So I've been meaning to get some testing in with these new Unidens for a little while and finally had some time this week to go out and do some runs. The course is the same one I used for the previous affordable radar detector test.

The objective of this test is simply to see whether or not the Uniden LRD950 with its LNA more sensitive than the cheaper LRD450 and LRD750 that don't have the LNA. If this test shows us that, that's all I'm hoping to achieve here. This isn't intended to be the greatest test ever. It's a simple backyard test. :)

Now looking at this test specifically, while I used the same course as last time, the test this time was actually harder on the detectors. Why? Well instead of mounting the radar gun in a vehicle like I did last time (which is what you should do... heh), this time it was just me by myself and for the radar source, I put the Stalker II in a box and set it on a ground, tucked behind a bush so people wouldn't see/steal it. :D

Because the gun was lower to the ground and partially obscured by grass, it really cut down on range and so detections will be shorter than when the gun was mounted higher up. Now obviously this isn't going to be a realistic mounting position in real life and cuts down on the gun's ability to acquire speeds to, but it works fine as a fixed radar source purely for testing. I had to tweak this and adjust the orientation a bit so that I could get some reasonable detections for this test.

As for the course itself, here's the map I used last time which is still relevant, with one change.

Course Map.jpg

There's two main detection points in this course. The "good" one is labeled "gap" where there's a clear line of sight view to the gun. This one's farther away so it's the better location to alert in. The closer "bad" one is labeled "second pullout" as you get closer to the radar gun. The gun itself is sitting at the first pullout labeled "radar gun."

The detectors that did better typically alerted somewhere in the gap and the detectors that didn't alert as well picked the signal up somewhere around that second pullout.

Since I was only running one radar gun for this test, every detector was run three times to test for consistency, repeatability, and hopefully weed out any outliers and freak detections due to traffic, good or bad.

For each detector, I'm going to tell you where it alerted for all 3 passes and then show you video of all the runs.

Uniden LRD950

The LRD950 set the pace by alerting in the gap for all 3 runs. So far so good. We're getting consistent, repeatable, reliable performance. This is what I like to see in a detector.

Uniden LRD750

The LRD750 didn't do as hot as the LRD950. While it was able to alert in the gap on its second pass, for the first and third passes it alerted in the 2nd pullout. So it doesn't have the same level of performance and consistency as we're seeing with the LRD950.

https://www.youtube.com/watch?v=WFGhM___bxE

Uniden LRD450

The LRD450 actually performed very similarly to the LRD750. It alerted at the start of the 2nd pullout, then did well by detecting in the gap, then it had a poor detection at the end of the 2nd pullout.

https://www.youtube.com/watch?v=3lKAfLg5jsI

So it's looking like there really is something to the LRD950 with its LNA. Its performance really is better than what I'm seeing with the two other detectors. That's the main thing I was hoping to test and find out. Everything else at this point is just gravy. I brought a bunch of other detectors to test out for comparison purposes including the Radenso Pro, V1, RX65 M4, Cobra SPX7800BT, and Max2. Let's start running through the next round of detectors.

Radenso Pro

This detector I was excited to test out again. It performed very well last time. Since then I've received a firmware update which changed some things and performance was tweaked/improved. Awesome.

There's been two changes relevant to this test.

1) Because of the inaccurate frequency reporting, they've adjusted the way the signal displays. If it's 34.7'ish (ie. 34.5xx, 34.6xx), it'll display 34.700, even if it's not able to accurately determine the correct frequency. However, because of this, I'm now able to run Ka Narrow instead of Ka Wide (band segmentation, essentially) and not sweep the entire Ka range. This really helped for other detectors and I'm excited to see how it compares here.

2) For some strange reason, the detector is actually more sensitive if you turn the frequency display off. There's about 0.5 dB of difference, sensitivity-wise. They're not sure why yet and it's something odd they're working on, but since this is a way to boost signal strength more, I tested this out as well.

Sweet. So with the Radenso Pro I ran 6 passes

Passes 1-3: Ka Wide, Frequency display on (same settings I used for the last test)

Passes 4-6: Ka Narrow, Signal strength bars on (settings for maximum performance)

Once I started doing the tests, I was a little surprised by the results. I was expecting nice and solid detections from the Radenso Pro, but every single time it alerted somewhere around the 2nd pullout. No detections in the gap farther from the radar gun.

https://www.youtube.com/watch?v=G9ibUkA7quk

What's going on? Is there something wrong with my setup? Is it the detector? The firmware of the unit was updated between the previous test runs. That could have something to do with it.

I'm *always* looking for anything wrong with my testing methodology and reasons to invalidate my own testing setup. Is it possible that power output from my Stalker II was dropping over time because it's running on battery? The gun does have a really long run time on battery. I had fully charged the battery previously. Only 18 minutes had elapsed between the last LRD950 run and the first Radenso Pro run. I started transmitting the gun about 30 minutes before I got to the Radenso runs.

For the sake of checking my math, I put the LRD950 back up and this time it alerted just before the second pullout. hmmm... What's going on here? Is the gun starting to reduce its power output? Is it possible that that was simply a poorer detection by the LRD950? I saw some inconsistency with the 450 and 750 where sometimes they had better detections and sometimes they had worse detections so it's possible that it's the detector and not the gun.

I'm not entirely sure and honestly I don't think it's gun, especially having only been transmitting for 30 minutes and knowing that battery can easily run for hours and hours on end. It's hard to kill that battery. I only charge it because I know you're supposed to regularly, not because it gets low.

In any event, let's keep going with the testing.

