Appendix B: Channel List 61
• 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.
• Channels 10, 67 and 73 should be avoided within VHF range of coastal areas in Europe and Canada.
• 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 in
coordinated 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 break-
ers and assisted ships during ice seasons.
2. Channels 10 or 73 (depending on location) are also used for the broadcast of Marine Safety Infor-
mation 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 chan-
nel, 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 lim-
ited to 1 Watt.
