# wb2osz/direwolf

Dire Wolf is a software "soundcard" AX.25 packet modem/TNC and APRS encoder/decoder. It can be used stand-alone to observe APRS traffic, as a tracker, digipeater, APRStt gateway, or Internet Gateway (IGate).   For more information, look at the bottom 1/4 of this page and in https://github.com/wb2osz/direwolf/blob/dev/doc/README.md

## What it is
Dire Wolf is a software soundcard AX.25 packet modem/TNC and APRS encoder/decoder written in C. It replaces hardware TNCs, decoding radio signals via a computer's audio interface, and can act as an APRS tracker, digipeater, IGate, or APRStt gateway.

## Use cases
- decode APRS packet radio traffic with a soundcard instead of a hardware TNC
- run an APRS IGate to bridge RF traffic to the internet
- operate a digipeater on a Raspberry Pi
- build a GPS beacon tracker for ham radio
- serve as a virtual TNC for applications like Xastir or Winlink Express
- use FX.25 forward error correction for weak-signal packet communication

## When to choose
- you want a low-cost software replacement for a hardware TNC
- you run APRS on Linux, Windows, or a Raspberry Pi
- you need high decode performance with FEC support (FX.25/IL2P)

## When to avoid
- you need a plug-and-play hardware TNC without a computer
- you work with protocols outside AX.25/APRS packet radio

## Facets
- artifact type: application
- maturity: active
- function: networking, serialization
- domain: embedded-systems, networking
- platform: windows, iot, cross-platform
