There are occasions when people learn from the familiarity with the region, terrain, etc.
The SDS 100 carries a rather severe learning curve.
For right now, you might want to turn the national DB on. Then, go into the radio menu & toggle the "service types" you don't want to hear (examples: utilities, other, ham, media, etc.)
Then, go into the scanner menu, go to "Set Your Location." When it is parked on this, push the rotary knob down & it will land on "Set Your Location." Then, go to "Set Range." You can set the range according to the area.
As you scanner scans, you can rely on the national DB label (alpha tag) to show you what is possible for to hear.
Some of the talk groups (name for channel in a trunked system) & conventional frequencies will already have labels on the radio for you to ID them.
I see where it is possible to monitor some federal, some state police, etc. However, some of these talk groups/conventional frequencies have a "E" beside them. If you see a capital "E" it means that full encryption is being used. If so, no scanner can monitor a full "E."
If you need some help, send me and PM and I can program the radio for you. Then, you can model what I've created to fine tune it the way you like.
I am completely unfamiliar with the terrain where you live.
There are two potential places to program from: a)
New Haven County, Connecticut (CT) Scanner Frequencies and Radio Frequency Reference and b) a trunked system that encompasses state police, etc.,
Connecticut Land Mobile Radio Network (CLMRN) Trunking System, Statewide, Connecticut
I don't believe the best way to learn how to use this radio is throwing more wood on the fire. If so, you are likely to get smoked out. When I first learned, it was overwhelming. I had friends helping me. We started with the basics.
I am giving the following as an example of why it is helpful to break things down for those having difficulty reading, absorbing, and implementing novel material.
For example, I used to to write behavioral programming goals for ID clients to tie their shoes. Some low-functioning individual need 300 steps on learning small tasks. In essence, I found myself as clueless as one of my clients for learning complex tasks.
Invariably, those with intimate knowledge of something tend to talk over the heads of those learning how to do something without gearing the information to a novice. Maybe they believe in "cognitive osmosis."
Take it slow and steady.
