    Sorry this took longer than expected

    Nick and I did some R series GPS testing last weekend and it was rough - we spent almost 3 hours trying to get separation before we even got to the actual runs... we stew tested, then we measured the course and tried to do runs, then more stew testing, then adding the eccosorb... until finally we did our regular course, same runs as last time - only difference, we added the eccosorb for the actual runs. These detections were less than 1000 feet

    Here's the chart:

    GPS Testing Draft 2.


    Settings were the same that Nick, Me, and most guys in NY/NJ run regularly:
    Advanced Mode
    KA 100%
    K 40%
    X OFF
    K Narrow
    K Filter ON
    KA Filter OFF

    3 Runs a Setting - Tested against Stalker MDR 34.700 @ThreePedals6.2

    The only changes to the settings were City Mode to Advanced Mode and GPS ON, RLC ON, SPEEDCAM ON v. GPS OFF, RLC OFF, SPEEDCAM OFF - all three were ON or OFF as indicated by "GPS ON" or "GPS OFF" in the chart

    @Brainstorm69 R3 and my R3 gave opposite results, which was strange and frustrating. But, me and Nick came to the conclusion that whatever we did there was only going to be feet of separation when turning GPS ON v. GPS OFF. It would take 100s of runs to get a true average, whereas our 3 runs a setting was subject to regular detection deviation. So, "it is what it is" and more testing it definitely needed.


    I know @Jag42 had some theories and threads about the R3 and how the GPS affects the detector - unfortunately more testing is needed because our results are inconclusive

    We are open to suggestions to try to get some good results - we have more tests planned for the future but this was a tough one

    What radar gun/band were these tested against?

    It would make sense that the GPS causes a slight processor delay during a scan cycle or slightly reduces the scan rate, and may have an impact on reactivity. If that is the case, differences will be most apparent when traveling at higher speeds and/or testing against weak long distance signals. In these cases any delay in the alert will translate into much larger differences in detection range, since you will be covering more ground (higher speed) or may not see the signal consistently (fringe detection range).

    Thanks for the testing, I know it's a ton of work! I think we can at least say for those of us in the Northeast where detections are usually terrain limited, turning GPS off won't make much of a difference.

    X2, when you guys post your results (and many thanks by the way), make sure you put the type of gun that is shooting (Stalker DSR 34.7 for example)....

    --- Post updated ---

    Thanks, this is what we are looking for. The type of gun makes a HUGE difference.

    Thanks for testing

    It looks like the signal is blocked by terrain

    In the future if not getting separation

    Determine how many feet out the radar gun can get a lock
    How many seconds you had for the save etc so testing is not lost

    Thanks for the efforts, gents, as you already well know, frustrations can/do/will abound when testing detectors and sounds like this one might go down as the most frustrating of yours yet!

    But positives can still spin off when results are inconclusive like this; such as your credibility. We know you're not making the results up! :p

    Thanks Pat. Thanks as well guys. Tough one this time, but I think this is the most "real world" example as of yet.

    Such a slight difference in this example. Just the way it is sometimes.

    Thanks for your testing efforts, guys! It is frustrating when things don't work out the way you'd like them to when testing, but it goes with the territory. @Jag42 and I have tested many a time where for various reasons, things didn't turn out as we expected, or we didn't get separation, or results were inconclusive and/or conflicting.

    As an example, in our R3 segmentation testing results (www.rdforum.org: TXCTG - Uniden R Series FW 1.31 Segmentation Ka 34.7 and Ka 35.5 Testing 10-08-2017), we had some results where Ka Narrow on a detector somehow beat segged 2/5/8, or where 2/5/8 somehow beat seg 5 only on the same detector.

    The results are what they are, and all you can do is report them as they happened. As mentioned, it just means more testing and/or testing on a different course may be needed to see if it is repeatable, or if it was just something about this specific test or course. Again, that's why we always say it's just one test, you need to look at various tests, by various folks, on various courses, and under various conditions to get a full picture of a detector's capabilities. ;)

    Thanks again, and keep those tests results coming! :)

    Great job guys.
    So you only learn through experience. Looks like not much separation happened here. I would have thrown in a Redline or V1 just to show "R" series separation either way.
    It takes a lot of time to do these tests whether you show separation or not. I dont have the time so "we" appreciate you taking the time to experiment guys.
    Thx for posting and keep on testing!

    Thanks for the kind words 3 pedals. We sure will!

    A bit tied up ATM, but we plan to soon.
