Bell County P25

[Ensnared]

I am still attempting to identify some Bell County P25 talk groups. Hence, I am still attempting to find out "who" is talking. One of these talk groups is not listed in the RR DB; however, it is partially encrypted. I believe this is one of the talk groups I converted from Temple PV.

Since I have not identified this yet, I am not going to submit it. Therefore, I need to know one thing.

Does the unit ID pertain to the radio, console, or officer/dispatch?

If it is by dispatch, does this change with shifts?

I'm not sure if you are referring to the unique Radio ID (RID) that's programmed into every radio on a trunked system or the unit ID that is voiced over the radio(that is assigned to officers or other radio users). Assuming you referring to the RID, those would be programmed by the radio shop, but there are definitely patterns you might notice if you look at enough of them for a particular system. I've seen some systems where console RIDs are within a certain range of RIDs, mobiles, in another range, and handhelds, in another range. Then there might be ranges for cities, departments, etc.

Not sure if that's what you're getting at. If not, you might need to clarify what it is you're needing help with.
Happy Scanning!

I am talking about the Unit ID that is an option on the SDS 100 screen or 436HP. That is all I know. I am confused. When it shows up, it correspond with the person talking, by simple voice recognition. I usually notice this in Waco on HOTRRS, late at night, on the "sensitive" talk groups. Generally speaking, they are watching someone or on observation. When they talk, they both have different numbers.

I don't think it is their LE number, unit 4032 (example). I don't know if it is unique to the radio or officer. I am trying very hard to make this simple for my simple mind. Once I learn, I may be able to differentiate talk groups.

For instance, I am seeing dispatch showing the same ID. However, I tend to forget to make notes of the ID with a different dispatcher.

Unit IDs in the Uniden scanners are the same as Radio IDs that I described above.

It will depend on the department using the radios. For some firefighters, police officers, etc will have each have a radio assigned to them. In other departments the radios might be assigned to a position, like Lt., Captain, Firefighter, Sgt. etc.(that changes with shifts).

Every radio should have a unique RID. Generally, the ones in vehicles will stay the same for as long as that vehicle is in service(regardless of shift). Same for dispatchers. However, vehicles and people move within departments and roles, so even those RIDs can change or appear to not follow a pattern after a while.

Hope that helps.

It helped a lot. Thank you. Since I know this now, the next question is how Bell County uses these RID. I am going to star using the detailed screen to pay more attention to this and log the information when I can.

Thank you!

For now, I believe that Dallas PD assigns portable radios to individual officers, though vehicles have one unit in them. I have not bothered to nail down DPD UIDs , because as you've already noted, the individual office, or patrol car, might be used in different areas on different days.

For DFR, I've good a fairly good list of UIDs for fire & rescue equipment, as well as a portable for that unit (when they specifically say something like 'Engine xx will be clear on portable'). DFR dispatch appear to be using one set of UIDs, 7000801 to 7000811.

This is one thing I miss from the old SWRCC NXDN system. in addition to the basic UID, you could also pick up the alias for it, such as CHPDxxx, or an individual fire engine or truck company, plus command level users.

I know that LE in Waco use radios that they pick up. However, the special assignment officers seem to have a different set of radios, for them. I will start paying more attention. Thanks.
