• Auto Request - This field is used to set the
time interval for the system to automatically
send the position. The time options are OFF,
10 min, 15 min, 20 min, 30 min, 45 min, and
1 hr. When an auto request time is selected,
the first report is sent after the specified
time has elapsed from when the field was
set (as opposed to immediately sending a
report). Note that in order to take advantage
of EchoFlight’s Automatic Weather Delivery
(AWD) service, the time interval must be set
to 15 minutes.
• Manual Send? - This field is used to send out a
current single position report (Figure 11-41).
