       | start by reading a textbook on electronic communication? My
       | background is "EE"CS, with 90% being cs.

         | I used gnuradio to decode a remote control to a device that
         | allowed me to then automate. I now use a Great Scott Gadgets
         | YARD Stick One to transmit along with rfcat and python. A
         | generic RTL-SDR device with gnuradio worked on the decoding
         | part.
         | 
         | I found some good online resources to understand how to do the
         | decoding (e.g. learning the different protocols used). You can
         | dive into more theory (FFT etc.) of course. It was a winter
         | break project. Pretty fun. But be warned SDR generally can be a
         | deep rabbit hole.
         | 
         | One note: gnuradio is a shockingly bloated suite of software,
         | so pick a machine you don't mind getting tons of new packages.

           | 
           | Sounds like a good thing to use docker for.

           | If you don't need to transmit, you can get an RTL-SDR dongle:
           | it's way cheaper than an HackRF and fully supported as source
           | by GNURadio

         | The best thing about GNU Radio is that you can connect boxes
         | without really understanding them, or the math behind them.
         | 
         | There are many howtos and YouTube videos you can watch, and
         | start picking up a little here and there. It doesn't have to be
         | a steep learning curve.

         | GNU Radio supports audio I/O. You can use it with your laptop,
         | or desktop, and speakers/mic to just build an intuitive
         | understanding of quite a few things, without spending any money
         | on hardware.
         | 
         | The $30 SDR is an amazing source of samples once you get past
         | that point. It's quite amazing how much you can do with the the
         | pair of GNU Radio and the RTLSDR. I built a receiver/display of
         | VOR aircraft navigation signals, for example.

       | GNURadio is a fantastic project. I wish I had it many years while
       | I was studying digital communications at university. I am quite
       | busy, but one of my to-do project is to write a digital mode
       | (FT8, WSPR, etc) decoder with GNURadio
