While driving around with the SE i have noticed while in Ka max mode and filter mode is opening doors to Ka9 falses by certain large microwave towers. I was just in Clovis NM. and there is 3 large microwave towers near my uncles house and i recieve 1-2 second Ka9 falses all around the area. I drove right up to one of the towers and got a 34.0 Ka9 false. Simply by turning off Ka max i never recieved another false. As soon as i would turn KA MAX back on the Ka9 falses would come back. Just thought i would share. I would turn Ka max off in a very heavy populated city and turn it back on for HIGHWAY driving if you have issues with Ka9 falses. Ka max and filter is quiet for me. I'm driving another 1,000 miles with the SE next weekend.
