Okay cool. So can you like have only ka on L and have Ka + K on l [lowercase L]
Logic mode "lowercase L" reports all X-bands, but reports them only at the muted volume. Advanced Logic mode "uppercase L" doesn't report them unless they're serious and then they come on. In my experience, even Advanced Logic mode did very little to all the X-band signals in my area. So I keep my in L mode (doesn't really matter now though) and I have X-band manually turned off and Ka sensitivity increased in the programming. I wouldn't turn K off unless you're absolutely sure it's not used where you live.
