I'm assuming this had to be from a cobra or something, but couldnt find any car with a visable detector near me. I was on my morning commute today, and as I merged from one highway to another, I got a few Ka blips from the rear. Looking at those merging from the rear I saw no sign of an LEO. Then it stopped.
A minute or two later at a light I got a strong steady Ka alert while I sat at a light to the point where I was certain there was an LEO behind me. After the light it deminished for a while and then I got a few short blips and they were in front of me. Then nothing. I tried to see which cars may have passed me since the merge but saw no signs of detectors. I assume thats all it could've been right? No J-out on them though.
No signs of an LEO at all within these couple alerts.
This was all in locations completely free of any falses up till now.
