Using V1 in small L or Big L

[vspacheco]

I dont know if it is posted somewhere in here, but I could not find it. I have a question about using the L/l modes. Do the V1 looses sensitivity or reaction time to Ka when using one of these two modes?

Thank you.

Logic modes have no effect on Ka band. Only X, and to a lesser degree, K (unless you enable the various K mute modes in the programming).

And to add, it doesn't cut down on sensitivity at all. The only thing that changes is the way the K and X alerts are presented to you.

I was under the impression that L only effects X by default.

Computer Modes: A new way to interpret alarms
In the All-Bogeys®
( ) mode, all bogeys will be reported
as soon as they are detected. Use your judgment to decide
whether or not they are threats.
In the Logic® ( ) and Advanced-Logic® ( ) modes, you are
deferring to the internal computer which will use its own
logic to screen bogeys before reporting them to you.
In Logic, X-band bogeys the computer judges to be
non-threatening will be reported at the “muted” volume. If
they become threatening, the audio warning will upgrade
to the “initial” volume before you are within radar range.
In Advanced-Logic, X-band bogeys that the computer has
reason to believe aren’t radar will not be reported at all.
One exception: To be failsafe, the computer will always
pass extremely strong signals along for your judgment.
This mode is particularly useful in metro areas.
The computer is smart: It never operates the receiving
circuits at less than maximum sensitivity and it knows that
Instant-on is a greater threat than ordinary radar. So it will
always warn you immediately at the “initial” volume when
those radars are detected, no matter what mode you’ve
selected.

That part of the manual hasn't been updated in years. Back in the days of the 1.7 V1 it was true, logic mode only affected X. In the 1.8, there is a degree of K band filtering in logic modes as well. I've seen this myself when switching between A/l/L modes when near door openers. Some of the weaker K bogeys drop when I switch to L, and come back when switching to A.

Is there any official documentation about this? The manual I got with my new V1 straight from VR a month ago says the same thing.

Since these tests were done in '05 with a thread at the time showing a loss, has it changed with the updates and newer V1 versions? I like running big L but I don't want to get whacked with a ticket if there is a loss.

The local LEO's around here DO use K band almost all the time.

Excellent question!

The test that was done showed the alert distance between A (All Bogeys Mode) and Big L (Advanced Logic Mode). It is true, if running in Big L that you will experience a loss of distance, because the small non-threatening alerts that are weak don't appear at all until they become stronger. Running in Big L is like running with a City setting on another detector. It doesn't decrease sensitivity, but sets a higher threshold of when the detector will give you warning i. e. when the strength gets halfway or so.

If you use Little L, you still see all alerts so essentially you won't lose any distance or alert time. Running in Little L lets you keep the V1 more quiet, without keeping you in the dark from alerts.

And to answer your original question, I don't really know for sure. The antenna is the same as it was back in 2005 according to the FCC ID's, but for sure the firmware has changed since then. I really don't know by how much, but I'm willing to guess that it'll be close to what it was back when this test was taken in regards the the alert suppression in Big L mode.

What you really need to know: Big L causes significant distance loss on alerts except Ka.

So if I can understand correctly, Big L only affects X and K band? Ka band remains unaffected?

I just bought a new Valentine one and sold my GX65. Since I am new to the V1 world, I am questions on the right setting for me. I know this has been discussed many times. I am in DE- no x, very little k - mostly ka. Can you give me a quick setting summary or show me the links here? Thanks. I want to have a fairly quite detector , but love the arrows and all the features of the V1.
