Is 34kbps objectively terrible performance?
Yes. Yes it is.
Am I incredibly fucking amped that my own layer 1 and 2 can hit that speed over my SDRs? ALSO YES :hztools:

:boostRequest: Due to life decisions that I am comfortable with , I use my SDRs over the network with my own goofball protocol.
Existing apt installable programs don't support it, so I figured it was high time to do what any normal person would do -- convincingly implement librtlsdr.so off my rust sdr codebase (sparky) and make it work without any other changes. Obviously.

A few nights ago I bought some restaurant pagers off the internet and blind reverse engineered them for fun! It wasn't quite the adventure I wanted but still an excellent exercise never the less

:boostRequest: I wrote a few words about my bootleg phased array simulator and some renders over at https://k3xec.com/simulating-phased-arrays/ published this morning. Enjoy the 90s screensaver vibes! Hopefully more to come soon!

I wrote a janky little renderer for my #hztools simulator's point clouds to check my beamforming code in 3D
First GIF: The camera is rotating around the 1x4 line of antennas beamforming at the horizon
Second GIF: The camera is fixed, and the beamformming is sweeping from 0 to 360
Enjoy! This was a *ton* of fun to write. #rf

I finally got around to thinking about 3-D beamforming, ported a branch of my beamformer and wrote up a quick "simulator" to test it -- it's a lot harder to view this than the 2-D images I posted a while back, but I exported it as a point-cloud and opened it with Blender (nice!).
This is the 3-D render of a 1-D line of antennas spaced a quarter wavelength apart on the X axis -- I expected to see a torus (and did!)

I've been goofing off using #hztools and asterisk to tune into FM over the VoIP network in the house, and @mikey pointed me to AudioSocket, a very handy (but underdocumented) protocol that Asterisk can use to patch a call into a TCP connection.
There's not a *ton* on the Asterisk docs, so here's my small contribution as I implemented support for it https://hz.tools/audio_socket/
Also, it's pretty rad to have a phone get answered and hear local FM traffic 📻
