INTERNATIONAL VHF MARINE RADIO CHANNELS AND FREQUENCIES

The following table is adapted from the International Telecommunications Union Radio Regulations Appendix 18, including changes adopted by the 2015 World Radio Conference. Transmission on frequencies or channels shown in blue are not allowed within U.S. territorial waters, but are allowed on the high seas and in most other countries. Note that a marine radio operating in the international mode on a channel in which the ship station frequency is shown in black and the shore station frequency shown in blue would not be able to communicate with a U.S. shore station. Frequencies and channels shown in green were auctioned in the U.S. and are only available from the auction winner. The large number of blue channels and frequencies indicates the shortage of VHF maritime spectrum in the U.S. compared to most other maritime countries.

The Table below defines the channel numbering for maritime VHF communications based on 25 kHz channel spacing and use of several duplex channels. The channel numbering and the conversion of two-frequency channels for single-frequency operation shall be in accordance with Recommendation ITU-R M.1084-5 Annex 4, Tables 1 and 3. The Table below also describes the harmonized channels where the digital technologies defined in the most recent version of Recommendation ITU-R M.1842 could be deployed.

See the U.S. VHF Marine Radio Frequencies and Channels

(Source: Final Acts WRC-14 World Radio Conference, Geneva 2015)

 

Half-duplex channels here are listed with the A and B frequencies the same. The frequencies, channels, and some of their purposes are governed by the ITU. For an authoritative list see.[3] The original allocation of channels consisted of only channels 1 to 28 with 50 kHz spacing between channels, and the second frequency for full-duplex operation 4.6 MHz higher.

Improvements in radio technology later meant that the channel spacing could be reduced to 25 kHz with channels 60 to 88 interspersed between the original channels.

Channels 75 and 76 are omitted as they are either side of the calling and distress channel 16, acting as guard channels. The frequencies which would have been the second frequencies on half-duplex channels are not used for marine purposes and can be used for other purposes that vary by country. For example, 161.000 to 161.450 MHz are part of the allocation to the Association of American Railroads channels used by railways in the USA and Canada.[4]

[9] Notes:

  1. Some radios enable channels 3A, 61A, and 64A when configured for "USA mode" even though those channels are allocated exclusively for Public Safety use by the FCC. The frequencies 156.075, 156.150, and 156.225 MHz are used for interoperability communication by police and fire departments in many areas.
  2. Channel 22A is reserved for communication between the U.S. Coast Guard vessels and private vessels. The Coast Guard does not monitor 22A: Contact must first be established on 16.
  3. UKSAR land-based search and rescue teams have access to the half-duplexed versions of 24, 62, 63, 64, 85 for operational and training needs. These include mountain rescue teams in England, Wales and Scotland.
  4. CCG public operations moved from 22A to 04A to avoid interference from USCG stations in northern Washington state.

Operating procedure[edit]

The accepted conventions for use of marine radio are collectively termed "proper operating procedure". These international conventions include:

  • Stations should listen for 30 seconds before transmitting and not interrupt other stations.
  • Maintaining a watch listening on Channel 16 when not otherwise using the radio. All calls are established on channel 16, except for distress working switch to a working ship-to-ship or ship-to-shore channel. (procedure varies in the U.S. only when calls can be established on Ch. 9)
  • During distress operations silence maintained on ch 16 for other traffic until the channel is released by the controlling station using the pro-word "Silence Fini". If a station does use Ch 16 during distress operations controlling station issues the command "silence mayday".
  • Using a set of international "calling" procedures such as the "Mayday" distress call, the "Pan-pan" urgency call and "Sécurité" navigational hazard call.
  • Using "pro-words" based on the English language such as Acknowledge, All after, All before, All stations, Confirm, Correct, Correction, In figures, In letters, Over, Out, Radio check, Read back, Received, Repeat, Say again, Spell, Standby, Station calling, This is, Wait, Word after, Word before, Wrong (local language is used for some of these, when talking to local stations)
  • Using the NATO phonetic alphabetAlfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu
  • Using a phonetic numbering system based on the English language or a combination of English and Roman languagesWun, Too, Tree, Fow-er, Fife, Six, Sev-en, Ait, Nin-er, Zero, Decimal; alternatively in marine communication: unaone, bissotwo, terrathree, kartefour, pantafive, soxisix, setteseven, oktoeight, novenine, nadazero

Slightly adjusted regulations can apply for inland shipping, such as the Basel rules in Western Europe.
