I'm getting back into my software-defined radio hobby — here I'm tracking planes with an RTL-SDR and Raspberry Pi
https://reillyspitzfaden.com/notes/2025/05/tracking-planes-with-a-raspberry-pi/
In my Obsidian-style notes section on my digital garden, I also started some notes on my RTL-SDR software-defined radio hobby:
https://reillyspitzfaden.com/digital-garden/notebook/radio/rtl-sdr/
I first started playing with this in 2020, and every time I come back I have to re-learn a bunch of stuff. I previously stored all my info in a bookmarks folder in Firefox, and having nice notes on it is helping.
The wikilinks plugin (https://github.com/photogabble/eleventy-plugin-interlinker) I mentioned above is helping a lot with the Obsidian -> website transition.
@Jochen_Jansen gibt ne Menge Zeugs in #ISM-Bändern:
27MHz, 40MHz, 150MHz, 433MHz, ... 2,4 GHz, ...
Viel Spaß beim suchen, ohne #Datenblatt des Tachos und nen #RTLSDR oder gar #HackRF wirste nix finden!

I got tired of going outside and looking at the thermometer, so I got a digital weather station off Temu.
But then I got too lazy to walk to the refrigerator to read the base station’s display, so I hacked together a way to connect it to the Internet. Okay, so that’s not the main reason. I did it because I wanted a fancy APRS-enabled weather station without the price tag, so in the spirit of ham radio and hacking, I set out to build my own.
Then I hooked it up to Mastodon as @weather because… okay, I don’t have a good reason for that.
I put my weather station on Mastodon. Why? …I don’t know. But you can follow it at @weather if you want to know how the weather is right outside my door.
How does it work? This Temu weather station is connected to the internet through an SDR dongle, a PowerShell script to make toots and call other scripts, and my app (aprs-weather-submit) to connect it to the global APRS-IS network. I’ll blog about it later.

Here comes Fordie. Tyre pressure monitoring says at least one of the tyres is okay. And: Fordie is on the move so we possibly won't be seeing him again.
Good luck to your other 3 tyre sensors and watch out on the road!
Btw the cmd to get only °c is
$ rtl_433 -C si
This is my provisonal shack sporting the slimmest possible set up. A 5 Watt VHF /UHF handheld transceiver connected to OE5XFK in the Mountains of hell, as everybody should know meanwhile.
The fat USB stick is an #rtlsdr, a tiny software defined radio attached to a laptop running #ubuntu #linux 24.04.
And now we go a-hunting, Nearfield #SIGINT starting with a humble bash proggie.
