APRS Callsign Query (Who-Is) Instructions

javAPRSQRZ was written to provide the amateur radio APRS community a simple, but effective, callsign lookup server for APRS-IS. As such, it does not offer many features that software written to function as a general client might offer such as status ports. It does, however, provide a multi-platform application tuned to present cleanly formatted packets to the APRS-IS feed.

  • Do a One Line Query

      • Send an APRS message to AD6NH-WI with the callsign as the only word in the message text.

      AD6NH-1>APRS::AD6NH-WI :ad6nh

  • Do a Multi-Line Query
      • Send an APRS message to AD6NH-WI with the letter F (case-insensitive) followed by a space and then the callsign.

      AD6NH-1>APRS::AD6NH-WI :f ad6nh
