Has anyone encountered a Ka radar with no front off axis alarm but when in the direct beam off to the side there is a side alarm of 4 leds and then a rear alarm of 5 seconds fadeing when passing? The 3.872 did this 3 times as a Leo had a car stopped at a side stop sign. His radar was on pointing across the 4 lane. Is the front horn on the V1 so directional that is looks only straight ahead? There should have been some radar signal bouncing off of the pulled over car for the V1 to see but the fairly new V1 had no front alarm in the 3 trials? Makes me think something might be wrong with the V1. Any ideals?
