Been listening the the Fort Worth Oncor P25 site most of the day, trying to identify some talkgroups. First thing I noticed is the Unit IDs are basically the last four digits of the Radio ID for most users. They rarely give addresses or location data, mostly just something like "just north of where my truck is" so they must rely on AVL quite a bit. The one address I did get was in Keller. It associated with TG 143, they were talking freely, like on a talk channel. Seems like the Talkgroups must align with their service boundaries.

That and they also have different divisions like transmission and distribution and probably others.
On the EDACS system they had some type of systemwide talkgroups called Black Star. They used to do a weekly radio test I think it was on Mondays or Tuesdays between about 6-10 PM. Have you heard anything like that?
Most talkgroups are 3 digits except one, 65156 , haven't really listened hard enough to tell what kind of information is being passed, but it does stand out.

Talkgroups that start with 651xx are dynamically assigned patches. Sometimes the sites around here will have several talkgroups patched. 65535 is All Call.
I am friends with several Oncor Contractors and one is a radio nut (like the rest of us) He works with the Sulphur Springs office and is always bugging them for a radio. One manager finally broke down and gave the guy a lecture about how they rarely use the repeaters out here because they suck! Oncor crews in the rural area have 6 simplex frequencies they do the majority of their work on. I know in the Metro this isn't the case but in rural parts the 900 just don't have the arms to make them want to use it. I don't have the gumption to search those licenses to see what they are using for simplex. Should state for mobile use. If anyone feels the need to dig into that it would be good to know.

I did that years ago. I only found 4 but there could be others.

Tom, I'll plug those puppies in and start driving into rural Texas blackout zones and see what we can Identify.

Just remember they are itinerants so Oncor isn't the only user.
There is somebody around here that uses 939.975 PL 100.0 but I was never able to determine who it is.
