Interesti project, what is the purpose of trying the thin client? Guessing whilst testing system antenna position temporary but see a few aircraft still shown.

Back to WW2 tactics, lookouts with binoculars noting details with pencil in a notebook then calling a central contact who will then disseminate info to nearby parties
You are right. The Radio was Generic DVB-T and the antena was the mag-mout whip supplied with the DVB-T, It was placed indoors on a cookie-can lid, just a meter away from the dongle (the length of coax of antenna is only one meter)
[SOLVED] faup1090 is now working on HP Thin-Client 520 As well as on Desktop PC.
Downloaded a fresh copy of SLAX image, prepared microSD card with this image, and booted Slax on Desktop PC. Installed piaware & dump1090-fa as user root, and faup1090 failed again.
Re-imaged again, but this time, did NOT install piaware & dump1090-fa as user root. Instead created user abcd, switched to user abcd, and then installed piaware & dump1090-fa The faup1090 is working OK now
Current version of SLAX is based on Debian 11.3 Bullseye. It is an excellent lightweight distro, fast boot, which can be run from a USB flash memory or microSD card+USB card reader. By default it runs with persistance, but has option to change to run without persistance or totally from RAM to be selected at boot by pressing Esc button.
It also has a Network Manager icon on Desktop, and by running it, the network (wire/wifi/Bluetooth) can be configured easily, like settings in standard Debian Desktop.
