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.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
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?
