Let us describe five basic methods for editing a packet
path. Methods 3 to 5 are supported only by advanced
APRS networks.
Method 1 (Specific Path):
Program the call signs of one or more digipeaters in the
sequence of transfer relay; ex. “KD6ZZV,KF6RJZ”.
Method 2 (Generic Path):
Program RELAY and/or WIDE; ex. “RELAY,WIDE” (or
simply “R,W”). In this example, your APRS packet is
transferred to any RELAY digipeater near your position
first, then to any WIDE digipeater. You can also program
more than one WIDE. If you enter “WIDE,WIDE” for
example, your APRS packet will be transferred to any
WIDE near your position first, then to another WIDE.
Method 3 (WIDEN-N Path):
Program WIDEN-N, where both Ns indicate the number
of WIDE digipeaters to be used for relay. If you enter
“WIDE3-3” (or simply W3) for example, your APRS
packet will be relayed by three WIDEs in any direction.
Method 4 (TRACEN-N Path):
The operation is the same as WIDEN-N except that
digipeaters add their call signs to your packet before
forwarding. You may program “TRACE3-3” (or simply
T3) for example.
Method 5 (SSID Path):
Program a single number 1 to 15. You can easily specify
the number of digipeaters that will be used for relay. You
can also specify which directions of digipeaters relative
to your position will be used. See the table.
1
The first digipeater which receives your APRS data specifies
the entire route to the destination before forwarding; often 2
digipeaters are used in total.
2
The digipeater which receives your APRS data specifies the
call sign of the next digipeater before forwarding. This is
repeated until your APRS data reaches the destination.
