#-------------- Direwolf Parameters --------------------------------------------
# You may use a tactical call sign for MYCALL for APRS.  If you do, you MUST set a valid call sign
# in COMMENTCALL so that a call sign is included in the APRS text.  Otherwise, COMMENTCALL
# may be left empty.
MYCALL="N0CALL-10"
COMMENTCALL=""
LOC="Bellingham, WA"
GRID="CN88ss"

# Direwolf supports both decimal degrees (e.g. -71.34717) format using the "."
# character (and negative values) as well as the degrees.minutes.seconds (e.g. 71^20.83W) 
# format using the "^" character (and the E/W indicator)
LAT="48.753318"
LONG="-122.472632"

# Rig power in watts
POWER=10
# Antenna height in feet from average terrain (not feet above sea level)
HEIGHT=40
# Antenna gain in dBi
GAIN=2

# Direwolf Audio sample rate in bits/second.  Depends on your soundcard - usually 44100 or 48000.
# Fe-Pi and DRAWS audio cards can use 96000:
ARATE="96000"
# Signalink:
#ARATE="48000"

#--------------- Direwolf Sound Card, PTT and rig control settings --------------------------------------------

# There are 2 ways to select the sound card.  The first way is to explicitly select the 
# card by assigning it to the AUDIO_DEV variable below:
#AUDIO_DEV=""
AUDIO_DEV="fepi-capture-right fepi-playback-right"

# The second way is to set the following variable, which this script will use as a 
# case-insensitive string to grep for (uniquely identify) the soundcard in "arecord -l" 
# output.  Typically, "USB AUDIO" works for USB sound cards like Signalink.  
# For Fe-Pi sound card, use "Fe-Pi".
AUDIO_DEV_SEARCH_STRING="Fe-Pi"

# If you set AUDIO_DEV="", then AUDIO_DEV_SEARCH_STRING will be used to find the audio card.
# Set AUDIO_DEV if you want to use a virtual sound card.  AUDIO_DEV_SEARCH_STRING is ignored
# if AUDIO_DEV is set.

# PTT Options and Examples:
# 1. The sound card handles PTT via VOX (e.g. SignalLink), so set to empty string.
#    PTT0=""
# 2. Use General Purpose I/O (GPIO) BCM pin (not the physical pin number) and potentially a 
#    relay/transistor (e.g. UDRC/DRAWS/DigiLink)
#    PTT0="PTT GPIO 12"
# 3. Use USB serial port adapter and control RS-232 signal lines (DTR, RTS)
#    PTT0="PTT /dev/ttyUSB0 RTS"
# 4. Use the HamLib rig control library (open source) using a serial port or rigctld server
#    See the HamLib and Direwolf documentation for details
#    PTT0="RIG 120 /dev/ttyUSB0"
#    PTT0="RIG 7 localhost:4532"

# DEVSTRING is the case-insensitve string to search for in /dev/serial/byid that
# is the serial port used for rig control (if rig control is used)

## DigiLink or UDRC/DRAWS.  PTT0 is for left audio channel and PTT1 for right.
## If using a single audio channel, set PTT0
PTT0="PTT GPIO 23"
#PTT1="PTT GPIO 12"
DEVSTRING=""

## Signalink (Signalink uses VOX between computer and Signalink)
#PTT0=""
#PTT1="$PTT0"
#DEVSTRING=""

## USB/Serial interface for radio rig control
## Kenwood TM-D710G
#DEVSTRING="USB-Serial"
#RIGCTL_RADIO=234
#RIGCTL_SPEED=57600
#PTT0=""

## USB/Serial interface for radio rig control
## Icom IC-7100
#DEVSTRING="_A-if00-port0"
#RIGCTL_RADIO=370
#RIGCTL_SPEED=19200
#PTT0="PTT RIG 2 localhost:4532"
#PTT1="$PTT0"

#----- ARDOP (piardop2) Sound Card and PTT settings ---------------------------------------------

ARDOP_PORT=8515

## I haven't tested PulseAudio devices defined in PulseAudio, but they should work.
## Or, to use the plughw device, run 'arecord -L' to get the device name.
ARDOP_DEV="fepi-capture-right fepi-playback-right"
#ARDOP_DEV="plughw:CARD=Audio,DEV=0 plughw:CARD=Audio,DEV=0"

## Pick ONE of the following three PTT types (GPIO, CAT, or Serical) for ARDOP:

## GPIO PTT...
## For DigiLink/UDRC/DRAWS: Left radio is GPIO (BCM) 12, right radio is 23
#ARDOP_PTT="-p gpio=12"
ARDOP_PTT="-p gpio=23"

## ...or CAT Commands for rigs that support CAT...
## ARDOP requires specific CAT commands to key/unkey the radio via CAT.  It can't
## use rigctld.  These are the key/unkey CAT commands for most ICOM radios:
#ARDOP_DEVICE="/dev/ttyUSB0"
#ARDOP_KEY="-k FEFE88E01C0001FD"
#ARDOP_UNKEY="-u FEFE88E01C0000FD"
#ARDOP_CAT_PORT_SPEED=19200
#ARDOP_PTT="-c $ARDOP_DEVICE:$ARDOP_CAT_PORT_SPEED $ARDOP_KEY $ARDOP_UNKEY"

## ...or RTS serial PTT control for rigs that support it.
#ARDOP_DEVICE="/dev/ttyUSB0"
#ARDOP_CAT_PORT_SPEED=19200
#ARDOP_PTT="-c $ARDOP_DEVICE:$ARDOP_CAT_PORT_SPEED"

# Filter below says:  Transmit only messages destined for stations within 16KM (10 miles)
# of this station's LAT/LONG, or anyone we've heard in the last hour [i/60/0] AND the addressee
# must have a callsign that starts with W,K,A, or N.
# Individual message filter format is: i/time/hops/lat/lon/km
# Allow “messages” for a station heard over the radio in the last ‘time’ minutes 
# within the specified distance. Distance can be digipeater hops and/or geographical distance.
# Typical time limits might be 30 or 60 minutes. If we haven’t heard from a station for that 
# long, it’s probably no longer hearing us. ‘hops’ is the number of digipeater hops necessary 
# to hear the message addressee.  If hops is not specified, the maximum transmit 
# digipeater hop count, from the IGTXVIA configuration will be used.
