+ | Known as SSB (single sideband) radios in the sailing community, these radios provide both voice and data communications over thousands of miles utilizing HF, or high frequency, and MF, or medium frequency, spectrum. Marine MF/HF radios, when properly configured with a unique [[MMSI]] and connected to a [[GPS]], are a part of the Global Maritime Distress Safety System ([https://secure.wikimedia.org/wikipedia/en/wiki/Global_Maritime_Distress_Safety_System GMDSS]) utilizing Digital Selective Calling ([[DSC]]). | ||
- | |||
- | |||
- | + | Although Marine HF radio commonly called SSB in some sailing circles. SSB, however, identifies the modulation of the transmission and not the actual frequencies used. This would be akin to calling your VHF radio your FM radio. "[[Marine HF Radio]]" is probably a better term to use. | |
- | + | Unlike [[Ham_Radio|Amateur Radio]], marine MF/HF radios use [http://www.navcen.uscg.gov/?pageName=mtHighFrequency specific channels] for communicating - similar to the marine VHF radio. Some channels are designated for distress and safety calling while others can be used to contact commercial shore stations that provide telephone and data connectivity. Prior to transmitting on a channel it is important to understand the purpose of the channel to avoid interfering with other communications. | |
- | + | Older HF radios are often controlled by a single crystal to tune each channel and are thus limited to specific frequencies, and do not have DSC capability. This is the kind of radio one is most likely to find aboard a non-commercial vessel such as a cruising yacht. It is important therefore to know which frequencies are monitored in the area in which you're sailing, and to learn the correct emergency calling procedures. | |
- | + | ||
- | + | Other services found on marine HF and MF frequencies are weather broadcasts directly from government sources in the form of voice, [[SITOR]], and [[Weatherfax|facsimile]] formats. These broadcasts can be received with a simple shortwave receiver or a computer with a sound card. | |
- | + | ||
- | + | ||
- | + | Many sailors keep in contact with each other and shore stations by the use of [[World_MM_Nets#Marine_Nets|nets]]. These ''nets'' are simply a time of day when volunteer shore operators will monitor a certain frequency to hear if there is anyone trying to make contact with them. Nets may also pass weather information and can be useful for asking specific questions about the conditions in certain locations. A good net operator will also keep track of who is in their area and alert rescue operations if a vessel hasn't called in for some time after expecting to hear from them. | |

- | + | ||
- | + | ||
- | == | + | ==Licensing== |
- | + | Operation of a HF/MF marine radio requires a [[Radio_Licencing|licence]]. This licence allows you to not only transmit your HF/MF radio in your country's home waters but also in international waters and waters of other countries. It should be noted that in a dire emergency where life is at risk it is allowable to transmit an emergency message on any frequency and that licencing is a secondary issue. However, stiff penalties apply to any person doing so if it is subsequently found to be unnecessary, since valuable resources needed for real emergencies could be wasted. | |

- | === | + | ==Shore Stations== |
- | + | This list of shore stations is mostly for historical interest. As of 1999, WCC, WOM, and KMI are no longer in service, and WLO frequencies have not been updated since 2003. In the intervening time many of the stations have been moved, closed, or replaced. | |

- | + | ==Frequencies== | |
+ | ===Frequency Bands=== | ||
+ | A typical [[Ham Radio]] can tune to any frequency between 2MHz and 32MHz with some Ham Radios capable of lower or higher frequencies in that range. The frequency band chosen will depend on propagation at a given time of day, agreed times for radio nets, etc. | ||
+ | Marine HF/MF Radios are restricted to tuning in the following frequency bands: | ||
- | + | * 2 MHz (MF) | |
- | + | * 4 MHz (this and beyond is HF) | |
+ | * 6 MHz | ||
+ | * 8 MHz | ||
+ | * 12 MHz | ||
+ | * 16 MHz | ||
+ | * 18 MHz | ||
+ | * 22 MHz | ||
+ | * 25 MHz | ||
+ | |||
+ | ===Emergency Frequencies=== | ||
+ | In accordance with the [https://secure.wikimedia.org/wikipedia/en/wiki/Global_Maritime_Distress_Safety_System GMDSS] the following frequencies will be utilized for distress calling globally: | ||
+ | |||
+ | ===Voice (SSB)=== | ||
+ | * 2,182 (AM or SSB) | ||
+ | * 4,125 | ||
+ | * 6,215 | ||
+ | * 8,291 | ||
+ | * 12,290 | ||
+ | * 16,420 | ||
+ | |||
+ | ===DSC=== | ||
+ | * 2,187.5 | ||
+ | * 4,207.5 | ||
+ | * 6,312.0 | ||
+ | * 8,414.5 | ||
+ | * 12,557.0 | ||
+ | * 16,804.5 | ||
+ | |||
+ | ===Operational Frequencies=== | ||
+ | Operational frequencies are commonly assigned to a channel, which can be selected on a rotary dial on a marine HF/MF radio. Channel selection may vary from radio to radio, and some radios will have programmable channels, but the following list comes from the ITU and would normally be programmed into a radio as a default set: | ||

