APRS – 16
SETTING TX BEACON
Q Packet Transmit Method
Access Menu 3D0.
Select the operation method for transmitting APRS
packets. The table concludes how operations differ
depending on the selection.
Manual:
Each press of [BCON] transmits your APRS packet.
PTT:
1 Press [BCON] to switch the function ON.
• “BCON” appears and blinks.
2 Press and hold [PTT], then speak into the
microphone.
3 Release [PTT].
• Releasing the switch transmits your APRS packet.
• You cannot retransmit an APRS packet unless the
time selected in < Initial Interval > passes. Wait until
“BCON” starts blinking to indicate transmitting is
ready.
4 To switch the function OFF, press [BCON] again.
Auto:
1 Press [BCON] to switch the function ON.
• “BCON” appears.
• Switching the function ON transmits your APRS
packet once. After that, APRS packets are
automatically transmitted at intervals of the period
selected in < Initial Interval >.
2 To switch the function OFF, press [BCON] again.
SmartBeaconing:
1 Press [BCON] to switch the function ON.
• “BCON” appears and blinks.
• After manually transmitting your station position
data 1 time, your position data will be automatically
transmitted using the time interval set under
“SmartBeaconing” (Menu Nos. 3F0 ~ 3G2).
2 To switch the function OFF, press [BCON] again.
Note: After setting “SmartBeaconing”, the TX Interval Time,
Decay Algorithm and Proportional Pathing features will no longer
operate.
Q Quick Beacon
When setting “Method” to any value other than
“Manual”, you can manually transmit the Beacon.
Press [F], [BCON] transmits your APRS packet.
Q Initial Interval Time
Access Menu 3D1.
You can change the interval for automatically
transmitting APRS packets. Select to 0.2, 0.5, 1, 2, 3,
5, 10, 20, or 30 minutes. The default is 1 minute.
Note:
X With “Auto” in < Method > and Beacon ON, pressing [
OK] to
complete the setting causes the APRS packet to be immediately
transmitted. After that, APRS packets are transmitted at intervals
of the selected period.
X While signals are present, an APRS packet is not transmitted
after the interval. Approximately 1 second after signals drop,
transmitting is executed.
SETTING ALGORITHM
Q Decay Algorithm
Access Menu 3E0.
This function continuously extends the packet
transmission interval in the case that there is no
change of position information.
• When the position data does not change, the data is
transmitted based on a Decay Algorithm (ex. Interval
Time = 1 minute: 2 minutes, 4 minutes, 8 minutes, 16
minutes, 32 minutes, 32 minutes, 32 minutes, etc.)
• When My station position data changes, the data is
transmitted using an interval time based on the set Initial
Interval or Proportional Pathing.
• When the set time elapses and transmission is performed
but a busy signal is present, the transceiver does not
transmit. When there is no longer a busy signal, the
transceiver attempts to transmit after 1 second.
Note:
X While transmitting by pressing the [PTT] switch, beacon
transmission is reserved.
X If My station call sign is not set, My station data will not be
transmitted.
X Depending on this interval, the transmission of the message will
become a 1 minute interval.
