How to Use a RTL-SDR and GQRX with a Raspberry Pi 3
Dev Miser
This video shows how to use a RTL-SDR software defined radio dongle with a Raspberry Pi 3 and GQRX open source software. It also shows how to overclock a Raspberry Pi 3 to maximize the performance of the setup.

Fascinating. The voice almost sounds as if she's auditioning for "I'm sorry, Dave, I can't do that!".
More seriously, the piece is now 9 months out of date. Shockingly, the terminal doesn't seem to be using TAB-completion where appropriate, nor suggesting the use of a script to load in the necessary libraries. The current RPi3 package will be available at https://github.com/csete/gqrx/releases, and installed according to the instructions at http://gqrx.dk/download/gqrx-sdr-for-the-raspberry-pi.
There is good stuff in the video, but out-of-date information, especially when undated, can be very misleading. To give an example, most information about using RTL-SDR dongles under Linux is now very much out-of-date. Installing a modern librtlsdr no longer requires manually adding udev rules, nor blacklisting kernel modules. [When a program is run which uses librtlsdr, kernel modules are automatically swapped as necessary.] However, most RTL-SDR information on the web is 5 years old and suggests doing things which are not only no longer necessary, but can make things fail. [On Ubuntu, the simplification is present as of 16.04, but was not available in 14.04.]
What is good is encouraging people to try using RTL-SDR dongles with the RPi3 and GQRX. But, please, use a real human as narrator!
