AS/NZS ETSI EN 301 025:2018
VHF radiotelephone equipment for general communications and associated equipment for Class ‘D’ Digital Selective Calling (DSC)
Specifies the minimum requirements for general communication for shipborne fixed installations using a very high frequency (VHF) radiotelephone operating in certain frequency bands allocated to the maritime mobile service using either 25 kHz or 25 kHz and 12.5 kHz channels and associated equipment for DSC—class D. This standard does not cover requirements for the integrated GNSS receiver providing locating function. Identical with, and reproduced from, ETSI EN 301 025 V2.2.1 (2017-03).
