I'v got my V1 set up as listed in my sig. The cops here in NZ only use Ka and LASER enforcing gear, the last of the K gear being ditched about 5+ years ago. The good news is that this means that I can turn the K and X bands off, greatly reducing my need to filter false bogyes out. I can drive around the middle of a city and the V1 is as silent as a sleeping baby, regardless of the mode (A,l,L).
On the open highway though, I'm getting about 5-6 false Ka alerts for every actual LEO. So far, the V1 has never given me a "J" signal. I end up getting a alert from the V1 and find myself scanning the horizon looking for a cruiser... more often than not it's some anonymous car going the other way with a couple of suction cups on his windscreen. I gather that using either of the logic modes won't help here as they don't affect Ka band?
The V1 has worked very well thus far and the falses around town are non-existant... it's just pi$$ing me off a little that the level of falsing on the open highway with junk signals from the plethora of low-brow detectors on the market might cause me to start looking at the V1 like it's crying wolf.
