Table 6-1 (Continued)

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.

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.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.Channel 17 may also be used for on-board communications provided the effective radiated power does not exceed 1 Watt.

5.Channel 70 is to be used exclusively for digital selective calling (DSC) for distress and safety.

6.Channels 75 and 76 are receive-only. Transmission on these channels has bees disabled as a precaution to avoid harmful interference to Channel 16.

CAUTION

Operation on channels not designated for use by your classification of craft or on International Channels within the US territorial waters is a violation of FCC Rules and Regulations and way result in severe penalties.
