Then they have shifted to digital, not analog. As already noted above, analog does not utilize NAC codes.\\
The radio service that installs the Sheriffs office (155.535) radios says there is a nac code 200 they installed on the mobile radios.
Burleson Co. Sheriffs Dept. Caldwell, Tx not Burleson Tx If your thinking about looking at radio reference it does not say anything about digital, I don't think. Thanks for the help.Steve, according to his first post... It's an SDS100...
Can not help much without more location info though...
I guess we have to be mind readers...
They may well be doing what I've seen in a number of other rural or semi-rural counties here in Texas. In quite a few cases, the Sheriff's office is using their dispatch channel both in analog mode (that's what is listed at present in the database), but also digital.Burleson Co. Sheriffs Dept.

While you could program it directly on the scanner, that becomes tedious as you try to get your text tag exactly how you want it. You have to select your letters, one at a time, by using the scroll knob to cycle through the alphabet.Ok, I believe I understand (sorta) what your telling me, but I'm new to the scanner community. From what you describe and by listening to communications, the SO pages the EMS on both fire and SO channels. When the EMS responds I always hear them and the SO. The only units I am not hearing are several, but not all of the SO units.
I think I understand what your telling me re: splitting the frequencies, but I just starting using
Sentinel and the SDS 100 and don't know how to plug in frequencies. Can this be programmed on the radio itself and if so what are the steps.
Again, thanks for being patient with me and hope Im not taking up to much of your time since Im a novice at this.
I've seen that pattern in a number of other counties in my extended area of North Texas, adding a digital format other than P25 to an existing license. Most add DMR, but I have seen several that instead added a NXDN option. There was one that I ran across a year or more ago, that updated their license to add both NXDN as well as MotoTRBO (DMR) emission codes, even though they continued using analog.If a guy was to look at the FCC licensing information ULS License - Public Safety Pool, Conventional License - KVX796 - BURLESON, COUNTY OF - Frequency 000155.53500000 he would see they are approved for 3 different emission types:
4K00F1D 6.25 kHz data NXDN (Narrow IDAS, NEXEDGE) 4K00F1E 6.25 kHz voice NXDN (Narrow IDAS, NEXEDGE)
8K10F1E P25 Phase I C4FM voice (typically used for single-site systems)
So there is a digital component in play for this frequency. Migration probably is in progress.
This is exactly the information I've been looking for. I will give it a try. Thanks for being patient with me and providing such detailed information. If I have any further questions, I will certainly get back with you.While you could program it directly on the scanner, that becomes tedious as you try to get your text tag exactly how you want it.

If you are using Sentinel, start the Favorites list editor, and select the list your county is in.
Go down to the system, for your county, and open the Department.

Now, just click over on the left margin, by where the number of the channel in the Department is.View attachment 92547
With the line for that frequency highlighted, as in my example above, copy that to the Windows clipboard, using the keystrokes of the Control key plus the letter C.
Once you have that copied to the clipboard, then add a line to the department by pressing the green plus sign.

Now, click in the channel name field (it's highlighted after you add the line).
Then, paste the line you copied to the clipboard using the shortcut keystrokes of the Control Key plus the letter V.

That copies everything from your original line. Finish it off by editing the audio option to reflect Digital, and enter the NAC key as well.
For counties that use the same frequency in both digital as well as analog mode, I add "Digital" to the text tag. That's my preference, but is certainly not a requirement.
Note that you can only add the channel this way if it is in a Favorites list. If you are using only the main database, along with your location and range, you cannot add the line for the alternate method of use.

Other than two NXDN public safety trunked systems in Dallas County, so far, the only other "non-business" users of NXDN I've noticed have been school districts
Update again. I think I got. Download new info on program as you instructed. I have now transferred to scanner and I will see if it starts receiving the channel.I hate to bother you again. I have tried the exact instructions you gave me. When I come to my favorites list and copy, I do not have a Audio Option in the horizontal column. What am I doing wrong?
You can change it via the Favorites editor, but not in the main, opening, screen for Sentinel. The only things you can do there are either appending a channel (frequency or TGID) to a list, like appending from the main database, or, if desired, you can append from one Favorites list to another list to add the exact same system details to another list. You can remove a channel from a Favorites list. You can also set, or remove, an Avoid on s specific system, department, or channel.I hate to bother you again.

"Negative Delay" forces the scanner to move on (resume scanning) if the conversation lasts over the set time. So, if you set the delay as a negative 10 seconds (-10), then after ten seconds the scanner will resume scanning regardless of whether the conversation it was monitoring is done or not. I use a negative delay on the automated dispatch channel for Dallas Fire Rescue. "Dispatch Debbie" has a habit of going ADHD, repeating the same traffic repeatedly (same address, call type, & units assigned).Steve, I have another question since I added the additional channel as you instructed. Too cut down on scan time, I changed the delay time from 2 sec to 0 sec. However, when the Sheriff's office is talking I am hearing partial transmission on one or the other channel. I notice on the delay chart you can go to -1 sec etc. Should I try this to eliminate the scan delay or what do you suggest?
If there's no activity in one site it goes to the next and waits there for the hold time and continous going to the next site if there's no activity. But if a site are active with calls and when the delay timer times out after the call is done it will skip all other sites in the system and go to next system. At least that was how it used to be. But it could have changed lately....You should only have the sites (or systems) of interest, that are in range, set to be scanned. You can use location to have those that are out of range disabled...
...Also remember that if you have the filter for one or more sites or departments set as "Auto", that will also drag down your scanning speed. When using auto, the scanner will try all the various filter settings to see which one is most effective. But it's not memorizing the the setting that was optimal...
