Thanks Craig,
I changed all instances of DIGI or #DIGI in the etc/AX25/ files that I found with grep.
I also changed my callsign to then NODE name which I randomly chose as CANOE.
I'm confused by the difference between MYCALL and NODE. The instructions in the direwolf.node.conf file suggest changing the call to the node name.
Should my NODE name be my call sign K2LJL-4 that was initially in the direwolf.node.conf file? Or should I change all instances of my call with my NODE name that I chose.
This is what it is beaconing now.
