I just got a 9500i and it seems to be acting a bit funny. When I drive past a Ka speed sign near my house, most of the time it will start showing a second Ka signal on Exp mode. I've only drove past it a few times since I got the unit, but the few times I did, it did it almost every time. Later, I was messing with my Pro78 and the leakage. Sometimes when pointing the two at each other, it also alerted to 2 Ka signals, I know thats not a legit source but the Ka speed sign is. The sign was at 34.720.
