I only assume that since we are not locally using the new system (yet) they are sending some different talkgroups up to test the system. I have also heard several units from southern Louisiana that were in the Shreveport area calling their dispatchers and telling them they are in the Shreveport area.
This morning I also heard Troop C Dispatch....and I hear a couple of the DOT groups in the Baton Rouge area almost everyday.
