Discovered that on the IDPS S1, the former Beech Grove Fire Department Operations TG (10553) was suddenly being used for a while today. This was definitely not in conjunction with actual Fire Tactical usage by BGFD. It sounded more like it is now being used for Admin or Security traffic.. Overheard *105 to base. This is base, go ahead. 105 is requesting an shift change. Understood.* Possibly this is now in use also by Franciscan Health Security or does Beech Grove Schools have an police/security force like IPS? Makes me wonder if all the old BG TGs are repurposed now?
