The APRS system list specifies the various information for transmitting your position using analog APRS. As digital channels may use either DMR or analog APRS for position reporting, this list shares a namespace with the GPS system list. That is, the ID must be unique across both lists.

The 4th column specifies the period with which the position gets reported. The 5th and 6th columns specify the source and destination calls and SSIDs respectively. The 7th column specifies the path string. This is list of calls and SSIDs stored as a string without any separators. The 8th column specifies the map icon name.
