When I was in Indianapolis back in October, I heard IMPD talking simplex car to car on their VHF frequencies. At the time I heard it there were several cars that were coordinating stops on people that were leaving a known drug house. Considering it was analog and in the clear I was surprised at how openly they were talking about things. It was as if they thought no one could hear what they were saying. Unfortunately, I don’t remember which frequency they were on but it was definitely one of the VHF tac channels.
Since it’s in the same area, I thought I would mention that on Friday night I was watching on patrol live and I noticed that Beech Grove is definitely using their low band to talk simplex car to car.
