Unidentified TG's on OKC/DPS system.

40400- Moore PD Unit affiliated to it.
51728- Moore FD Unit Affiliated to it and it is in line as the next TG after FD Dispatch. Could be Fire Tac 1 or whatever they call it.

Others:
43088
44080
45200
58448
58480- These last two are also in line..32 apart seems to be a standard deviation for numerical TG assignments. There were no histories on the units that affiliated to these TG's.

I think I know how you are distinguishing channel lineup -- tell me if I'm right. The radios affiliate to different talkgroups every time they change channels and you see what order they do it in. Is this correct and is this how we figured out quite a bit of the EDACS system?

Yes and yes. Each time they select a different talkgroup they affiliate and the computer recalls what the last TG was that they were affiliated to and uses that as an identifier rather than a permanent name which is given when you finally ID the unit such as ID 48349 is Village Brush Pumper 4 where it was [xxxxx]NicholsHills/Village Fire. The x's in brackets would be the number for the TG ID. I track a lot of this activity through the TG's and that is how I determine which units are affiliating to the TG's as well as the one's with permanent ID's. If one radio bounces back and forth between Moore PD 1 and 2 for a long period of time (days/weeks) then there is a good chance that this radio belongs to a Moore PD officer. It isn't a foolproof method but it does get you into a pretty small ballpark area of the TG if it doesn't get you there outright.
Yes, this method was used to ID a lot of EDACS TG's.

I would assume you also are able to watch activity on the screen as you listen with a scanner? Like you see which unit IDs pop up when a particular person keys up the radio and identifies his unit?

 

[freqscout]

Yes, that is how I get the permanent ID's, especially for OHP units since they do not change handhelds and cars as much.
