Here's a very good tutorial series. It's targeted at hackRF, but has plenty of general info. https://greatscottgadgets.com/sdr/ https://greatscottgadgets.com/s

  I'm working through his lessons. They're very good. I don't have a HackRF but I managed to get the "Hello World" flow, i.e., listen to FM broadcast radio going nicely with a cheap RTL-SDR by following lesson 1, but changing the sample rate. The version of GNU Radio in the Ubuntu apt-get repos for 18.04 is fairly recent but the GQRX project has a PPA which includes GNU Radio which will hopefully be updated more frequently. With default Ubuntu I had problems with the WX slider not moving. I didn't realize that WX widgets are old and the advice is to use QT. WX is removed in this latest version. FWIW, I've since switched to Kubuntu on the same hardware and all widgets work well including WX but I have followed advice and now use QT. The sound sink seems to work better if you bypass PulseAudio. Give the sink a device name, probably hw. I'm eagerly waiting for one of these that I preordered. https://airspy.com/airspy-hf-discovery/ https://airspy.com/airspy-hf-discovery/ I don't have it yet so I can't swear by it but every report from those who have one seems to be very good if you want a general purpose receiver. It covers 0.5 kHz (yes 500 Hz) to 31 MHz and 60 to 260 MHz so not as wide as some but ... I'm mostly interested in HF so plenty wide enough for me.
