This morning on my way back from my girlfriend's house, I saw a LEO (NY State Trooper) in the distance with lights on and a car in front of him. No alert. Just as I'm almost exactly right next to him, my 9500ix goes crazy indicating 34.7 Ka. When I stop, the alert goes away. But just as I move a little further away from the intersection, the Ka alert goes off a little more again, only to diminish shortly after. That seems like quite a short distance to initially pick up that alert. Is that normal?
