Just today, I have picked up two Ka 33.6XX signals (I've never seen a LEO using Ka in my area). The alerts both happened on pretty short notice and stayed at one bar. They also ended after I passed a small cluster (3-4 cars) of cars coming towards me. It also happened in a place where I only pick up an X band false.
Could these be from Cobras? Do Cobras leak in that frequency?
