talk group Naming and allocation
This is done by the Servers in each country.
If more than one server is in your country, you work together.
In the UK we have some rules for ones to follow.
World Wide Talk Group
This is a list of all Named Talk Groups in use.
Users can also use non named Talk Groups via OPB.
