Conclusive Test - V1 vs. Bel 995 - on Ka and K bands

[AirMoore]

You do know your comparing a 270 dollar detector to a 400 dollar detector right?

Sounds like he bought the both of em, don't it geniOus.

Der Dee Der (mencia)

Well he obviously doesn't understand this... because he is happy his overpriced V1 is doing better, well jeez... it should be it costs more.

Radar D*ck, listen your a zombie at its fullest, and you are rather mindless in your posts... and I know all the recent problems with VR and V1's have you crying in a corner, with your mullet the only thing people can see... but don't take it out on others.

Resorting to name-calling? I thought you were above that.

As for being a Z(V)ombie - Yeah, right.

SMD Airhead.

Using your logic the STi should outperform all of 'em - or is the extra $$ just for stealth? The V1 costs more than the RX65 and the X50 too, so does your logic not hold true universally? Please explain.

Considering it took 1,000 dollars (or in the area I believe) to make the V1 immune to Spectre 3 the STi is doing really well, and the 1,000 for the V1 shows the extra money is needed for stealth. :wink:

Jim can confirm this. If you run the V1 and RX65 besides each other and while detecting the same cop radar the V1 can be "J"ed out by the RX65 so this may the same with 995.
Also good on you for this thread that's what a man would do :wink:

I have video to prove this to be incorrect. I have video of the v1, rx-65 & x50 all running together. without any problems at all.

You know, I had the V1 and the original Escort Passport running side by side, and to my shock niether seemed to be impacted AT ALL (I was just testing on a speed sign once, and figured Id see how much the V1 gets messed up... it didnt at all... not even 1/10th of a mile)... I of course don't run them together normally... just was a little experiment. With that said, my x50 and V1 really dont like being run together though.

Confirmed :wink:
We did shoot some video @ GOL '05 where they all worked together just fine. But, they CAN and DO cause each other problems. It might not happen all the time, possibly only when the sweeps of the different detectors coincides in a certain way, or when the Belscort units go through an "internal" self-cal (that does not show self-cal on the display) as they supposably do this periodically during normal operation (last I heard was every 8 minutes or so).

Under test conditions, detectors should be run separately.
It is nice to run multiple units together like we did at GOL to see what happens, but IMHO this should not be the basis for test results.

Yeh, I am the one that started the other thread on 15 years of V1 ownership and going to sell all my stuff on eBay, thinking the Bel 995 was just as good.

Well......... as I was boxing everything up, I took a few hours to do some final testing. It turned out to be very informative.
A LEO was using Ka in both instant and constant-on mode. He sat there for about an hour. Nice. Further down the same road is a "this is your speed" sign on K band. What a setup! It's a busy road so I did not stand out too much by making multiple passes. I made 18 passes (9 round trips). No I am not kidding. I wanted to be sure what I was seeing was repeatable (it was).

I had a V1 3.826 (POP on, Advanced Logic mode, large L) and Bel 995 4.5 (POP off, Highway mode) mounted high on the windshield, but below the tint strip. On various passes I used both units at the same time and one at a time, to rule out interference between units from their LO's. I also swapped positions. I covered all the bases to compare the units.

K band - sometimes one unit would alert slightly more than the other, but it was random. I am convinced they are just about equal.

Ka band - Sheeze! You got to be kidding. I thought the reviews said the Bel was just as sensitive. Kids, that's not the case here. In every single pass, the V1 alerted a LOT sooner than the Bel 995. The PSL was 40MPH, and at that speed the V1 would start alerting a at least 15 seconds sooner. This is critical time to slow down. This is critical sensitivity needed to detect Ka in instant-on mode being used on other targets ahead of you.

40MPH is equal to .01111 miles/sec. So, 15 seconds at this speed is 0.17 miles. That may not sound very far, but look at a clock for 15 seconds and it's a huge difference.

Has anyone else done a side-by-side comparison like this? Let me know your result.

PS, the V1 did J-out once on the LEO. Other cars were around. One of the probably had a Cobra RD. However, it had already given me plenty of notice. Not a big deal to me, it's VR way of dealing with POP. On the Bel 995, if I enable POP I get random alerts, that's a lot worse, so I keep POP off on that unit.

I am pretty excited about these results and wanted to explore the J-Issue more. I went to the local PD parking lot. Found one patrol car with Ka band on. This is not uncommon in this area. As I circled around, the V1 J'ed out after approx 45 seconds of alerting (at or close to full scale). After J'ing out, it would not re-engage the target until I either did a POR (power on reset.... ie; restart the RD) or if I drove away and came back after a few minutes. I was able to repeat this 3 times. When the V1 J's out, it holds it that way until the radar signal is gone for some time. That means you could be following a LEO down the road, and if the unit J's out it will remain that way until you part ways.

I hope this information is as interesting for you and it is for me. Our city uses Ka exclusively, no other band. I volunteer for the PD so I have direct knowledge of that. So the Ka range mentioned earlier is critical. Any comments on what I see with the J-issue? I can absolutely confirm it's occuring on a valid radar gun (The Stalker DSR-2X and Stalker II is used here.... and they are also manufactured by Applied Concepts which is in this city).

OK, I feel like I'm on a roll here ! I returned the Bel 995, and went testing again. I found a LEO (working the same stop, what a surprise), and parked in an adjacent lot. Like I mentioned before, all the patrol cars here use Ka. He had his on constant-on mode. I could NOT get the V1 to J-out. The signal was anywhere from half to full strength. I repeated this about 5 times. No J'ing out.

Why is this? I now believe it's because I was leaving on the Bel 995 when getting a full-scale signal from a LEO. The interference from the Bel 995, under these conditions, was causing the V1 to J-out the valid LEO signal.

I also more accurately measured range of the V1 3.826 Ka response. I am getting 0.9 miles consistently.

The only question remaining is why are my results (V1 surpasses Bel 995 by a wide margin) not consistent with this test http://www.guysoflidar.com/radar-det...testjan06.html ? Could it be there is significant difference between the Bel RX-65 and Bel 995? They both have the same firmware and probably share the same PCB, the RX-65 just has the international mode.

Because, that test was set up in a manner that allowed for way too much variation in the results. The very best was to test is in an over-the-hill situation, where the hill/earth acts as a broadband attenuator for the radar. However, because of convenience, time constrains, etc etc we chose to use that test course, and used "aiming attenuation" and aimed the radar at a very steep angle. On one hand, the test could have easily been a real-world situation, where for example an officer is waiting to pull on from a side street. But on the other hand, it wasn't a very good guage of the relative sensitivity between detectors.

IMHO, our 2005 test was a LOT more conclusive, because we used a hill. I think we would be very hard-pressed to try and dupluicate the results of our Jan '06 test.

BTW, I edited your link so that people would know what it was before clicking on it. No need to use "tiny url" on the board, unless the link is extremely long. Also, having the original links will help out when people search the archives in the future.

Jim, thanks for the feedback. I agree, the test at http://www.guysoflidar.com/radar-det...ctor-test.html more closely resembles my experience, with the exception that the Bel 995 had such poor reception in my tests.

Anyway, great site you have there !

I am surprised you guys can get the RX65 and the V1 to play nice? I've tried to run them at the same time, but it seems my V1 picks up the Bel no matter what I do.

I did run them once at the same time on a speed sign, but I am 100% sure they were interfering with each other. When I ran both RD's at the same time I got very inconsistent alerts.

The strange part is my Bel doesn't cause my V1 to "J" out ever. However, the V1 picks the Bel up on X and K. but never Ka. Maybe this is why it doesn't "J" out.
