ADDITIONAL FEATURES
• Auto Request (GDL 49 Only) - This field is
used to set the time interval for the GDL 49 to
automatically send a NEXRAD data request. The
time options are OFF, 10 min, 15 min, 20 min, 30
min, 45 min, and 1 hour. When an auto request
time is selected, the first request is sent after the
specified time has elapsed from when the field
was set (as opposed to immediately sending a
request).
NOTE: It is recommended that the pilot turn the
Auto Request function on by setting it to ‘10 min’
updates. This setting provides best performance
for the GDL 49.

Request?’ (GDL 69) field is used to request
NEXRAD Data.
