Theses are the International Marine VHF Channels,
as used by UK Coastguard. Note that Canadian and US Coastguards
will use different channels.
Use Channel 16 for Initial Calling, and for
Distress and Safety Calling. Once contact is established, the
station called will nominate a Working Channel on which the
contact is then continued. Note that after the initial contact,
the stations must switch to a Working Channel, except
for safety matters. Working Channels are noted below in bold.
It is advised to keep the Channels used by UK Coastguard clear,
they will probably direct you to one of them for routine traffic.
Channel 13 is designated for intership safety
of navigation (sometimes known as "bridge to bridge")
and may be a possible channel for calling a merchant ship if
no contact on channel 16.
Are you close enough to use "low-power"
(1 watt)? - Doing so saves your battery and also reduces the
range your signal achieves - this prevents the channel being
cluttered and helps other people access it.
Channel 70 is exclusively for DSC calling for
safety and emergency and must not be used for other purposes.
