I noticed after the first day of messing with aliases putting PD unit numbers on radio IDs would not be the way to go as they were changing after a shift change, I will probably just put a generic tag of some sort .
In my somewhat local big city, the PD does not have radios installed in the cars. All officers use portables only. So, I would expect radio IDs to be forever changing. Maybe you have the same situation
Currently, I am logging radio IDs for my local suburban FDs (my only real monitoring interest. Former member.) I really like having the truck ID (Engine 2, Ladder 10, Chief 3, Dispatch, etc) coming up on the screen vs. the radio ID number. I really like this new capability. Thanks Unication.
