I was driving home today in the 100 degree heat when I came across a known K band false spot (along a shopping center). Usually, I get a weak alert, around 1-3 in strength, then it just dies as I drive further away. Today, it started out at 1 strength, went to 2, then jumped up to 8 immediately. It stayed there for a second or two, then gradually went back down across all of the numbers, 7, 6, 5, 4, 3, 2, then to one and went back to "City 2".
It could have been a LEO sitting there where he knows there is a K false, and uses I/O radar on the same band to try to fool users. Although I didn't see a cop around, and usually in the city they use KA, but I guess anything is possible.
What do you guys think? If the detector got too hot would it cause weird readings like this? I don't leave it in the window when I park (I carry it with me, strange as that sounds), so I don't think it was overheated.
