Hello all,

I've just started using my new Uniden R3, and was wondering how to set the K band (Wide vs Narrow). I previously had an Escort SmartRadar that falsed all the time on K band. I can't even remember the last time I saw a real K signal, but don't want to turn the band off completely. Just trying to eliminate as many falses as I can. Hoping if Narrow will work in my area it will at least stop some of the Acura/Honda falses. And of course I'm going to reduce the sensitivity to 70% (for now) as has been suggested multiple times here on the forum.

Thanks in advance for any insight you can provide!

-Nick

K band is for sure alive and well here in ky. I’ve seen as low as 24.060 and as high as 24.200 being used in the real world. You could reduce sensitivity quite a bit but I would definitely run k wide. Be sure to turn k filter on as well. The r3 will filter a lot better than the smart radar.

Thanks for the quick reply! I'll leave it on Wide I suppose. At least the falses with the Uniden aren't full blast like they were with the Escort. I finally just turned K band off on that detector because it had me crapping my pants every quarter-mile. :-/

I also had a weird issue this morning on Ka band. I assume I was picking up another detector on my commute this morning, as it kept up all around the bypass. Was getting a weak signal off and on in the 33.7-ish band. But every time it came back up, it was lower by one-thousandth on the signal readout. Ever hear of anything like that?

This sounds like a false from a leaky detector. Cheap detectors like Cobras tend to emit strong signals from their LOs in the 11.2 GHz range, and the third harmonic of this signal is picked up by radar detectors as a 33.7xx GHz Ka alert.

Running Ka filter on can help with these falses, and segmenting Ka band may help as well.

Awesome, thanks for the insight and tips. If I continue to see this, I'll give the filtering a try.

Turn TSF ON; it helps!

And I would NOT run Ka wide. I would segment to probably: 2,5,6 and 8. Others off

I'm not sure if it was the reduction in K sensitivity (to 70%) or turning on TSF, but the detector has been much quieter over the weekend. Thank you for the suggestion!

As for segmenting Ka, I'm probably going to hold off for a while. That's the majority of what I see here in central KY (other than laser), and I'm not terribly familiar with what bands are commonly used in these parts as of yet. But again, I do appreciate the help and suggestions!

Thanks,
Nick

Those K settings, along with K filter ON should be ok to detect quick instant on and give you plenty of warning.

Those settings kick @ss against K band IO! I got popped with IO 24.150 today on my way back from lunch going through a school zone. While I never speed through there,I was picking him up from over a mile away as he was popping cars ahead of me!
