Driving home late last night on a four lane road with lots of businesses on both sides. Got a one bar Ka alert for a few seconds then went away as i was going up a small hill. Top of the hill picked up one bar Ka again. Stayed at one bar for what seemed like forever. Ka started ramping up quicker to a full Ka alert. On the other side of the road coming toward me was a LEO running c/o Ka. I always get great range on c/o Ka but this was unreal so today i drove the route again to see how far the detection range was. I measured it at 3.1 miles. And that was to the spot where he passed me not to where it actually picked him up cause he was driving in the other direction. Just wanted to share it.