Valentine One

With the V1, detections resumed in the gap, the good area. I was getting longer detections with the V1 like I was getting with the LRD950. Awesome. If that's the case, maybe it really is the detector and not the gun. Previously the Radenso did well on Ka band, either running neck-and-neck with the V1, or even beating both it AND the Redline. This time the V1 was consistently able to beat the Radenso hands down. Keep in mind that the V1 was running after the Radenso so if the power output change is a real thing (and again I don't think it is), the V1 would have technically be running with a potentially weaker power output, only solidifying the V1's runs that much more.

So for the first two runs, the V1 did very well. It alerted in the gap both times. One of the hallmarks of the V1 I've seen in testing is its consistency, and this makes it easier to test.

https://www.youtube.com/watch?v=o0xm6vmJkwE

During the V1 runs, there was an SUV parked in the first pullout where the radar gun was. Was it interfering with the signal, good or bad? Potentially. One of those variables you can't control, you know? It is what it is.

On the third run, I see the SUV driving away as I'm approaching the radar gun, but my V1 isn't going off. No alert far away, no alert close, no alert as I pull into the first pullout, nothing. Oh crap... I hope that guy didn't just take my radar gun and run! He didn't seem to be eyeing me or the box previously when I'd pulled in. He was messing around on his phone.

Thinking that he might have taken the gun and seeing him driving away, I quickly pulled into the pullout to go check. Box was still there. Good. Did he open it up and take the gun? Nope, gun was still inside. Phew! Okay, so what's going on? The gun was still powered on. It turns out that the rubber band that was holding the trigger down had rolled off and the trigger was no longer depressed. Thus the gun had stopped transmitting.

Okay, time to set it back up. Now I'd seen from positioning the gun at the start of the test that the orientation makes a big difference. (I saw the same thing last time too.) I set the gun back up as best as I could and on the two subsequent runs, the V1 did really poorly. Both times it alerted closer to the second gap.

https://www.youtube.com/watch?v=UInhNrqVqwE

Dangit. Looks like having to reposition the gun killed my test and I won't be able to continue this test since I can't position the gun exactly the way it was before. Because of this, I wasn't able to test the rest of the detectors including the RX65 M4, Cobra, and Max2. Oh well. Those were just icing on the cake.

Anyways, like I said earlier, the whole point of the test was to find out about the Unidens first and foremost, and that I feel like has been accomplished. I do have some doubts given that the LRD950 had a worse detection on its 4th run, that one I did after the Radenso to check my work, so that makes me wonder. You could always do 10 runs to get more samples and data points in, but you gotta balance that with everything else too, you know? ;)

Either way, from what I can see so far, it does look like the LRD950 is performing better than the LRD450 and LRD750 and this would line up with theory given the LNA (950) or lack thereof (450 and 750).

So think of this as just one set of data points, one test to consider.

Upcoming Tests

A quick heads up as to what to expect next: @hiddencam and @OpenRoad will be testing these detectors out as well. hiddencam graciously offered to conduct some of his excellent radar detector tests since he has some nice long straightaways to test on that work really well for testing. OpenRoad will be doing some more stew tests with these detectors. (I had high hopes for the Radenso, but I have my doubts now after seeing how it fared on 34.7 in this test. Either way, we shall see...)

The backyard testing continues. ;)

Thanks for your time. I remember having to wait at least 6-8 months for any radar testing back in the day.

heh yeah, it definitely can take time to acquire equipment, get things scheduled, get the time to go out and test, etc. This took me a couple weeks to get to and even that felt like half an eternity. :p

The more testers we have in play, the better. :)

You are awesome Vortex!

Is the 450 still a good choice in your opinion? Does it provide good range for detecting radar far before the radar can obtain my speed?

Do you think based upon performance, it is worth an extra $150 to upgrade from the 450 to the 950?

Lastly, do you believe the Unidens are on par with V1 or is it worth the extra $200 to upgrade from a 950 to a V1?

Again.....really appreciate all the time and effort you have put into this. It has sure been interesting!!!!

I don't think the 450 is a good choice for a detector at all. If I were really tight on a budget and couldn't afford to get a better performing unit, I would go with an 850 or 950. Both are much better options.

awesome testing, I liked it! Too bad about the repositioning but it makes sense, I was really looking toward to the Redline and see how the beast would have done in that test.

Yeah I don't think there's enough info yet to say if they're satisfactory. When we get more tests in with other "affordable" options like the Cobra, RX65, Whistler, and whatever else, we'll have a better feel for how they compare to the competition.

That said, I'm never a fan of skimping on a RD. I know it's only $50, but still...

Excellent testing! Thoughtful and honest analysis, no surprise coming from you! Enjoyed the read, and Very interesting results for the Unidens!! That course looks like a good one to show some good separation.

Concerning results for the Radenso Pro. Hopefully that's just a glitch.

Bummer about out the elastic band and the havoc it caused haha. Hate when that happens.

I'm really looking forward to testing them all in a couple weeks on the long course!

I agree Rags, just having the Freq display to quickly identify ka falses from leaky rd's and the better performing LNA's would be worth the extra coin to me.

I would recommend the RX65 for folks on a $100.00 budget and the 950 for people on a $200.00 budget. Both are solid performers for the price.

Yeah, that should be interesting. Are you going to have an belscort M4 in the mix? Seems like it is kinda the competition for these lower priced Unidens. I'd like to see how it stacks up.

Yep. We'll have an RX65 M4 there too. :)

And it won't be my Redline that had faulty Ka band detection, but surprisingly good k band detection at your last test...I sold that one. My bad, I sold my original Redline, but you will get to see what my second Redline can do after a check-up at Escort after the faulty Ka antenna issue.

@hiddencam - so can you give us a rundown of the RDs to be tested and the radar guns to be tested against yet? And when are you conducting the test? Weekend after this coming? Sorry if I'm jumping the gun...
