    Looks like you guys are right. I mistook it for distance measurement. Mea Culpa!

    Yikes. I wish I could get away with that, eliminate all the Honda/Acura BSMs, for example. But I've personally run into a legit K-band source near New Braunfels, TX, running at 24.195 or so. I would have to have missed that...


    That's showing 35.5. You're saying the Falcon HR produces the same kind of signal on K-band? Because of all the detectors tested, only the DFR9 had any trouble picking it up...

    TO BE CLEAR, during testing we absolutely did not turn off K filters on the Unidens (or anyone else)! :)

    Yes, it does.

    You guys (not specifically you, but other forum guys) sometimes test with cheaper guns like the BallCoach too. Sometimes you will notice detectors filter it out when filtering is on high; it's the same reason why.

    I was thinking in the detectors comparison sense.

    Exploring how a specific detector's different options and filters affects its performance is defitely a valid excercise though.

    I realize this is a little late, but I don't think we are talking about "a few more" falses. My old man bought a R3 4 months back, and he has a lot more k band falses than my Pro M, and that is even on the TSR Low setting. I was able to borrow his for a few days, and it has been my experience that the Pro M has a K band filtering edge like the R1/3 has the radar sensitivity edge.

    Don't get me wrong, my father is satisfied with the R3, and I did originally recommend he buy one... But since getting my hands on the Pro M, it's sweet driving around not partially ignoring k band alerts. I'm trying to put this in terms, and I guess a way to describe it is I get just a few more k band false alerts than I get ka band false alerts. I mean, it's not perfect, but it's damn good IMHO. lol

    Lastly, Thanks to the testers for taking the time to post these results. My only request would be to make more runs, and to turn TSR off, so that we can see what kind of a hit in range we might be getting.

    Thanks,

    You still have K narrow and K wide available.

    Then it’s a mute point because the Honda/Acura’s don’t seem to affect the Radenso’s like my R3 or Escort products.

    If you get a chance Deacon, you should try and get your hands on one for a week.

    I had the same question, so I tried it out to see.

    In City mode. No filter. FW US 8 at the time.
    Against my Bushnell. Probably would’ve been further back against a real Leo K gun, but the difference in the effects of TSRej would be the same.

    Effects of TSRej off, low, high.

    The Pocket Radar? Yeah it's handy for quick testing, but it's not a police radar gun. However, there is a version of it that's certified for traffic enforcement so it'd be good to ensure that you can detect it even with the filters enabled.

    Well you guys are experiencing one of the issues with testing a tough K Band gun ......in this thread.

    Different CM manufacturers utilize different methodologies to defeat BSM.
    Generic comments must be carefully considered as they do not necessarily apply to every manufacturer.

    So we only have the time to slow and feet from gun as the end result of our (testing) efforts. We dont have BSM filtering test results. Just sensitivity and performance as feet from gun measurement.

    From that (test) data each owner of various manufacturers units can look at the configuration of the test units and compare their own personal BSM filtering results in their own environment and compare to the sensitivity/performance results in the test. The testers don't have that data. You do.

    I have same problem with my Original Scan Gauge that sits on my dash when I'm driving in the summer for an extended time. I cut out some thin white cardboard and basically build a little house to cover the top sides and rear area from the hot sun. The over heating problems which would disable the display are no longer a problem.

    Look at getting a piece of white paper and cutting in a way to cover the top and sides of the detector to cut down the amount of light hitting it. Think of it as a sun shield for your detector.

    That seems to be the consensus. I don’t have a Pro M to run to know personally, but I wonder if you were to cut the R3’s sensitivity down to the Pro M’s level if you would have the same experience. If I had to guess, I’d say you’d probably still get some more BSM alerts with the Unidens, but that's hard to say.

    The notion of disabling all K filters entirely would require a dedicated day and, in my personal opinion, wouldn’t be particularly useful, mostly academic, as I can’t imagine many who would really run it that way on a daily basis. Sure, some might, but they would be very much the exception. Also, please see the full write-up on this thread regarding the number of runs and all that. www.rdforum.org: LowPowerKBand Shootout

    In city mode do you recall what k band sensitivity was set to?

    Does the Pro M actually reduce sensitivity, like the R-series do, when in City vs Highway? Or does it just increase the alert threshold?

    I don't know 100%.... but will go with some logic.. I believe the RPSE has the ability to reduced sensitivity for K band in city mode, hence why I think the Pro M does as well.

    City vs Highway switches it from your user defined sensitivity reduction (0 to 90% reduction) to Maximum sensitivity. (0 reduction)

    IIRC, the K filter I think is still active if you have it turned on though...

    Yes.
    I did a step test way back in December 2017. It was -21C.
    I think it was on FW 4 back then.

    Same Bushnell. I started at around 5500 feet and recorded each distance lost as I stepped up the filtering.
    By time I was at K9, I think the distance was 1000 feet.

    Synistyr is right.
    The TSRej remains active regardless of the mode it’s in. It’s like an extra K band filter. It’s just named weird. Micheal from Radenso mentioned as much last October.

    I think we went a little too far off topic here.

    Crappy components by design/on purpose, allowing the changes/drift in attempt to thawrt RD’s? Or, by accident they send you and possible others back to BSM elimination drawing board? Software able to account and fix this in general or with specific KS radar profiles (like a door opener) which would bypass the BSM filter and get a better alert?

    Appreciated your detail on this. Not too many of run spectrum analyzer in the field. Should comments like yours above also become topics inside Redenso area? I would enjoy learning more. If you think you need to put posts in areas with special access (like advanced members have access), keeping roving public LEO eyes off that content, maybe Admins would allow you to invite less elevated to that conversation too. Just an idea.

    Piggy backing on discussion to this very interesting comment. Did you see in those results, what speed @Vortex ran each test? I cannot speak for Radenso, but I believe on ER, anything below 45-50mph, the “auto” setting reduces K band sensitivity. On purpose. To help with K band door openers originally, now possible helps combined with BSM filter. Notice the difference in range when ERs R in some form of “auto”. He had “Lowk” also on which reduces the auto setting more. How does a Redenso filter? As you indicated, maybe we could learn more on this. Does the Redesnso, like ER dynamically adjust K band sensitivity based on speed when in its version of “city” like setting (max filtering)? Maybe that could be one reason for poor results on the barn test. During the curves leading up to the barn, the speed might have been under the threshold that raises sensistivity for K in a rural/highway setting. In addition to @Jon at Radenso suggestion that the K band gun for this TX test gives his BSM algorithms fits, plus the barn test results you posted above, puts a counter message to a positive Radenso ability to filter out BSM and have good range.

    We really need to get a hold of the new Stalker patrol low power K band. I'm hoping to get one by end of September.
