Freqwatch v0.1

Introduction

• Explore vast regions of the RF spectrum

• Log radio activity to a mysql database for trend analysis

• Delegate scanners to find radio traffic and log it

• Delegate monitors to store interesting data in the database

Usage

• Install (see the INSTALL file)

• Use the 'blacklist' file to prevent frequency ranges from showing up in your database / output

• Configure some sticks as scanners using freqwatch.conf. Scanners scan frequency ranges and log signals above a defined threshold to the database, in the 'freqs' table.

• Configure other sticks as monitors by using the modified rtl_fm included. Use regular rtl_fm options to specify frequency ranges (several to scan different frequencies), etc. The output will be logged to the database 'intercepts' table.

• See the freqwatch.conf file for examples

• Use the intercept.py file in the rtl_fm_new directory to pull data from the monitor database. The monitor system still has problems (inserts blanks in the output...)

Security Note

You should run freqwatch in a controlled environment (e.g. with the web and database servers on localhost, and a firewall blocking the relevant ports from outsiders.)
