BSM falses over-driving NR DSP into Ka falses?

Hi fellas,

Been noticing for over a year now, but have been living with it, that my NR DSP seems to be over-driven when a strong BSM source is near by and giving me a Ka band false at ~34.85+-.
The false alert almost always lasts three alarm sounds and then goes away, then it may or may not repeat after a few seconds depending on traffic conditions.

Anyone else noticing this? I have k band OFF, and run a R7 on the windshield. I do have segments 2/4/5/6/8 ON due to stalker paranoia, and I was hoping to keep segment 6 ON.
I assume it's being over-driven because it's always a jeep, crv, or mazda near by (in front of me) when it happens, but I'm not 100% sure my theory is right. Most of the time the R7 doesn't false on K band at the same time, but I realize that these vehicles not always make the R7 false.

Thoughts?

Haven't seen this issue with my DSP.
Question: since you have K off, and therefore can't detect BSM's, can you be sure there's a correlation with your Ka falses?

It took me a while to believe that it was possibly a BSM over-driving the detector and it is a far fetch idea I'll admit.
The fact that these falses ALWAYS last 3 alarm cycles and then stop (and may or may not repeat after a bit), and when I look up I always see a typical BSM offender, made me think that it could be the case.
I'm not sure if having k band off only affects reporting k band or if it shuts off scanning for it. The same as ka segments, does it not report it, or does it not "see" it.
It's strange behavior, I can't pin it to specific locations, and it's hard for me to think it's a ka false in the ~34.85x.
But if no one else with k band off is having this happen to them, maybe it is ka falses from sources I don't know of.

What firmware version is on the NR DSP? Have you kept it updated?

It so happened that early today I was downtown and really got to see this Ka falsing in action.
My R7 was falsing to door openers or whatever with very strong k band signals, but no Ka, while the net radar kept detecting ka band in cycles of three alarm tones, then off, and after a few seconds another three alarm tones...

My escorts do it too. Didnt use the frequencumy display and seeing the ka freaked me out a couple times on the x70. I run spec on the max 2 and have gotten 33.8 falses and and 99%i have gotten those 34.85 falses too

Some of us have seen the Uniden R3 exhibit the exact same behavior on V1.48 and V1.50.

What causes it? Are the signals that similar?
Without the equipment to “see” the signal I can only speculate that it could be some area of energy produced in the modulation pattern, a harmonic, or it’s overdriving the detector.
