APRX Configuration Notes:

Adding APRS-IS to RF exception

  • sudo vi /etc/aprx.conf
    • Go to line 391 (contains the line “filter f/KM4CNN-7/250 # allow Zeb to RF-igate if within 50km”)
    • Duplicate this line and add the corresponding callsign of the user
    • Save changes to /etc/aprx.conf
  • Restart APRX
    • sudo service aprx restart
  • Check the log to make sure you didn't break anything
    • watch -n2 tail -n40 /var/log/aprx/aprx-rf.log
    • If you don't see any R or T activity on the log then you probably broke something
  • You broke something?
    • sudo service aprx stop
    • sudo aprx -l -d -v
      • Watch for any errors output about configuration file problems
    • Fix your problems and then sudo service aprx restart
