  • APRS operates at 144.390. You can do APRS on a user selected channel, but this is the standard that people transmit on.


  • If the application is not receiving APRS packets, it may be that it's not getting a good GPS signal. This combined with only seeing APRS stations within 50km can result in receiving aprsc (server) traffic, but the server not sending any APRS station traffic.

  • Direwolf can listen to the microphone on the computer (without plugging anything into the mic jack) and show APRS traffic on the terminal screen.
    • Had to sample the mic at 5hz. "Direwolf -r 5"
  • fldigi is mostly for HF radio, so it's not ideal for APRS, which operates at 1200 baud.
