Every portable K-band radar traffic sign I have ever seen, is placed on wide open flats in areas like school zones, dense neighborhoods, and changes in PSL locations. On the way home last nite, 4 miles from the center of this town, on a windy very rural road I get a K-band alert on the RX65, and thought, "here comes a local with constant on K-band around the curve", so I got into the binders hard and put her nose on the ground.
Lo'n behold there's this blasted K-band sign out in the middle of nowhere. Range to target was not good because it is firing into the woods with very little to scatter the signal. I suspect some residents complained about people flying around the curves, and they are getting some close calls when they enter from the road to the lower left. I fully expect the sign to be replaced or joined by a cruiser within a few days, and this town uses K-band so only the higher end detectors are going to let you know what's happening before it's too late.
I went back and tested each detector a couple times, one powered at a time of course. Range on the RX65 was about 600ft, and on the V1 about 750ft.
