Testing V-1 on K-band, need input.

[RacerX]

Thanks.
This has turned out to be a lot more involved than planned.

Well i just repeated some of the tests with E and F on the highway. Actually an open country road.
The good part is, that i got about twice the range here (5+ miles).
Of course this meant twice as much driving.

Now in reference to the above post, it seems that when E and F are both changed, it causes all loss of short range warning. With just F changed, it actually isn't quite as bad, but you still lose warning about 80% of the time. Definately not acceptable.
Another quirk i've noticed which is prolonging my testing is a constant inconsistency with the V1 on k band alerts in "L" mode. In the city with E and F changed, you can forget about early warning. On the highway it's a 50/50 crap shoot as to whether or not it will alert from several miles away. On close range i again got past the gun from a mile away before it would alert, and of course i was already clocked.

Now the biggest problem i'm having is with inconsistent runs. From 2 miles out it will sometimes alert every other 1/2 mile on instant on. I can even park 1.5 miles away and depending on the amount of times between 2 second bursts, sometimes it will alert and sometimes it won't. This is in "L" mode just to clarify. In "A" mode, it alerts fine with plenty of warning every time. I even got 3 miles of rear warning with instant on.

At this point i'm going to run the final tests and report it. then everyone can draw their own conclusions and decide what modes best for them.
I'm also adding 3 more highway tests. One with "E" changed and one with just "F" changed and one with both changed.

Also it seems that changing just "F" will cause the V1 to alert to ka instead of k at close range. This is with the tester and radar gun. If it does it on the highway test i'll let you know.

FINALLY!
I figured it out. I now know what causes the inconsistencies. I can now repeat them each time and work around them for consistent results. anyway i'm in my truck now still testing while I have a bit of sun left. gotta love this TREO.
the results are rather interesting.
back to testing. now i'm a happy camper.

Okay, i'm getting close to wrapping this thing up. Yeah, i know, about time. That's what i'm saying too.
Now that i've figured out the timing scheme on this i can now report consistent results, and explain why it seemed to alert to occasional weak alerts with E or F enabled.

Once i'm done i'll post a copy of the whole test procedure for download to anyone who wants it to use or change for their own testing. It'll be an 8-14 page word doc.
To conserve space, i'm going to summarize the test results as compact as possible so you can read them here.

One thing i will say, is that even with the quirks i've posted elsewhere, i'm liking the performance of this thing. Right in the middle of my testing yesterday, i was doing some rear testing, and during that i suddenly started getting a signal to the front (k band). I was in "L" mode at the time with "F" changed, so it wouldn't alert until the 6 light barrier. In this instance i was at a 5 sec delay. it was alerting at just 1-2 lights. (i'll explain how/why it broke the barrier in a bit). 1.5 miles later i passed a Deputy moving with constant on. We were both doing about 50, so this means i picked him up about 3 miles away.
The reason i bring this up, is that it is possible to make the V1 almost dead silent on k band. However the quieter you make it, the less range and warning you have in certain situations.
As you'll soon see in the test results, Instant on is the most affected.
If you only deal with constant on and no rear threats, then you can make this puppy very quiet and still get some good front warning.

Having said that, i still stand behind the warning of changing "E" and "F" together. Even though there are only 8 lights on the V1, i think it's adding the 4 and 6 together for 10. Meaning, until it breaks the time barrier you have set with b,c,d it will NOT alert, even at full blast close range. The ONLY way it will alert is if it waits until the time you set with b,c,d, Regardless of signal strength.
"E" or "F" alone, will work as expected, depending on the delay you have set.

Now the reason i was getting inconsistencies has to do with some type of "timeout" on alerts. For example, say you have "E" and "F" at deafult, so it will alert immediately if the signal breaks 4 lights. Regardless of what time delay you have set, if it alerts, then after it has stopped alerting, it takes 10-14 seconds for the time delay to "reset". What this means is that if within that time frame it picks up even a weak 1 light signal, it will alert immediately, even if you had "F" changed to not alert until after 6 lights and set a 30 sec delay. This is why it will break any barriers you have set, this is why even weak falses seem to defy the barriers and alert anyway. Now once this time passes it "resets the clock" and won't alert until the conditions you have set.

Well i hope that makes sense. if not i think it will once i post the results.

For those reading this who are looking to enable these options, ask yourself 2 questions.
1. What type of threats are here. Instant on, Constant on, Rear attacks.
2. While driving through areas with falses, how strong is the strength meter, and how long of a delay do i want.
With these questions answered and the results, you should be able to set it up like you want and still be protected.

Its been my understanding the the filtering modes of "l" and "L" only affect X-band performance.

I wouldn't expect that you would see any operating performance differences with K-band detection merely from changing between all three modes.

Just sit in a parking lot with plenty of K-band door openers and play with the modes. If there's any effect at all that's where you would see it. My non-POP unit cancelled out some K-band signals fairly consistently. Haven't tried it with the upgraded version yet.

Ah, you must have been looking at the outdated book. :wink:

It does affect it in both modes if you change option "7".
This will enable features b thru G.
It states in in Mikes report (#3 i believe) and i verified it with VR, here's an excerpt from the email:
"Option 7, which, as the instructions say, automatically mutes K-band alerts, does indeed work differently under the Logic and
Advanced Logic modes. Advanced Logic will mute the K-band down to nothing, but Logic will continue to report K at whatever
you have your fader ring set at. In other words, Option 7 works similarly to how regular X-band works in Logic and Advanced Logic. There's a section in the manual that explains how X-band works in Logic as compared to Advanced Logic."

Now just to give you an idea, on the highway test i lost over 3.5 miles of alert in instant on testing, depending on the settings, so yes there can be a BIG difference.

Besides, do you really think i would spend all this time, money and energy for nothing. For what i've spent on gas alone, i could have treated the neighborhood to a coating of Veil. :wink:

brick,

The man, himself, I believe, answered this very question to either Steve or Sethy on this forum and directed the answer to his operation manual which mentions X-band only.

I would refer you to the post, but this forum is beginning to get pretty large now, making the search more challenging...

Glad that finally got cleared up, I've been wondering what the story was with l/L and options b-g...

Can't wait to see the results. :wink:

[RacerX]

Anyway, for those that believe me, here's a quick video clip to show what i am talking about.

I did this with a k band door opener for simplicity, but a k band radar gun will do/show the same results.
What you will see is a pass in "A" mode, then a pass in "L" mode, with option "7" changed, b,c,d with a 30 second delay, and options "E", "F", "G" changed.
Enjoy.

These are the same clip, one just higher quality.

Okay, the moment you have all been waiting for. (Well hopefully at least a couple of you. :wink: )

The test results are finished.
I will upload them shortly and start a new thread for it.

Here it is.
