Foreword
This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI), and
was adopted, having passed through the ETSI standards approval procedure, (Public Enquiry 19:
1991-05-13 to 1991-10-04, Vote 27: 1992-09-21 to 1992-11-13).
This ETS lays down minimum requirements for VHF radio transmitters and receivers operating on board
ships in certain frequency bands allocated to the maritime mobile service, and incorporates the requirements
of the relevant recommendations of the International Maritime Organization.

1 Scope
This ETS states the minimum requirements for VHF transmitters and receivers fitted with a 50 Ω external
antenna socket or connector for use on board ships and operating in the bands between 156 and 174 MHz
1)
allocated to the maritime mobile service by the Radio Regulations (see Radio Regulations, Appendices 18
[1] and 19 [2]). The relevant requirements detailed in the references in Clause 2, Normative References are
incorporated in this ETS.
2 Normative references
This ETS incorporates by dated or undated reference provisions from other publications. These normative
references are cited at the appropriate places in the text and the publications are listed hereafter. For dated
references, subsequent references to or revisions of any of these publications apply to this ETS only when
incorporated in it by amendment or revision. For undated references the latest edition of the publication
referred to applies.

the band 156-174 MHz for Stations in the Maritime Mobile Service".

Transmitters and Receivers used in the Maritime Mobile Service in the band

3 General requirements
3.1 Construction
The mechanical and electrical construction and finish of the equipment shall conform in all respects to good
engineering practice, and the equipment shall be suitable for use on board ships.

1 )
Use in certain inland waterways may impose additional requirements.

---------------------- Page: 11 ----------------------

SIST ETS 300 162 E1:2003
Page 10
ETS 300 162: October 1993
All controls shall be of sufficient size to enable the usual control functions to be easily performed and the
number of controls should be the minimum necessary for simple and satisfactory operation.
All parts of the equipment to be checked during inspection or maintenance operations shall be readily
accessible. The components shall be readily identifiable.
Full technical documentation shall be supplied with the equipment.
The VHF maritime mobile service uses both single-frequency and two-frequency channels. For
two-frequency channels the Radio Regulations require a separation of 4,6 MHz between the transmitting
frequency and the receiving frequency.
The equipment shall be capable of operating on single frequency and two-frequency channels with manual
control (simplex). It may also be capable of operating on two-frequency channels without manual control
(duplex).
The equipment shall be able to operate on all channels defined in Appendix 18 to the Radio Regulations [1].
Operation on channels 75 and 76 shall be prevented by appropriate means. Additional VHF channels outside
those defined by Appendix 18 to the Radio Regulations [1] may also be provided, but means shall be
provided to block any or all of these additional channels, as may be required by an Administration, before
installation on board ships. It shall not be possible for the user to unblock or block these additional channels.
The equipment shall be so designed that use of channel 70 for purposes other than Digital Selective Calling
(DSC) is prevented.
It shall not be possible to transmit while any frequency syntheziser used within the transmitter is out of lock.
It shall not be possible to transmit during channel switching operations.
3.2 Controls and indicators
The equipment shall have a channel selector and shall indicate the designator, as shown in Appendix 18 to
the Radio Regulations [1], of the channel at which the installation is set. The channel designator shall be
legible irrespective of the external lighting conditions.
Where practicable, channels 16 and 70 should be distinctively marked. Selection of channel 16, and if
possible channel 70, shall preferably be by readily accessible means (e.g. a distinctively marked key). Where
an input panel on the equipment for entering the digits 0 - 9 is provided, this shall conform to CCITT
Recommendation E.161 [3].
