RTL-SDR setup script v1

pisdr-v1.sh

#!/bin/bash

# This bash script installs all needed tools for using
# RTL2832U based DVB-T tuners as software defined
# receivers (SDR) on Debian/Ubuntu based systems
#
#	librtlsdr - basic library needed to communicate with RTL2832U  
#	dump1090 - ADS-B message decoder with web page google maps display of aircraft locations
#	multimon-ng - RF demodulator (can be used for decoding APRS packets)
