Yeah, we see that here too on the GM's (I mainly see those 2 on Cadillac's). Honda/Acura seem to be more common on the roads though. This year we also got introduced to new Mazda BSM systems in the 24.129-136-ish range that bounce around. They're strong enough to set-off my V1's rear antenna when passing one on the road in the opposite direction. Fortunately they're less common, but seem to be increasing.You guy's are lucky - we get the GM's in that range and also at 100 MHz lower, as each door mirror uses a separate frequency for BSM (i.e 24.078 and 24.178 GHz) on the Holden Commodore (Chevy SS)
Revised K5 segment would solve 90% of my BSM issues.We only have 6 segments currently to work with and its really only a temporary solution since we have bigger plans next year to combat these issues further but as a temporary solution would changing the existing 6 segments help many of you?
Existing 6 segments:
K4 24.100 - 24.150
K5 24.150 – 24.200
K6 24.200 – 24.250
Existing NR & DSP just like Uniden do not scan below 24.050 so the current 1 & 2 Segments are not even used so we plan to change the segments to the following:
K1 24.000 - 24.100
K2 24.100 - 24.165
K3 24.165 – 24.180
K4 24.180 – 24.195
K5 24.195 – 24.205
K6 24.205 – 24.250
What are your thoughts?
I have had BSM falses as low as 24.196 and as high as 24.204, so BRD’s proposal for K5 actually seems perfect, based on the falses I’ve had. Would love to get more actual data behind theses ranges, though!If you can't do single digit like a .197 and have to do "by 5's" like .195 then so be it... what you propose would help a lot!
I totally agree. Yes, they all (BSM) drive me crazy but where I live, I think everyone is buying Hondas and Acuras. LEOs are still using K-band here, but 19 out of 20 K-bans alerts I come across are BSM and the vast majority, Hondas and Acuras. I now find myself not paying any initial attention to K-band. That can ruin your day especially if LEO is using I/O.
That's a lot of work on your part. Thanks for sharing.
Actually, I have been noticing some GMs lately that also cause falses around the 24.06x-24.07x range. Good info to know.You guy's are lucky - we get the GM's in that range and also at 100 MHz lower, as each door mirror uses a separate frequency for BSM (i.e 24.078 and 24.178 GHz) on the Holden Commodore (Chevy SS)
The work was done by @Flonase. Thank him. I just added what I have seen as the culprits to his data.That's a lot of work on your part. Thanks for sharing.
Regarding notch filters, one possible way to minimize missing a LEO while reducing BSM noise would be to include an optional setting for the notched frequency range of alerting only visually, or only visually at minimum volume. This way users wouldn't have to choose between all or nothing for the blocked frequencies.Our plan was to have the Net Radar DSP automatically learn to ignore certain frequencies of LCC equipped that the Net Radar DSP has installed on but its not feasible to do this at this time on the existing ALP hardware and still existing auto learn patents.
What I was thinking is that we can add some selectable notch filters to make life much better for some customers that are willing to risk locking out a very small section instead of a large segment.
If we could add lets say 5 small notches what would you all prefer?
Blocking part of a frequency using band segments will not give an alert if that segment is turned off.I personally dislike the idea of a “half alert”. I’d rather have a filter be a true filter. If we get a partial alert even with the filter on, just make it a full-on alert. To me a notch filter that still gives a partial alert defeats the whole purpose.
