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 dir Generate log files in specified directory. Use "." for current directory.

-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.
t = GPS Tracker.
o = Output controls such as PTT and DCD.

-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.

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.

rtl_fm -f 144.39M -o 4 - | direwolf -n 1 -r 24000 -b 16 -
