Explanation:
SmartBeaconing™ is a function that efficiently transmits an APRS beacon including your
own station position, speed and direction of travel. The information is based on data
from a GPS satellite receiver unit.
Set STATUS to TYPE1, TYPE2 or TYPE3; set [APRS] → [24 MY POSITION] to GPS;
and set [APRS] → [16 BEACON TX] to [SMART
function. (Operation is also possible by touching
APRS STATION LIST screen and then touching the [BEACON]).
If " " appears on the top-right corner of the APRS STATION LIST screen,

STATUS: SmartBeaconing

Set STATUS to OFF to deactivate SmartBeacon
The SmartBeaconing function on this transceiver has 3 different settings
(TYPE 1 to TYPE 3) and has preset initial values postulated to be used in
the following operation.
TYPE1: High speed movement, such as by vehicle.
TYPE2: Medium speed movement, such as by bicycle.
TYPE3: Low speed movement, such as by walking.
TYPE 2 and TYPE 3 settings (particularly TYPE 3) transmits many
beacons in a short period of time even if in comparatively slow
movement.
Because of this, using these setting during high speed movement, such
as by vehicle, causes many beacons being transmitted and may cause a
frequency jam.
Be sure to have settings on TYPE1 when in high speed movement.
LOW SPD: If speed is lower than which is set, BEACONs are transmitted in time
intervals set in [SLOW RATE].
The units for speed can be set in Set mode option [APRS] → [11 APRS
UNIT].
HIGH SPD: If speed is higher than which is set, BEACONs are transmitted in time
intervals set in [FAST RATE].
The units for speed can be set in Set mode option [APRS] → [11 APRS
UNIT].
SLOW RATE: BEACON transmission time interval when speed decreases below the
[LOW SPD] setting.
FAST RATE: BEACON transmission time interval when speed increases above the
[HIGH SPD] setting.
TURN ANGL: Set the minimal value of changes in angle when the direction of
movement changes.
