I noticed some of the DSO channels were added to the database today, has DSO actually begun transitioning, or is this just a patch between the analog channel and the NTIRN system?

Any testing being done on talkgroups that may belong to DFR? Interested to see how they may change things up in terms of radios going from only a handful of analog frequencies to use to nearly a seemingly unlimited amount of talkgroups they could use for operations...

There's still a lot of patching going on. I heard some check-ins on 35083 today and it sounds like it'll be a Constables "Precinct 3" channel, but looking at the radio IDs most are not showing up, meaning they're patched and fairly noisy. Of course the ones that are on the system directly come in much clearer and radio IDs show up.

Thank you for the update Ben. Hoping to be able to pick up the Dallas NTIRN layers in NRH when I move back to TX next week, so I’ll run some Pro96Com sessions.

The talkgroups that I've logged so far suggest that TGIDs starting with 35xxx may be Dallas County users.
So far, 35050, 35051, 35081, & 35083 are listed.

Are there a lot of talkgroups active that aren't listed yet? or is it seeming ike just one agency at a time?

Hoping we'll start seeing DFR transition soon, really curious like I mentioned previously to see if they will be making use of multiple talkgroups instead of just the handful of frequencies they've been using for ages.

There are quite a few that are not in the database. Some have been submitted myself & others, but not yet updated in the database. I also have ton of audio files to work through, to see if I can discern a pattern as to who is using the TGID. Of the ones that I've recorded & listened to, nothing that sounds like Dallas PD or FD dispatch channels yet, but I have several thousand yet to review. There are certainly others trying to figure out the patterns.

Interesting that 35050 is definitely logging as ENC on Dallas Layer 1 but not on Layer 2... maybe due to the patch ?

30549 and 30550 are both active on Dallas Layer 1, with the actual Radio Ids populating. Both Encrypted.

Word is They (Dallas) are filling out the public works system first then moving to the public safety system. Both systems are separate of each other but will be a copy of each other in the event one goes down they have a duplicate of each other for redundancy. RRDB has these two listed as Layers which isn't correct per the powers to be, they are completely independent of each other and everything else (I don't know the technical stuff just the info).

Word is the radio folks are waiting on the DPD chief to decide whether to encrypt or not encrypt everything. Its probably safe to say deployment, Narcotics and Investigations and all special ops will be the big E. But, Dallas City of is all about public transparency and building trust in the community so its hopeful DPD Patrol dispatch might be in the clear.

Also, (AKA) Layer 1 is 22 channels all under the State of Texas license - None of those frequencies are licensed to the city of Dallas. Apparently Collin (PAWMCO) also does this for a few.

Ya'll might want to get a Broadcastify Calls node up on these Dallas layers. You'll be able to go back and listen to every talkgroup captured - really helps to identify stuff.

DPD chief wants to encrypt everything and get rid of the online call log too. He tried to get rid of the call log early this year and that didnt go over very well with city council and the community. Thankfully it's not entirely up to him. And many DPD special units are already using push to talk LTE for surveillance. Not sure they would come back to using a new TRS for this purpose but who knows.

If I recall 30549 and 30550 replaced the DPD Fugitive 1 and Fugitive 2 talkgroups that were on the Dallas P25/NCTCOG system. I haven't been able to completely confirm so I've been hesitant on submitting it

That makes sense. I haven't seen those talkgroups active on NCTCOG/Dallas recently.

I didn't think to until now but I went back and compared radio IDs across both systems and talkgroups and it does show a few of them are the same, not many though. I'll submit it to the database, I feel pretty confident.

While "layers" is not necessarily the politically correct name for sites, NTIRN (as well as it's original name, FWRRS) has always called the first two Fort Worth sites as Layer 1 & Layer 2. It simplifies noting which site a department, and it's talkgroups can be found on.

Also, (AKA) Layer 1 is 22 channels all under the State of Texas license - None of those frequencies are licensed to the city of Dallas. Apparently Collin (PAWMCO) also does this for a few.
While the frequencies currently used on Dallas Layer 1 are from the state license (which also means that we cannot see the actual subsites being used for the simulcast coverage), the unknown factor is what happens to the "Dallas Simulcast" site on the Dallas P25/NCTCOG system. I've seen comments previously that supposedly, the NCTCOG system would go away by the end of this year. If so, those frequencies could, instead, be repurposed for the Dallas Layer 1 in lieu of the state licensed frequencies. Obviously, their license would need to be updated to reflect all of the various Simulcast subsites. For that matter, if NCTCOG goes completely away, the frequencies on the NCTCOG Dallas site would also become available. These are also licensed to the city.

I noticed that, originally, the frequencies used on the LCRA site in Brown County (Brownwood) were from the state license. However, now Brown
County as well as Brownwood have acquired heir own licenses.

I get it on the "Layers" and for us scanner folks its a non-issue. but for those who take it so serious that if they don't dot and i their OCD kicks in, I offered it up.

Good question on the other frequencies, I guess its all speculation until we see them redistributed in the scan list. But as for
"Layer 1" its fully 700 and fully built and functioning. Those others could be added later for gap filler sites or expansion, guess we'll just have to wait and see.

There apparently is a shortage of 7/800 spectrum in North Texas (Imagine that) The State wasn't using the frequencies and if they are not used eventually go back to the FCC for someone else to use. Makes sense for them to be used on Dallas.

A note on the encryption thing, For example, Dallas Fugitive Squad, They have always had encryption capabilities for those groups. Instead of a unit saying to go to "Channel 6" they are designed to say go to "key 6" utilizing the group better. Also, DPD Fugitive/Parole squad is different than the USMS/DPD Fugitive squad which also complicates matters as that is fulltime encrypted. To better be able to communicate all radios in said group would have encryption key shortcuts so no one is bouncing from TG to TG or needing patches galore.

So flooding City council members email in-boxes wouldn't be a bad thing?
