OK, so a lot of you who might have been (mercifully) reading my posts, know that I have my struggles with the MAX 360, but stay true, 'cause at the end they 1) fixed the firmware (really?) and 2) it works for me.

Either way, I keep the Uniden R3 low on the center of the windshield and MAX360 high above my head on the visor, and they seem to place nice with each other (have not noticed any funky 'interference-like' behavior) and because it gives me a chance to try both out and go head-to-head.

I also am not sure yet that I trust the MAX 360 completely, so besides having fun, I also serve that purpose.

So today, my Uniden starts alerting to 34.7 on the freeway. Maybe like 34.702 or something. This is normal. On the open highway, the Uniden usually alerts first, esp. with 34.7. This time it was different, though. The Uniden kept ramping up until it was going crazy, five bars, and I even had a visual on "Smokey" pointed my direction with somebody pulled over on the other side of the freeway, and *the MAX 360 was absolutely dead silent the whole time*. :-O

I kept looking at it to see if it would do anything, and it just read "Highway" and you could see the MPH changing.

So I powered down the MAX 360 and back up again, and had the good fortune of running into another "Smokey" about two miles down the road, this time running 34.688. They both alerted this time, no issues, but I'm honest when I say, this one really has me scratching my head...and even a little worried.

TLDR: I run both the Uniden R3 and MAX360 together, and never had any apparent interference issues before. They both alert to the same stuff, and seem to play nice. During an encounter with 34.7, the Uniden alerted to full five bars, and the MAX360 didn't alert at all. When I powered the MAX360 down and back up again, I had another encounter that showed the MAX360 was "back to normal" and alerted as I am accustomed.

QUESTIONS:
-Is this a typical case of interference?
-Is the MAX 360 known for going temporarily deaf on Ka band?
-Has anyone else had this happen to them before?

This is kind of a bummer, because I was really beginning to trust the MAX 360, and now this. :-D

Thanks, gentlemen, appreciate your kindness, and going easy on the newbie. ;-)

I have never run 2 detectors together, so I can't speak for that - you tell Escort you are doing that and it will be what they blame.

I had a sleepy M360 that would quit alerting to radar but still show EL PSL and MPH. As soon as I created a thread on the Escort forums over it they had me send it in. From the paperwork that came back with it - it looks like they force loaded the firmware. Don't know what that did but it seems to be working fine now (knock on wood). I did try to update the FW on a Mac when I first bought it and it totally hosed the detector. Re-updated on Windows and I thought it was working, but I found it had the sleepy thing every week or so. I think the Mac update screwed it more than I thought and it needed whatever they did to load it.

Yes that is very much a typical sign of interference. The R3 put the M360 to sleep. a power cycle woke it up. That is the very reason we say to be careful about running two detectors at the same time, they wont always interfere but when they do it can cause late or completely missed alerts. here is a video of an R3 that put a Beltronics Magnum to sleep. same symptom.

You cannot run two detectors like that. And now you learn what can happen.

Thank you @TRS and @thebravo, both very helpful posts...I feel like I learned a lot.

So, I knew about the interference thing, but they were "playing nice", so I guess you just don't know. Again, appreciate this additional information. It's still worth it to me to run them together, because everything I observe from their behavior (when not interfering) matches with what I see here in the countermeasure testing, and I learn a lot in practice how good they are and whether they meet my needs, caveats applied*, thanks!

TRS, interesting information. I'll try to read more up about that and also the flashing program. Maybe it would be good to go back and reflash my MAX 360 with the newest software? Kind of a "refresh reflash"? Might be a good thing, given your experience?

Thanks to all the helpful posters, really really appreciate your efforts and information! Have a good weekend!

Playing nice is incredibly difficult to ascertain given the variety of conditions that you face on the road. Relying on playing nice experience when you have personal and many others with direct experience of interference putting another to sleep is foolish and asking for trouble.

Of course, it’s your choice, but we highly discourage running those two together. It’s unreliable and reliable is the name of the game in detector countermeasures.

Learning is what it's all about, and it's cool that you got to see fully destructive interference, many times it's only partial so one or both detector might give you a shorter alert than it would have otherwise, as you saw it's random in it's occurrence so it's really hard to know if the results you are getting are consistent.

