Viewing APRS Messages

Besides the raw AX.25 packet view of incoming traffic, text message traffic can be viewed in four other optimized modes:

  1. showing actual APRS Message (APRS 1.0.1 spec chapter 14) messages, filtering out the acknowledgments.
  2. showing a filtered subset of messages and logging the messages to a file, per Robert Bruninga's Field Data Reporting initiative (
  3. showing an organized display of APRS bulletin notices.
  4. showing all messages originated by the local YAAC station.
