If you’re using Reticulum on amateur radio spectrum, you might want to use the AX.25 KISS interface. This way, Reticulum will automatically encapsulate it’s traffic in AX.25 and also identify your stations transmissions with your callsign and SSID.

Only do this if you really need to! Reticulum doesn’t need the AX.25 layer for anything, and it incurs extra overhead on every packet to encapsulate in AX.25.

A more efficient way is to use the plain KISS interface with the beaconing functionality described above.

[[Packet Radio AX.25 KISS Interface]]

type = AX25KISSInterface

# Set the station callsign and SSID

callsign = NO1CLL

ssid = 0

# Enable interface if you want use it!

interface_enabled = True

# Serial port for the device

port = /dev/ttyUSB2

# Set the serial baud-rate and other

# configuration parameters.

databits = 8

parity = none

stopbits = 1

# Set the modem preamble. A 150ms

# preamble should be a reasonable

# default, but may need to be

# increased for radios with slow-

# opening squelch and long TX/RX

# turnaround

preamble = 150

# Set the modem TX tail. In most

# cases this should be kept as low

# as possible to not waste airtime.

txtail = 10

# Configure CDMA parameters. These

# settings are reasonable defaults.