Hey @thebravo, thanks very much and "yes", I think there's a tendency here is to think that anyone running two detectors together must be an idiot, but like you said, it's a matter of learning, and in my case I never said (did I?) that I rely on my detector for saves.
That is, I'm running both now because I don't 100% trust the MAX360, and wanted to make sure it was working properly, but I ask the questions because I "know I don't know" and appreciate the advice and the great community here. :)

Especially appreciate the kindness and understanding, because as I said, I'm new, but learning. Still learning... ;-)

Sorry but this does not make sense at all. You said above," I don't 100% trust the MAX360, and wanted to make sure it was working properly". So you add a second detector that will in fact 100% make sure it DOES NOT work properly.

Hi 9C1, what has been your experience with radar detector interference? What did you notice when you ran your Uniden R3 and MAX 360 together?

I know that I've run them both separate and become familiar with their characteristics, so that when I run them together, I know whether the behavior is different or not.

What have been the specific differences you noticed when running your two detectors together? Did it change response time? Did you notice the characteristic above? Did you do any testing to verify the effect on range and / or sensitivity and document it?

I appreciate your comments, but so far I think you just like to jump in, drop a one liner, and expect us all to stand back in awe. I'm not awed. I'm waiting for you to say something useful.

Don’t run 2 RD’s together in the cabin.

I have run 2, but only because I have a remote(Stir-O), and ones on the inside. But even then, I’m hesitating.

As for 34.7. That isn’t the Max360’s strong suit. I’ve ran it on old and new FW.

33.8, that’s a different story. That gives my M3’s a run for its money. 34.7, not even close.

Be sure to make sure your settings are correct, or if want advice, let us know what you have on/off., and don’t run 2 together inside the cabin.

I believe the Max360 periodically re-calibrates the noise floor while running. There is a video somewhere of the Max360 going to sleep on K band when powered up near a K band gun. It's certainly possible the Max360 adjusted it's noise floor while it was receiving interference from the R3, causing it to go to ignore the 34.7 signal. It would've been interesting to test in that case against a 35.5 or 33.8 source to see whether all of Ka band was affected.

If you don't like what I said maybe check with Vortex or some of the other true experts here and see what they say. I am no expert.



As an update on this I found this link from the Vortex Radar web site.

How to Conduct Long Range Radar Detector Testing - Vortex Radar


Vortex had this to say.

"Now the thing is, while radar detector testing is tremendously useful, it’s also very very easy to make mistakes in a way that would totally invalidate your results, produce inaccurate results, and would completely mislead anyone reading the results. In fact some mistakes are so common (running two radar detectors next to each other at the same time is the biggest one. Never do this!!) that almost everyone makes the same mistakes when first starting out so I’d like to cover both the do’s and don’ts of how to conduct a radar detector test properly."

"
Before we get into this, let’s start with the biggest thing:

–> DON’T RUN MULTIPLE DETECTORS AT THE SAME TIME!!!! <–
This right here is the single biggest mistake people make. It may seem counter-intuitive because if you want to compare detectors, why not just put both of them on your windshield next to each other and see which one alerts first? Seems like the easiest way to do it, right? Well here’s the deal…

Radar detectors aren’t just detectors. They also inadvertently emit radar signals back out which is why they can be picked up by radar detector detectors. These emissions will cause problems for other nearby radar detectors (cheap Cobras are especially notorious for this, causing Ka falses on nearby detectors in other vehicles) and when you run multiple detectors at the same time, these emissions will cause problems including delayed alerts, missed alerts altogether, and more false alerts. Even detectors like the Redline which are otherwise stealth to RDD’s, when placed in close proximity to other RD’s, even they can cause problems with other nearby RD’s.

Escort has a good explanation of it here, along with a very blunt, but accurate statement about it:"


Here is the link Vortex was referring to from Escort.

DO NOT test radar detectors side-by-side, explained - Escort Radar Forum


Here is a link from here at the RDF showing one detector putting another asleep and the related discussion.

www.rdforum.org: Interference; R3 puts Magnum into a coma!



Once again I am no expert but based on the information given it seems like running two detectors is not a good thing to do and will produce invalid results.
