Now that we have Linux Packet software installed and Direwolf Configured we need to setup our AXPorts.
sudo nano /etc/ax25/axports
In my example I have created 3 ports. If you have never setup axports before you’ll see a few examples commented out with a # symbol before the line.
The layout is simple: portname callsign (with SSID) speed paclen window and description
Portname is the first. Choose a name you’ll remember. This for connecting direwolf to the ax25 apps and tools as you will see later.
Callsign is your callsign with dash and number for the SSID
Baudrate or Speed is the communication speed used. VHF/UHF is usually 1200, sometimes 9600, and HF is 300. Stick with 1200 for VHF/UHF and you really can’t go wrong
Paclen is more or less the length of info sent from you. Packet-radio.net/paclen/ has neat little description and history lesson. The TL;DR is 128 for VHF digipeater, 255 for direct, and 32 for HF.
Set window to 2
Finally the description so you know what that port is for and does.
Now that you have your axports setup you need to save and close. Using the CRTL-X command Y to save. Following the prompts at the bottom of the Nano Editor window.
