NAME

       direwolf - Soundcard TNC for packet radio.

SYNOPSIS

       direwolf [ options ] [ - | udp:9999 ]

       The  first audio channel can be streamed thru stdin or a UDP port.  This is typically used
       with an SDR receiver.

DESCRIPTION

       direwolf  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  APRSIS32,
       UI-View32,  Xastir,  APRS-TW,  YAAC,  UISS,  Linux  AX25,  SARTrack, RMS Express, and many
       others.

OPTIONS

       -c file
              Read configuration file from specified location rather than the default locations.

       -l logdir
              Generate daily log files in specified directory.  Use "." for current directory.

       -L logfile
              Generate single log file with fixed name.

       -r n   Audio sample rate per second for first channel.  Default 44100.

       -n n   Number of audio channels for first device.  1 or 2.  Default 1.

       -b n   Audio sample size for first channel.  8 or 16.  Default 16.

       -B n   Data rate in bits/sec for first channel.  Standard values are 300, 1200, 9600.
                     If < 600, tones are set to 1600 & 1800.
                     If > 2400, K9NG/G3RUH scrambling is used.
                     Otherwise, AFSK tones are set to 1200 & 2200.

       -D n   Divide audio sample by n for first channel.

       -d x   Debug options.  Specify one or more of the following in place of x.
                     a = AGWPE network protocol client.
                     k = KISS serial port client.
                     n = Network KISS client.
                     u = Display non-ASCII text in hexadecimal.
                     p = Packet dump in hexadecimal.
                     g = GPS interface.
                     W = Waypoints for position or object reports.
                     t = Tracker beacon.
                     o = Output controls such as PTT and DCD.
                     i = IGate
                     h = Hamlib verbose level.  Repeat for more.

       -q x   Quiet (suppress output). Specify one or more of the following in place of x.
                     h = Heard line with the audio level.
                     d = Decoding of APRS packets.

       -t n   Text colors.  1=normal, 0=disabled.

       -p     Enable pseudo terminal for KISS protocol.

       -x     Send Xmit level calibration tones.

       -U     Print UTF-8 test string and exit.

       -S     Print Symbol tables and exit.

       -a n   Report audio device statistics each n seconds.

EXAMPLES

       gqrx (2.3 and later) has the ability to send streaming  audio  through  a  UDP  socket  to
       another  application  for  further  processing.   direwolf can listen over a UDP port with
       options like this:

              direwolf -n 1 -r 48000 -b 16 udp:7355

       Other SDR applications might produce audio on stdout so it is convenient to pipe into  the
       next application.  In this example, the final "-" means read from stdin.
