In order not to have to send information across the entire network, the destination country or the destination region can be determined by specifying transmitter groups.
The transmitter groups are assigned geographically according to the following scheme:
|all||All transmitters on the network|
|dl-all||Transmitters in dl (Germany)|
|dl-nw||Transmitters in North Rhine Westphalia (state in Germany)|
|dl-nw-detmold||Transmitters in Detmold (district of North Rhine Westphalia)|
|on-all||Transmitters in on (Belgium)|
|on-lg||Transmitters in Liège (district of Belgium)|
In Germany, group names are based on the following map:
In Austria, group names are based on the callsign prefix of the 9 states (Bundesländer): OE1 to OE9, e.g. oe-oe1
Transmitter groups for clubs and organizations are not assigned for the following reasons:
Widerange transmitters should always be member of all geographically fitting transmitter groups. Please do NOT join transmitter groups that are located somewhere else! Doing this can mess up the rubric system of all Skypers in Your coverage area! Being member of special groups like „dxcluster“ is optional, if You are running a personal short range transmitter, You are free to choose any transmitter group You like.
