Unlike a voice repeater, it operates on a simplex frequency. Each volunteer who installs a digipeater declares his (or her) digipeater to be a “wide” type or “relay” type. Generally a wide-type digipeater transmits packets over much greater distances than a relay-type one. The APRS supports various methods for specifying a packet path. Some of those methods are described on the next page. This transceiver allows you to edit a path using a maximum of 32 alphanumeric characters. The default is “RELAY,WIDE” that is one of the common settings. A comma must be put between each parameter. Note: This transceiver is incapable of functioning as a digipeater. 72 Wide-type Relay-type 1 Press [MENU] to enter Menu mode. 2 Press [2], [8] to select “2–8 (PACKET PATH)”. • The display for entering characters appears; the first digit blinks. 3 Press [UP]/ [DWN] to select a character. • You can enter 0 to 9, A to Z, , (comma), and –. 4 Press [OK].

Let us describe four basic methods for editing a packet path. 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”. In this example, APRS data is transferred to any relay-type digipeater near your position first, then to any wide-type digipeater. You can also program more than one “WIDE”. If you enter “WIDE,WIDE” for example, APRS data will be transferred to any wide-type near your position first, then to another wide-type. This method relieves you from specifying the call signs of digipeaters. Method 3 (WIDEN-N path): Program “WIDEN-N”, where both Ns indicate the number of wide-type digipeaters to be used for relay. If you enter “WIDE3-3” for example, APRS data will be relayed by three digipeaters in any direction. Note: This method is supported only by advanced APRS networks. Method 4 (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. Note: This method is supported only by advanced APRS networks.

PROGRAMMING A PACKET PA<strong>TH</strong><br />
A packet path specifies how APRS data should be<br />
transferred via one or more repeaters. A repeater, which<br />
is used for packet transfer, is commonly called a<br />
digipeater. This came from a digital repeater. A<br />
digipeater is usually located on a mountain top or high<br />
building. Unlike a voice repeater, it operates on a<br />
simplex frequency. Each volunteer who installs a<br />
digipeater declares his (or her) digipeater to be a “wide”<br />
type or “relay” type. Generally a wide-type digipeater<br />
transmits packets over much greater distances than a<br />
relay-type one.<br />
The APRS supports various methods for specifying a<br />
packet path. Some of those methods are described on<br />
the next page. This transceiver allows you to edit a path<br />
using a maximum of 32 alphanumeric characters. The<br />
default is “RELAY,WIDE” that is one of the common<br />
settings. A comma must be put between each<br />
parameter.<br />
Note: This transceiver is incapable of functioning as a digipeater.<br />
