SDR and GNU radio has always sounded interesting to me ever since I heard it mentioned on the Security Now podcast years ago. Does anyone know of good resources on how to get started? This is something I’d love to tinker with one day. I also don’t know a great deal about RF communication in general.

I looked into this last year, and the process seems to be "get at least half an undergrad degree in signal processing and then read the code." GNU Radio is really powerful, but most of the tutorials out there are "rest of the fucking owl" style[0]. Which I then realized makes sense, given the complexity of the domain. So be aware it's a deep subject and you won't be decoding new satellites in a few clicks unless you're copying somebody else's homework.

Buy a dongle and antenna from here: https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/ https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/ Install GNURadio, start playing with gqrx and FM reception. Buy a cheap radio controlled thingy, install SDR# with the plugins package and RTL_433 plugin for it and start playing.
