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 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 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.
