Here are several K-band encounters that I have had with my new CR97. The first one was about .8 of a mile on rolling terrain. I had just turned on this road from a side street, and the CR97 started alerting soon after. The second one was about .6 of a mile on rolling terrain with curves. I was pleased with both encounters as both would have allowed plenty of time to slow down to the PSL. On the second video, the Honda Pilot that passes me is a base model with no blind spot monitoring system. (My CR97 gives Ka band warnings to Honda/Acura BSMs and not K-band). Both officers were using constant on K-band. The CR97 changed from K-band to Ka-band once the officer was in sight on the second video. I passed him the other direction, and it was K-band all the way. I just think the CR97 was confused at the last minute on the second video. I am not sure if the videos will upload. I am still trying to figure out how to upload videos. I have much more experience with radar detectors than I do with dash cams, editing, and uploading videos...lol.
