I was sitting bored and fractious having spent too much time working when I found an article on air trafic control, i was that bored! One chap was talking about flight radar 24 so I went over to look. Very odd, had to ask why but raised my curiosity. There was a link to this dongle on Pimoroni and at less than ВЈ10 and having bought stuff from them before I ordered it thinking that will be fun after christmas. Just a few days later it turns up and it is really fun. I read more things and solderd up a new wire ariel and started to watch all the things flying around above me, there is a LOT of metal in the air!
Then a terrible thing, i read an article on Dc to daylight receivers. Just look it up. I should have got some shopping and was supposed to see family but I think that may be a bit difficult just now. There is so much more to listen to, so many things to do, it works on a pi and a 7year old debian netbook and if you can be bothered it will do tv and dab (here in this bit of norfolk your lucky if normal tv works with a high gain rooftop ariel and with other things to do, why bother)
So, whatever, for ВЈ10 old computers a pi go play. There is a ton of stuff to copy and paste so you do not even have to write your own, start with the link on the sales blurb. Then look at the rsgb! I started with computers before the internet, tinterwebs is amazing but i and many of my ilk still have a hankering for real wireless, 200 feet of wire and a can of oil. This thing is fantastic.
