Honestly, there's a single municipality near me that has one Explorer with a Genesis I that transmits at 24.196. K Block is so good that I take the chance and just slow down while traveling through that town while running K Block ON. Now, I rarely travel through that town anyways, but K Block makes such a world of difference that I'd rather take that risk. YMMV
If a detector's solution to "filtering" is so bad it relegates you to driving PSL, that's unacceptable IMO. I'm glad @Vortex pointed out this was a "stupid hack" in his last video, and hope this means Uniden is actively working on another solution and just provided this as a stop-gap solution.

I can see why a detector would alert initially to these BSMs, as the initial alert looks like CW K band. However, averaged over a few seconds, the detector can clearly see the frequency modulation in the BSM signal, as the frequency "jumps around" during a false. For example. the last one I saw varied between 24.198 and 24.207 GHz. Given this, shouldn't it be possible to combine a short time mute on K band (eg 3 seconds before the detector audibly alerts) with the detector monitoring for changes in frequency during this time? The detector could even be made to focus the K band sweep on this range for a few hundred milliseconds after the initial alert to confirm it is a modulated signal and keep the alert silenced. This sort of focused sweep should be able to identify pulse or chirp modulated BSM signals as well.

Can anyone think of a reason this wouldn't work?

100%!!

I think whether it would work would be hardware dependent, both for keeping track over time as well as creating and implementing and executing on algorithms to analyze any variance and come to the conclusion that it's a single alert source and that the alert source can be safely ignored, differentiating it from any other alert source. Might be tricky.

I would think with a short "focused sweep", a FM modulated signal would be easily identified as a single source. Without a focused sweep, the apparent frequency shift would be dependent on the overlap between the radar gun sweep rate and the RD sweep rate, but still should be easily distinguished from a CW source in most cases.

Although if it were this easy I would hope it would've been done by now. There is probably something we're missing here.

One thing I noticed here in Calgary since switching to 1.50 (besides how wonderfully quiet it is) is that there is one of those signs that says "Your speed is" and it shows you what you are doing. East Bound Memorial right after the 10th street bridge. I no longer chirp at that. I did not think those fell in the same low end spectrum that would have been blocked.
I believe that sign is at 24.189, awful close to Notch filter (24.194 – 24.205GHz.) I'm on 1.37 and picked it up on Sunday still.

Ran here in FL with K-Block off but kept getting BSM's. Turned it on and much better for sure. I get a lot around 24.098 though...

Have you tried running it in advanced or even city!? I've picked up cops in city mode before and for sure on advanced @ 70% when in the sticks and no worries about BSM! :)
