From an earlier thread about when to enable the "J" feature (even though it was actually Logic and advanced logic--Big L and little l) I decided I'd disable the false alarm guard for Ka. (also not to be confused with pop mode).
On my trip home from work, I got an encounter with one of the sneaky Utah Highway Patrol officers. In this encounter, it very much appeared that I increased my Ka band range substantially. I also got a local police encounter when I got to town with the same results!!!!
I've heard and know that when others have monkied with the false alarm guard, thier V1 goes nuts. So far (since I live in a rural area), no false alarms and my V1 has been as quiet as it has with it on yet better detection range. I'll give it a week or two and let you know more of my results then.
