Page 13: Storing Status Text
STORING STATUS TEXT Status text is another comment to transmit with position data. Unlike a position comment, you can make any desired comment using a maximum of 20 alphanumeric characters. This transceiver has 3 memory channels for preprogramming. Note: Attaching a long comment can double the size and length of the packet. -
Page 14: Programming A Group Code
It does not matter whether or not the subsequent 4 digits match. The default on this transceiver is APK002; K002 stands for KENWOOD Ver. 2. Note: APRS packets, which are generated via various methods, include various codes instead of group codes. Using “All calls” allows you to receive packets which include the following codes. -
Page 15: Programming A Packet Path
PROGRAMMING A PACKET PATH A packet path specifies how APRS data should be transferred via one or more repeaters. A repeater, which is used for packet transfer, is commonly called a digipeater. This came from a digital repeater. A digipeater is usually located on a mountain top or high building. - Page 16 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;...

Page 20: Chapter 2 Aprs ® Message
The APRS supports a function for transmitting and receiving a message independent of position reports. You can transmit a message to a single station only or a bulletin to all other stations in your group. If you specify a station, the entered message is transmitted up to 5 times until an acknowledgment is returned. -
