These instructions show you how to purchase and setup a completely self contained Raspberry Pi with an RTL-SDR stick(s) to broadcast a live audio feed to Broadcastify.com
Contents
Purchase Equipment
Raspberry Pi 2 Model B Project Board - 1GB RAM - 900 MHz Quad-Core CPU
RTL-SDR - RTL2832U & R820T USB Stick
Male MCX Connector to...
- F Female - http://amzn.to/1KtVwIt

Power Supply for Raspberry Pi
Memory Card for Raspberry Pi
Case for Raspberry Pi
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 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 cd build cmake ../ make sudo make install sudo ldconfig sudo mv $HOME/rtl-sdr/rtl-sdr.rules /etc/udev/rules.d/rtl-sdr.rules
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 - echo "blacklist r820t" >> /etc/modprobe.d/dvb-blacklist.conf echo "blacklist rtl2832" >> /etc/modprobe.d/dvb-blacklist.conf echo "blacklist rtl2830" >> /etc/modprobe.d/dvb-blacklist.conf echo "blacklist dvb_usb_rtl28xxu" >> /etc/modprobe.d/dvb-blacklist.conf exit
Install and configure ezstream
sudo apt-get install ezstream
Create this configuration file at /etc/ezstream_bcfy.xml and replace with your mount, password, and stream name
<ezstream> <url>http://audio#.broadcastify.com:80/your_mount</url> <sourcepassword>your_source_password</sourcepassword> <format>MP3</format> <filename>stdin</filename> <svrinfoname>Stream Name</svrinfoname> <svrinfourl>http://www.broadcastify.com</svrinfourl> <svrinfogenre>Scanner</svrinfogenre> <svrinfodescription></svrinfodescription> <svrinfobitrate>16</svrinfobitrate> <svrinfochannels>1</svrinfochannels> <svrinfosamplerate>22050</svrinfosamplerate> <svrinfopublic>0</svrinfopublic> </ezstream>
