9.3 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks and bridges and by vessels maneuvering in
port. Messages on this channel must concern navigation only, such as meet-
ing and passing in restricted waters.
Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your
radio is programmed to automatically reduce power to this limit on these
channels. However, in certain situations it may be necessary to temporarily
use a higher power. See page 16 (

key) for means to temporarily over-
ride the low-power limit on these two channels.
9.4 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requir-
ing vessels at sea (or other bodies of water) to be notified, the NOAA (Na-
tional Oceanographic and Atmospheric Administration) broadcasts a 1050
Hz tone that some VHF radios, including your HX600S, can detect for
“Weather Alarm” purposes (refer to section 6.4.1 “NOAA WEATHER ALERT”
for a discussion of how to use this feature). The 1050 Hz tone, when de-
tected, will produce a loud beep in the speaker of the HX600S, to signal that
a Weather Alert Broadcast is being received.
In order to test this system, NOAA broadcasts the 1050 Hz tone every Wednes-
day sometime between 11 AM and 1 PM local time. You may use this oppor-
tunity to test your HX600S periodically to confirm that the Weather Alert fea-
ture is working, or for training crewmembers on how to configure the HX600S
to receive the NOAA Weather Alerts.
