I was coming up a hill when a car popped over it going the opp direction and my PRO 78 picks up X-band signal strength 2. When I get straight across from it I see it's not a LEO and the sig goes to 3. He turns right and I turn left behind him and sig drops to 1 and stays at 1 until I turn again 2 blocks later. This may be a stupid question but is there still RDs putting out false X???
