    The apps have no control over J-Outs.
    His sweeps are hugely different.

    I do wonder though, maybe the "simple" sweeps are scanning quicker, quick enough to catch a weak short bogus Ka.

    Maybe so, I did go from a 6 sweep set to a 3 sweep set. Maybe this would decrease the time between the built in 33.8 set.

    I could have sworn someone has mentioned YaV1 had an extra setting or ability. Maybe on 2.04? I don't remember the setting, but I definitely noticed more J-outs after switching from YaV1 and I didn't change my sweeps. Maybe the V1 libraries we're updated at the same time? I don't know....

    Thinking about it, I'm fairly sure J outs increased when I reduced sweeps. Now I'm running a single Ka sweep.

    Unless you can reproduce the EXACT driving conditions with both settings and programs. It is a moot point. Without changing anything some trips i may get a bunch of j outs then go on for weeks without one!!

    It's a pop interference sweep section built into the sweep scheme which causes the J-out alert, and there's nothing you can do about it via the V1 itself unless you disable pop

    Not possible to disable Ka pop in Euro mode. Ka Guard is also a separate filter from the J-out alarm and this is automatically disabled in Euro mode.

    I believe there is also a general Ka false interference sweep independent of Ka POP, as indicated in the diagram (22.430 GHz Int. Bottom-23.800 GHz Int. Top). I remember seeing a J-out once to a 35.4xx (Whistler?) false, but didn't think much about it until now. I believe the Whistler LOs are around 11.8 GHz, producing a third harmonic Ka false around 35.4, but would also produce a second harmonic around 23.6 GHz which would be picked up by the wider Ka Interference sweep.

    I see this same J-out 2-3 times a week on my morning commute. Same pickup with what appears to be a Whistler (not sure of the model) based on its shape hanging in the window. This guy and I are obviously on the same schedule :)

    I've also noticed, or at least think I've noticed, more J-outs depending on which sweep set I run. Harmonics would appear to be at play here.

    I haven't received any j outs unless I have Ka guard on when I do a reset. I get 33.7 falses though that are about one Dot in strength

    Just thinking here;
    J-outs are a little annoying, but it is a newer feature of V1's that gives immediate notification of a signal and then says, "nevermind" (that's what I hear in my head :)) when it determines that it's a false signal.
    Why are we concerned with eliminating that? Maybe it's a good thing that they work again after converting to JBV1 from YaV1 in my case.

    It's where the V1 detected a signal that appears to be a Ka POP threat. To ensure you receive the alert ASAP it sends the alert through while continuing to complete signal analysis, since this takes a little time and these false alerts are at the same frequency as a legitimate threat. If it determines the signal is "junk" it retracts the alert and flashes a "J" with a specific tone letting you know it was a POP false.

    To me it's saying, "Look out!... Oops, false alarm." "If this had been an actual signal, I'd have saved you yet again!"

    Mine sounded better ... more personal. L0L.

    It was a joke like when we changed the Lazer Alerts on our LI s to play Bob Marleys "JAMMIN"

    Or " ". NICE TRY ". Or "". oh Sh!t "".

    My old LI setup SIRENS ALERT ---^ Jammin hammin jammin -- then "threat over".

    I agree, maybe things are working properly now since the switch.
