Remember, the list is a work in progress. There are a lot of Talk Groups that haven't been heard or Identified as of yet. It is gonna take time. For example, 3701 and 3702 are (I think) UTA PD (fare violators), and 2897 is U 0f U PD-Traffic Control.
I can confirm 3701 & 2 - radio aliases showing 54A and dispatch consoles are 944000x and show "UTA-DISP"

They are in the database already. Is there something you think is missing?

I programmed those Freqs.
What areas would be considered East and West?
I’m only hearing east dispatch I’m not sure if it’s skipping over west but even when I monitor west only I have no audio at all.

0 issue with picking up east , I’m in Weber county loud and clear on Nelson ( sds100 )

Not sure where you get "radio aliases" (I gotta look that up), but SDS displays are showing UID's of 8410xxx.
Apparently, Harris radios broadcast their actual radio name or alias with each call / command, and the tool I use (SDR Trunk) is able to decode that in the packet data sent in the control channel. This makes it easier to help decipher talkgroups and who they belong to, as well as determining radio ID ranges.

Screenshot for example - the "From" column shows what's actually sent with the data in the control channel stream. Sometimes the labels are NOT correct due to issues decoding, computer performance, or in the odd instance when a city installed a radio meant for one thing in another vehicle (American Fork Fire's radio in their Medic Ambulance 51 comes up as "CHIEF-51-M" as an example). So you do still have to still do the good ol' detective work of listening to confirm - this just helps the process.

And to your point about UTA...yes, RIDs in the 0841xxxx range are mobiles and portables for field units.

In this case, you can actually see on the third line down showing the RID of 08410179,54A-NIELSON-P (you can ignore the 92527.00A part...I forget what this specifically means, but it's something to do with the system in general). So you get the RID, and the label / name / alias / whatever the "official" vernacular is called of the radio. Sometimes they have the agency ID in there, sometimes it's just a string of numbers like Highway Patrol.

About only hearing east or west - it is entirely dependent upon if there is a radio affiliated with the talkgroup and said radio is also affiliated to the site you are monitoring.

For example, here in Utah County, we have two primary fire talkgroups: Fire 2 and Fire 3. Without going into too much irrelevant discussion, 2 covers everything north of Lindon and 3 covers everything south of Springville/Mapleton. Most of the time, anybody on the south end of the county is going to be affiliated with West Mountain. I monitor Lake Mountain (Utah Co Simul), so I miss the vast majority of their radio traffic unless a north end radio is sitting on Fire 3 and affiliated with the simul.

Does that make sense?

Okay, now I'm upset. I've been using Unitrunker V2 all this time, and it does not show "aliases". I gotta start all over again with SDR Trunk. :oops:

Yeah, I've mostly ditched Unitrunker at this point. Kinda frustrated with it myself.

I just wish SDR Trunk had Unitrunker's logging / journaling capabilities. It would be nice not to have to split my logs into 100 MB files just to view them in Excel...
