Register for DMR
Before you start using DMR you will need to register for a DMR ID. Once you have completed the registration process, which includes uploading a copy of your amateur license, you will be issued (currently by email) a unique seven digit DMR ID. For UK stations it will start 234 or 235.

This ID should then be entered in to your code plug.
You will need a valid ID BEFORE you can use the network (Brandmeister or DV Scotland Phoenix).
This is a separate process to registering for D-Star.
