I understand that the 9500i is not designed to lockout Ka by three touches of the mute button. Would there not be any practical way to get a Ka lockout by means of a special software external command? Several times a week for the last 6 months I've have to travel within sight of an (apparently permanent) advisory sign that emits an extremely strong Ka signal that I start getting annoyed by when I'm still five minutes away. I know most Ka is speed radar but plainly not all is actually so dangerous. Why the heck didn't Escort provide for Ka lockout!!?
