Do you understand the difference between a Group and a System your Uniden programming?     In this episode, Phil explains use cases for groups and how to set them up, and how to create quick keys for them.   What You Need To Know Groups are important to optimize your scanners for trunking. Systems are the container for your trunking and conventional systems in your DMA Scanner. Groups are where you store your frequencies or Trunk Group and Unit IDs. You can have up to 20 groups within the system. Each type of group and system can have their own quick keys defined. Using groups allows you to organize different precincts and battalions by location, for example, grouping all Manhattan NYPD frequencies separate from citywide NYPD frequencies. While you can add up to 20 groups per system, you can only map out 10 group quick keys.
