Dire Wolf

Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder. It can be used stand-alone to receive APRS messages, as a digipeater, APRStt gateway, or Internet Gateway (IGate). It can also be used as a virtual TNC for other applications such as APRSISCE/32, UI-View32, Xastir, APRS-TW, YAAC, UISS, Linux AX25, SARTrack, and many others.


  • Lower cost, higher performance alternative to hardware TNC.
  • 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.
  • Beaconing for yourself or other nearby entities.
  • Very flexible digipeating with routing between dual 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.
  • Runs in 2 different environments:
    • Microsoft Windows XP or later
    • Linux, regular PC or embedded systems such as Raspberry Pi
