  • I was surprised by that, too. When I went looking for a way to decode them with RTL-SDR, I assumed it wouldn’t be parsing the audio but a narrowband data stream. TIL also.

    Edit: It does kind of make sense with it being AFSK encoded in-band, though, or maybe I’m just so used to it being that way. I always thought the screeches were there to demand attention (and also be something that headend equipment can pick up and respond to). So it’s interesting they’re doing double duty as both an unmistakable audio cue to pay attention as well as containing the actual alert data.

    Plus there are NOAA stations all over the country rather than centralized like the time signal transmitters. It was probably cheaper to do it in band at that scale.










  • That’s what I’ve done for years. Makes managing things much easier, and I run multiple APs (all with the same SSID/PSK) and you can just roam to the best one. One upstairs, one downstairs, one in the weird dead zone in my office, and one on the back patio (it’s not hardwired and uses the mesh connection for uplink).

    These are all old Aruba APs running OpenWRT but that’s the plan for this Cudy Model. I may pick up a few more and just replace all of my trusty but very old Arubas.





  • The world is just as fucked up as it ever was. The only difference now is that every fucked-up thing that ever happens anywhere is getting pushed to your always-on doomscroll device in real time with people attaching their mostly ignorant opinions to it.

    This is where the “touch grass” advice comes into play. In broad terms, the real world is not nearly the hellhole social media portrays it to be.
