I was using a 'search' on the Bell County (TX) EDACS and logging it, and noticed these funny looking TGIDs that came up. Ex: "i08210" Anyone know what they could be? (see photo)
If you enter a TGID on your Edacs system like for ex: 04----, or 07----, and sit on that TGID it will bring up all "users" on that TG that use ID' s starting in 04--- or 07---....Cool feature.....
The software screenshot in the OP indicates that he is using what appears to be UASD software and thus, excludes the possibility that he is using the XT series radios.
As already stated, what you're seeing as "strange" are, in fact, I-Call IDs.
