article 3/2026: 1090 MHz ADS-B (Mode S Extended Squitter)

Digital modes are intresting. So I put up my personal flight radar by using software defined radio stick and some cable and with little dipole antenna with air choke to prevent noise from the cable. And after little thinkering I got it working quite nicely.

I also wanted to use some graphical map , so I made from source tarr1090 for this purpose.

Technical information::

- tarr1090 software
- readsb software
- rtl software for usb stick
-max range > 250km
- half vawe dipol antenna
- with vertical polarisation

Terminal use

And like allways there is enough terminal commands to create networking services and other cool stuf to learn more of these digital signals and about their modulations etc.
