overall, the new V1 can be made to be quiet regarding K band falses in certain settings; that said, in the right place and at the right time can produce unsavory BSM alerts. It happens.

The purpose of this thread is to report/ explore BSM PTs (punch-throughs) running various V1 settings. This info can be useful for “custom frequencies,” mode settings, and for general discussion, and knowing what the “problem” vehicles are.

Please post your V1 settings, BSM frequency, offending vehicle make / model or other corroborating evidence, pics, videos, or app data.

#1
I was running in Logic Mode (small L) with K verifier ON and all K frequency scanning (no custom frequencies). So this was a little painful :ssj:- about a 5 minute 2.753-mile ride behind a Buick Enclave spewing K 24.067. Signal strength meter varied between 1 and 2 bars. Alert distance was point blank to about 100 feet. The gap of missing alerts in the middle of this BSM trail is when the Buick got some distance away from me. Screen shot is from V1 Driver. Conclusion- I may set up a K narrow range around that frequency.

Post script- wife was annoyed even with muting :aaaaa:

#2
This next one was a Town & Country minivan spewing 24.202. Same settings as above. Small L logic mode with K verifier ON. Luckily this was short-lived. Distance was within 50 feet. Signal strength meter was at 1 bar.

It seems like unlike many other detectors, BSM PTs on the V1G2 appear to be relatively weak signals. Sometimes a lot of bogey ghosting but it’s not like on an Escort where many BSM PTs are full strength K blasts out of nowhere.

Was the Buick also broadcasting 24.167? It should have been. That's the basis of one of the BSM filters.
Yup. I did get a 2 bogey counter just a few times - not the whole time. I went back to V1 Driver and had to click several pins but I found it.

I'm running A mode, X band off with K verifier on and my V1G2 is every bit as quiet as my R1's with 1.50 K filter, TFS, and K block on at 70%. It's also alerting sooner to 24.150 K band sources as well! so far it's a win win for me with no drawbacks or complaints! BTW, I've been trying out both JBV1 and V1 connection and I love them both!

Oh, Sorry. I was thinking of one of the BSM filters in JBV1. That will teach me to have a conversation with someone while trying to read a post on my phone...

The idea is that GM products tend to run two frequencies that are 100 MHz off from each other. (24.065 & 24.165, 24.085 & 24.185, etc.) One of the filters looks for that pair of frequencies (and some other stuff) and mutes. Perhaps V1 Driver has something similar or another workaround?

You may have already seen me describe this:
TMF2 in the Gen1 would resist alerting on a Honda BSM until I got to within 25 yards of the Honda. Because it was resisting a signal that was reaching farther than 25 yards, once it started alerting, I had to back off past 100 yards to get it to stop. One morning I repeated this observation 10-15 times and every time it was the same.

I suspect that K-Verifier in the Gen2 would have some of the same characteristics. It will probably resist a BSM to a certain distance, but once it's locked on, you have to get a decent range away for it to stop alerting.

How that helps here, I'm not entirely sure. :)

That is the most common K band frequency that I see from GM vehicles. Fortunately I get far fewer of them since I migrated to the R1.

@Kennyc56 that is good to know! I don't have a V1G2 (yet) but once they get the bugs out of it and refine the firmware I will most likely get one too. If I wasn't so happy with my R1 I would already have the V1G2!

You can graph the distribution of frequencies without having to keep clicking on pins. Keep double clicking on the “nnn records” text until you get a layout you like.

Auto Snooze will take care of those long BSM encounters.

You know how I feel about my R1's! You are going to love this V1G2 @GTO_04 ! Mine might blow up the next time I start my car but so far I'm blown away by everything the V1G2 is all about! That's only true however because I can use JBV1 or V1 Connect so I can still see the frequency, otherwise it wouldn't work for me.
That's a good thing however because they are both awesome! I don't know if you saw it in another thread I posted but the V1G2 beat my Ghetto arrows the other night against a State Trooper hiding behind a bridge also behind a good sized hill. Believe it or not, it beat my R1 by 7 seconds from the front and clipped my Redline-O by at least 100 feet from the rear, taking them both out on the same run! I went back and ran with the V1G2 off and got the same results with the R1 getting the signal at the same spot as well as the Redline dropping it at the same spot! The trooper must have been eating donuts or something because he stayed there for like 45 minutes shooting 34.7 C/O believe it or not! I got to run from both directions and the V1G2 came out on top everytime!

Anyone running custom K frequencies in higher modes like A? I guess it’s too risky in K areas

That should be no problem.
You could run:

24.050 - 24.060 (Skipping over 24.065+/- for your scenario)
24.070 - 24.250

34.400 - 34.900
35.500 - 35.700

and then still choose the muting level behaviors with A, l, or L. They are almost unrelated in this particular way of looking at it. For those that are new, the difference between A and l (lower L) is that some lower priority X & K alerts will be at the lower volume. All other factors should be the same.

BUT, it's been suggested and theorized that running Custom Frequencies might be what is causing some of the odd alerts that people are seeing.
I've been trying the factory configuration with X and Laser off, Bogey mute (Whatever it's called) and running in small L mode without app assistance. I finally turned on Lockouts yesterday just for fun. It's been a very well behaved detector in the last week.

I am using custom frequencies because of strange Ka alerts- some perceived Ka phantom signals

That is the same reason I'm trying no Custom Frequencies. We'll have to see what the consensus is after a handful of people try it both ways. :)

I am using custom frequencies because of strange Ka alerts- some perceived Ka phantom signals
Last night, while running an errand in a neighboring city, in Advanced Logic mode, I got what I perceived as two Ka false alarms (one at 34.715 and another a little later at 34.736). The ramp up never got super strong, but it was steady and then a little elevated.

On my way back, I actually had the same signals, and I spotted the two (three total) different LEOs (one was perpendicular about 40 yards off the street in a parking area likely doing paperwork , and the other was parked in a parking lot parallel talking to another LEO about 30 yards off the street about 1 mile later. The Ka sensitivity and off axis reactivity appears to be very good to excellent on the V1 Gen2. I am very pleased so far. I personally I am also pleased with my V1 Gen2’s K-band sensitivity to date. I do prefer running in All Bogeys mode, but I am still experimenting with Advanced Logic.

In terms of BSMs, I have had a few punch throughs from the prior model Buick Enclave (2015/2016 model style), but my V1 Gen2 has successfully filtered out some newer Honda CRVs with BSMs. I haven’t encountered a close up Pacifica yet which I normally see a lot of. So far the BSM filtering appears to be very good.

I have yet to have any Honda make a peep. That reminds me, I still need to make that video with my Wife's CR-V!

I don't recall having any Honda cause an issue yet, but I have had an Acura MDX punch through before. But doesn't seem to be all, or maybe you just have to be wthin a pretty close distance.

Funnily enough, I had an Acura pass me an hour ago and generated 9+ alerts. As you say, not every time, but it seems that K-Verifier will let it all out if it's not sure.

Yeah I have seen something similar to this in big-L mode. When big-L gives up, it will show you everything it’s been suppressing and not just the one signal that punched through.

This may be the explanation for the ghosting I was thinking I was having. You may be on to something.

in big L when I had my first Ka 35.5 alert, it immediately displayed Ka and K at the same time. I thought ghost and phantom K signal. There very well could have been a K BSM in the area. perhaps it wasnt ghosting K, it’s just that K was being suppressed but punched through when it alerted to Ka.
