Good evening, ladies and gentlemen.

Today I've been reviewing the recent daily footage from my dash cam and I came across something, I had completely forgotten. I remember that my R1 went off on X band all of a sudden on that day and I didn't even have time to perceive what happened. I thought it must have been a false alert and kept driving on my way carelessly. But on my footage I saw that it wasn't like I thought and the alert was fully legitimate. That was just my daily commute and I wasn't paying attention on my surroundings. I was driving with my R1 in City Mode, which is less sensitive mode of course, but I didn't expect this happen. They often shoot here on X-band using one of their fully automated combined/linked RD+Digital Cameras that detect and take pictures in a matter of seconds. AFAIK the maximum range of this equipment is 0.6 km=0.38 miles, albeit it wasn't more than a 100-200 m here. Thank God I wasn't speeding at that time, otherwise a fat ticket would have awaited me in the next couple of days as my "reward". Nasty trap was that anyway by them hiding there and shooting at angle. It was IO and R1 was in city mode but why it was so insensitive? They must have shot someone ahead and R1 didn't sniff anything at all. A little bit disappointing. No reaction time at all in the kill zone. Maybe from now on I should be switching to the Highway Mode there.



And two selected "bonus" materials from my collection, because I wouldn't want to start whole other threats:
New installed MRCD cam was detected in my neighborhood

This manner of "conquering" the right of way, while making phone calls on top of it, is driving me crazy!

Yeah, sometimes it is good to be oblivious, like I was. You stomach it better. :)
Don't speed too much! One never knows what's lurking behind the next corner.

@skd I/O is a killer when the cop is being selective on pulling the trigger. No detector would have done any better. The LEO found himself a very good ambush location.
I absolutely agree. No matter which band - X, K or Ka - IO is always a killer. Even more so that the officer just pulls the trigger and a machine is doing the rest in just a couple of seconds - detection and taking pictures of speed violation. I just thought... would the situation be better with the sniffing of the traffic ahead if I was driving on Highway mode? I would be grateful to someone from Ohio or from other state with X band experience to share thoughts. I've got R1 from a comparatively short period of time and don't know how less sensitive it is on X band in city. But... I will always drive on that part of the road "Highway" from now on. We'll see what will be happening next.

I found the so-called "sensitivity" settings are nothing more than "high squelch" settings that "full-alert" when the threshold is exceeded. If X band is in use, use Highway mode.

X band is not in use here, but I listen to it so I can lockout doors and test range. I dial it back for my wife's sake, but if it were easier to turn it off, and save that in the Advanced setting, I would prefer that option.

Thank you
Traps like that would get broken and stolen in us cities

Yikes... :owned:
Is the speed limit only 50 km/h on the bypass there??
Thankfully not entirely. There are always segments of the road like this where more people could be passing nearby and incidents could happen. In my case I was passing a segment between two gas-stations in a some 200 m distance and there is a LP speed cam on the first gas-station currently empty. I am more concerned why my R1 didn't give out a single weak chirp and I know that these guys were shooting all the traffic ahead. The PSL after the second one is 80 km/h or 50 mp/h.

Disclaimer:
No one keeps it after the second one. LOL

Hahah, that makes more sense. I think the reason you didn’t get a chirp is because placing a detector in city mode usually mutes X band alerts below a certain threshold. So if the R1 picked up a weak signal, it wouldn’t have alerted because of city mode. I would leave the detector in highway mode if you face X band threats like this.

Yeah, we have any kind of threats here - X, K, Ka, L... Got it now but everyone learns through mistakes. I only now have to recognize a fault that I didn't order an R3 with its GPS QR function. R7 isn't cheap in US but here it would get even much more expensively. Because no-one imports Unidens here, beeing and American based and oriented RD, everyone has to do it on its own. I will be switching to highway as soon as get on such kind of bypass roads and will see later on how things would change hopefully. And one more thing I may have to change. Now I have set Ka Priority and maybe for me would be better Signal Priority here. Ka is much more rare than in US.

@skd when I had an R3, I went to Ohio on a trip. I ran it on highway mode because I was aware of X band being used there. So, to answer your question about your R1 being sensitive enough to pick up X band, yes it is. I picked up a LEO over a hill running I/O about a half mile out. The difference in your case, he didn't seem to be clocking anyone ahead of you near enough to be picked up on city mode. Hope that helps.

@RadarScout, it helps. Thank you. I've realized my underestimation of this situation, I would admit as a huge mistake on my part, and I do suspect too that they weren't targeting anyone ahead until I was too close ready to "die" if I was over PSL. Just... that was so freaking out close that I didn't even realize what happen at real time, as you can see from my footage. And didn't expect it exactly for X band, whereas I would expected it for K band with FW 1.46, I've been using since the very beginning. From what I read on this forum, I was left with impression that R's are quite sensitive even in city mode and that's what I have been testing since a month. Been searching through the forum but didn't find it how much the X band sensitivity is lowering during "city" mode. I know for K that it was 20% or so there and 30% at minimal on advanced. Having in mind that R1/3 aren't the best possible sensitive rd's on x band (compared to most escorts or V1 or even some Cobras), I believe X band is going too low on threshold in City to give out an early legit alarm from distant short IO signals. But even so I know that R1 is so much sensitive even in City and I had recent good CO alerts in town... but this case was so unlike the others. Even in City mode, even with all filters On, R1 is giving always false alerts from a close distance to door cells of gas stations, shops and etc. In conclusion I will amplify the detection mode beginning with highway and testing advance mode at the end, and additionally will place Signal Priority, instead of Ka Priority, to eliminate the risk for X band to be left as last priority, and later in time I will share my results. Every time now passing by the first gas station I am getting a false K alert around 24.174GHz and this time I see on footage no alarm at all, what takes me to some suspicions. And I really don't remember what was happening then, it was so quickly, because I was watching the road ahead. Meanwhile I will be expecting with great interest the upcoming X band tests and will search through forum here to try to make up my best possible defense strategy. Because if I don't, next time may be fatal. Well, as many already noticed here, times of the good old CO are slowly dying. :confused:

The LEO found himself a very good ambush location.
Hell yes he did. Cars going in the opposite direction didn't even know he was there. Hence no headlight warning flash from oncoming traffic.

Was just going through the search engine of the forum and what I found, shocked me. Based on the calculations in this older but most useful thread it turns out that, while driving in City mode, R1 was operating with reduced sensitivity of 3.16% and nearly six times reduced range. Holy Cow! What I've been thinking? :doh: As soon as I get on my car I will immediately switch to Advanced mode with full X/Ka bands sensitivity and and say 40% at K. The latter must be reduced, otherwise it is almost unbearable. And Signal Priority is the next thing I'll choose. I believe these calculations could be referred to X band just like to the K band, right?
