Any solution to this problem with cars emitting k-band as safety features? Is TSR the only option and would it work for this? I'm noticing this more often now. Yesterday I was driving and my k-band kept going off about half strength. The road I was on has no falses, so I kept looking to see where the cop was (arrows would have be nice). Then I look in front of me and there was a mercedes e550. I figured that's what it was and about a half mile later after he turned and the alert ended. Very annoying; why can't these manufacturers use x-band or some other band not used by police?
