MSC.1/Circ.1460/Rev.3 – ITU Radio Regulations impact on VHF Radios

Dear valued Customers,

Greetings from Master Systems!!

MSC.1/Circ.1460/Rev.3 / ITU Radio Regulations impact on VHF radios  will be implemented soon. Based on this new regulation, the first radio survey which will take place after 1st of January 2024, all VHFs have to comply with the appendix 18 of the Radio Regulations, which require 4-digit channels to be available on the fixed VHFs on board

The Maritime Safety Committee of IMO recognized that incompatibility might exist between VHF radio-communication equipment installed on ships and onshore and the revised frequencies and channeling arrangements for the maritime VHF bands as contained in appendix 18 to the ITU Radio Regulations (RR) – Edition 2020. 


ITU made extensive changes to appendix 18 of the Radio Regulation which can be found here. These changes do not affect the GMDSS but the use of other frequencies for VHF meteorological, navigational, and urgent marine information broadcasts, port operations, and Vessel Traffic Service (VTS). According to the Performance standards for shipborne VHF radio installations capable of communication and digital selective calling (resolution A.803(19), as amended), VHF radio communication equipment should comply with the RR. The table below indicate the new channel list:

OEM’s (JRC, Furuno, Sailor, NSR etc..) has announced that some older VHFs type will not be supported, the newer models will need software upgrade. Please refer to the table below for analytical guidance from different manufacturers.
