CSN ETSI EN 301 025 V2.3.1 The present document specifies technical characteristics and methods of measurements for VHF radiotelephone with the following characteristics: - operating in the channels and frequencies specified in the ITU Radio Regulations appendix 18 [1] as applicable, 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; - capable of operating on single frequency and two-frequency channels with manual control (simplex); - supporting dual frequency simplex operation only; - using phase modulation, G3E (frequency modulation with pre-emphasis of 6 dB/octave) for speech, and G2B for DSC signalling. Full duplex operation is not supported. The present document does not provide technical requirements for conformance with the essential requirements of Directive 2014/53/EU [i.3] for any integrated GNSS receiver providing locating function. NOTE 1 - Additional VHF channels for maritime use outside those defined by appendix 18 to the ITU Radio Regulations [1] may also be provided where permitted by administration. NOTE 2 - The relationship between the present document and essential requirements of article 3.2 and article 3.3(g) of Directive 2014/53/EU [i.3] is given in annex A.
