Was on my way home from a trip across the state in Pittsburgh. While I was driving on 926 through Chester County, I noticed a hit of K Band (first picked it up before the intersection of 52 and 926, if you're from the area). I immediately slowed down to PSL, and saw some cones on the road (apparently there was some sort of fair going on outside).
As I proceeded up the hill, I noticed a marked township police vehicle. As I approached, the K band signal got progressively stronger, giving a full strength alert as I passed the LEO. The signal became weaker as I moved away from the car.
I don't believe that the LEO was undertaking traffic enforcement, due to the nature of the situation (the cones on the roadway, and him sitting to slow down traffic). I have heard stories of PSP officers sitting in with locals to write tickets, but there was only one officer in the car, and I'm 95% sure this officer was one of the normal officers employed by the township. I didn't see any obvious signs of a radar gun...the officer did not have a handheld apparent through the window (could have been below the dash, as my car cannot see into the windows of an SUV). Did not see any signs of a 2 piece K gun as well, such as those seen mounted on PA K LEO's, and there were no PSP on the road for the duration of the trip.
The township does not own a K band speed sign, AFAIK at least (and, unless it was in the neighborhood, the hit wouldn't have maxed there anyway, as there was only a right turn into this neighborhood available.) It was definitely a huge K hit, in an area where there is no falses (houses on one side, field on the other, and I drive on this section at least once a week without false)...and the signal was full strength.
Whatcha make of this PA guys?
