the other day I was driving into school, and my bel 955 went from no alert to 5 bars X band instantly as I passed an oncoming car, the alert went away in about two seconds after I cleared the car. My friend has complained that he has been getting k band alerts on his V1 on the school campus. their aren't any automatic doors on campus, and it's at least a half mile from the nearest shopping center, so the only thing that i can think of that would be causing the false alerts are cobras. But in my experience cobras only make my 955 false ka band, and sometimes pop. Has anyone else ever experienced this?
