Introduction

gr-scan is a program written in C++, and built upon GNU Radio, rtl-sdr, and the OsmoSDR Source Block. It is intended to scan a range of frequencies and print a list of discovered signals. It should work with any device that works with that block, including Realtek RTL2832U devices. I developed this software using a Compro U620F , which uses an E4000 tuner. That product doesn't seem to be available on the US site, but the Newsky DVB-T Receiver (RTL2832U/E4000 Device) has good reviews. The current version of gr-scan is: 2012082301.

Building and Running

These instructions are intended for a GNU/Linux installation, however it should be possible to adapt gr-scan for use on other platforms.
