I was driving around on Fort Riley, a US Army post today, and my RX65 started beeping for KU band. Shortly after I saw a Military Police car in the other lane. I don't know if he was using his radar at the time and mine was just falsing or if the military actually use some KU. All the other times I've been hit it has always been KA. Does anyone know anything about this or was mine just giving me a fasle alert?
