Getting back to the R15 - Another feature on the R15 is "Category" which didn't make much sense to me or why I wanted to use it when I first read the instruction manuals. (I know, why read the manual, only read the manual when all else fails).
However, once you start manually or software programming the receiver, it becomes very obvious that it is a useful feature.
If you have say 7 groups that contain frequencies about airplanes, airports, or ARTCC; it becomes very handy to have all of them in a CATEGORY called "Planes". Then when you get ready to scan for airplanes, you don't have to scroll thru 20 or 30 groups looking for airplane groups. The groups numbers might be 2,5,6,10,12,15, and 23 but those groups are lumped together in the Category called "Planes".
If you have say 5 groups that contain frequencies about railroads or trains, put them in a CATEGORY called "Trains" and then you can easily find them without scrolling thru 20 or 30 groups.
Same thing for Police, Fire, and EMS if there are any analog ones left in your area.
If you are like me, over time you started "adding" new groups of frequencies and after a few "adds", the directory is in no particular order and you have to look thru the entire directory hunting where you put something. In other words, we don't carefully plan our scanner or receiver organizing.
