Although it's being called a notch filter because it only affects a certain range, you do realize it doesn't block out all signals in that range, correct? And btw, I'm not saying don't be careful, but it seems like people are acting like no signal be be alerted to in that range.
I assume you're referring to how some people are still seeing alerts in the range. It appears to be a bug, not by design based on what I'm seeing. K-Block simply doesn't work at all if MRCD is enabled. There may be other feature combinations interacting too, but that one definitely seems to.

So with K-block on and MRCD on, you are getting punch-throughs from every Honda/Acura? @Dukes - are you seeing the same thing?

And I'm not actually talking about how some are still seeing alerts in the range. I'm mainly talking about how on my bench with K-block enabled and a K-band gun tuned into that range, it will still alert to the K-band signal, presumably because of its strength, or perhaps because it's not frequency modulated.

I haven't seen an alert come though with K-Block on and MRCD off, but I don't encounter all that many new Honda/Acura vehicles in my town. I did a similar test as you except with a K-Band Gunn Oscillator. Tuned it to 24.200. R7 will alert to it (as K-Band) with K-Block enabled if MRCD is also enabled, will not alert is MRCD is off.

Well, crap. As usual, I'm not sure I've tested with MRCD on and off. Looks like I need to do that.

Yeah, hard to test every combination of settings with this many options. I lucked into finding that combination pretty quickly. If you want to try to replicate, my settings for the test were as follows:

Highway
GPS Off
Voice Off
Ka Freq Voice On
X off
K on
Ka on
Laser on
K pop off
Ka pop off
K filter on
Ka filter off
TSF On
K wide
ka segmentation, 1,2,4,5,6,7,8 on
Ka Priority
All threat on

@Brainstorm69, I corrected my warning on that notch filter in one of these threads. Maybe I didn't do that in this one.

Can you describe how the notch filter DOES work for us?

OK, well I'm getting something even squirrelier than that. With K-block on and MRCD on, K-band comes through. With K-block on MRCD off, and K-band punches through randomly, although it mostly seems blocked.

At this point, I may need to go back and correct what I've said. I was not aware of this until now, and until we can get a better answer from Uniden, I can't explain it at this point.

Thanks for messing around with it further! Obviously my testing is fairly limited with the tools I've got. I should probably pick up a real radar gun at some point, but I've learned a hell of a lot about different RDs (and found several bugs over the last few years) with that oscillator since Professor Jim clued me in to them probably a decade ago on the old forum. Don't know whatever happened to that dude, but I sure miss him being around the forums.

I have edited my comment above in this thread. Need to go find the other places where what I previously said may a problem.

BTW, I did ask Uniden for more information on Friday, and just reiterated that request along with passing on this new info just a bit ago.

Very interesting findings. I drove a few hours today again with the R7 and even though I clearly passed many Acura and Honda with BSM, it didn't alert me. But I did notice a few punch through during my drives today, more than yesterday. I had 1 yesterday. Today I had 4. These were the frequency I saw: 24.194, 24.199, 24.200, 24.204. I have MRCD On | K Block On.

Edit: All these punch throughs were in the rear horn because it always showed the signal behind me. @Brainstorm69 in your testing, see if the rear lights up more than the front.

Do you think it has to do with overloading or the K band source is very close? I remember reading my toyota manual that the radar can only detect 10-15 ft for BSM.

Don't know. Hopefully Uniden will shed some light on it.

As someone who's seen two new K-band units in the 24.200 range in the last 8 months; I implore all of you to make sure you understand what the notch filter does before using it.
Using it in the wrong scenario is like turning off your detector unless there's still some sort of alert. It will be interesting to see how it's implemented.

AltecBX, That was a well thought out post. :)
Agree with you 100% no way I would use this setting. I would rather have a false alert then miss a legitimate alert. A good detector will pick up false alerts that is just how it is. I will be disabling gps auto lockouts also until I'm sure they will pick up another signal in the same frequency range and alert to it.

That reminds me; what's the frequency spread on an R7 lockout?

I've been getting 24.200 quick blip then goes away fast on a R3.

You mean the K Block? 24.199Ghz -/+ 5
No. On a lockout, there's a range +/- that gets saved. A 24.150 would be saved as 24.146-24.154 on mine.

What's the spread of a lockout on an R7?

Gotcha. To be honest. I have never seen that information posted.

The lockout spread on my R3 running 1,48 was +/- 35 from the center of the manually locked out frequency. The DRR9 was the same.
I haven’t tested the R7, but past history of 2 other units would lead me to believe it would be close.
They’ve been pretty good at that. Not exactly as stated in the manual, but FW updates sometimes do change it one way or another.

Cool thank you kind sir.
