 DAB radio which occasionally loses its connection for a few seconds and then picks up again. My other, newer, radios are perfectly fine. On those, I flip between R4, 4Extra, 5 Live and 6 Music. All of them are pretty much glitch free. Marple should be able to recive DAB from Sutton Common, Sunley Building and good old Winter Hill. Mind you, I have clear line of sight from the top floor of my house to Winter Hill and the Sunley Building. Reception does depend on what geographical features are in the way of the signal as well as the type of construction used in the building you're trying to listen from.
