First of all, I think SWS is gay. I haven't encountered a single SWS. Anyone regularly encounter these signals?
Instead, they have these K, Ka band beacon trailers that transmit signals at construction sites and other places. Now they installed these things on expressways on overpasses to deter speeders.
I guess it is better to transmit Ka band and make all the detector go off, rather than saying "CONSTRUCTION AHEAD" since then people with detectors will slow down.
I remember the stupid QVC shopping host selling detecor saying, "Get this one for your son or daughter. It may save their life as it will tell you when there is a hazard up ahead."
Whatever. :roll: But then I guess all these stupid moms who were clueless bought it anyways.
