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.
Why settle for mediocre receive performance from a 1980's technology TNC using an old modem chip? Dire Wolf decodes over 1000 error-free frames from Track 2 of the WA8LMF TNC Test CD, leaving all the hardware TNCs, and first generation "soundcard" modems, behind in the dust.
Dire Wolf is a modern software replacement for the old 1980's style TNC built with special hardware.
Without any additional software, it can perform as:
- APRS GPS Tracker
- Digipeater
- Internet Gateway (IGate)
- APRStt gateway
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, Winlink Express (formerly known as RMS Express, formerly known as Winlink 2000 or WL2K), BPQ32, Outpost PM, and many others.
-
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, Winlink / RMS Express, Outpost PM, and many others.
-
Uses computer’s “soundcard” and digital signal processing.
Lower cost and better performance than specialized hardware.
Compatible interfaces include UDRC, SignaLink USB, DMK URI, RB-USB RIM, RA-35, and many others.
-
Standard 300, 1200 & 9600 bps modems and more.
-
DTMF (“Touch Tone”) Decoding and Encoding.
-
Speech Synthesizer & Morse code generator.
Transmit human understandable messages.
-
Compatible with Software Defined Radios such as gqrx, rtl_fm, and SDR#.
-
Concurrent operation with up to 3 soundcards and 6 radios.
- Runs on Windows, Linux (PC/laptop, Raspberry Pi, etc.), Mac OSX.

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.
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
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
Results will vary depending on your hardware platform and operating system version because it depends on various volunteers who perform the packaging.
sudo yum check-update
sudo yum list direwolf
sudo yum install direwolf
Go to the releases page. Chose desired release and download the source as zip or compressed tar file. Unpack the files, with "unzip" or "tar xfz," and then:
cd direwolf-*
make
sudo make install
make install-conf

Read the User Guide in the doc directory. It is a lot more complicated than Linux.
If you have problems, post them to the Dire Wolf packet TNC discussion group. I don't have a Mac and probably won't be able to help you. I rely on others, in the user community, for the Mac version.
