Possible checking making sure each TG is working correctly? Where I live at in Bay Cnty PCFD can work on different tacs bay fd works on E tac N tac depending what zone they are in PCBFD uses 2 different TG . Maybe Flagler Cnty is doing this?There are Flagler ISSI TGs in the 201xx range showing up on the St Johns TRS but they have no set pattern. In particular Fire Primary will stay with a TG for one day then change to another TG the next day. Any reasoning for this?
