time clock. If 7 days have elapsed without a time sync, then the GPS receiver will stay powered
up continuously trying to re-sync again. If the GOES Time is not displayed or not incrementing
every second as expected, the radio has not acquired time from the GPS system. This is common
at initial power up. The radio will not transmit if the time has not been acquired initially or if it
has been more than 7 days since the last GPS time sync.
Enable GOES GPS: This box should always remain checked, indicating the Radio is using the
time acquired by the GPS system. The time can be manually set, however, and maintained by the
System 5000
though doing so is strongly discouraged as the GPS system is more accurate. To
TM
disable the GPS from setting the time, uncheck this box and press OK to save the changes.
System 5000 Time: Displays the current time on the System 5000 .
TM
Synchronize: Though set to (None) by default, the System 5000 can be set to synchronize with
TM
the GOES time due to the accuracy of the GPS system. A positive or negative Offset from the
GOES time can also be specified, if desired, to set a local time on the System 5000

GOES Self-Timed Options
Channel Number: Defines the Self-Timed Transmission channel number assigned by NOAA.
The range for use with the domestic satellites is 001 to 199 and represents a specific frequency
for communicating with the satellites. If the channel is an even number it is communicating with
the western satellite. If the channel number is odd it is communicating with the eastern satellite.
Channels from 200 and above are for international use.
Baud Rate: Defines the baud rate for Self-Timed transmissions. This may be different than the
Random transmission baud rate. Valid options are 100, 300 or 1200 baud. This will also be
assigned by NOAA.
