APRS-3
RECEIVING APRS DATA
Each time a new APRS packet is received, the frequency display
is interrupted to show information as below:
Status text
• The received APRS packet may include information on an object
such as a hurricane or tornado. In this case, the name of the object
appears instead of a callsign.
• Press [MSG] to send a message to the station.
• Press [DETAIL] to access further information.
• To restore the frequency display, press [ESC] or just wait for
approximately 10 seconds.
Note:
◆ When you receive an APRS packet including an “EMERGENCY” comment,
a different format of display from the above will appear and a different beep
will sound.
◆ When you receive an APRS position packet that you transmitted, the
frequency display is interrupted and “MY POSITION” will appear on the
display. This could happen when one or more digipeaters are used. (When
setting Menu No. 625 (DISPLAY AREA) to “ENTIRE”, “HALF”, or “OFF”, the
call sign of the digipeater station will not display.)
◆ If you receive a message that you transmitted, “MY MESSAGE” will appear.
• You can change the interrupt screen display setting through Menu
No. 625 (DISPLAY AREA). When set to “OFF”, the frequency display
is not interrupted. An indicator such as “dP” appears, depending on
the type of data. Refer to the table for details.

The transceiver automatically transmits the appropriate information in
approximately 2 minutes after receiving a request.
Note:
◆ The APRS programs for PCs have entry fi elds for a position comment and
status text. The data entered to these two fi elds are transmitted as separate
packets. This transceiver, however, includes both of a position comment and
status text in one packet to transmit.
◆ This transceiver beeps each time it receives any type of APRS packet. You
may access Menu 624 (AUDIO - RX BEEP) to change this setting. The
default is “ALL”.
