− | == Install Raspbian OS ==
| |
− | | |
− | * Follow the instructions here:
| |
− | ** https://www.raspberrypi.org/documentation/installation/installing-images/README.md
| |
− | | |
− | == Install pre-reqs and update raspberry pi to latest version ==
| |
− | | |
− | sudo apt-get update
| |
− | sudo apt-get upgrade
| |
− | sudo apt-get install git cmake libusb-1.0-0.dev build-essential
| |
− | sudo apt-get install lame libmp3lame-dev libvorbis-dev libshout-dev
| |
− | sudo rpi-update && sudo reboot
| |
− | | |
− | == Install the latest rtl-sdr code ==
| |
− | | |
− | This latest git release is needed for padding zeros when squelch is enabled (-E pad option)
| |
− | | |
− | git clone https://github.com/keenerd/rtl-sdr/
| |
− | cd rtl-sdr/
| |
− | mkdir build

− | | |
− | == Blacklist the kernel's bundled RTL drivers ==
| |
− | | |
− | We do this so we don't conflict with the RTL drivers we're about to install
| |
− | | |
− | sudo su -
