ing DGPS corrections from the selected station in manual
tuning mode. You might see the label Tracking, which
indicates that a MSK beacon signal is present but DGPS
corrections are not being received. This is usually caused
by high noise on the beacon receiver or external device.
If you press the EDIT key, you can select between
Automatic beacon search mode, Manual beacon tuning
mode, or Off. When the receiver is in the Manual tun-
ing mode, you can use the cursor key to scroll down
into the large window below Station Selection and edit
the Reference Station name. The name you enter will
always be associated with the frequency to which you
programmed the receiver. If you move to another region
that uses a frequency and name you previously entered,
the receiver will display the previously entered name.
You can enter a new name for any manually tuned fre-
quency at any time.
Use the cursor key to move down the screen again and
program the frequency you desire. The receiver will au-
tomatically update the Station ID. If the beacon station
is transmitting its location, the receiver will calculate the
distance between the reference station and the receiver,
otherwise this will be blank. You can usually find current
beacon status, location, and operating information from
the governing country’s Coast Guard or Maritime Safety
Administration. You will find a list of known beacon
stations in Appendix B - Beacon List at the end of this
manual. This list may be incomplete at your location, in
which case we encourage you to contact the appropriate
governing agency.
