Since this is a thread about both Uniden and V1 I'm going to post what happened to me on the way home today with my R1/Redline-O combo against 34.7! We've all been bitching about our V1G2's ghosting during alerts, myself included, and for good reason I might add! The last time I got shot at close range with an I/O shot last week from one of "NC's finest", out of the corner of my eye I thought I saw an extra bogey light up in my R1's box. I thought maybe I was just seeing things and just forgot about it. Today on my way home it happened again at least 10 times! My R1 does this quietly so unless you're looking for it you won't notice it. It went as high as 2 in the box plus the one it was showing against the 34.756 I/O shots he was shooting while I was behind him for about 15 miles or so before he turned around! All of you with a R1 or R3 take notice and see if it happens to any of you as well! This could have been happening for a long time and I just never noticed it because the audio doesn't change, it only shows up in that tiny little box! Looks like the V1G2 is not alone in this! It's just like when you pick up several door openers on K band, only it's just one signal showing up as more.

See if we can get some good images on all testing and see if this occurs with the R1/R3 with the others, since we streamlined that testing course.

My dash cam of course is focused on the road and not on my R1 which as you know is at the top of my headliner! This will be easy to get with a phone however now that I'll be looking for it during testing!

So I had a little bit of time to do some Ka testing yesterday. I wanted to do some off-axis testing of the V1G2 and the R7, given folks' continued raves regarding the V1G2's off-axis Ka abilities. I used the wife's minivan as a radar car. I used the same course I used for the Falcon HR testing a few months back. It's an off-axis situation with some good foliage obscuring things until the kill zone.

THE DETECTORS

V1G2 – (fw 41019) – A mode, KV on, CF used, X-Band off.

R7 – (fw 134.141.114) – Hwy Mode, Ka segged 2/4/5/6/8, K wide, KF on, TSF on, K Block on, MRCD off, X-Band off.

THE RADAR GUN

MPH Python II FS with Ka antennas tuned to 34.7, 35.5 and native 33.8.

Basically the same sort of setup as I did with the Falcon HR, except the antennas were pointing out the front of the car, held unto the WS with a rigged up Escort sticky cup. Radar car was in the same place. Kill zone was the same place. Photos below from prior Falcon testing for illustrative purposes.

THE RESULTS

I'm going to do this like I did with the Falcon HR, just post the still pictures of the first alerts. No charts or graphs. This time I did reset my dashcam date/time so the date/time stamps are in the pictures are accurate.

Ka 34.7 Results

R7 - Hwy, Segged 2/4/5/6/8, Ka filter off, K Wide, KF on, TSF on, K-Block on, MRCD off (Runs 1-3)

COMMENTARY
  • Not much to say here except my V1G2 and R7 are pretty evenly matched. That said, my V1G2 did edge out my R7 by just a little bit on each Ka Band overall, I think.
  • V1G2 still seems slightly more consistent than the R7. Somewhat strangely, each detector had one "lesser" run on 33.8.
  • I'm still waiting to see my V1G2 beat my R7 by more than a little. Hasn't happened yet in any TXCTG testing. Maybe I have a hot R7 or a cold V1G2.
FINAL THOUGHTS

My R7 and V1G2 continue to be pretty evenly matched, with the V1G2 just edging the R7 out in most cases. Maybe I need to send my R7 to @Kennyc56 and @VariableWave for testing, or maybe they need to send me one of their "killer" V1G2s (not sure I can pry Kenny's V1G2 out of his hands, though...lol).

As always, remember this is just one test. Don’t base your opinion of a detector on just one test. You need to look at various tests, by various people, at various times, on various courses to try to get to a complete picture of a detector. So make sure to look at as many tests as you can, and find out as much information as you can, so you can have an informed opinion about a detector.
Yep, this is one test. In today’s becoming cluttered Ka space, the Ka filter should be on the R7. May not make much difference in off axis performance. Also, nice pictures, however, would like to see the full display of the R7 when it alerts. Same for G2. Not complaining.

In my experience, agree they are fairly even matched on off angle. The G2 beats the R7 by several seconds with seat of the pants street running at popular donut break off to the side LEO locations where they run C/O. I run the R7 Ka filter on. I also am not running your firmware. IMO, the G2 seems to have better handle on off axis with decent reflectivity. Same for less reflective locations. However, two off axis I have had with R7 in a low reflectivity off angle, AND me on other side of a low rise, were moonshot like hits. solid hit too. The G2 will burp alive at same spot. Not the same alert cadence.
Post automatically merged:

This is what I am kind of imagining. Obviously the RF projects in a cone but taking just the center projection there would be something like this.

