........at least on the highway. I've mentioned a few times that I have always run L mode. After updating my gen 1 with TMF2 I decided to test my old thought process. I found a K band speed sign at the top of hill on which the incline is a curve. In L mode the K muting i put in place doesn't come in to play because V1 isn't reporting the weak signal anyway. In A mode V1 reports halfway up the hill before the curve. In L it reports at the top after the curve. (The speed sign is on flat ground not pointing downhill)

With t filter off the speed sign comes through as 3 signals. Hmmm.

I'll go back later for a little l run.

Why do I bring any of this up? Well I found two deputies near my house running Falcon K with reduced power. We'll just say my reception of their signal was a little close for comfort.

If it's any consolation, you're not the first to see this. If you're running against Falcon HR the TMF2 filter can kill range to a dangerous degree. And it's not only the V1, it's the ProM with TSRej and Unidens with certain FW versions and TSF, Escorts and probably many other "quiet" detectors as well.

I currently view K band, particularly low powered K as the worst threat I face. At least until someone dusts off an old X band unit and begins issuing nasty surprises.

Low powered K seems like a good place to hide. I was so used to using the V1 only on road trips. On the open road I haven't seen the low powered stuff., not K.

I’ve tested my V1G1 in all modes against BSMs and found it to have almost no impact between L and A against all the BSMs the gen 1 wasn’t designed to filter because they probably weren’t around then. It’s on latest hardware but not firmware (Mike’s fault on that one) but it’s the same filter levels so firmware isn’t the cause of this. It might have only a marginal improvement against some Buicks but it’s not worth it. So, I run A mode all the time and I’m good with it. No issues so far. 🤞

FWIW, in 16 years with the Gen1 (before I went to eUro mode with Custom Sweeps) I ran in lower L mode.

Yours is on the latest firmware it can be for your hardware. There is no fault here.

Let’s agree to disagree. When you pay someone for a repair and ask them to also make sure you’re on latest firmware and ask what else it’ll cost and they say just the repair cost and they’ll handle that as well and then they don’t do it, THERE A FU***** PROBLEM. Regardless, the firmware after mine and even on newest gen 1s have no functionality difference that would help falsing, so it’s a moot point, but it’s the principal of the matter. This is why I’m never surprised when I hear about some issue coming from them.

Care to elaborate on the Uniden part with more specifics!? Thanks! :)

Although there may be some exceptions, generally, Unidens starting with FW 1.46 and newer, have more filtering going on with TSF. Against certain guns, (HR's Decatur Genesis, RP-1, maybe others) this causes delayed alerts and also translates into range penalties IRL. It's why I never recommend TSF as a hack to reduce BSM falsing. I believe it should only be used if you need it against Traffic Sensors. or if you don't have K band in your area.

1.37 doesn't suffer much if any of a penalty with TSF ON........ironically, it just doesn't work well against traffic sensors....LOL

Thanks for the clarification! I don't ever use TSF for either the R1 or R7 as the locals like K band around here and sometimes even I/O in K!

Was TMF2 turned on when you got it back?
That's ^^^ the extent of the firmware upgrade from v3.894 to v3.8945. I suspect that's exactly what you got. It feels like you are hanging a lot of frustration on a very minor technicality.

As mentioned before, you could not have gotten v3.8952 with the hardware you have so that's off the table.

Regardless, the firmware after mine and even on newest gen 1s have no functionality difference that would help falsing, so it’s a moot point, but it’s the principal of the matter.
What changes do you think exist between v3.894, v3.8945, and v3.8952? They are all functionally the same. Please look into this a bit and let go of the misunderstanding that you didn't get what you wanted.

You didn't have to post any of this junk here; yet you did. This thread was about @biolink deciding that big L might be too restrictive for his particular needs and you are trying to sway it to something unrelated.

Create a thread specifically about your complaint instead of bringing it up in other people's threads. Maybe post your serial so that we can all check and see what's what.

I’ve tested my V1G1 in all modes against BSMs ................
Ok, my comment here is I am not talking about BSM. My point is that L mode In the words of Valentine: "In Advanced Logic mode , X- and K-band bogeys the Analyzer determines are not threatening will not be reported at all. " Because of this, I used "L" as a way to quiet it down. On road trips it was not an issue because I encountered LEO in KA at greater distances and never saw the low powered K band. I'm just doing some testing to validate if my previous use of "L" mode is effective or risky. In my test today I am making the observation that my k band muting is moot, becasue V1 is not reporting the signal until it at the threshold of my muting. " In Logic mode , X- and K-band bogeys assessed to be too weak to be threats will be reported at the Muted Volume. " So if I use little l and let it report sooner, my K band muting will work. That's all.....I'm not griping about firmware or somehow saying that VR is at some fault here. I personally see brilliance is his set up. It is up to me to figure how to use V1 and not up to VR to figure out how I want to use it.

Right, I get that. What I was trying to say is that most are running L on the gen 2 to help with BSMs... really that’s about the only reason anyone thinks about changing modes. If A mode had the same level of filtering, everyone would be running it. And yes, I get that the “filtering” is the same and range is really the change but there is some log change as well in the gen 2 units. What I was getting at is, if there’s no benefit to running anything other than A on your gen 1, why even bother? Based on your testing, it’s only hurting your low power K detection of legit threats, so might as well leave it at A. In my everyday use experience, L or l made no different where I drive (same spots) to get rid of falses. It behaves the same, so A it is. Or do you not agree?

I’ve played with all modes and looked at all the tests and come to the conclusion use A mode and let JB or V1D sort it all out. Would love to play with a low power gun.

I disagree. l or L affects reporting, not detection. "Be assured that the Analyzer has years of radar experience. It always operates the receiving circuitry at maximum sensitivity" ........." In the Logic® ( l) and Advanced-Logic® (L ) modes, you are deferring to the internal computer which will use its own logic to screen bogeys before reporting them to you. "

However, I can't say whether l or L make a difference where you drive. I'm just considering not using L so I can hear about K sooner.

Was it over when the Germans bombed Pearl Harbor??
SO the thought process is to run A and let JVB1 do it's thing? I am running l with JBV1. I have no real road experience with the V1G2 so, I have to base it off of what I learn here.

Like I've told you, I'm running A mode with K verifier with JBV1 with zero lockouts or anything else from JBV1! I always start with no filtering and then add what I need. So far so good!

So, you're full wide open. Not even the lockouts? I mean I have no issues going to A so long as JBV1 can function in that mode.

Still learning this set up. I love it though. But much to learn.

Yep WIDE OPEN! I didn't think I'd be able to run it like this, but in my area it's perfect!

I'm also running A mode, KV on, no box mutes and rear/side K muted.
I think I could even run KV off, but there aren't many Redflex vans around, and when there are I get 180 - 200 metres warning so there's no point.
Life is much simpler without mobile K band.
