MARINE VHF RADIO

The fairly common Marine VHF Radio - Icom M80 H

Description

Describe VHF radio, it's uses, etc

Procedures

The use of VHF radio requires certain protocol - see the [FCC's] Website (which covers HF Marine Radio as well)

Marine VHF Frequencies & Channels

VHF CHANNELS & FREQUENCIES AND THEIR USE
Note:-The Channel numbers run from 01A >>>>88A (in the Left hand Column). The frequencies In Mega Hertz (MHz) are given for each designated channel, first the transmit MHZ then the Receive MHz. Against each channel is the authorised use for that channel.
Sub-note:- The underlisted are those that are found in most VHF marine radios that are marketed today - 'some earlier models will not have all the US channels and frequencies'.

NOAA Weather Radio Frequencies
Channel Frequency (MHz)
WX1 162.550
WX2 162.400
WX3 162.475
WX4 162.425
WX5 162.450
WX6 162.500
WX7 162.525

See 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.
