I would be very interested in seeing a "map" of a beta testers unit in how they use the LBS for the areas they monitor.
Ok, below is a snippet. The large circles are the default settings for Fort Worth and Arlington systems. However, for my day-to-day use, I've split the area into multiple systems with multiple "sites" in order to limit my reception to the immediate area that I am in. I've shown what I did with Arlington, below (did similarly for Ftw, but not shown). I have 3 Arlington systems: North, West, and East. Each corresponds to the patrol maps for PD and has only the TGID's for that patrol's PD operations. All systems carry FD/EMS (which are dispatched citywide off of the same channel).
The use of multi-site allowed me to create irregularly-shaped coverage areas for each system to more closely approximate the system's coverage to the patrol area being traversed.
