The Destination filter allows you to look only at traffic addressed to specific AX.25 stations or identifying specific APRS transmitter types (tocalls). Note that the destinations for Mic-E packets are not saved, since they vary constantly to contain latitude values for mobile stations.
By default, all possible destinations are enabled. However, you can turn off selected destinations, or turn off all destinations and selectively re-enable only specific addresses. The filter also reports the number of messages sent to each address and the number of unique stations (transmitting callsign-SSIDs) using each tocall value, and allows you to choose how the list of addresses is sorted (by clicking on the column headings).
You can also add tocalls that have not been seen yet to the destination list, so that APRS recording files can be played back with filtering.
