implementation of 12.5 kHz channel interleaving and
consequential national requirements shall be subject to
coordination with affected administrations. (WRC-12)
Specific notes
f) The frequencies 156.300 MHz (channel 06), 156.525 MHz (channel
70), 156.800 MHz (channel 16), 161.975 MHz (AIS 1) and 162.025 MHz
(AIS 2) may also be used by aircraft stations for the purpose of search
and rescue operations and other safety-related communication.
(WRC-07)
g) Channels 15 and 17 may also be used for on-board communications
provided the effective radiated power does not exceed 1W, and
subject to the national regulations of the administration concerned
when these channels are used in its territorial waters.
h) Within the European Maritime Area and in Canada, these
frequencies (channels 10, 67, 73) may also be used, if so required,
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, under the conditions specified in
Nos. 51.69, 51.73, 51.74, 51.75, 51.76, 51.77 and 51.78.
i) The preferred first three frequencies for the purpose indicated in
Note a) are 156.450 MHz (channel 09), 156.625 MHz (channel 72) and
156.675 MHz (channel73).
j) Channel 70 is to be used exclusively for digital selective calling for
distress, safety and calling.
k) Channel 13 is designated for use on a worldwide basis as a
navigation safety communication channel, primarily for intership
navigation safety communications. It may also be used for the ship
movement and port operations service subject to the national
regulations of the administrations concerned.
l) These channels (AIS 1 and AIS 2) are used for an automatic
identification system (AIS) capable of providing world wide
operation, unless other frequencies are designated on a regional
basis for this purpose. Such use should be in accordance with the
most recent version of Recommendation ITU-RM.1371. (WRC-07)
m) These channels may be operated as single frequency channels,
subject to coordination with affected administrations. The following
conditions apply for single frequency usage:
