Ok, so I was driving in the hospital parking lot last night and than tonight. Both nights I received X band, K band and to my surprise Ka Band? I did not know that hospital's run some Ka band. I was pretty sure every Ka I have ever got was a police officer's radar but maybe not every time after experiencing this. It is kind of a bummer because I almost thought 99% of Ka band was in fact real threats. Has anybody else got any false Ka alerts that they know where the source came from? If so, please post your false Ka experiences.
