APRS – 3
RECEIVING APRS DATA
Each time a new APRS packet is received, the frequency
display is interrupted to show information as below:
• The received APRS packet may include information on
an object such as a hurricane or tornado. In this case (ex.
object), the name of the object appears instead of a call sign.
• To restore the frequency display, press
any key or just wait
for approximately 10 seconds. (You can change the time
through Menu No.3U1- Interrupt Time.)
Note:
X 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.
X When you receive an APRS position packet that you transmitted,
the frequency display is not interrupted. “My Position” will appear
on the display. This could happen when one or more digipeaters
are used.
X If you receive a message that you transmitted, “My Message” will
appear.
• If a received packet does not include proper APRS data, the
frequency display is not interrupted. An indicator such as
“dP” appears depending on the types of data. See the table.
• You can change the interrupt screen display setting through
Menu No. 3U0-Display Area.

Note:
X The APRS programs for PCs have entry fields for a position
comment and status text. The data entered to these two fields are
transmitted as separate packets. This transceiver, however, includes
both of a position comment and status text in one packet to transmit.
X This transceiver beeps each time it receives any type of APRS
packet. You may access Menu 3TO (Sound - RX Beep) to change
this setting. The default is “All”.