The angle of reflection should be equal to the angle of incidence. Since it's a curved surface, we need a "surface" tangent to the curve and coincident with the point of contact to calculate the angle from. Anyway, if I did this right (don't pay attention to the linear dimensions as they aren't to scale) that would put he intersection of the signal and the car's path at approximately the point circled in green.

Of course w are going to get further reflections from the conical nature of the signal but most of those will have to go through the woods on either side. It's possible we'd get a reflection from the first house on the left there though.
Agree... With that said, this testing location is classic for a real life encounter By a crafty LEO. I like how this test was set up. One of many good ones to trst this sort of thing out.

Thanks for doing the test and sharing the results. Before the G2, the G1 was scoring mid-pack for Ka in many of the test results reported here. If the G2 can hang with the R7, that’s a good thing- it seems they very close in Ka (K is a different story). I don’t think it’s a hot / cold issue. When the G2 was announced, I would have been happy with R1 Ka performance, which would have been a huge improvement.

there have been some portable Ka signs around town, and I have noticed the G2 is very consistent without any noticeable outliers (tight groups for gun enthusiasts). It alerts in about the same spot every time. Consistency is probably more important to me than an occasional Mars sniff. My R1 seemed a little less consistent with more outliers than the new G2.

Testing seems to indicate the V1G2 is more consistent than the R series. And while they are close on Ka, testing does seem to indicate the V1G2 is a bit more sensitive on Ka, at least on 34.7 and 35.5. Still not quite convinced about 33.8, but really doesn't matter as 33.8 should be the easiest to detect of the three, and you should get plenty of range with either.

Alright guys check this out in lynchburg virginia in the mountains the uniden R3 did this something you guys will probably call me a liar on.....😂 And I won't be made at y'all if y'all do call me a liar... This is what happened and I wish I could have had a camera 📸 so y'all could have seen it.. I was in my company's F-150 work truck, I got got one blip then all of a sudden the one blip stayed blipping but with only 1 or 2 bars flashing it stayed that way for a long while so after 2 miles I told my co worker to keep an eye on the odometer for mileage, now in the meantime we were riding and riding finally after 11 MILES we saw two sheriffs parked at 2 schools one facing northward and another facing southwards.. both were running Ka band.. so that was mind blowing the reason is this through all the turns and hills and valleys the R3 never stopped beeping...I can't explain what happened but I haven't seen my R7 reproduce that, check this out I had a Bel vector 985 that pinged va state police from 9 miles out. It could be these are freak accident detections, I don't know but I find it interesting and would like to test my R3 and if I can find a Bel vector 985 I'll test them both and post the results here on the forum next time I get with Kenny and variable wave.. I do personally believe that detectors though the same makes and models are on occasion tuned stronger than others of the same make and model. By the way when we did get to flat straight roadways I never saw anyone ahead of us also it was 3a.m. in the morning... Plus I had waze on not for police but to see the road and terrain, things such as curves, straight stretches, etc..

Hello Walt! I don't think you're a liar, far from it my friend! @VariableWave and I can't wait to test with you again! You get brought up every time we get together! He keeps telling me about some of the roads that you 2 found in your area that will be great for some testing.

Hi Kenny!! Yeah man I'm looking forward to hanging with y'all I'm curious to put the legend to the test.... The legend is the R3 LOL!! I've got the R7 too but I'm gonna keep it real the R3 may be stronger as crazy as that sounds... and look something else is crazy one day my son was in front of me with the R3 and I was behind him with the R7 and he got alerted a couple of seconds earlier than me FROM A REAR DETECTION, unbelievable, my arrows finally started pointing backwards to KA band. I know it sounds unbelievable but it's true..y'all gimme a call when yalls are ready...

It is possible with the R3. back in 2018, had 11-12+ mile alert in Nevada. Couple of bends in the road. Mostly flat. Ka. Forget the segment they were running. Posted it in RDF someplace. With all the other devices I use, I keep this one for sentimental reasons. Used to use it for rental cars when needing long range.
