Well I was driving in the city right next to mine and got a Ka 35.5 hit and realized that they must have just recently upgraded (used to only use K). So I was driving around some more to see if I could get any more detections and I got a full Ka 35.5 alert (I assumed IO) but the patrol car quickly came into sight.
Then on my way home, a CPD cruiser was coming down the hill around a very strange corner and I got a full (IO-type) K band alert and the LEO rounded the corner shortly after. I haven't seen either city use IO, but I was wondering if these were likely IO shots or did it just not get any signal before to start alerting earlier. Both detections were severely off-axis and I was surprised that it even picked it up at all.
