Recently, on this system, in Ohio, I've heard new talk groups being used that include 24008, 24009, 24018, 24019, and 25000. The 24xxx talk groups seem to be used in a factory setting, and I'm not sure about the use of 25000. The 24xxx groups are concentrated on the Toledo sites including Irwin Road and Hill Avenue and sometimes on the Oregon site. 25000 uses the Irwin Road and Hill Avenue sites. Has anyone else heard or identified the users of these talk groups? They are not included in the database yet.
