Here's the scenario:
I spotted a LEO today while traveling in the north direction. The LEO on the other side of the road was facing north as well and he was trying to nail those drivers heading south. My 9500i picked up the Ka band but with the usual ramp up problem (2 bars on display with no ramp up). Can the Ka band hit me since I was moving away from the LEO (the rear license plate view)? There wasn't a whole lot of traffic at that time.
