Dire Wolf

Decoded Information from Radio Emissions for Windows Or Linux Fans

In the early days of Amateur Packet Radio, it was necessary to use a “Terminal Node Controller” (TNC) with specialized hardware. Those days are gone. You can now get better results at lower cost by connecting your radio to the “soundcard” interface of a computer and using software to decode the signals.

Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder. It can be used stand-alone to observe APRS traffic, as a digipeater, APRStt gateway, or Internet Gateway (IGate). It can also be used as a virtual TNC for other applications such as APRSIS32, UI-View32, Xastir, APRS-TW, YAAC, UISS, Linux AX25, SARTrack, RMS Express, and many others.

Features

  • Lower cost, higher performance alternative to hardware TNC. Version 1.2 decodes more than 1000 error-free frames from WA8LMF TNC Test CD.

  • Ideal for building a Raspberry Pi digipeater & IGate.

  • 300, 1200, and 9600 baud operation.

  • Interface with applications by - AGW network protocol - KISS serial port - KISS network protocol

  • Decoding of received information for troubleshooting.

  • Logging and conversion to GPX file format.

  • Beaconing for yourself or other nearby entities.

  • Very flexible Digipeating with routing and filtering between up to 6 ports.

  • APRStt gateway - converts touch tone sequences to APRS objects.

  • APRS Internet Gateway (IGate) with IPv6 support.

  • Compatible with software defined radios (SDR) such as gqrx and rtl_fm.

  • Includes separate raw packet decoder, decode_aprs.

  • Open source so you can see how it works and make your own modifications.

  • Runs in 3 different environments: - Microsoft Windows XP or later - Linux, regular PC or single board computer such as Raspberry Pi, BeagleBone Black, or cubieboard 2 - Mac OS X

Installation

Windows

Go to the releases page. Download a zip file with "win" in its name, unzip it, and run direwolf.exe from a command window.

Linux - short version for the impatient

Download the source, unpack the files and run:

cd direwolf-*
make
sudo make install
make install-conf

For more details see the User Guide in the doc directory. Special considerations for the Raspberry Pi are found in Raspberry-Pi-APRS.pdf
