R7 does not un-mute

Several times I have muted my R7 and minutes after the original has passes the R7 picks up a new and different alert but it is still muted. Today I muted for what appeared to be a BSM signal which when past, several miles later I saw a full blown state trooper and thought his radar gun must have been off. However when I glanced up at the display I had all bars thus he was active. I do use the remote mute cord. I have seen similar events several time today on my drive and had not noticed it in the past if it did occur. Is this a Uniden problem or this users problem. Any ideas appreciated since Friday I have a four day trip and a almost 4000 miles planned.

That’s correct.
Look in the testing section and @Vortex latest video.

Thanks Heywood. I am taking from your response it is a know R7 issue.

:unsure: Heywood, do you have a link to this test? I'm not seeing it yet.

Just so I’m understanding this correctly,

For example, if you get 24.125 from a Mazda BSM, mute it, then miles/minutes after that alert has disappeared, you get a visual alert from a state trooper, but no audible alert?

Or

You and the Mazda are in the same vicinity for miles, you have the false BSM alert muted the entire time, you spot a state trooper and are only seeing a maxed out visual alert for the trooper but there’s no audible alert?

Either way, once you mute a signal, 10 seconds after that signal ends, and then a new signal is detected, it shouldn’t be muted. If a new band is detected during a muted signal (Ka during a muted K alert for example), the detector should alert. If you have a K BSM alert muted and a K signal from a LEO is detected at the same time, that should alert too, but IIRC, there needs to be a certain +/- MHz difference between both signals for the detector to unmute to the 2nd signal.

I’m not saying there isn’t an issue, just trying to get on the same page.

If you hit the mute button to mute a K-band alert, if your R7 receives another K-band alert in less than about 10 seconds from when the original muted signal disappears from your display, it will maintain the muting for the second alert. Since Uniden, like many other manufacturers, mutes the entirety of the K-band spectrum when you mute an alert (unlike a lockout, which is +/- 35 MHz), any K-band signal received within < about 10 seconds from when the original muted alert disappears from the display will still be muted. At least I believe that's the way it would work based on some past testing. But it shouldn't be for minutes or miles beyond when the muted signal disappears. I believe Uniden implemented things like this to avoid users to have to keep hitting the mute button for a BSM from a car where the detector briefly drops the signal because of traffic, for example.

Let's also make sure we aren't confusing this with the issue of "traveling" (for want of a better term) lockouts, where if the R series receives a second K-band signal within it's lockout radius and frequency range (+/- 35MHz), the lockout will travel with the second signal (this is the testing I believe @Heywood is referencing). I believe Uniden implemented lockouts in that manner because because people complained about having to use more than one lockout on a given stationary false due to the detector's range. I'm not a fan and would rather have a fixed lockout radius and use more lockouts if necessary, but people also complained about only having 200 lockouts with the R3. So I believe this was Uniden's compromise. But you could have a situation where if you encountered a BSM in the same +/- 35MHz frequency range at a place where you have a lockout, the R7 and R3 could "carry" a lockout as long as that BSM was still being received, and the BSM would be "locked out" so to speak as you traveled down the road as long as the R7 or R3 didn't drop the signal.

Several miles, as stated above, is a lot more than 10 seconds of time passing. I am wondering what the issue is that he experienced? Based on the responses the unit should have alerted, but it did not.

Are we sure that Uniden does that? Some or all of the Radensos do something like that.

Ok.
The lockout range is +/- .035 MHz of the manual lockout. So depending where you lock out the original frequency.

With Uniden, if the 2nd signal fall within that .035 window of the locked out frequency, it wouldn’t audibly alert to it. It would visually, as the OP noted, but audibly, it would be silent.... along with the lockout.

As for miles? The only circumstance I could see that is if you muted a BSM, stayed in that BSM widow traveling and then encountered a 2nd hit in that .035 window. I’ve never tested that as it’s pretty hard to reproduce, but could possibly happen.

This is the R3’s lockout range bench test I did to see the range. I did the same to the DFR9. I haven’t done the R7, but could. I don’t expect it to be different.




The Radenso’s actually use distance. It may lockout all the K band in that lockout window, but it only lasts for 1000 to 1300 feet.

Minor correction. It's a total frequency span of 70 MHz per lockout.
(35 below and 35 above)
(I know that you knew that at some point and maybe misspoke, but for those that don't know.)

Thanks for the link. I remember the thread. I thought you were referring to something newer. :)

Your right. Total of 70 MHz. Anywhere .035 below or .035 above the lockout.

Again, let's not confuse lockouts with just muting a signal. It's different.

After all this, watch the OP come back and say the trooper was transmitting Ka

Back to the drawing board....!

Not likely but...,

Is there a reason the block is so large @ 70mhz? The 9500ix used 30mhz blocks... the digital detectors are supposed to be more accurate with determining frequency, so you'd think they'd need less of a block.

I don't have an official answer. I'd guess that the "traveling" lockout and the 70 MHz span are both efforts to minimize resource use.

A well placed 70 MHz lockout could eliminate a lot of nearby sources with one location.
But of course a lockout at a common frequency of 24.138 would cover both 24.125 and 24.150 center frequencies easily. If the LEOs have tuned K guns in that zone, they will be locked out too. :(

I am the original poster. visual and audible Alert received muted. alert went away whatever it was then drove several miles and new alerts did not come in audible only visual. Different frequency and the old alert was not present and had not been present for several miles period. Mute set on first initial alert not lockout set. even if lockout had been set the detector should not have gone in silent mode after several miles. I would guess 7 or 8 miles.

@hotdog, do you remember the frequencies? (I realize that is asking a lot because you wouldn't have thought you needed to remember the initial frequency because there wasn't an issue yet.) :)

@hotdog - since it appears from your original post that this has happened more than once to you, I would suggest a reflash of the fw, and then a factory reset of your settings. If it happens after that, I would think about sending it in to Uniden for a warranty repair/replacement.
