This morning I was driving down the highway in A-mode and I got a few K alerts. I slowed down even though it was just two blips (I never get alerts in this stretch, no doors or buildings nearby for falses), and not far ahead there was a PA state trooper. He wasn't broadcasting as I passed him, so does that mean he had used IO on some other car and I was able to detect it?
I had a similar situation with KA-band once, a few hits and never even saw a cop.
Still new to the game, and learning what I'm detecting..
