the selected speed. The transmission interval time of the APRS beacon is
set in "SLOW RATE" item. The speed unit is determined from the APRS/
GPS Set Mode Item 10: APRS UNIT.
HIGH SPD: This item designates the higher speed threshold. The VX-8DR/DE trans-
mits an APRS beacon when your movement 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 APRS/
GPS Set Mode Item 10: APRS UNIT.
SLOW RATE: This item designates the transmission interval time of the APRS beacon at
low movement speeds.
FAST RATE: This item designates the maximum transmission interval time of the APRS
beacon at high movement speeds.
TURN ANGL: This item designates the course change angle that indicates a progress
heading change.
TURN SLOP: This item sets a coefficient to modify the TURN ANGLE algorithm, thus
increasing the beacon rate for lower movement 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 bea-
con. The VX-8DR/DE does not transmit an APRS beacon until this set-
ting time has elapsed since the previous APRS beacon transmission, pre-
venting too frequent beacon transmissions.
