Dps 53744

[woodyrr]

Here I go getting a little (OK maybe a lot) nutty again. If any of you happen to stumble across TGID 53744 on the DPS system, I'd be very curious about what you think. I have only heard one extremely brief exchange Sunday morning, but that few seconds of audio sure got my attention.

Edit: I have decided to speculate - right or wrong.

Based on the flimsiest of evidence, I would not be surprised to find that MCPD has a few 800 radios to play with.

I would also not be surprised that it was actually somewhere in Gotebo either.

 

[PolarBear25]

Why do you say MCPD?? And it's not just a few radios it's a lot, And that is all I will and can say..

I'd be very curious about what you think

Woody--

I've been hearing them for about two weeks now. Mostly just checking radios and Emergency Buttons.

I knda figured they were part of the Norman switchover, but I don't have any definite evidence for that, except the timing. You know, there are a lot of different agencies on the Norman system.

Whoever it is also uses talkgroups 50672 and 52976. Several of the radios also do a check on SMA 1A (talkgroup 31760).

hmmmm,

--fast2okc

Also seeing new radios on talkgroups 49136, 54416, 48112 and 48880

fast2okc,

I have heard the emergency button tests, but the ones that I have heard have been associated with the City of Norman system, because, I can listen to both the city of Norman system and the DPS at the same time and have heard them switching between them with the tests. I have the idea that Norman might ultimately occupy the 43000 – 44000 block of TGIDs on the DPS system because their radio techs are on 43808 (Norman System) and last year at least, during OU games, Norman Police dispatch moved from 16016 to 43920 and Norman Fire dispatch moved from 19216 to 43952 (Norman System) and they used 44080 (Norman System) to dispatch “bike “ units to wherever they go and other units to incidents happening within the stadium. After the game the talkgroups reverted to their previous states. This year they appear to be doing it differently using I_tac’s, but I digress. On the other hand, the Norman PD patch is on 48624 (DPS) and 49136 (DPS) also carried some Norman traffic during the game last Saturday so where they end up is all a bunch of wild speculation as of right now.

As to 53744. What caught my attention was a number of things:

53744 is in an unallocated block by itself.
The user was unfamiliar with the operation of the radio.
The other party mentioned a street location which could have been in Midwest City, but could also have been in several other places as well, but not Norman.
There was The Oklahoman Online article posted by 2112 that mentioned that MWC had received its grant money and was shooting to be online by the “end of summer”.
None of that means much, so here is the hard part.

You all know, much to the annoyance of your friends and spouses, that you can have the scanner on and ignore 99% of what’s going on, but when something important happens, you can pick up on it in a heartbeat. I was ready to dismiss it as yet another mystery ID, but it was my subconscious that started pounding on the partition in my brain screaming for me to focus more intently on that talkgroup. I have been listening to Midwest City for 28 years. Maybe, my subconscious recognized the voice(s), or the way that the “location” sentence was structured, or maybe it put something else long buried together with what was being said and sounded a very persistent alarm in my head. So persistent, that I decided to risk ridicule by not only posting the ID, but also what I thought about it in hopes of having another ear confirm or refute my suspicion.

Not much to go on, I’ll admit, but I’ll tell you that after I heard that exchange, I was sitting on the edge of my chair with my eyed glued to the radio, and that very rarely happens.

 

[freqscout]

PB can't keep a secret so they probably wouldn't tell him anyhow.

 

[fireant]

Agreed......

Uh, oh. You have ... The Knack.

Pattern-matching is hard-coded in our genes, but not all of us can apply it to the radio. I bet you're spot on.

Still listening to the Norman system, but no new sigint.

The techs for both systems are all here - it'd be a lot easier if they just posted what they knew.

 

[Secret_Squirrel]

Agreed......

Bwaaaa hahahaha....

Once again, responding to a reported post; I wonder why it is some people want to blow their horns, yet add nothing of substance to a thread?

PB, you are well known for making short, useless posts in a thread; this one was a little longer, but still useless. Unless you plan on contributing, don't bother to post. This added nothing to the thread except opportunity to post more off topic comments (including this OT but necessary post of mine.) You have been warned in the past privately and also publicly, further warnings probably will not be issued.

I am not familiar with trunker or trunked radio much beyond frequencies and talkgroups. Are you saying that you are able to determine that 50672 and 52976 are somehow related to 53744? If that is so, and if TGIDs are spaced at intervals of 16 on this system, is it correct to conclude:

((53744-50672)=3072)/16=192 potential talkgroups between those two extremes. If they are related, I can't imagine Midwest City wanting 192 talkgroups let alone needing them.

Pattern-matching is hard-coded in our genes, but not all of us can apply it to the radio. I bet you're spot on.

Thanks for the vote of confidence, however, one of the voices that I consciously recognize on the Norman system is a voice from the Midwest City past, so it's entirely possible that I'm reacting to someone else who has made the big move. There has been somewhat of an exodus of recent from Midwest City to Norman, and I'm not necessarily talking public safety :wink:.

We'll just have to see what happens. I still can't shake the feeling of being hit right between the eyes with a brick, though.

Not necessarily, using Trunker, you are able to determine (after collecting a lot of data over time) what radios use (affiliate with) what TG's. It does not necessarily mean they are assigned to that, just that the TG is available in the radio. Most PS people (when first getting a new radio) end up going through the entire channel line up. On trunking systems that will reveal what is programmed in that particular radio.

You're on the right track. Uniden radios add the 4 status bits to the talkgroup code and convert the whole thing to decimal for radio programming purposes.

Nonetheless, you got the number right ... but ... if you look in the DB, you'll see that there isn't a whole lot of organization! The real talkgroups are hex so there are natural groupings ... but in reality, it makes little or no difference.

I "tapped" my 780 early this year and run Unitrunker. Lots of info on that data channel, including individual radios, and the software lets you tag both talkgroups and radios. Fun stuff.

Woody,

The problem is you are trying to use logic to figure out a government project. There is no reason to assume the talkroups will be in sequential order. Any new user group can be assigned any talkgroup number(that's not already in use). I am sure there was a plan when the project started, but it has simply outgrown that original plan.

Take a look at the Shawnee Talkgroups as an example:

30320 Shawnee REACT Ambulance
42544 Shawnee Police Dispatch
42608 Shawnee Emergency Management
55184 Shawnee Hospital ER
55920 Shawnee Animal Control
56176 Shawnee Com Center EMS and Fire Dispatch
56240 Shawnee Fire
56912 Shawnee REACT Private Channel
As you can see, the numbers jump around all over the place. The radios don't care, they just switch where they are told.

BTW, talkgroups on this system are assined in multiples of 32, not 16. It make the math more fun.

Do you remember the name of the street??

Ok again, I just wanted to know why he would say Midwest City Police Dept.

Well all EMS in analog start with 30xxx EMSA-8E (30256) Mediflight (30224) Shawnee REACT Ambulance (30320) and I believe you will see Midwest City EMS will be a 30xxx
troop A is 41xxx so any thoughts here people??

And lou magg I only have eyes for this system and seeing it be the main PS radio system in
the state of Oklahoma..

--fast2okc

Just FYI,
Oh this system yes, 32 is the magic number, however...
talkgroups that can be assigned on a motorola type II system (including smartzone) are actually in multiples of 16 - for some reason, many radio techs like to skip available talkgroups when numbering, so it seems like 32 is the magic number...
