Re: If this is a bug it's a "deadly" one

Excellent point! I don't think it's a good thing to leave any RD on the windshield and let it bake in a hot car. IME, doing so caused K band detection my Magnum to drop out without warning, and caused 33.8 detection to disappear on my 3.894 V1. OTOH my Redlines seemed to be fine in the heat, as well as my R1. But why chance it?

As far as cell phone interference I have not seen that so far with the R1. At our Midwest Test Event there were 3 cell phones on at the same in my car, and it had no impact on detection time. The only thing that has interfered with it so far has been my Baofeng UV-5R radio and that is a polluting machine lol. I don't use bluetooth and my cell is about 2-3 feet away from my R1 so maybe that made interference less likely.

I can attest to the Redline and V1 baking in the sun with no adverse effects. However, my Bel V965 and Escort 8500 used to give error messages, stop working, random reboots ,etc only in hot weather if left on the dash.

Take care of your detector and it will take care of YOU!

Heat can negatively affect the performance of these Uniden detectors, according to [MENTION=3989]BestRadarDetectors[/MENTION] (I think he has posted about this here in the recent past). I would strongly recommend NOT letting them bake in a hot car, especially in the hottest part of summer. And if you do happen to bake it, then get some airflow over it for a while to cool it down before you expect it to work properly.

The Unidens may in fact be running "hotter" than any other detector on the market. Some here speculate that Uniden have designed the detector so that the antenna acts as a heatsink. So if that's true and you let your detector bake, then it's probably getting so hot that it's not working properly until it cools down to within normal operating temps. BRD has previously advised us to direct some airflow towards our units to avoid them overheating, so maybe consider doing that.

My Nexus 5 also causes X band falses on my R3, but it's usually only when I'm out in the sticks. I think the Rs might be extra sensitive to spurious nearby signals and hence susceptible to cell phone interference more than other detectors.

So heat and interference are two things we need to be mindful of.
I wonder if the Uniden's are "Self Calibrating" while in a "Baked State" on Power up, and as the cabin cools down, they are way off on Frequency (until rebooted at normal cabin temps).
It will be interesting to see how the Uniden's do when it's 10 below zero out.
I always setup my RD so they are NEVER in direct sun (parked or while driving) for numerous reasons.

It would be nice to know if [MENTION=5588]Mikelets456[/MENTION] could have had a baked RD in this case.

That seems like a very plausible explanation to me. Uniden might be able to write something into later firmware updates that recalibrates a set time after paying up to avoid that issue. (If it's confirmed, of course!)

f.
This is concerning. I never leave my detector in the windshield when parked, but it needs to be in the windshield while driving and it gets very hot. So far it has not impacted the performance, but it is very hot to the touch when removing it on a hot day. Most modern noncommercial vehicles do not really have a way to direct cool air to the R1/3. I will start checking temperature via infrared thermometer on hot days and post. I love my R3 and am very happy with it, but if I need to add a fan next to it to use it on hot days, my feelings will change. Maybe the R series needs to use light covered cases or fans.

What about the heartbeat? Does it freeze during this condition?

Installing and running it at the top of the W/S it doesnt get direct sunlight does it, most are covered by the headliner for some shade

A little window tint never hurt either

Anyone noticed everyone who reports issues like this seems to be running X band?

Maybe, but when using a temperature compensated oscillator I'm not certain how much impact temperature really has on performance.

I'm pretty sure if you're using your detector on an extremely hot sunny day for hours & your air is running your detector will be fine mounted on your windshield without the need to add a fan.

Got to admit you might be on to something. The only time I've ever felt like my R3 when to sleep was right after a strong KA band alert was immediately silenced by a strong X band alert on the HWY. But I can't say with 100% certainty it went to sleep. But changing the mode woke it up. Police was right in front of me with no alert till I changed the mode. And I was driving through an area that usually run C/O. Was this a coincidence? Could of been using I/O. Just wanted to share this experience just in case.

It can actually makes things much hotter for your detector

1.28 here and I haven't seen any ghosting like that but I have only had mine for a couple of days

Tint - explain

I believe I'd had my R3 go "on vacation" at least 2-3 times THAT I know about - this is the issue, I don't know what I don't know

One time I was behind an Escalade so I believe the R3 was so busy handling the BSM that it also filtered out the legit source while my Redline altered later than usually but correctly highlighted 2 K sources

No, the bolded sentence shouldn't be the case at all. It's supposed to be designed to work in an automotive environment and it should be designed to handle the temperatures. If Uniden can't do this, they need to go back to the drawing board (or hire engineers who are competent designing for automotive environments).

It was shipped with 1.28. I believe that you will get 1.29 software next week
