94PACKET PATH AND DIGIPEATERA packet path specifies how APRS packets should betransferred via one or more repeaters. A repeater, whichis used for packet transfer, is commonly called adigipeater. This came from a “digital repeater”. Adigipeater is usually located on a mountain top or highbuilding. Unlike a voice repeater, it operates on asimplex frequency. Each volunteer who installs adigipeater programs it either as a WIDE or RELAY type.Generally a WIDE transmits packets over much greaterdistances than a RELAY.In any given area, there should be only one WIDE not tocause extra traffic or collisions on frequencies. A WIDEis capable of transferring packets from and to adjacentWIDEs. Like a WIDE, there should be only one RELAYin a given area; that area is usually much smaller than aWIDE. So, transmit packets to a RELAY when youcannot directly reach any WIDE. The RELAY then willtransfer the packets to any accessible WIDE.On this transceiver, you can edit a packet path using amaximum of 79 alphanumeric characters. The default is“RELAY,WIDE” that is one of the common settings. Withthis setting, packets will be transferred to a RELAY first,then to a WIDE.The APRS supports various methods for specifying apacket path. Some of those methods are described onpage 24.This transceiver with a built-in TNC may be used as adigipeater. See page 27.Note: To serve for mobile stations who always use the RELAY,WIDEpath, most WIDEs also respond to packets addressed to a RELAY.WIDE-typeRELAY-type
