I had this K band encounter with my V1 Gen 2 at night. My settings are mostly factory default. I am running Advanced Logic (L) with the K-band verifier on. I am headed EB, and the officer is parked on the right shoulder facing EB too. Judging from the ramp up, I am almost positive this officer has their forward facing radar on, and I had 1 on the bogey counter. Once I get the first warning, it is about 19 seconds when I pass the officer parked on the right shoulder. I mostly run my V1 Gen 2 on All Bogeys (A), but I am experimenting some with Logic and Advanced Logic. The PSL is 40mph.

That was damn good, and he was shooting out of his front antenna just like you said! So much for K band being weak on the V1G2!

That rear detection after you pass seemed a bit weak (depending on how obstructed your rear horn is). Being that low if you were approaching it would not seem a threat at that level yet he would already have your speed.

Advanced Logic hides signals that transition from front to rear rather quickly after they go to the rear. I would chalk that up to the logic analyzer and hope that it’s smart enough to be more worried about an increasing or initially encountered signal from the rear.

This was in Advanced Logic (L), so I was definitely fine with that warning. I know some of the testing has shown the V1 Gen2 isn’t as strong as the R series on K-band, but my “hunch” in my limited K-band encounters with my V1 Gen 2, when I am running my V1 Gen2 in All Bogeys mode, it is comparable to my R3 in K-band on Highway mode. I have only had mine for 8 days, but I feel comfortable with the V1 Gen2.

My V1 Gen2 was mounted high under the right sun visor with the windshield mount with the front antenna just under the shaded top of my windshield. I am not sure what direction the front antenna was pointed, but I agree that ramp up on the rear antenna and urgency of the warning wasn’t very strong.

From my experience with speed signs, Advanced Logic seems pretty impressive at letting those through at around 2-3 bars reliably but it will suppress door openers often until they're close to full strength.

I think we need more testing on Advanced Logic. It seemed to affect K band relatively more in @Vortex's test against regular power K, but in the earlier TX tests against low-power K there a smaller difference between Advanced Logic and All Bogeys.

In any case, these tests have all reflected that you still get adequate advance warning until the kill zone on advanced logic. So we are extrapolating our worry to extreme off axis or IO encounters....

Perhaps we should really structure a test like that! Who can design a course where Advanced Logic would get you owned but all-bogeys saves you?

I'm always going to run the least amount of filtering I can! I went straight to A mode, turned X band off and left K verifier on and so far it's alerting before my R1 on 1.50 with K-block, K filter, TFS on at 70% like I always run them. I have several 24.150 sources for K band I'm basing this on till I get my radar guns back from @VariableWave ! I've driven to work for 2 days now with the V1G2 and all over the place and I'm all good with A mode and K verifier on.

At 40 mph it is barely over 1000ft. If it is low power K then not real bad but if normal K then maybe not so great. I realize it is Big L and FF, so it is hard to rate it without other detectors to run in the exact same situation for a reference.

A big factor we don’t know right now is whether or not the range reduction for high power K translates to low power K or IO. I think we have more testing to do there especially since the V1G2’s manual specifically mentions that they let through I/O.

For the given situation, it was plenty of advance notice. If they were more cautious on K band then I think a lot of us would be asking for “even bigger L” or some other super filtered mode.

That was an argument I unsuccessfully had with Stinger for the whole time I was helping them test. It would pick up off axis speed signs maybe 30% further than a Redline with TSR OFF, in the most filtered mode. They disagreed for a long time and eventually added a “+2” quiet level beyond the +1 level they used to have.

@jdong - I think you are mistaken. TXCTG tesing showed ~50% reduction between A mode and Big L against Low-powered K on the front horn. 20%-30% rear horn with shorter detection distances. @Vortex's testing showed about a 25% reduction front horn only against regular powered K.

Agree that more testing is needed.

I wonder how much of that is gun-dependent and how much is terrain-dependent.

Me, too. Need more testing, as always. ;)

haha I guess that’s always part of testing, isn’t it? We learn a lot, but then it raises more questions about performance with different detectors, settings, terrains, guns, etc. :p

You're right, I got the two mixed up. Oops! Thank you for pointing this out.

Not much to reflect back towards front antenna either. Full Logic works well, IMO.

Rear horn is cut back more on full logic.

Well, GEN2 was not 50% less in your test than R7 in city mode, with all bands filters on, and on Segmentation/narrow on R7. GEN2 holds is own, or better than R7 set to be false alert quiet on the street.

Or how much is Street quiet settings dependent? I don’t like testing with Ka filter off, K narrow, K block off, TSF off, and other settings that without these make R7 non-livable (maybe on I90 N SD the exception). Plus, no one has the magic latest antenna settings for combination of quiet and alerts tested with R7. More testing is also needed for rear performance.
