See the
NOAA Weather
Radio Homepage for more information.
Frequencies are in MHz. Modulation is
16KF3E or 16KG3E.
NOTE: Once contact is made on a
hailing frequency, boaters should switch to a working frequency to engage
in conversation. This practice should keep the hailing frequencies
relatively clear of "idle chatter".
Note that the letter "A" indicates simplex
use of the ship station transmit side of an international duplex channel,
and that operations are different than international operations on that
channel. Some VHF transceivers are equipped with an "International - U.S."
switch for that purpose. "A" channels are generally only used in the
United States, and use is normally not recognized or allowed outside the
U.S. The letter "B" indicates simplex use of the coast station transmit
side of an international duplex channel. The U.S. does not currently use
"B" channels for simplex communications in this band.
Boaters should normally use channels listed
as Non-Commercial. Channel 16 is used for calling other stations or for
distress alerting. Channel 13 should be used to contact a ship when there
is danger of collision. All ships of length 20m or greater are required to
guard VHF channel 13, in addition to VHF channel 16, when operating within
U.S. territorial waters. Users may be fined by the FCC for improper use of
these channels. See
Marine Radio Watch Requirements for further information.
The chart below summarizes a
portion of the FCC rules -- 47 CFR 80.371(c) and 80.373(f)
