APRS – 17
Q Proportional Pathing
Access Menu 3E1.
This function automatically changes the transmit packet
path with the elapsed time.
Operation example for when <Proportional Pathing> = ON
Transmission interval is 1 minute. (When the <Decay
Algorithm> = ON, the decay transmission interval takes
precedence.)
The packet path changes with each transmission as
shown below (when the packet path is set as WIDE1-1,
WIDE2-1).
1 minute : DIRECT
2 minutes : WIDE1-1 (1 Hop)
3 minutes : DIRECT
4 minutes : WIDE1-1, WIDE2-1 (2 Hops)
5 minutes : DIRECT
6 minutes : WIDE1-1 (1 Hop)
7 minutes : DIRECT
8 minutes : WIDE1-1, WIDE2-1 (2 Hops)
This is repeated.
When jointly using a Decay Algorithm, if the speed is 1 knots
or slower, a Decay Algorithm pattern is used for transmitting,
but if the speed is 3 knots or faster, it changes to Proportional
Pathing.
SETTING SmartBeaconing
TM
Set to use “SmartBeaconing” (Menu 3D0) with APRS data
transmission.
This function optimizes beacon transmission based on
driving direction and speed. Use this function when you
want to track your transmissions, especially for optimizing
crossover beacon transmission intervals.

Q Low speed / High speed
Access Menu 3F0.
Low speed setting (2 ~ 30 <mi/h, km/h or knots>).
When the speed is lower than this, beacons are
transmitted at the time interval specified under “Slow
Rate”.
High speed setting (2 ~90 <mi/h, km/h or knots>).
When the speed is faster than this, beacons are
transmitted at the time interval specified under “Fast
Rate”.
Note: To select the speed setting of the units, access Menu 3V0
(Units 1 - Speed, Distance).
Q Slow rate
Access Menu 3F1.
Low speed transmission interval time
(1 ~ 100 minutes).
Q Fast rate
Access Menu 3F2.
High speed transmission interval time
(10 ~ 180 seconds).
Q Turn angle
Access Menu 3G0.
Driving direction change, minimum value setting
(5 ~ 90 degrees).
Q Turn slope
Access Menu 3G1.
Driving direction change, additional value setting
(1 ~ 255 (10degrees/speed)).
Q Turn time
Access Menu 3G2.
Minimum time delay between each beacon
transmission (5 ~ 180 seconds).
Note:
X When Menu 331 is set to a value other than [GPS], it operates at
the <Slow Rate>.
X Adjust the Setting values to match the actual driving status.
