• Intership channels are for communications between ship stations. Intership communications
should be restricted to Channels 6, 8, 72 and 77. If these are not available, the other channels
marked for Intership may be used.
• Channel 70 is used exclusively for Digital Selective Calling (DSC) and is not available for regular
voice communications.
Notes:
1. Channel 06 may also be used for communications between ship stations and aircraft engaged incoordinated
search and rescue operations. Ship stations should avoid harmful interference to such communications on
channel 06 as well as to communications between aircraft stations, ice breakers and assisted ships during ice
seasons.
2. Within the European Maritime Area and in Canada, channels 10, 67 and 73 may also be used by
the individual administrations concerned for communication between ship stations, aircraft stations and
participating land stations engaged in coordinated search and rescue and anti-pollution operations in local
areas. Channels 10 or 73 (depending on location) are also used for the broadcast of Marine Safety Information
by the Maritime and Coast Guard Agency in the UK only.
3. Channel 13 is designated for use on a worldwide basis as a navigation safety communication
channel, primarily for intership navigation safety communications.
4. Channels 15 and 17 may also be used for on-board communications provided the effective radiated power
does not exceed 1 Watt.
5. The use of Channels 75 and 76 should be restricted to navigation related communication only
and all precautions should be taken to avoid harmful interference to channel 16. Transmit power is limited to 1
Watt.
