So I was driving up in Moraga, CA around Saint Mary's College and I got a constant K band reading.. At first I was like it could be a speed sign but knowing the area I was driving, there was none there. So I was slowed down and then I see a cop hiding on the side of the road. It was pretty dark so I didn't know if he had his radar gun out or not but does anyone have experience with cops using K band radar detectors in California, especially in Moraga? I thought K band radars aren't used in California used anymore. Could it have been just radio signals coming from the cop car? The signal was pretty constant because it acted just like a radar.
