This item selects the automatic transmission method of the APRS beacon.
When this item is set to “OFF” (no icon), your APRS beacon does not
transmit automatically. The FTM-350 only transmits your APRS beacon when the [B-TX] key is pressed.
When this item is set to “ON (FIX)”, the “ ” icon appears on the
display, and the APRS beacon transmits in accordance with the interval determined by “2 INTERVAL” of the Set Mode item “E14 BEACON TX”.
When this item is set to “SMART” (“” icon appears on the display),
the APRS beacon transmits in accordance with the interval determined
by Set Mode item “E33 SmartBeaconing”.
INTERVAL:
This item sets the interval time to transmit the APRS beacon automatically when “1 AUTO” of the Set Mode item “E14 BEACON
TX” is set to “ON (FIX)”.

FTM-350 SERIES APRS® MANUAL

APRS/PKT SET MODE
PROPORTIONAL: This item enables changing the transmit APRS beacon path route automatically according to the “INTERVAL” time determined from the
item of this Set Mode.
For example, if you set this item to “ON” when Set Mode item “E19
DIGI PATH SELECT” is set to “WIDE - 1-1, WIDE - 2-1”, and the
“INTERVAL” item is set to “5min”, the APRS beacon path changes
as follows:
a. 5 minute
WIDE - 1-1, WIDE - 2-1
b. 10 minute (none)
c. 15 minute WIDE - 1-1
d. 20 minute (none)
e. 25 minute WIDE - 1-1, WIDE - 2-1
repeats steps b - e afterward
When the Set Mode item “E19 DIGI PATH SELECT” is set to “OFF”,
“FULL1”, or “FULL2”, this item is ignored.
DECAY:
This function extends the interval of the APRS beacon when the vehicle is stopped.
Setting this item to “ON”, extends the setting value of the “INTERVAL” item step by step when the vehicle is stopped.
For example, if the “INTERVAL” item is set to “1min”, then when the
vehicle was stopped the interval time extend to “2 min”  “3 min” 
“5 min”  “10min”  “15min”  “20min”  “30min”  “30min”
... (the “60min” is not selected).
When the “INTERVAL” item is set to “30min” or “60min”, this item
is ignored.
LOW SPEED:
This item determines the threshold speed to judge the stop state of
your vehicle.
When the vehicle speed is lower than a selected speed, the FTM-350
considers the vehicle has stopped. (The speed unit is determined from
the Set Mode item “E11 APRS UNIT”).
RATE LIMIT:
This item determines the time to delay the automatic transmission of a
APRS beacon.
For example, if the vehicle moves after an APRS beacon automatically transmitted by the DECAY function when the vehicle was
stopped, the FTM-350 may transmit the APRS beacon twice in a short
time. The second transmission may be delayed by enabling this item.
Important Note: When the AUTO item is set to “SMART” (SmartBeaconingTM is activated), the INTERVAL, PROPORTIONAL, DECAY, LOW SPEED, and RATE LIMIT
items are ignored.

APRS/PKT SET MODE
E33: SmartBeaconing
Function:
Selects the various parameters of the SmartBeaconingTM.
The SmartBeaconingTM function regulates the APRS beacon transmissions based on the received GPS data (Movement speed, and movement direction etc.).
Available Values: 1 STATUS: OFF, TYPE1, TYPE2, or TYPE3
2 LOW SPEED: 2 ~ 30
3 HIGH SPEED: 3 ~ 70
4 SLOW RATE: 1 min ~ 100 min
5 FAST RATE: 10 sec ~ 180 sec
6 TURN ANGLE: 5° ~ 90°
7 TURN SLOPE: 1 ~ 255
8 TURN TIME: 5 sec ~ 180 sec
Default:
1 STATUS: OFF
2 LOW SPEED: 5
3 HIGH SPEED: 70
4 SLOW RATE: 30 min
5 FAST RATE: 120 sec
6 TURN ANGLE: 28°
7 TURN SLOPE: 26
8 TURN TIME: 30 sec
STATUS:
These resisters sum up (combine) the “LOW SPEED” through “TURN
TIME” items parameters in the “TYPE 1”, “TYPE 2”, or “TYPE 3”
settings.
When STATUS is set to “TYPE 1”, “TYPE 2”, or “TYPE 3”, the
SmartBeaconingTM is activated with parameters of that setting.
When STATUS is set to “OFF”, the SmartBeaconingTM function is
disabled.
LOW SPEED:
This item designates the lower speed threshold. The FTM-350 transmits an APRS beacon when your vehicle speed becomes lower than
the selected speed. The transmission interval time of the APRS beacon is set in “SLOW RATE” item. (The speed unit is determined from
the Set Mode item “E11 APRS UNIT”.)
HIGH SPEED:
This item designates the higher speed threshold. The FTM-350 transmits an APRS beacon when your vehicle speed becomes higher than
the selected speed. The transmission interval time of the APRS beacon is set in “FAST RATE” item. (The speed unit is determined from
the Set Mode item “E11 APRS UNIT”.)
SLOW RATE:
This item designates the transmission interval time of the APRS beacon at low vehicle speeds.

FTM-350 SERIES APRS® MANUAL

APRS/PKT SET MODE
FAST RATE:

This item designates the maximum transmission interval time of the
APRS beacon at high vehicle speeds.
TURN ANGLE:
This item designates the course change angle that indicates a progress
heading change.
TURN SLOPE:
This item sets a coefficient to modify the TURN ANGLE algorithm,
thus increasing the beacon rate for lower vehicle speeds.
When this setting value is increased, the threshold angles of the APRS
beacon timing are increased as the vehicle velocity is decreased.
TURN TIME:
This item designates the minimum delay time between each APRS
beacon. The FTM-350 does not transmit an APRS beacon until this
setting time has elapsed since the previous APRS beacon transmission, preventing too frequent beacon transmissions.
Note: In the factory, the same default parameter, suitable for mobile operation are saved in
TYPE1, TYPE2 and TYPE3 registers. You may customize the parameters of each register
for differing situations such as highway travel, urban routes, etc.

distance order.
Note: The sorted Station List automatically returns to “TIME” order when the transceiver is
turned off.

RNG RINGER:

Only the APRS beacons from the VOIP station, such as WiRES stations are displayed.
Only the APRS beacons from the weather stations are displayed.
Only the APRS beacons transmitted from a Yaesu transceiver, such as
the VX-8D, FTM-350 etc. are displayed.
Only APRS beacons of the STATUS stations including RAW NMEA
data, and APRS Beacons including packet data (except APRS beacon
data) are displayed.
Note: To display the stations including the packet data (except the
APRS Beacon data), it is necessary to set the “OTHER” parameter of
Set Mode item “E03 APRS FILTER” to “on”.
The FTM-350 displays only the APRS beacons of the “CALL
RINGER” stations, which are, entered into Set Mode item “E09 APRS
RINGER (CALL)”.
The FTM-350 displays only the APRS beacons of the “RNG RINGER”
stations which are defined via the Set Mode parameters of “E08 APRS
RINGER”.
