12、 Information, Frequencies, & ChartsFrequencies are in MHz. Modulation is 16KF3E or 16KG3E.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 tra
13、nsceivers 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
14、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 col
15、lision. 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.See the Federal
16、 Communications Commissions Marine VHF Radio Channels page. The FCC page does not include frequency information, but has more complete information on the use of the channels.