Known as SSB (single sideband) radios in the sailing community, these radios provide both voice and data communications over thousands of miles utilizing HF, or high frequency, and MF, or medium frequency, spectrum. Marine MF/HF radios, when properly configured with a unique MMSI and connected to a GPS, are a part of the Global Maritime Distress Safety System (GMDSS) utilizing Digital Selective Calling (DSC).
Although Marine HF radio commonly called SSB in some sailing circles. SSB, however, identifies the modulation of the transmission and not the actual frequencies used. This would be akin to calling your VHF radio your FM radio. "Marine HF Radio" is probably a better term to use.
Unlike Amateur Radio, marine MF/HF radios use specific channels for communicating - similar to the marine VHF radio. Some channels are designated for distress and safety calling while others can be used to contact commercial shore stations that provide telephone and data connectivity. Prior to transmitting on a channel it is important to understand the purpose of the channel to avoid interfering with other communications.
Older HF radios are often controlled by a single crystal to tune each channel and are thus limited to specific frequencies, and do not have DSC capability. This is the kind of radio one is most likely to find aboard a non-commercial vessel such as a cruising yacht. It is important therefore to know which frequencies are monitored in the area in which you're sailing, and to learn the correct emergency calling procedures.
Other services found on marine HF and MF frequencies are weather broadcasts directly from government sources in the form of voice, SITOR, and facsimile formats. These broadcasts can be received with a simple shortwave receiver or a computer with a sound card.
Many sailors keep in contact with each other and shore stations by the use of nets. These nets are simply a time of day when volunteer shore operators will monitor a certain frequency to hear if there is anyone trying to make contact with them. Nets may also pass weather information and can be useful for asking specific questions about the conditions in certain locations. A good net operator will also keep track of who is in their area and alert rescue operations if a vessel hasn't called in for some time after expecting to hear from them.
Licensing
Operation of a HF/MF marine radio requires a licence. This licence allows you to not only transmit your HF/MF radio in your country's home waters but also in international waters and waters of other countries. It should be noted that in a dire emergency where life is at risk it is allowable to transmit an emergency message on any frequency and that licencing is a secondary issue. However, stiff penalties apply to any person doing so if it is subsequently found to be unnecessary, since valuable resources needed for real emergencies could be wasted.
Shore Stations
This list of shore stations is mostly for historical interest. As of 1999, WCC, WOM, and KMI are no longer in service, and WLO frequencies have not been updated since 2003. In the intervening time many of the stations have been moved, closed, or replaced.
Call Sign | Station Location |

KMI | Inverness, California |
WOM | Ft Lauderdale, Florida |
WOO | Manahawkin, New Jersey |
WLO | Mobile, Alabama |
KLB | Seattle, Washington |
WSC | Tuckerton Radio |
KPH | San Francisco, California |
VCT | St John's, Newfoundland |

Frequencies
Frequency Bands
A typical Ham Radio can tune to any frequency between 2MHz and 32MHz with some Ham Radios capable of lower or higher frequencies in that range. The frequency band chosen will depend on propagation at a given time of day, agreed times for radio nets, etc.
Marine HF/MF Radios are restricted to tuning in the following frequency bands:
- 2 MHz (MF)
- 4 MHz (this and beyond is HF)
- 6 MHz
- 8 MHz
- 12 MHz
- 16 MHz
- 18 MHz
- 22 MHz
- 25 MHz
Emergency Frequencies
In accordance with the GMDSS the following frequencies will be utilized for distress calling globally:
Voice (SSB)
- 2,182 (AM or SSB)
- 4,125
- 6,215
- 8,291
- 12,290
- 16,420
DSC
- 2,187.5
- 4,207.5
- 6,312.0
- 8,414.5
- 12,557.0
- 16,804.5
Operational Frequencies
Operational frequencies are commonly assigned to a channel, which can be selected on a rotary dial on a marine HF/MF radio. Channel selection may vary from radio to radio, and some radios will have programmable channels, but the following list comes from the ITU and would normally be programmed into a radio as a default set:
