I had two impressive Ka encounters today with my ix.
first encounter 34.7; I picked up a Leo from about a half mile, with a huge concrete overpass between us! He was about 1/4 mile from the base on one side (shooting into the base of the hill, not up the hill and into the air) and my ix picked him up about 1/4 mile before I got to the base on my side. Before I even started up the hill the ix was adamant that there was a LEO!
The second 33.8; was about 1/8 mile from a curve on the interstate, but the LEO was 1.4 miles up the road on the straight that followed the curve.
