so i'm trying to get this bloody thing set up for my mate.
when it's done it'll monitor overflying aircraft transmissions and upload the data to a website for people to see what's flying where.
I'm using raspbian stretch light - no desktop.
following these instructions:
https://radar.lowflyingwales.co.uk/raspberry-pi-installation-instructions/Currently got as far as installing the image, boots up fine.
However it won't connect to my wireless network.
When I look at the sdcard - both the ssh and wireless configuration files have vanished.
I can put them back, take the card out and put it back in and they are still there.
But everytime I booth the pi, they get deleted and hence, no internet connection.
HELP !
