And there she is in the dizzy light of the winter sun. A stern, prickly beauty throning high above smalltown suburbia. As you might have noted there is this usb black stick in front.

A SMB-socket on one side, on the other USB, so this might well be called a transgender stick. Linguistic/psychoanalytic sidenote: Even phallic verticals are grammatically female in most languages.

What for a start? Humble nearfield #SIGINT in an environment, I had the displeasure to come of age.

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.

ALL YOUR SENSORS ARE BELONG TO US!

well at least these shitbroadcasting on 433 MHz.

These are all weather stations and affiliated outdoor sensors all blaring out data on 433.920 MHz. No idea who owns these - yet.

Next we got to change this Fahrenheit mess to Celsius. And there are other sensors around, thankfully.

and poor man's #SIGINT

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
