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 an expensive “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, BPQ32, Outpost PM and many others.

Features & Benefits

Dire Wolf includes:

Beaconing, Tracker, Telemetry Toolkit.

Send periodic beacons to provide information to others. For tracking the location is provided by a GPS receiver. Build your own telemetry applications with the toolkit.
APRStt Gateway.

Very few hams have portable equipment for APRS but nearly everyone has a handheld radio that can send DTMF tones. APRStt allows a user, equipped with only DTMF (commonly known as Touch Tone) generation capability, to enter information into the global APRS data network. Responses can be sent by Morse Code or synthesized speech.
Digipeaters for APRS and traditional Packet Radio.

Extend the range of other stations by re-transmitting their signals. Unmatched flexibility for cross band repeating and filtering to limit what is retransmitted.
Internet Gateway (IGate).

IGate stations allow communication between disjoint radio networks by allowing some content to flow between them over the Internet.
AX.25 v2.2 Link Layer.

Traditional connected mode packet radio where the TNC automatically retries transmissions and delivers data in the right order.
KISS Interface (TCP/IP, serial port, Bluetooth) & AGW network Interface (TCP/IP).

Dire Wolf can be used as a virtual TNC for applications such as APRSIS32, UI-View32, Xastir, APRS-TW,YAAC, UISS, Linux AX25, SARTrack, RMS Express, Outpost PM, and many others.

Latest Development Version

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.

For more details see the User Guide in the doc directory.

Linux - Using git clone (recommended)

cd ~
git clone https://www.github.com/wb2osz/direwolf
cd direwolf
make
sudo make install
make install-conf

This should give you the most recent stable release. If you want the latest (possibly unstable) development version, use "git checkout dev" before the first "make" command.

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

Linux - Using apt-get (Debian flavor operating systems)

Results will vary depending on your hardware platform and operating system version because it depends on various volunteers who perform the packaging.

sudo apt-get update
apt-cache showpkg direwolf
sudo apt-get install direwolf

Linux - Using yum (Red Hat flavor operating systems)
