Prune stations
If you move to a different part of the country, some of the stations
which were listed may no longer be available. Also, from time to
time, some DAB services may stop broadcasting, or may change
location or frequency.
Stations which cannot be found, or which have not been received for
a very long time are shown in the station list with a question mark.
The Prune stations function will delete the marked DAB stations
from your station list.
