Three common use cases:
1. Only Standard messages. Easy to implement. Call sign, rough locator (worst case about 50km off), power, all neatly packed into one message.
2. Alternating between standard messages and messages with extended locators. Usually used to give a more precise position e.g. for moving mobile stations.
3. Alternating between message with prefixed call signs and messages with extended locators.
If you have to use prefix, this is the only way to transmit your full call sign and a locator.
The prefix will also be part of the hash so your messages can be matched.
