AIS 1 161.975 161.975 Automatic Identification System (AIS) PLEASE NOTE 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. See NATIONAL WEATHER SERVICE MARINE PRODUCTS VIA NOAA WEATHER RADIO and the NOAA Weather Radio Homepage for more information. Additional Information, Frequencies, & Charts Frequencies 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 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. See the Federal Communications Commission's Marine VHF Radio Channels page. The FCC page does not include frequency information, but has more complete information on the use of the channels.
