On the way to work I picked up a K band signal while I was turning onto a street. It was a constant K band signal with a strength that kept going between 1-3. I kept looking for the car and couldn't see it. it was a 30mph street so I wasn't going to fast and couldn't figure out where this K band signal was coming from. Finally, as I approached an intersection that is approx. 1 mile from where I started picking up K band, I see the officer approaching the intersection, we both crossed at the same time, and he wasn't stopped, so I got over 1 mile K band reception, I was pretty impressed.
