From 10am on 6th September 2017, there will be changes to some VHF channel numbers used to contact the UK Coastguard.
The changes to Appendix 18 (Marine VHF) of the Radio Regulations mean that existing channels will no longer be used for either Maritime Safety Information (MSI) or Radio Medical Advice.
Currently, VHF channels 23, 84 and 86 are used for these two services.
But from 6 September 2017, the channels to use will be VHF 62, 63 and 64.
The use of VHF Channel 10 for MSI and pollution control (back up) is unchanged.
Mark Lawson from the Maritime and Coastguard Agency said: "This is an absolute changeover so people do need to be ready to start using the channels from 10am on 6th September," he stressed.
"Although the MCA will keep the existing channels for about a year, they will not be routinely monitored. Your existing VHF radios should already have the new channels, but owners should check".
Why are the channels changing?
The changes are as a result of the World Radio Conference where it was decided that some channels should be removed and allocated for digital use. It’s a simple change to other VHF frequencies.
What difference will it make to boat owners and operators?
There will be no difference to the service provided. MSI broadcasts will still go out at the existing published times, just on the new channels. Those listening on Channel 16 will be directed to the appropriate channel, when the forthcoming broadcast is to be made.
What will happen if I use the old channels after 6th September?
The old channels will be retained by the Maritime & Coastguard Agency for about a year. However, they will not be routinely monitored as the MCA will redirect people to the appropriate channel that the MSI broadcast will be made on. Boat owners requiring Radio Medical Advice should initially call on Channel 16. They will then be directed to a working channel (62, 63 or 64).
What should boat owners and operators be doing?
Make a note of the replacement channels so that they are ready for the changeover day. Your existing VHF radios should already have the new channels, but owners should check.
