V1G2 - is it bad to create these custom frequencies to block constant Acura MDX BSM false alerts?

[bman3333]

So I sold my Uniden R7 because of constant K band falses from my 2019 Acura MDX BSM/safety system. The Acura system appears to operate K band from 24.158 - 24.170 and I could not shut the Uniden R& up unless I dropped rear K band sensitivity to 30%. I thought the new V1G2 would better filter, but unless I operate in Advanced Logic, the detector consistently alerts to my Acura's BSM in the 24.158 - 24.170 range.

So I read about setting custom frequencies within the V1 connection app and created two sweeps of K band, one from 23.908 - 24.157 and a second from 24.172 - 24.250. This has eliminated the alerts from my vehicle, but my fear is that I have also made myself vulnerable to K band hits. Is K band 24.158 - 24.170 commonly used by the LEO's in WI, IL or IN? These would be the states I travel in the most.

Thanks in advance for your replies.

Try updating to the 4.1023 firmware that was just released today first, I suspect it may resolve your issue.

K band guns can transmit anywhere within the K Band frequency. It's not like Ka band where guns are centered around a specific frequency. K band itself is so small that you are likely to see guns in any part of the frequency.

I have seen legit K Band as low as 24.091 and as high as 24.199. Plenty of times, I have encountered legit K Band in the 24.158 - 24.170 range that you described. If K band is regular, I would highly advise against making a hole like that. It's a total bummer that your car is polluting so badly that a legacy detector cannot handle the noise, but it seems like something that just has to be lived with for now unless you want to block out a significant portion of K Band (kind of like the K Block hack on Escort and Uniden detectors).

Yes, LEO's in WI and IL at least may have guns in this range.

If updating doesn't solve the problem, and it may not since I have the same issue albeit with a different car and frequency, there are some things you can try. Though I myself haven't come up with a perfect solution to me.

Mute rear K as pretty much all of the falsing comes from the rear horn.

Set mute to zero volume nad Run logic mode (little L). Most likely those alerts are 1 bar and will flash but be muted.

Get JBV1 and you have many more options like creating boxes like you did but only having them mute weak signals instead of nuking everything in between, etc. You can also have it switch in and out of Advanced Logic at certain speeds or even at the county line. You have a great chance of finding something livable with JBV1

 

[bman3333]

Thanks for the tips. I know for a fact that the city next door, Muskego, have LEO's with K band guns that normally show 124.120 +/- .003, but I was afraid of what you guys just explained.

Try the update and then try the least nuclear option first. I'd recommend starting by running in logic (little "L") mode and setting mute volume to zero. If that doesn't work well enough and you have an Android, get JBV1. If all else fails, kill K from the rear horn.

 

[Signal Environment]

Another thought would be to use JBV1 to keep you in Advanced Logic up to a certain speed, and then switch over to Logic (or A if you prefer). You can set the speed manually, or I believe you can tell it to switch at whatever the posted speed limit is (where the app "knows" the PSL).

I realize this is a somewhat different subject, but can someone recommend the best K BAND BOX(ES) for the most recent V1G1 using the JBV1 app? Naturally, I have the BSM filters engaged, but what is the best frequency or frequencies to enter in the field(s) for the K BAND BOX(ES)?

I don't run any boxes. Case in point. I had a leo at 24.151 while following a Honda Pilot and other cars that afterward showed at 24.124, 24.153, 24.161, 24.165, just to name a few. I never knew he was there until I saw him and the signal strength went above the Pilot!

K block is so uniden. What happens with the new firmware ?

the most recent V1G1

It almost got me too @Deadhead1971! He must be talking 3.8952.

@NVR2FST
When I look back at my boxes for the Gen1, I am a bit surprised that I used them. Some are less than ideal.
Here's what I had though: (Don't assume that it was a good idea!)
24.050 to 24.120
24.130 to 24.160
24.175 to 24.194
24.212 to 24.250
Everything out of those ranges were muted, but a caveat was that they were still loud enough for me to be aware of any alerts.
I of course used all the BSM filters as they became available as well.

Good news to report. After updating to 4.1023, I set a profile to default with Logic mode, saved it and pushed to the V1G2. The detector was quiet! No need to use the nuclear option as before. Props to V1 for fixing this issue with my Acura MDX's noisy BSM.

I'm really glad to hear it, no need for the nuclear option or hacking away with K block to get some peace and quiet!!!

Op delivers!

@bman3333 , I am glad firmware 4.1023 has helped. I have a similar problem with the BSM system on my Jeep Wrangler occasionally setting off the rear antenna on both my V1G2 and Max360c. I normally run All-Bogeys mode.

The BSM false alarms appear to be about the same (maybe a little less) on firmware 4.1023 on my Jeep. On a recent 350 mile road trip in the fall, (firmware 4.1021) about 80% of my BSM false alarms on my V1G2 were from my own vehicle.

We just drove about 400 miles down to the Atlanta, GA metro area in constant rain in our Wrangler with BSM, and it set off my V1G2 4 times which wasn’t too bad (mainly when passing Tractor Trailers) but my own vehicle still accounted 2/3 of my BSM false alarms on the trip.

I wish there was a way to run All-Bogeys mode on the front antenna and Advanced Logic on the rear antenna or some other method similar to the Uniden R7 rear balance feature to reduce the rear antenna BSM alarms from my own vehicle.

Keep in mind - K band legal bandwidth is from 24.025-24.225 (24.125 nominally) and 24.050 to 24.250 (24.150 nominally), which equates to 24.025 - 24.250. Guns near the end limits should/would be re calibrated the next time they were checked.

Just an FYI, about a year ago I had a legit 23.974 on I-20 outside of Birmingham, AL. Sheriff's vehicle near Leeds. My V1G1 was flashing like crazy but I didn't get an audio alert from JBV1 because I had a K-box set with a lower limit of 24.080. Be careful.

Yeah, that's why I said "legal", unfortunately there are unscrupulous departments out there not performing the required checks and violating FCC frequency assignments. I was mainly answering the OP as he was considering using custom frequencies to block reporting of signals in the middle of the band.

Your lucky it picked it up. Technically the V1 only goes down to 24.050. I know mine goes a little below the spec, but I will have to see if it works that low. Many years ago, I was pulled over with no indication of radar at all. Long story short, he had mistuned the gun so much it was outside of the detection band. When I called him on it, he let me go without even a warning. This is why I always run full bandwidth, no filters.

I thought the V1 went down to around 23.900, like the Redline-O and R7 on certain firmwares.

I just tested my 8 year old V1G1. It only goes down to 24.025. I think my V1G2 when I tested it wasn't significantly different from this. There may be versions that do go that low, but that is an extra 100MHz to scan over the base 200MHz(50% more), so it would hurt the scan rate on the older scanning superhets and not be by design. It might just be sloppy filters allowing it to happen on certain models.
