On my way home yesterday, I came across the same officer trolling the same stretch of highway as the day before. The first time I passed him, he was parked on the shoulder with only his rear radar on. I know this because I quickly lost the signal about a half mile after passing him. I turned around at the next exit and headed toward. I was getting only intermittend weak alerts from him from a mile or so away. Just as I was in visual distance of him, I saw him light up the rear tires in an effort to chase after somebody. I was still only getting a mild alert. Right after he merged onto the road, the V1 pegged at full Ka and and the counter increased to "2" but then quickly disappeared back to "1".
Is it possible that he switched from his rear antenna to the front one? Would the transition between the 2 produce that quick second bogey on the V1?
This is the 2nd time this has happened to me while coming up on 1 LEO.
