I've just started learning about radio comms. I'm using the ARRL Handbook for Radio Communications 101, which is great so far.
My main goal is to detect the hydrogen line, or maybe some distant/noisy object (can amateurs pick up pulsars?). I also want to understand antennae much better, and maybe make a wire fractal antenna. I have a crazy idea about making a 3D fractal antenna-making bot from Lego or something! :D
(I'm not under any illusions about whether a fractal antenna is "better" but I just like the idea of them)
Thank you for the link! A pulsar or something "noisy but distant" in space is my goal, I think. The idea of being able to listen to distant stars is mind blowing to me, just amazing stuff.
There are a lot of open source projects. And technology (algorithms and receivers) wise it isn't too complicated nor a secret. That stuff is almost 100 years old.
An easy start is always looking at VHF reflection of strong transmitters that are not creating a lot of noise (like FM stations). ILS or VORs stations are classics.
