If you need duplicate entries in your channel.conf, you can simply 
use a different 'radio id' for these entries:

from UPDATE-1.2.0:
  ... RID is an additional ID
  that can be used to tell apart channels that would otherwise be indistinguishable.
  This is typically the case with radio channels, which may have the same NID, TID
  and SID, but different "radio IDs". This new field is therefore called RID ("radio
  ID"). Currently NID and TID are not yet used by VDR and should always be 0. The
  RID is actually used when building the "unique channel ID", so if you have channels
  in your 'channels.conf' file that cause error messages when loading, you can set
  the RIDs of these channels to different values.
