This Marine Guidance Note draws attention to the changes made in the Radio Regulations (Appendix 17 and 18) affecting VHF and HF 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.
