time
DSC logs are
sorted with
wrong time
stamp or
radio time is
incorrect
A wrong radio time indication should occur only
if GPS position source is not connected or
providing correct time data. A valid GPS time
signal will update the UTC time used for time
stamping the DSC logs.
If a GPS/position source is not connected to the
VHF radio and hence position and time is entered
manually, you must enter the "radio time" also
manually, at least after power up. This will ensure
correct time stamping of the DSC logs.
The UTC time is the suggested time to be entered
when prompted for entering position and time
manually (every four hours).
