I saw a statie on the median about a mile ahead and I did not get a cosntant Ka alert until I was about I was 500 feet from him. He had a CO Ka because while I was approaching and when when passed him, alerts were steady.
Here is the detailed scenario:
Four lane highway
I was on the #2 lane from slow side of the lane
Statie's radar gun was faced opposite traffic (He was shooting the cars on the opposite road)
I'm guessing since statie was shooting at the cars on opposite side of the road to oncoming traffic signals were not strong??
