APRS DATA COMMUNICATION (APRS BEACON)

◆ This function uses the APRS format for data communications including your station position, messages, etc.
◆ When data is received from another station, the direction of the received station (from your station’s perspective), their distance, and their grid
square locator is displayed. Any comments sent by the other station are also displayed.
◆ Meteorological data obtained from a connected Weather Station can be transmitted.
◆ APRS (Automatic Packet Reporting System) is a worldwide system introduced by Bob Bruninga, WB4APR .

NAVITRA DATA COMMUNICATION (NAVITRA BEACON)

◆ The Navitra system was introduced by KENWOOD in the 1990’s, for use within Japan.

CALLSIGN AND BEACON TYPE SETTINGS

◆ When an APRS/NAVITRA beacon is created, set the callsign and beacon type (APRS/NAVITRA) (Menu No. 600).
◆ SSID (Secondary Station IDentifi ers) can be added to the end of your callsign (for example, W6DJY will become W6DJY– 14).
SSIDs can range from “None, – 1” to “– 15”, so that each callsign can have up to 16 settings.
Refer to the website for SSID: http://aprs.org/aprs11/SSIDs.txt (as of October 2013)

DIGIPEAT

◆ The term digipeat means that the packet data is relayed. When a digipeater (relay station) receives a packet, it saves it to memory. When the
reception ends, the data is re-transmitted. Using digipeat, it is possible to send beacons long distances.
◆ In order to perform a digipeat, you must set up a packet path (Menu No. 612). For the packet path, you can specify a direct callsign or you can
use “WIDE1-1” or “WIDE1-1, WIDE2-1”, specifying a common alias and hops number. Set the transceiver’s packet path according to the digipeater
settings.
◆ Digipeat is very useful in reaching other stations when you have a weak signal. However, you need to set up the total hops numbers and beacon
transmissions moderately to prevent channel congestion.
WIDE type WIDE type:
This degipeater can send the packet over a wide area.
Fill-in type:
Regional degipeaters are also called “RELAY type” relays. These
degipeaters are used for mobile stations when a signal cannot
reach a WIDE-type degipeater.
