From 1 January 2017, the frequency bands 157.200-157.325 MHz
and 161.800-161.925 MHz (corresponding to channels: 24, 84, 25,
85, 26 and 86) are identified for the utilization of the VHF Data
Exchange System (VDES) described in the most recent version of
Recommendation ITU-R M.2092. These frequency bands may also be
used for analogue modulation described in the most recent version
of Recommendation ITU-R M.1084 by an administration that wishes
to do so, subject to not causing harmful interference to, or claiming
protection from other stations in the maritime mobile service using
digitally modulated emissions and subject to coordination with
affectedadministrations. (WRC-15)
ww. In Region 2, the frequency bands 157.200-157.325 and 161.800-
161.925 MHz (corresponding to channels: 24, 84, 25, 85, 26
and 86) are designated for digitally modulated emissions in
accordance with the most recent version of Recommendation
ITU-R M.1842.
In Canada and Barbados, from 1 January 2019 the frequency
bands 157.200-157.275 and 161.800-161.875 MHz (corresponding
to channels: 24, 84, 25 and 85) may be used for digitally
modulated emissions, such as those described in the most
recent version of Recommendation ITU-R M.2092, subject to
coordination with affected administrations.
(WRC-15)
x) From 1 January 2017, in Angola, Botswana, Lesotho, Madagascar,
Malawi, Mauritius, Mozambique, Namibia, Democratic Republic of
the Congo, Seychelles, South Africa, Swaziland, Tanzania, Zambia
and Zimbabwe, the frequency bands 157.125-157.325 and 161.725-
161.925 MHz (corresponding to channels: 82, 23, 83, 24, 84, 25, 85, 26
and 86) are designated for digitally modulated emissions.
From 1 January 2017, in China, the frequency bands 157.150 -
157.325 and 161.750 - 161.925 MHz (corresponding to channels: 23,
83, 24, 84, 25, 85, 26 and 86) are designated for digitally modulated
emissions. (WRC-12)
y) These channels may be operated as single or duplex frequency
channels, subject to coordination with affected administrations.
(WRC-12)
z) Until 1 January 2019, these channels maybe used for possible testing
of future AIS applications without causing harmful interference
to, or claiming protection from, existing applications and stations
operating in the fixed and mobile services.
