MGN 562 (M+F) Radio – Radio Regulations Amendments and GMDSS Radio Equipment Updates (link)
This Marine Guidance Notes draws attention to the changes made in the Radio Regulations (Appendix 17 and 18) which come into force 1st January 2017 affecting VHF and HF radio communications and equipment. The Maritime and Coastguard Agency does not require the replacement of marine radio equipment installed and used on board. It is, however, the responsibility of a vessel’s owner to consider, based upon the area of operation, whether an update or replacement of the on-board radio equipment is necessary.
