Man, this seems like such a great resource; wish I had found it when I first got into SDR. I wrote a blog post about controlling ceiling fans using SDR (https://blog.hmac.io/2019/10/25/making-dumb-fans-smart-using-software-defined-radio.html https://blog.hmac.io/2019/10/25/making-dumb-fans-smart-using...), but I glossed over my initial struggles just getting up to speed with this stuff. All the concepts of SDR are straightforward and fairly intuitive, but it's the software stack and actually using the tools that's hard. The whole field is niche enough that you end up stubbing your toe with every step you take in that world. Googling around and trying to figure out where to even begin comes up with so many fragmented, unhelpful pieces of information. You either end up being pointed at Gnu Radio, which amounts to an incomprehensible behemoth for a newbie, or you find the numerous lighter weight pieces of software which aren't very clear on what exactly they're good for and are often unmaintained. Luckily my first project was rather simple; ceiling fan remotes don't exactly use the most advanced protocols. Once I found CubicSDR and fiddled around with it enough I was able to dump the radio signals to an audio file and just tease the rest out in Audacity. My blog post mostly covers the nightmare that was the TX side of things.
