I took the R7 on a 200 mile round trip today and unfortunately got almost no Ka band encounters, although I saw dozens of police cars. (It seems that when you're running with a new detector all the LEOs decide to shut off their radar when you drive by.) Hopefully I'll be able to get some good Ka band encounters to post here next time I drive with the R7.

I did, however, have a few slightly odd encounters and I wanted to post them here to see if you guys can tell me whether the performance I'm seeing is normal. I put all three clips into one video to reduce clutter in the post.

1) K band speed sign. Detector did not alert until reaching the straightaway where the speed sign is. I suppose this could be caused by the speed sign being slightly blocked by the trees, but I was a little disappointed by not getting any alert until I had line of sight to the location of the source. (I muted the alert at 0:37 and I drive by the speed sign at 0:41.) I have K band sensitivity set to 60%. I feel like this could have ended badly had it been a cop there instead of a speed sign. Ramp wasn't aggressive enough that I would have slowed down until quite close to the source.

2) Starts at 0:42 in the video. Local police running Ka 35.5, passing me on the road I'm turning on to. He was clearly running his rear antenna. However, I didn't get an alert until he was right in front of me; I thought I would have picked up a reflection before then. What do you think?

3) Starts at 1:19 in the video. Another K band speed sign, being picked up around a bend. Sign appears at 1:51. I thought the ramp was a little strange as I approached the sign, but this might have been caused by the truck in the right lane blocking the signal. Would you consider this range normal, given the terrain and my 60% sensitivity setting? I'm loathe to increase the sensitivity because I'm already getting very frequent K band falses (I had about 15-20 each way in 80 miles of highway driving, with K filter and K block on).

Let me know what you all think about whether there is any legitimate concern, or (more likely) I'm being paranoid and this performance is normal.

(I apologize for the poor video quality. I'm using iMovie to process the files and for some reason it's lowering the resolution. I haven't figured out how to fix it yet.)

Looks good to me.
The quality in iMovie is almost the last screen

Your unit seems a bit on the cold side BUT keep in mind that houses, terrain can greatly impact detection ranges for ANY detector .

Watch this video that i made in an urban setting with a radio shack detector from 1995 and the R7 to show you how much houses can impact detection ranges.

On the K band, again, without knowing your specific settings on your detector it is hard to tell is it highway mode? K BLOCK? TSF ? Qll these things affect range.

Did your detector come with firmware 120.120?

Just curious.

Thanks for the reply! Did you think there was anything concerning about the footage?
Not really. Give it some time and see how it does out on the highway. You should get some mind blowing alerts with a R7! Terrain can cause some crazy stuff!

Those clips were in Advanced mode with 60% K sensitivity. K block is on, TSF is off.

The detector came with firmware 121 and has serial number 7xxx. I updated it to 124 when I got it and performed a factory reset.

Thanks for the comment.

I was actually out on the highway today, and I captured two different encounters with C/O Ka 34.7. Neither was encouraging. In both cases, it was unclear to me whether the officer was running front or rear, but the ramp I saw would be confusing in either case.

1) Coming over a hill, R7 alerts less than two seconds before line of sight with the officer, who's sitting in the median at 0:28. This does not jive with all the videos of fantastic over-hill R3 and R7 detections I've seen on this site and on Youtube. I realize traffic was heavy, but the performance still seems mediocre. You might say that maybe he was running front antenna only, but the signal became even less urgent when I had passed him.

2) Starts at 1:13 in the video. First alert at 1:17, source appears at 1:38 on the opposite side of the highway. Again disappointingly short range (about 0.3 miles), again confusing ramp-up. Rear detection was actually longer than front detection.

I'm not feeling like this detector is delivering the stellar performance I expect from an R7. I'm thinking of returning it for another. Anyone have any thoughts on these encounters?

I mean there is a lot of concrete there to block signals.

But if it makes you feel better trade it in.

I did get a good deal on the detector, and I’m reluctant to pay full price for a replacement, which is why I haven’t traded it in already. However, I definitely would rather pay the extra money than have a faulty or cold detector. That’s why I’ve come to the forum for help to see what you veteran users have to say about it.

Regarding the concrete, I do understand that the traffic conditions and terrain are not going to allow me to get multiple mile detections. However, concrete doesn’t serve as a radar sponge the way that foliage does, so I would still expect signals to be reflected off the barriers such that, in that first detection for instance, I would be able to get a blip more than a second or two before the kill zone. Of course, I am happy to hear your feedback and the feedback of anyone else regarding whether everything here is explainable; that’s the reason I posted this footage here.

Ok honestly I would take it back and pick up another one if you are still in that time frame. Unit appears a bit on the cold side and it will only get worse. You will wonder and regret it, trust me. I had similar experience with my R1. They sent me a different one back once I sent it in for warranty repairs. I haven’t had much seat time with it since we got it back, but my wife tells me it works about the same as the Pro M we have based on time to react and detections. She said “it beeps, I slow down, then I see them, just like the little one”. It was more like you see them, start slowing down, then it beeps before the warranty work.

If you want to wait and try some other things, here is what I would do. Reflash to 124, reset, and reconfigure. Then go get some more seat time with it. I felt like my R7 performed better after the 124 update. Mine in the 4xxx serial # range.

Oh and meant to say, Thanks for sharing!

Yeah, I mean you won't known for sure until you try a different one.

I did and I feel like the replacement is hotter than my last one.

So do it for your peace of mind

Thanks for all the advice. I am going to order another unit and hopefully I will get a chance to try some objective testing of one against the other before the return window for the first one expires. If I’m not able to do that, I will just send back the first one and see how I feel about the second one’s performance relative to the first after running it for awhile. It seems unlikely I’d get two cold detectors in a row.

Try Best buy, you have a couple of week if it is better keep it if not return it and keep the cheaper one.

Tonight was the first night I was able to get my hands on the second R7 copy (I've been away for a couple weeks). I took both detectors out and tested them against a 24.13 K-band speed sign, and I could not discern any difference in performance. I'm not sure whether things were terrain-limited, but I thought the detections were pretty good (0.45 miles in city mode). What I'd like to do is test with a Ka band gun, but I don't have access to one. I may just send back the older one (the one used in all the videos in this thread) and hope for the best, unless you all have any other suggestions. Again, it seems the odds are pretty low that I got two cold ones.

At least you can rest assured you tried.

All right everyone, I sent back the old unit and I'm currently in the process of trying out the new one. After a couple of highway stretches and several Ka band detections, I can say that I'm more encouraged by this unit's performance than by the last one. It's probably confirmation bias but I think going through this was worth it for the peace of mind.

I posted one of the detections just now in this subforum. Hopefully there will be many more to come. I'm doing 160 miles tomorrow and 600 miles this weekend. Thanks to everyone for the help.
