Channel numbers, e.g. (WX1, WX2) etc. have no special
significance but are often designated this way in consumer
equipment. Other channel numbering schemes are also
prevalent.
The order of channels shown is the order they were established
and is slowly becoming less popular over time than a numerical
ordering of channels.

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
– US switch for that purpose. A channels are generally only
used in the United States, and use is normally not recognized
or allowed outside the US The letter B indicates simplex use
of the coast station transmit side of an international duplex
channel. The US 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 US territorial
waters. Users may be fined by the FCC for improper use of
these channels.
