The coloured area on the map represents the locations where DAB reception should be possible in a car, or using a DAB receiver where the aerial is above ground-floor level. Those areas showing shaded with bright colour (one colour per DAB frequency) indoor domestic reception even at ground level should be highly reliable: please remember that the receiver aerial position and how fast you are moving can affect reception reliability.
kuergun: Planet Rock changed frequency earlier this year and is now available from fewer transmitters than before. If you haven't already done so, perform a full scan on your radio to update the station list and you may find that a new entry for Planet Rock appears. If you provide a postcode we'll be able to see which transmitters cover your area and offer further advice.
