Are PSP troopers testing a new device? Last year my detector would pick them up, no problem. It was always the same band as the speed reading signs on the side of highways (K/Ka). Recently, every single PSP unit I have passed (while obviously doing radar) has not set off my detector, even one little blip. I even witnessed one unit pull out into traffic for a stop, after watching radar, so I know it was being used. Just curious if they are running something new in terms of Radar, or testing laser or something else?
