APRS-
ReCeiVing APRS DAtA
Each time a new APRS packet is received, the frequency
display is interrupted to show information as below:
Position comment (or 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 call sign.
• Press [DETAIL] to access further information.
• To restore the frequency display, press [ESC] or just wait for
approximately 10 seconds.
Note:
u
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.
u 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. If you receive a message that you
transmitted, “MY MESSAGE” will appear.
• If a received packet does not include new (or proper) APRS
data, the frequency display is not interrupted. An indicator
such as “dP” appears depending on the types of data. See the
table.
Indicator Meaning
dP Duplicate position comment
nP New position data
oP Other station position data
>P Beyond position limit
aM ACK message data
dM Duplicate message data
nM New message data
oM To other stations message data
rM Rejected Message
dS Duplicate status text
nS New status
Q? 1 Query
?? Packet that cannot be decoded
dD Duplicated DX cluster data
nD New DX cluster data
1 The transceiver automatically transmits the appropriate
information in approximately 2 minutes after receiving a request.
Note:
u
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.
u 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”.
